Description
Technical Field
[0001] This application relates to the field of vehicle technology, and in particular to a flow guiding device, control method and related products. Background Technology
[0002] Aerodynamic devices are a type of device used to guide airflow to meet driving requirements. Taking a vehicle as an example, aerodynamic devices are installed at specific locations on the vehicle body (such as the front, bottom, sides, and rear) to optimize airflow direction, thereby reducing wind resistance, improving driving stability, or improving the flow field around the vehicle body. Their core function is to guide airflow to meet the vehicle's driving needs.
[0003] Currently, commonly used air deflectors are generally fixedly installed under the front bumper of the vehicle (also known as front bumper air deflectors). Although they can effectively reduce resistance and increase downforce, with the widespread use of flat-bottomed skid plates in electric vehicles, the middle part of the traditional air deflector becomes a drag-inducing component, which cannot meet the driving needs of the new scenario.
[0004] Therefore, a feasible solution is urgently needed to meet the optimization requirements of air resistance when vehicles are in motion under different scenarios. Summary of the Invention
[0005] This application provides a flow guiding device, control method, and related products that can meet the optimization requirements of air resistance when a vehicle is in motion under different scenarios.
[0006] In a first aspect, embodiments of this application provide a flow guiding device applied to a first vehicle. The flow guiding device includes: at least one moving member, at least one driving member, a first flow guiding member, and two second flow guiding members. The first flow guiding member and the two second flow guiding members are respectively fixedly connected to the at least one moving member. The first flow guiding member is located between the two second flow guiding members, and the two second flow guiding members are respectively located in front of the left and right wheels of the first vehicle. The driving portion of the at least one driving member is connected to the at least one moving member. The at least one driving member is used to drive the at least one moving member to move the first flow guiding member to a first position posture, and / or the at least one driving member is used to drive the at least one moving member to move the two second flow guiding members to a second position posture.
[0007] This application provides a flow guiding device. Based on the positions of the left and right wheels of a first vehicle, the flow guiding components in the device are designed and arranged in segments, such that two second flow guiding components are located in front of the left and right wheels of the first vehicle, respectively, with the first flow guiding component positioned between the two second flow guiding components. Through this application embodiment, by adjusting the movement of the first flow guiding component to a first position and / or adjusting the movement of the second flow guiding component to a second position, the air resistance of the first vehicle in different scenarios can be optimized, thereby meeting the driving needs of different scenarios.
[0008] Optionally, the two second guide vanes can be located in front of the left and right front wheels of the first vehicle, respectively, or in front of the left and right rear wheels of the first vehicle, respectively. This application embodiment does not impose any limitation on this. Optionally, the length of the second guide vanes is related to the width of the wheels of the first vehicle, and can be determined according to the model of the first vehicle.
[0009] Optionally, the first guide vane can be located in the area between the left and right front wheels of the first vehicle, or in the area between the left and right rear wheels of the first vehicle; this embodiment does not impose any limitation on this. Optionally, the length of the first guide vane is related to the distance between the left and right wheels of the first vehicle, and can be determined according to the vehicle model.
[0010] Optionally, the meaning of the position and attitude of the first and second guide components can differ under different adjustment schemes. For example, in an adjustment scheme where the moving component is a rotating shaft, the rotation of the shaft drives the first guide component and the two second guide components to rotate, thereby adjusting the position and attitude of the first and second guide components. In this case, the position and attitude can include the angle of rotation of the guide components. As another example, in an adjustment scheme where the moving component is a lifting rod, the lifting of the lifting rod drives the first guide component and the two second guide components to rise and fall, thereby adjusting the position and attitude of the first and second guide components. In this case, the position and attitude can include the height of the rise and fall of the guide components.
[0011] In one possible implementation, the at least one moving component includes a rotating shaft, and at least one driving component is used to drive the rotating shaft to rotate, thereby causing the first guide component and two second guide components to rotate.
[0012] In this embodiment, at least one moving component includes a rotating shaft, which can be driven to rotate by at least one driving component. This rotating shaft, in turn, causes the first guide vane and two second guide vanes to rotate, thereby adjusting the position and orientation of the first and second guide vanes. This ensures that the position and orientation of the first guide vane differs depending on the vehicle's location within different scenarios. Through this embodiment, the position and orientation of the first and second guide vanes can be adjusted to optimize the air resistance of the first vehicle in different scenarios, thus meeting the driving requirements of various situations.
[0013] Optionally, since the first guide element and the two second guide elements are fixedly connected to the same rotating shaft, the first guide element and the two second guide elements will rotate at the same frequency in the same direction and at the same angle under the drive of the rotation of the shaft.
[0014] In one possible implementation, the first guide member includes a first guide plate and a second guide plate fixedly connected at a first included angle, and the second guide member includes a third guide plate and a fourth guide plate fixedly connected at a second included angle. The angle bisector of the first included angle forms a third included angle with the angle bisector of the second included angle.
[0015] In this embodiment, the first air guide includes two air guide plates, which are fixedly connected at a first included angle. The second air guide includes two air guide plates, which are fixedly connected at a second included angle. Furthermore, the bisector of the first and second included angles forms a third included angle, meaning that the two air guide plates in the first and second air guides, viewed from the side view of the air guide device, have a third included angle, i.e., they do not completely overlap. Through this embodiment, to address the different air resistance requirements of different parts of the first vehicle, the structures of the first and second air guides can be differentiated. Even if both the first and second air guides are fixedly connected to the same pivot, based on their differentiated structures, the positions and attitudes of the first and second air guides can be adjusted by rotation to meet the air resistance requirements of different parts of the first vehicle in different scenarios, thereby satisfying driving needs in different scenarios.
[0016] Optionally, since the two guide plates in the first guide member and the two guide plates in the second guide member have a third included angle in the side view of the guide device, and the first guide member and the second guide member are both fixedly connected to the same rotating shaft, under the drive of the rotation of the rotating shaft, no matter how the first guide member and the second guide member rotate, the two guide plates in the first guide member and the two guide plates in the second guide member will maintain the third included angle in the side view of the guide device.
[0017] Optionally, the guide plates in the first and second flow guides can be flat plates or curved plates; this embodiment does not impose any limitations on this. Optionally, when the guide plate in the first flow guide is a curved plate, each of the two guide plates in the first flow guide has a plane tangent to the curved surface at one end of the fixedly connected rotating shaft. The included angle between these two tangent planes can be regarded as the first included angle between the two guide plates in the first flow guide.
[0018] In one possible implementation, the first included angle, the second included angle, and the third included angle are equal.
[0019] In this embodiment, the first included angle, the second included angle, and the third included angle are equal. Optionally, the first included angle, the second included angle, and the third included angle are all 90°. In this case, the two guide plates in the first guide member are L-shaped, and the two guide plates in the second guide member are L-shaped.
[0020] In one possible implementation, the projections of the first and second guide vanes onto the reference plane are offset from each other, as are the projections of the third and fourth guide vanes onto the reference plane. The projections of the first and third guide vanes onto the reference plane coincide, while the projections of the second and fourth guide vanes onto the reference plane are located on opposite sides of the rotation axis. The reference plane is a plane perpendicular to the axial direction of the rotation axis.
[0021] In this embodiment, the projections of the first guide plate in the first guide member and the third guide plate in the second guide member onto the reference plane coincide, while the projections of the second guide plate in the first guide member and the fourth guide plate in the second guide member onto the reference plane are located on opposite sides of the rotating shaft. Through this embodiment, the structures of the first and second guide members can be differentiated to meet the varying air resistance requirements of different parts of the first vehicle. Even though both the first and second guide members are fixedly connected to the same rotating shaft, their differentiated structures allow for adjustment of their position and orientation by rotation, satisfying the air resistance requirements of different parts of the first vehicle in different scenarios, thereby meeting driving needs in various situations.
[0022] In one possible implementation, the distance between the driving portion of at least one of the driving members and the center point of the rotating shaft is less than a first threshold.
[0023] In this embodiment, the driving part of at least one driving member should be as close as possible to the center point of the rotating shaft, such that the distance between the driving part of at least one driving member and the center point of the rotating shaft is less than a first threshold. Thus, when at least one driving member drives the rotating shaft to rotate, the force exerted on the rotating shaft by the driving part of at least one driving member can be balanced, more effectively driving the first guide member and the two second guide members to rotate.
[0024] Optionally, the first threshold is not a fixed value and can be adjusted according to different scenarios to improve the force-bearing performance of the drive part of at least one drive member on the rotating shaft. This embodiment does not limit this.
[0025] In one possible implementation, the at least one moving member includes a first moving member and a second moving member, and the at least one driving member includes a first driving member and a second driving member. The first driving member is used to drive the first moving member to move, thereby driving the first guide member to move. The second driving member is used to drive the second moving member to move, thereby driving the two second guide members to move.
[0026] In this embodiment, at least one moving component includes a first moving component and a second moving component, and at least one driving component includes a first driving component and a second driving component. The first driving component can drive the first moving component to move, thereby moving the first guide component and adjusting its position and attitude. Alternatively, the second driving component can drive the second moving component to move, thereby moving the second guide component and adjusting its position and attitude. This ensures that the position and attitude of the first guide component and / or the second guide component differ depending on the vehicle's location in different scenarios. Through this embodiment, two driving components can drive two moving components, respectively adjusting the position and attitude of the first and second guide components to optimize the vehicle's air resistance in different scenarios and meet driving requirements in various situations.
[0027] Optionally, the first driving member and the second driving member can be connected to the same motor. Under the power output of the same motor, the first driving member and the second driving member drive the first moving member and the second moving member respectively, so as to drive the first guide member and the two second guide members to move. At this time, the first guide member and the two second guide members will move in the same direction with the same offset at the same frequency.
[0028] Optionally, the first driving component and the second driving component can be connected to different first and second motors, respectively. Under the power output by the first motor, the first driving component drives the first moving component to move, thereby driving the first guide component to move. Under the power output by the second motor, the second driving component drives the second moving component to move, thereby driving the two second guide components to move. At this time, the movement frequency, movement direction, and movement offset of the first guide component and the two second guide components may be the same or different.
[0029] In one possible implementation, the first moving member includes a first rotating shaft, and the second moving member includes a second rotating shaft. A first driving member drives the first rotating shaft to rotate, thereby causing the first guide member to rotate. A second driving member drives the second rotating shaft to rotate, thereby causing the two second guide members to rotate.
[0030] In this embodiment, the first moving component includes a first rotating shaft, and the second moving component includes a second rotating shaft. The first rotating shaft can be driven to rotate by a first driving component, thereby rotating the first guide component to adjust its position and attitude. Alternatively, the second rotating shaft can be driven to rotate by a second driving component, thereby rotating the second guide component to adjust its position and attitude. This ensures that the position and attitude of the first guide component and / or the second guide component differ depending on the vehicle's operating conditions. Through this embodiment, two rotating shafts can be driven by two driving components to adjust the position and attitude of the first and second guide components respectively, thereby optimizing the vehicle's air resistance in different scenarios and meeting driving requirements in various situations.
[0031] In one possible implementation, the first guide member includes a fifth guide plate, and the second guide member includes a sixth guide plate.
[0032] In this embodiment, the first guide vane includes a single guide plate, and the second guide vane also includes a single guide plate. Because the first and second guide vanes are fixedly connected to different rotating shafts, the positions and orientations of the first and second guide vanes can be adjusted by rotation to meet the different air resistance requirements of different parts of the first vehicle in different scenarios, thereby satisfying driving needs in various situations.
[0033] Optionally, since both the first and second air guides include a single air deflector, the first and second air guides need to be powered by different motors to meet the different air resistance requirements of different parts of the first vehicle. This results in different rotation frequencies, directions, or angles of the first and second air guides, in order to meet the air resistance requirements of different parts of the first vehicle in different scenarios.
[0034] Optionally, the guide plates in the first and second guide members can be flat plates or curved plates, and this embodiment does not limit them.
[0035] In one possible implementation, the distance between the driving part of the first driving member and the center point of the first rotating shaft is less than a second threshold, and / or the distance between the driving part of the second driving member and the center point of the second rotating shaft is less than a third threshold.
[0036] In this embodiment, the driving part of the first driving member should be as close as possible to the center point of the first rotating shaft, such that the distance between the driving part of the first driving member and the center point of the first rotating shaft is less than a second threshold. In this way, when the first driving member drives the first rotating shaft to rotate, the force exerted by the driving part of the first driving member on the first rotating shaft can be balanced, thus more effectively driving the first guide member to rotate. The driving part of the second driving member should be as close as possible to the center point of the second rotating shaft, such that the distance between the driving part of the second driving member and the center point of the second rotating shaft is less than a third threshold. In this way, when the second driving member drives the second rotating shaft to rotate, the force exerted by the driving part of the second driving member on the second rotating shaft can be balanced, thus more effectively driving the second guide member to rotate.
[0037] Optionally, the second threshold and the third threshold are not fixed values and can be adjusted according to different scenarios to improve the force-bearing performance of the drive unit on the rotating shaft. This embodiment does not limit this.
[0038] In one possible implementation, the first moving member includes a first lifting rod, and the second moving member includes a second lifting rod. A first driving member drives the first lifting rod to move up and down, thereby causing the first guide member to move up and down. A second driving member drives the second lifting rod to move up and down, thereby causing the two second guide members to move up and down.
[0039] In this embodiment, the first moving component includes a first lifting rod, and the second moving component includes a second lifting rod. The first lifting rod can be driven to rise and fall by a first driving component, thereby raising and lowering the first guide vane to adjust its position and attitude. Alternatively, the second lifting rod can be driven to rise and fall by a second driving component, thereby raising and lowering the second guide vane to adjust its position and attitude. This ensures that the position and attitude of the first guide vane and / or the second guide vane differ depending on the vehicle's location in different scenarios. Through this embodiment, two lifting rods can be driven by two driving components to adjust the position and attitude of the first and second guide vanes respectively, optimizing the vehicle's air resistance in different scenarios and meeting driving requirements in various situations.
[0040] In one possible implementation, the first flow guide includes a seventh flow guide plate, and the second flow guide includes an eighth flow guide plate.
[0041] In this embodiment, the first guide vane includes a single guide plate, and the second guide vane also includes a single guide plate. Through this embodiment, since the first and second guide vanes are fixedly connected to different lifting rods, the positions and attitudes of the first and second guide vanes can be adjusted by raising and lowering them respectively to meet the air resistance requirements of different parts of the first vehicle in different scenarios, thereby satisfying driving needs in different scenarios.
[0042] Optionally, since both the first and second air guides include a single air deflector, the first and second air guides need to be powered by different motors to meet the different air resistance requirements of different parts of the first vehicle. This results in different lifting frequencies, lifting directions, or lifting heights of the first and second air guides, in order to meet the air resistance requirements of different parts of the first vehicle in different scenarios.
[0043] Optionally, the guide plates in the first and second guide members can be flat plates or curved plates, and this embodiment does not limit them.
[0044] In one possible implementation, the distance between the driving part of the first driving member and the center point of the first lifting rod is less than a fourth threshold, and / or the distance between the driving part of the second driving member and the center point of the second lifting rod is less than a fifth threshold.
[0045] In this embodiment, the driving part of the first driving member should be as close as possible to the center point of the first lifting rod, such that the distance between the driving part of the first driving member and the center point of the first lifting rod is less than a fourth threshold. Thus, when the first driving member drives the first lifting rod to rise or fall, the force exerted on the first lifting rod by the driving part of the first driving member can be balanced, more effectively driving the first guide member to rise or fall. Similarly, the driving part of the second driving member should be as close as possible to the center point of the second lifting rod, such that the distance between the driving part of the second driving member and the center point of the second lifting rod is less than a fifth threshold. Thus, when the second driving member drives the second lifting rod to rise or fall, the force exerted on the second lifting rod by the driving part of the second driving member can be balanced, more effectively driving the second guide member to rise or fall.
[0046] Optionally, the fourth and fifth thresholds are not fixed values and can be adjusted according to different scenarios to improve the force-bearing performance of the drive unit on the lifting rod. This embodiment does not limit this.
[0047] In one possible implementation, when the first vehicle is parked, or when the first vehicle's speed is less than a sixth threshold, or when the slope of the road surface where the first vehicle is located is greater than a seventh threshold, at least one driving member is used to drive at least one moving member to move, thereby moving the first guide member to a first position and moving the two second guide members to a second position. Wherein, the height of the first guide member relative to at least one moving member in the first position is greater than an eighth threshold, and / or, the height of the second guide members relative to at least one moving member in the second position is greater than a ninth threshold.
[0048] In this embodiment, when the first vehicle is parked, traveling at low speed, or on a road with a large slope, the first guide vane can be adjusted to a first position and the second guide vane to a second position to ensure sufficient ground clearance for both the first and second guide vanes in the first and second positions. This prevents the guide vanes from scraping against the ground, thereby meeting the driving requirements in the above scenarios and improving the safety and reliability of the vehicle.
[0049] In one possible implementation, when the speed of the first vehicle exceeds a tenth threshold, at least one drive member is used to drive at least one moving member to move, thereby moving the first guide member to a third position and moving the two second guide members to a fourth position. The wind resistance of the first guide member in the third position is less than the wind resistance of the second guide members in the fourth position.
[0050] In this embodiment, when the first vehicle is traveling at high speed, the first guide vane can be adjusted to the third position and the second guide vane can be adjusted to the fourth position. This makes the wind resistance of the first guide vane at the third position less than the wind resistance of the second guide vane at the fourth position, thereby reducing the air resistance of the first vehicle in the above scenario. This can meet the driving requirements in the above scenario, reduce the vehicle's energy consumption, and improve the vehicle's range.
[0051] In one possible implementation, when the first vehicle's speed exceeds an eleventh threshold and it is under braking, at least one drive member drives at least one moving member to move, thereby moving the first guide member to a fifth position and moving the two second guide members to a sixth position. The wind resistance of the first guide member at the fifth position is greater than the wind resistance of the second guide members at the sixth position.
[0052] In this embodiment, when the first vehicle is traveling at high speed and braking, the first guide vane can be adjusted to the fifth position and the second guide vane can be adjusted to the sixth position. This makes the wind resistance of the first guide vane at the fifth position greater than the wind resistance of the second guide vane at the sixth position, thereby increasing the air resistance and downforce of the first vehicle in the above scenario. This can meet the driving requirements in the above scenario, help the vehicle maintain vehicle stability and brake quickly when braking at high speed, and improve the braking performance and safety of the vehicle.
[0053] Secondly, embodiments of this application provide a control method applied to a flow guiding device of a first vehicle. The flow guiding device includes at least one moving member, at least one driving member, a first flow guiding member, and two second flow guiding members. The first flow guiding member and the two second flow guiding members are respectively fixedly connected to the at least one moving member. The first flow guiding member is located between the two second flow guiding members, and the two second flow guiding members are respectively located in front of the left wheel and the right wheel of the first vehicle. The driving part of the at least one driving member is connected to the at least one moving member.
[0054] Specifically, the control method includes: acquiring first information and generating a control signal based on the first information. The first information includes vehicle information of a first vehicle and / or environmental information of the first vehicle. The control signal is used to control at least one driving member to drive at least one moving member to move a first guide member to a first position posture, and / or the control signal is used to control at least one driving member to drive at least one moving member to move two second guide members to a second position posture.
[0055] In this embodiment of the application, a control method is provided. Since the guide components in the guide device are arranged in a segmented design, with two second guide components located in front of the left and right wheels of the first vehicle, and the first guide component located between the two second guide components, different control signals can be generated based on the vehicle information of the first vehicle and / or the environmental information of the first vehicle. These signals are used to control and adjust the position and attitude of the first guide component to a first position and / or to control the second guide component to a second position and attitude, so as to optimize the air resistance of the first vehicle in different scenarios and thus meet the driving needs in different scenarios.
[0056] Optionally, the meaning of the position and attitude of the first and second guide components can differ under different control and adjustment schemes. For example, in an adjustment scheme where the moving component in the guide device is a rotating shaft, the control signal is used to control the rotation of the first and second guide components to adjust their position and attitude. In this case, the position and attitude may include the angle of rotation of the guide components. As another example, in an adjustment scheme where the moving component in the guide device is a lifting rod, the control signal is used to control the raising and lowering of the first and second guide components to adjust their position and attitude. In this case, the position and attitude may include the height of the raising and lowering of the guide components.
[0057] In one possible implementation, the at least one moving component includes a rotating shaft, and a control signal is used to control at least one driving component to drive the rotating shaft to rotate, thereby driving the first guide component and two second guide components to rotate.
[0058] In this embodiment, at least one moving component includes a rotating shaft. A control signal is used to control at least one driving component to drive the rotating shaft to rotate, thereby rotating the first guide vane and two second guide vanes to adjust their positions and orientations. This ensures that the positions and orientations of the first guide vane and / or the second guide vanes differ depending on the vehicle's location in different scenarios. Through this embodiment, the rotation of the first and second guide vanes can be controlled by a control signal to adjust their positions and orientations, optimizing the vehicle's air resistance in different scenarios and meeting driving requirements in various situations.
[0059] In one possible implementation, the at least one moving member includes a first moving member and a second moving member, and the at least one driving member includes a first driving member and a second driving member. A control signal is used to control the first driving member to drive the first moving member to move, thereby driving the first guide member to move. The control signal is also used to control the second driving member to drive the second moving member to move, thereby driving the two second guide members to move.
[0060] In this embodiment, at least one moving component includes a first moving component and a second moving component, and at least one driving component includes a first driving component and a second driving component. The first driving component can be controlled by a control signal to drive the first moving component, thereby moving the first guide component and adjusting its position and attitude. Similarly, the second driving component can be controlled by a control signal to drive the second moving component, thereby moving the second guide component and adjusting its position and attitude. This ensures that the position and attitude of the first guide component and / or the second guide component differ depending on the vehicle's location in different scenarios. Through this embodiment, two driving components can be controlled by control signals to drive two moving components, thereby adjusting the position and attitude of the first and second guide components respectively, to optimize the air resistance of the first vehicle in different scenarios and meet the driving requirements of various scenarios.
[0061] Optionally, the first driving element and the second driving element can be connected to the same motor, and a control signal is used to control the output power of the same motor, so that the first driving element and the second driving element drive the first moving element and the second moving element respectively, thereby driving the first guide element and the two second guide elements to move. At this time, the first guide element and the two second guide elements will move in the same direction with the same offset at the same frequency.
[0062] Optionally, the first driving element and the second driving element can be connected to different first and second motors, respectively. A control signal is used to control the output power of the first motor, causing the first driving element to drive the first moving element to move, thereby moving the first guide element. The control signal is also used to control the output power of the second motor, causing the second driving element to drive the second moving element to move, thereby moving the two second guide elements. In this case, the movement frequency, direction, and offset of the first guide element and the two second guide elements may be the same or different.
[0063] In one possible implementation, the first moving member includes a first rotating shaft, and the second moving member includes a second rotating shaft. A control signal is used to control the first driving member to drive the first rotating shaft to rotate, thereby causing the first guide member to rotate. The control signal is also used to control the second driving member to drive the second rotating shaft to rotate, thereby causing the two second guide members to rotate.
[0064] In this embodiment, the first moving component includes a first rotating shaft, and the second moving component includes a second rotating shaft. A control signal can be used to control a first driving component to rotate the first rotating shaft, thereby rotating the first guide component and adjusting its position and attitude. Alternatively, a control signal can be used to control a second driving component to rotate the second rotating shaft, thereby rotating the second guide component and adjusting its position and attitude. This ensures that the position and attitude of the first guide component and / or the second guide component differ depending on the vehicle's operating conditions. Through this embodiment, control signals can be used to control two driving components to drive two rotating shafts, thereby adjusting the position and attitude of the first and second guide components respectively, optimizing the vehicle's air resistance in different scenarios, and meeting driving requirements in various situations.
[0065] In one possible implementation, the first moving member includes a first lifting rod, and the second moving member includes a second lifting rod. A control signal is used to control a first driving member to drive the first lifting rod to rise and fall, thereby causing the first guide member to rise and fall. The control signal is also used to control a second driving member to drive the second lifting rod to rise and fall, thereby causing the two second guide members to rise and fall.
[0066] In this embodiment, the first moving component includes a first lifting rod, and the second moving component includes a second lifting rod. A control signal can control a first driving component to drive the first lifting rod to rise and fall, thereby raising and lowering the first guide vane to adjust its position and attitude. Alternatively, a control signal can control a second driving component to drive the second lifting rod to rise and fall, thereby raising and lowering the second guide vane to adjust its position and attitude. This ensures that the position and attitude of the first guide vane and / or the second guide vane differ depending on the vehicle's location in different scenarios. Through this embodiment, control signals can be used to control two driving components to drive two lifting rods, respectively adjusting the position and attitude of the first and second guide vanes to optimize the vehicle's air resistance in different scenarios and meet driving requirements in various situations.
[0067] In one possible implementation, the generation of the control signal based on the first information can be achieved in ways including but not limited to: based on the first information, determining that the first vehicle is in a parked state, or the first vehicle's speed is less than a sixth threshold, or the slope of the road surface where the first vehicle is located is greater than a seventh threshold, generating the first control signal. The first control signal is used to control at least one driving member to drive at least one moving member to move, thereby moving the first guide member to a first position and moving two second guide members to a second position. Wherein, the height of the first guide member relative to at least one moving member in the first position is greater than an eighth threshold, and / or, the height of the second guide member relative to at least one moving member in the second position is greater than a ninth threshold.
[0068] In this embodiment, when the first vehicle is parked, traveling at low speed, or on a road with a large slope, the first control signal can be used to adjust the first guide to a first position and the second guide to a second position, so that the ground clearance of the first guide in the first position is sufficient, and / or the ground clearance of the second guide in the second position is sufficient, to prevent the guide from scraping against the ground, thereby meeting the driving requirements in the above scenarios and improving the safety and reliability of the vehicle.
[0069] In one possible implementation, the above-mentioned generation of a control signal based on the first information can be achieved in ways including but not limited to: based on the first information, determining that the speed of the first vehicle is greater than a tenth threshold, generating a second control signal, the second control signal being used to control at least one driving component to drive at least one moving component to move, thereby moving the first guide component to a third position and moving the two second guide components to a fourth position. Wherein, the wind resistance corresponding to the first guide component in the third position is less than the wind resistance corresponding to the second guide components in the fourth position.
[0070] In this embodiment, when the first vehicle is traveling at high speed, the first guide vane can be adjusted to the third position and the second guide vane can be adjusted to the fourth position by the second control signal. This makes the wind resistance of the first guide vane at the third position less than the wind resistance of the second guide vane at the fourth position, thereby reducing the air resistance of the first vehicle in the above scenario. This can meet the driving requirements in the above scenario, reduce the energy consumption of the vehicle, and improve the vehicle's range.
[0071] In one possible implementation, the generation of the control signal based on the first information can be achieved in ways including but not limited to: based on the first information, determining that the first vehicle's speed is greater than an eleventh threshold and it is in a braking state, generating a third control signal. This third control signal controls at least one driving component to drive at least one moving component to move, thereby moving the first guide component to a fifth position and moving the two second guide components to a sixth position. The wind resistance of the first guide component at the fifth position is greater than the wind resistance of the second guide components at the sixth position.
[0072] In this embodiment, when the first vehicle is traveling at high speed and braking, the first guide vane can be adjusted to the fifth position and the second guide vane can be adjusted to the sixth position by the third control signal. This makes the wind resistance of the first guide vane at the fifth position greater than the wind resistance of the second guide vane at the sixth position, thereby increasing the air resistance and downforce of the first vehicle in the above scenario. This can meet the driving requirements in the above scenario, help the vehicle maintain vehicle stability and brake quickly when braking at high speed, and improve the braking performance and safety of the vehicle.

[0112] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described below with reference to the accompanying drawings.
[0113] The terms "first" and "second," etc., used in the specification, claims, and drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.
[0114] The term "embodiment" as used herein means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that, unless otherwise specified or logically conflicting, the terminology and / or descriptions between the various embodiments of this application are consistent and can be mutually referenced, and technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.
[0115] It should be understood that in this application, "at least one (item)" means one or more, "more than one" means two or more, "at least two (items)" means two or three or more, and "and / or" is used to describe the relationship between related objects, indicating that there can be three relationships. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist simultaneously, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one (item) of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one (item) of a, b, or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, and c can be single or multiple.
[0116] It should be noted that, in this application, "instruction" can include direct instruction, indirect instruction, explicit instruction, and implicit instruction. When describing a certain instruction information for the purpose of instructing A, it can be understood that the instruction information carries A, directly instructs A, or indirectly instructs A.
[0117] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementations, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a correlation between the other information and the information to be instructed. It can also indicate only a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various information, thereby reducing instruction overhead to some extent. The information to be instructed can be sent as a whole or divided into multiple sub-information units, and the sending period and / or timing of these sub-information units can be the same or different. This application does not limit the specific sending method. The sending period and / or timing of these sub-information units can be predefined, for example, according to a protocol, or configured by the transmitting device by sending configuration information to the receiving device.
[0118] It should be noted that in this application, "send" can be understood as "output" and "receive" can be understood as "input". "Send information to A", where "to A" simply indicates the direction of information transmission, and A is the destination, does not limit "send information to A" to a direct transmission over the air interface. "Send information to A" includes sending information directly to A, as well as sending information indirectly to A through a transmitter. Therefore, "send information to A" can also be understood as "outputting information destined for A". Similarly, "receive information from A" indicates that the source of the information is A, including receiving information directly from A, as well as receiving information indirectly from A through a receiver. Therefore, "receive information from A" can also be understood as "inputting information from A".
[0119] This application provides a flow guiding device, a control method, and related products, relating to the field of vehicle technology, such as a flow guiding device installed at a specific location on a vehicle body, and a corresponding control method for the flow guiding device. To more clearly describe the solution of this application, some terms used in the embodiments of this application will be explained below.
[0120] Airflow deflectors are functional components installed at specific locations on a vehicle body (such as the front, bottom, sides, and rear) to reduce wind resistance, improve driving stability, or improve the flow field around the vehicle body by optimizing airflow direction. Their core function is to guide airflow to meet the vehicle's driving needs.
[0121] Please see Figure 1 , Figure 1 This is a schematic diagram of a front-side airflow guide device provided in an embodiment of this application.
[0122] like Figure 1 As shown, commonly used air deflectors are generally fixedly installed below the front bumper of the vehicle (also known as front bumper air deflectors), running through the entire front bumper on both sides.
[0123] However, due to the addition of a battery pack and a bottom protection plate, electric vehicles generally have a relatively flat bottom. With the widespread use of flat bottom protection plates in electric vehicles, traditional airflow devices cannot meet the driving needs in new scenarios.
[0124] Therefore, a feasible solution is urgently needed to meet the optimization requirements of air resistance when vehicles are in motion under different scenarios.
[0125] In view of this, this application provides a flow guiding device and proposes a new control method and related products based on the flow guiding device, which relates to the field of vehicle technology, such as a flow guiding device installed at a specific position on the vehicle body, and a control method corresponding to the flow guiding device, which can meet the optimization requirements of air resistance of vehicles in different scenarios.
[0126] The embodiments provided in this application will now be described in detail with reference to the accompanying drawings.
[0127] Please see Figure 2 , Figure 2 This is a schematic diagram of a flow guiding device provided in an embodiment of this application. This flow guiding device is applied in the field of vehicle technology, such as a flow guiding device installed at a specific location on a vehicle body.
[0128] Specifically, the flow guiding device is applied to the first vehicle, and the flow guiding device includes, but is not limited to:
[0129] A first flow guide 201 and two second flow guides 202, at least one moving part 203, and at least one driving part 204.
[0130] The first guide member 201 and two second guide members 202 are fixedly connected to at least one moving member 203. The first guide member 201 is located between the two second guide members 202. The two second guide members 202 are located in front of the left wheel and the right wheel of the first vehicle, respectively. The driving part of at least one driving member 204 is connected to at least one moving member 203.
[0131] At least one drive member 204 is used to drive at least one motion member 203 to move to move the first guide member 201 to a first position posture, and / or at least one drive member 204 is used to drive at least one motion member 203 to move to move the two second guide members 202 to a second position posture.
[0132] Optionally, the two second guide members 202 may be located in front of the left front wheel and the right front wheel of the first vehicle, or in front of the left rear wheel and the right rear wheel of the first vehicle, respectively. This application embodiment does not limit this.
[0133] Optionally, the length of the second guide 202 is related to the width of the left and right wheels of the first vehicle, and can be determined according to the model of the first vehicle.
[0134] Optionally, the first guide member 201 may be located in the area between the left front wheel and the right front wheel of the first vehicle, or it may be located in the area between the left rear wheel and the right rear wheel of the first vehicle. This application embodiment does not limit this.
[0135] Optionally, the length of the first guide member 201 is related to the distance between the left and right wheels of the first vehicle, and can be determined according to the model of the first vehicle.
[0136] Optionally, the first vehicle being in different scenarios can be understood as the first vehicle being in different states or different environments. This application embodiment does not limit this.
[0137] Optionally, under different adjustment schemes, the position and attitude of the first guide member 201 and the second guide member 202 may have different meanings.
[0138] For example, in the adjustment scheme where the moving part 203 is a rotating shaft, the first guide 201 and the two second guides 202 are rotated by rotating the shaft to adjust the position and attitude of the first guide 201 and the second guide 202. At this time, the position and attitude can include the angle of rotation of the guide.
[0139] For example, in the adjustment scheme where the moving part 203 is a lifting rod, the lifting rod drives the first guide 201 and the two second guides 202 to rise and fall, so as to adjust the position and attitude of the first guide 201 and the second guide 202. At this time, the position and attitude can include the height of the guide lifting.
[0140] Optionally, at least one driving component 204 may include, but is not limited to, driving components such as driving gears and driving chains, and the embodiments of this application do not impose such limitations.
[0141] It is understood that the airflow guiding components in the airflow guiding device of this application embodiment are designed and arranged in segments according to the positions of the left and right wheels of the first vehicle. The two second airflow guiding components 202 in the airflow guiding device are respectively located in front of the left and right wheels of the first vehicle, and the first airflow guiding component 201 is located between the two second airflow guiding components 202. Therefore, to meet the differences in air resistance requirements of the first vehicle in different scenarios, and the differences in air resistance requirements of different parts of the first vehicle, the position and attitude of the first airflow guiding component 201 and / or the position and attitude of the second airflow guiding component 202 can be adjusted to meet the aforementioned differences in air resistance requirements.
[0142] Through the embodiments of this application, the air resistance of the first vehicle can be optimized in different scenarios by adjusting the position and attitude of the first guide 201 and / or the position and attitude of the second guide 202, thereby meeting the driving needs in different scenarios.
[0143] In one possible embodiment, the flow guiding component, driving component, and moving component in the above-mentioned flow guiding device may have different implementation methods. The possible implementation schemes will be described below.
[0144] Option 1:
[0145] The aforementioned at least one moving component 203 includes a rotating shaft, and at least one driving component 204 is used to drive the rotating shaft to rotate, thereby driving the first guide component 201 and the two second guide components 202 to rotate.
[0146] Optionally, since the first guide element and the two second guide elements are fixedly connected to the same rotating shaft, the first guide element and the two second guide elements will rotate at the same frequency in the same direction and at the same angle under the drive of the rotation of the shaft.
[0147] It is understood that at least one moving part includes a rotating shaft, which can be driven to rotate by at least one driving member, thereby causing the first guide and two second guides to rotate, so as to adjust the position and attitude of the first guide and the second guide, so that the position and attitude of the first guide are different in different scenarios of the first vehicle, and / or the position and attitude of the second guide are different.
[0148] Through the embodiments of this application, the position and attitude of the first guide member and the second guide member can be rotated and adjusted to optimize the air resistance of the first vehicle in different scenarios and meet the driving needs in different scenarios.
[0149] Alternatively, for details regarding Option 1 above, please refer to [link / reference]. Figure 2As shown, the first guide member 201 includes a first guide plate 2011 and a second guide plate 2012 fixedly connected at a first included angle, and the second guide member 202 includes a third guide plate 2021 and a fourth guide plate 2022 fixedly connected at a second included angle.
[0150] The angle bisector of the first included angle forms a third included angle with the angle bisector of the second included angle.
[0151] It is understood that the first flow guide includes two flow guide plates, which are fixedly connected at a first included angle. The second flow guide includes two flow guide plates, which are fixedly connected at a second included angle. Furthermore, the angle bisector of the first included angle and the angle bisector of the second included angle form a third included angle. This can be understood as the two flow guide plates in the first flow guide and the two flow guide plates in the second flow guide having a third included angle from the side view perspective of the flow guiding device, i.e., they do not completely coincide.
[0152] Optionally, since the two guide plates in the first guide member and the two guide plates in the second guide member have a third included angle in the side view of the guide device, and the first guide member and the second guide member are both fixedly connected to the same rotating shaft, under the drive of the rotation of the rotating shaft, no matter how the first guide member and the second guide member rotate, the two guide plates in the first guide member and the two guide plates in the second guide member will maintain the third included angle in the side view of the guide device.
[0153] Optionally, the guide plates in the first and second guide members can be flat plates or curved plates, and the embodiments of this application do not limit this.
[0154] Optionally, when the guide plate in the first guide member is a curved plate, each of the two guide plates in the first guide member has a plane that is tangent to the curved surface at one end of the fixed connection shaft. The included angle between the two tangent planes can be regarded as the first included angle between the two guide plates in the first guide member.
[0155] Through the embodiments of this application, the structures of the first guide and the second guide can be designed differently to meet the different air resistance requirements of different parts of the first vehicle. Even if the first guide and the second guide are both fixedly connected to the same rotating shaft, based on the differentiated structure of the first guide and the second guide, the position and attitude of the first guide and the second guide can be adjusted by rotation to meet the air resistance requirements of different parts of the first vehicle in different scenarios, thereby meeting the driving needs in different scenarios.
[0156] Optionally, in the above scheme one, the first included angle, the second included angle, and the third included angle are equal.
[0157] Optionally, the first included angle, the second included angle, and the third included angle are all 90°. In this case, the two guide vanes in the first guide member are L-shaped, and the two guide vanes in the second guide member are L-shaped.
[0158] Alternatively, for details regarding Option 1 above, please refer to [link / reference]. Figure 2 As shown, the projections of the first guide vane 2011 and the second guide vane 2012 on the reference plane are offset from each other, and the projections of the third guide vane 2021 and the fourth guide vane 2022 on the reference plane are also offset from each other. The projections of the first guide vane 2011 and the third guide vane 2021 on the reference plane coincide with each other, while the projections of the second guide vane 2012 and the fourth guide vane 2022 on the reference plane are located on both sides of the rotating shaft.
[0159] The reference plane is the plane perpendicular to the axis of rotation.
[0160] It is understandable that the projections of the first guide plate in the first guide member and the third guide plate in the second guide member on the reference plane coincide with each other, and the projections of the second guide plate in the first guide member and the fourth guide plate in the second guide member on the reference plane are located on both sides of the rotating shaft.
[0161] Through the embodiments of this application, the structures of the first guide and the second guide can be designed differently to meet the different air resistance requirements of different parts of the first vehicle. Even if the first guide and the second guide are both fixedly connected to the same rotating shaft, based on the differentiated structure of the first guide and the second guide, the position and attitude of the first guide and the second guide can be adjusted by rotation to meet the air resistance requirements of different parts of the first vehicle in different scenarios, thereby meeting the driving needs in different scenarios.
[0162] Optionally, in the above-described scheme one, the distance between the driving part of at least one driving member 204 and the center point of the rotating shaft is less than a first threshold.
[0163] Optionally, the first threshold is not a fixed value and can be adjusted according to different scenarios to improve the force-bearing performance of the driving part of at least one driving member on the rotating shaft. This application embodiment does not limit this.
[0164] In this embodiment, the driving portion of at least one driving member should be as close as possible to the center point of the rotating shaft, such that the distance between the driving portion of at least one driving member and the center point of the rotating shaft is less than a first threshold. Thus, when at least one driving member drives the rotating shaft to rotate, the force exerted on the rotating shaft by the driving portion of at least one driving member can be balanced, more effectively driving the first guide member and the two second guide members to rotate.
[0165] Option 2:
[0166] For details, please refer to [link / reference]. Figure 3 , Figure 3This is a schematic diagram of another flow guiding device provided in an embodiment of this application.
[0167] like Figure 3 As shown, the at least one moving component 203 includes a first moving component 2031 and a second moving component 2032, and the at least one driving component 204 includes a first driving component 2041 and a second driving component 2042. The first driving component 2041 drives the first moving component 2031 to move, thereby driving the first guide component 201 to move. The second driving component 2042 drives the second moving component 2032 to move, thereby driving the two second guide components 202 to move.
[0168] Optionally, the first driving member and the second driving member can be connected to the same motor. Under the power output of the same motor, the first driving member and the second driving member drive the first moving member and the second moving member respectively, so as to drive the first guide member and the two second guide members to move. At this time, the first guide member and the two second guide members will move in the same direction with the same offset at the same frequency.
[0169] Optionally, the first driving component and the second driving component can be connected to different first and second motors, respectively. Under the power output by the first motor, the first driving component drives the first moving component to move, thereby driving the first guide component to move. Under the power output by the second motor, the second driving component drives the second moving component to move, thereby driving the two second guide components to move. At this time, the movement frequency, movement direction, and movement offset of the first guide component and the two second guide components may be the same or different.
[0170] It is understood that in the embodiments of this application, at least one moving component includes a first moving component and a second moving component, and at least one driving component includes a first driving component and a second driving component. The first moving component can be driven to move by the first driving component, thereby driving the first guide component to move, so as to adjust the position and attitude of the first guide component. Alternatively, the second moving component can be driven to move by the second driving component, thereby driving the second guide component to move, so as to adjust the position and attitude of the second guide component. This results in the first guide component having a different position and attitude under different scenarios, and / or the second guide component having a different position and attitude.
[0171] Through the embodiments of this application, two moving parts can be driven by two driving parts to adjust the position and attitude of the first guide and the second guide respectively, so as to optimize the air resistance of the first vehicle in different scenarios and meet the driving needs in different scenarios.
[0172] Alternatively, for details regarding Option 2 above, please refer to [link / reference]. Figure 3As shown, the first moving component 2031 includes a first rotating shaft, and the second moving component 2032 includes a second rotating shaft. The first driving component 2041 is used to drive the first rotating shaft to rotate, thereby driving the first guide component 201 to rotate. The second driving component 2041 is used to drive the second rotating shaft to rotate, thereby driving the two second guide components 202 to rotate.
[0173] It is understood that in the embodiments of this application, the first moving component includes a first rotating shaft, and the second moving component includes a second rotating shaft. The first rotating shaft can be driven to rotate by the first driving component, thereby driving the first guide component to rotate and adjusting the position and attitude of the first guide component. Alternatively, the second rotating shaft can be driven to rotate by the second driving component, thereby driving the second guide component to rotate and adjusting the position and attitude of the second guide component. This results in the first guide component having a different position and attitude in different scenarios, and / or the second guide component having a different position and attitude.
[0174] Through the embodiments of this application, two rotating shafts can be driven by two driving components to adjust the position and attitude of the first guide and the second guide respectively, so as to optimize the air resistance of the first vehicle under different scenarios and meet the driving needs under different scenarios.
[0175] Alternatively, for details regarding Option 2 above, please refer to [link / reference]. Figure 3 As shown, the first guide member 201 includes a fifth guide plate, and the second guide member 202 includes a sixth guide plate.
[0176] It is understandable that the first flow guide includes a single flow deflector, and the second flow guide includes a single flow deflector.
[0177] Optionally, since both the first and second air guides include a single air deflector, the first and second air guides need to be powered by different motors to meet the different air resistance requirements of different parts of the first vehicle. This results in different rotation frequencies, directions, or angles of the first and second air guides, in order to meet the air resistance requirements of different parts of the first vehicle in different scenarios.
[0178] Optionally, the guide plates in the first and second guide members can be flat plates or curved plates, and this embodiment does not limit them.
[0179] Through the embodiments of this application, since the first guide and the second guide are fixedly connected to different rotating shafts, the positions and attitudes of the first guide and the second guide can be adjusted by rotation to meet the air resistance requirements of different parts of the first vehicle in different scenarios, thereby meeting the driving needs in different scenarios.
[0180] Alternatively, for details regarding Option 2 above, please refer to [link / reference]. Figure 3As shown, the distance between the driving part of the first driving member 2041 and the center point of the first rotating shaft is less than a second threshold, and / or the distance between the driving part of the second driving member 2042 and the center point of the second rotating shaft is less than a third threshold.
[0181] Optionally, the second threshold and the third threshold are not fixed values and can be adjusted according to different scenarios to improve the force-bearing performance of the drive part of the drive component on the rotating shaft. This application embodiment does not limit this.
[0182] In this embodiment, the driving part of the first driving member should be as close as possible to the center point of the first rotating shaft, such that the distance between the driving part of the first driving member and the center point of the first rotating shaft is less than a second threshold. In this way, when the first driving member drives the first rotating shaft to rotate, the force exerted by the driving part of the first driving member on the first rotating shaft can be balanced, thus more effectively driving the first guide member to rotate. Similarly, the driving part of the second driving member should be as close as possible to the center point of the second rotating shaft, such that the distance between the driving part of the second driving member and the center point of the second rotating shaft is less than a third threshold. In this way, when the second driving member drives the second rotating shaft to rotate, the force exerted by the driving part of the second driving member on the second rotating shaft can be balanced, thus more effectively driving the second guide member to rotate.
[0183] Option 3:
[0184] For details, please refer to [link / reference]. Figure 4 , Figure 4 This is a schematic diagram of another flow guiding device provided in an embodiment of this application.
[0185] like Figure 4 As shown, the at least one moving component 203 includes a first moving component 2033 and a second moving component 2034, and the at least one driving component 204 includes a first driving component 2043 and a second driving component 2044. The first driving component 2043 drives the first moving component 2033 to move, thereby driving the first guide component 201 to move. The second driving component 2044 drives the second moving component 2034 to move, thereby driving the two second guide components 202 to move.
[0186] Optionally, the first driving member and the second driving member can be connected to the same motor. Under the power output of the same motor, the first driving member and the second driving member drive the first moving member and the second moving member respectively, so as to drive the first guide member and the two second guide members to move. At this time, the first guide member and the two second guide members will move in the same direction with the same offset at the same frequency.
[0187] Optionally, the first driving component and the second driving component can be connected to different first and second motors, respectively. Under the power output by the first motor, the first driving component drives the first moving component to move, thereby driving the first guide component to move. Under the power output by the second motor, the second driving component drives the second moving component to move, thereby driving the two second guide components to move. At this time, the movement frequency, movement direction, and movement offset of the first guide component and the two second guide components may be the same or different.
[0188] It is understood that in the embodiments of this application, at least one moving component includes a first moving component and a second moving component, and at least one driving component includes a first driving component and a second driving component. The first moving component can be driven to move by the first driving component, thereby driving the first guide component to move, so as to adjust the position and attitude of the first guide component. Alternatively, the second moving component can be driven to move by the second driving component, thereby driving the second guide component to move, so as to adjust the position and attitude of the second guide component. This results in the first guide component having a different position and attitude under different scenarios, and / or the second guide component having a different position and attitude.
[0189] Through the embodiments of this application, two moving parts can be driven by two driving parts to adjust the position and attitude of the first guide and the second guide respectively, so as to optimize the air resistance of the first vehicle in different scenarios and meet the driving needs in different scenarios.
[0190] Alternatively, for details regarding Option 3 above, please refer to [link / reference]. Figure 4 As shown, the first moving component 2033 includes a first lifting rod, and the second moving component 2034 includes a second lifting rod. The first driving component 2043 is used to drive the first lifting rod to rise and fall, thereby driving the first guide component 201 to rise and fall. The second driving component 2044 is used to drive the second lifting rod to rise and fall, thereby driving the two second guide components 202 to rise and fall.
[0191] It is understood that in the embodiments of this application, the first moving component includes a first lifting rod, and the second moving component includes a second lifting rod. The first lifting rod can be driven to rise and fall by the first driving component, thereby driving the first guide component to rise and fall to adjust the position and attitude of the first guide component. Alternatively, the second lifting rod can be driven to rise and fall by the second driving component, thereby driving the second guide component to rise and fall to adjust the position and attitude of the second guide component. This results in the first guide component having a different position and attitude under different scenarios, and / or the second guide component having a different position and attitude.
[0192] Through the embodiments of this application, two lifting rods can be driven by two driving components to adjust the position and attitude of the first guide and the second guide respectively, so as to optimize the air resistance of the first vehicle in different scenarios and meet the driving needs of different scenarios.
[0193] Alternatively, for details regarding Option 3 above, please refer to [link / reference]. Figure 4As shown, the first guide member 201 includes a seventh guide plate, and the second guide member 202 includes an eighth guide plate.
[0194] It is understandable that the first flow guide includes a single flow deflector, and the second flow guide includes a single flow deflector.
[0195] Optionally, since both the first and second air guides include a single air deflector, the first and second air guides need to be powered by different motors to meet the different air resistance requirements of different parts of the first vehicle. This results in different lifting frequencies, lifting directions, or lifting heights of the first and second air guides, in order to meet the air resistance requirements of different parts of the first vehicle in different scenarios.
[0196] Optionally, the guide plates in the first and second guide members can be flat plates or curved plates, and this embodiment does not limit them.
[0197] Through the embodiments of this application, since the first guide and the second guide are fixedly connected to different lifting rods, the positions and attitudes of the first guide and the second guide can be adjusted by lifting to meet the air resistance requirements of different parts of the first vehicle in different scenarios, thereby meeting the driving needs in different scenarios.
[0198] Alternatively, for details regarding Option 3 above, please refer to [link / reference]. Figure 4 As shown, the distance between the driving part of the first driving member 2043 and the center point of the first lifting rod is less than a fourth threshold, and / or the distance between the driving part of the second driving member 2044 and the center point of the second lifting rod is less than a fifth threshold.
[0199] Optionally, the fourth and fifth thresholds are not fixed values and can be adjusted according to different scenarios to improve the force-bearing performance of the drive unit on the lifting rod. This application embodiment does not limit this.
[0200] In this embodiment, the driving part of the first driving member should be as close as possible to the center point of the first lifting rod, such that the distance between the driving part of the first driving member and the center point of the first lifting rod is less than a fourth threshold. In this way, when the first driving member drives the first lifting rod to rise or fall, the force exerted by the driving part of the first driving member on the first lifting rod can be balanced, thus more effectively driving the first guide member to rise or fall. Similarly, the driving part of the second driving member should be as close as possible to the center point of the second lifting rod, such that the distance between the driving part of the second driving member and the center point of the second lifting rod is less than a fifth threshold. In this way, when the second driving member drives the second lifting rod to rise or fall, the force exerted by the driving part of the second driving member on the second lifting rod can be balanced, thus more effectively driving the second guide member to rise or fall.
[0201] It should be understood that the above-described schemes one to three are merely examples illustrating different possible implementations of the guide components, drive components, and moving components in the above-described flow guiding device, and should not be construed as limiting the embodiments of this application.
[0202] It should be understood that any new embodiments obtained by reasonable modifications, additions, or combinations of the above-mentioned schemes one to three are all within the protection scope of the embodiments of this application.
[0203] In one possible embodiment, the at least one driving member 204 is used to drive at least one moving member 203 to move, thereby moving the first guide member 201 and the two second guide members 202, such that the position and orientation of the first guide member 201 are different, and / or the position and orientation of the second guide members 202 are different, depending on the first vehicle being in different scenarios. Different implementation scenarios may exist, and these scenarios will be described below.
[0204] Scene 1:
[0205] When the first vehicle is parked, or the speed of the first vehicle is less than the sixth threshold, or the slope of the road surface where the first vehicle is located is greater than the seventh threshold, at least one drive member 204 is used to drive at least one moving member 203 to move, so as to move the first guide member 201 to the first position and move the two second guide members 202 to the second position.
[0206] Wherein, the height of the first guide member 201 relative to at least one moving member 203 in the first position is greater than an eighth threshold, and / or, the height of the second guide member 202 relative to at least one moving member 203 in the second position is greater than a ninth threshold.
[0207] Optionally, the sixth, seventh, eighth, and ninth thresholds are not fixed values and can be adjusted according to different scenarios to improve the accuracy of the position and attitude of the first and second guide members. This application embodiment does not limit this.
[0208] It is understood that, through the embodiments of this application, in scenarios where the first vehicle is parked, traveling at low speed, or on a road with a large slope, the first guide member can be adjusted to a first position, and the second guide member can be adjusted to a second position, so that the ground clearance of the first guide member in the first position is sufficient, and / or the ground clearance of the second guide member in the second position is sufficient, thereby preventing the guide members from scraping against the ground, thus meeting the driving needs in the above scenarios and improving the safety and reliability of the vehicle.
[0209] Alternatively, please refer to the above for details. Figure 2 , with the above Figure 2 Taking the illustrated guide device as an example, in scenarios where the first vehicle is parked, traveling at low speed, or on a road with a large slope, by adjusting the guide plate 2012 in the first guide member 201 to be level with the ground, and adjusting the guide plate 2022 in the second guide member 202 to be level with the ground, the ground clearance of the first guide member 201 and / or the ground clearance of the second guide member 202 are sufficient, thus preventing the first guide member 201 and the second guide member 202 from scraping against the ground. This can meet the driving needs in the above scenarios and improve the safety and reliability of the vehicle.
[0210] Scene 2:
[0211] When the speed of the first vehicle exceeds the tenth threshold, at least one drive member 204 is used to drive at least one moving member 203 to move, thereby moving the first guide member 201 to the third position and moving the two second guide members 202 to the fourth position.
[0212] Among them, the wind resistance of the first guide member 201 in the third position is less than the wind resistance of the second guide member 202 in the fourth position.
[0213] Optionally, the tenth threshold is not a fixed value and can be adjusted according to different scenarios to improve the accuracy of the position and attitude of the first and second guide members. This application embodiment does not limit this.
[0214] It is understood that, through the embodiments of this application, in the scenario where the first vehicle is traveling at high speed, by adjusting the first guide member to the third position and the second guide member to the fourth position, the wind resistance corresponding to the first guide member in the third position is less than the wind resistance corresponding to the second guide member in the fourth position, thereby reducing the air resistance of the first vehicle in the above scenario, thus meeting the driving requirements in the above scenario, reducing the vehicle's energy consumption, and improving the vehicle's range.
[0215] Optional, see details Figure 5 , Figure 5 This is a schematic diagram of another flow guiding device provided in an embodiment of this application.
[0216] like Figure 5 As shown, it can be considered as described above. Figure 2 The diagram shows the structure of the flow guiding device after rotating 90° counterclockwise or 270° clockwise. Figure 5Taking the illustrated airflow guiding device as an example, in the scenario where the first vehicle is traveling at high speed, by adjusting the airflow guide plate 2011 in the first airflow guide 201 to be horizontal with the ground and adjusting the airflow guide plate 2022 in the second airflow guide 202 to be vertical with the ground, the wind resistance corresponding to the first airflow guide 201 is less than the wind resistance corresponding to the second airflow guide 202.
[0217] At this point, for the area between the left and right wheels of the first vehicle, since the deflector 2011 in the first guide member 201 is horizontal to the ground, the air resistance in this area under the above scenario can be reduced. For the area in front of the left and right wheels of the first vehicle, since the deflector 2022 in the second guide member 202 is perpendicular to the ground, the airflow passes through the deflector 2022 first and then through the wheels. Compared with the airflow passing directly through the wheels, the air resistance in the area in front of the wheels under the above scenario can be reduced.
[0218] Therefore, by adjusting the position and attitude of the first guide member 201 and the second guide member 202, the air resistance of the first vehicle in the above-mentioned scenario two can be reduced, thereby meeting the driving requirements in the above-mentioned scenario two, reducing the energy consumption of the vehicle, and improving the vehicle's range.
[0219] Scene 3:
[0220] When the speed of the first vehicle is greater than the eleventh threshold and it is in a braking state, at least one drive member 204 is used to drive at least one moving member 203 to move, so as to move the first guide member 201 to the fifth position and to move the two second guide members 202 to the sixth position.
[0221] Among them, the wind resistance of the first guide member 201 in the fifth position is greater than the wind resistance of the second guide member 202 in the sixth position.
[0222] Optionally, the eleventh threshold is not a fixed value and can be adjusted according to different scenarios to improve the accuracy of the position and attitude of the first and second guide members. This application embodiment does not limit this.
[0223] It is understood that, through the embodiments of this application, in the scenario where the first vehicle is traveling at high speed and braking, the first guide member can be adjusted to the fifth position and the second guide member can be adjusted to the sixth position, so that the wind resistance corresponding to the first guide member at the fifth position is greater than the wind resistance corresponding to the second guide member at the sixth position. This increases the air resistance and downforce of the first vehicle in the above scenario, thereby meeting the driving requirements in the above scenario, assisting the vehicle in maintaining vehicle stability and rapid braking when braking at high speed, and improving the braking performance and safety of the vehicle.
[0224] Optional, see details Figure 6 , Figure 6 This is a schematic diagram of another flow guiding device provided in an embodiment of this application.
[0225] like Figure 6 As shown, it can be considered as described above. Figure 5 The diagram shown illustrates the structure of the flow guiding device after it has been rotated 180°. Figure 6 Taking the illustrated airflow guiding device as an example, in the scenario where the first vehicle is traveling at high speed and braking, by adjusting the airflow guide plate 2012 in the first airflow guide 201 to be perpendicular to the ground and adjusting the airflow guide plate 2021 in the second airflow guide 202 to be horizontal to the ground, the wind resistance corresponding to the first airflow guide 201 is greater than the wind resistance corresponding to the second airflow guide 202.
[0226] At this point, for the area between the left and right wheels of the first vehicle, since the deflector 2012 in the first guide member 201 is perpendicular to the ground, the air resistance in this area under the above scenario can be increased. For the area in front of the left and right wheels of the first vehicle, since the deflector 2021 in the second guide member 202 is horizontal to the ground, the airflow passes directly over the wheels. Compared to the airflow passing through the deflector 2021 first and then over the wheels, this increases the air resistance in the area in front of the wheels under the above scenario.
[0227] Therefore, by adjusting the position and attitude of the first guide member 201 and the second guide member 202, the air resistance of the first vehicle in the above-mentioned scenario three can be increased, thereby meeting the driving requirements in the above-mentioned scenario three, assisting the vehicle to maintain vehicle stability and rapid braking when braking at high speed, and improving the vehicle's braking performance and safety.
[0228] It should be understood that the above scenarios one to three are merely examples illustrating the position and orientation of the guide element in the above-mentioned guide device, and should not be construed as limiting the embodiments of this application.
[0229] It should be understood that any new embodiments obtained by reasonable modification, supplementation or combination of the above-described scenarios one to three are all within the protection scope of the embodiments of this application.
[0230] Please see Figure 7 , Figure 7 This is a flowchart illustrating a control method provided in an embodiment of this application. This control method is applied in the field of vehicle technology, such as a control method for a flow guide device installed at a specific location on a vehicle body.
[0231] Optionally, the control method is applied to a deflector device of a first vehicle. The deflector device includes at least one moving component, at least one driving component, a first deflector component, and two second deflector components. The first deflector component and the two second deflector components are respectively fixedly connected to the at least one moving component. The first deflector component is located between the two second deflector components, and the two second deflector components are respectively located in front of the left and right wheels of the first vehicle. The driving part of the at least one driving component is connected to the at least one moving component. Optionally, the deflector device can be specifically described above. Figures 2 to 6 The schematic diagram of the flow guiding device shown is not repeated in the embodiments of this application.
[0232] Specifically, the control method includes, but is not limited to, the following steps:
[0233] S701: The control device acquires the first information.
[0234] S702: The control device generates a control signal based on the first information.
[0235] It is understood that the control device in the embodiments of this application can be a device equipped with a processor / chip that can execute computer execution instructions, or it can be a processor / chip that can execute computer execution instructions. Optionally, the control device can be an electronic device, or it can be a processor / chip within an electronic device. Optionally, the control device can specifically be a computing device in a vehicle, or a software tool and / or hardware module in a computing device that can be used for drive control. Exemplarily, the control device can be a controller in a vehicle, such as an advanced driving assistance system (ADAS) and / or an autonomous driving system (ADS), or a mobile data center (MDC) (or autonomous driving domain controller), domain controller (DC), electronic control unit (ECU), etc., wherein the DC, such as a motion domain controller (MDC) or a vehicle domain controller (VDC), is used to execute the control methods in the embodiments of this application, which can meet the driving needs of optimizing vehicle air resistance in different scenarios.
[0236] Optionally, the control device and control method in the embodiments of this application can be applied to, but are not limited to, vehicle systems. The vehicle equipped with the vehicle system is an intelligent driving vehicle and can be replaced by a terminal device. The terminal device can be, but is not limited to, vehicles such as commercial vehicles, passenger cars, trains, industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), robots, etc. The embodiments of this application do not specifically limit this.
[0237] The first information includes vehicle information of the first vehicle and / or environmental information of the first vehicle. The control signal is used to control at least one driving member to drive at least one moving member to move the first guide member to a first position posture, and / or the control signal is used to control at least one driving member to drive at least one moving member to move the two second guide members to a second position posture.
[0238] Optionally, the vehicle information of the first vehicle includes, but is not limited to, information such as the vehicle speed and acceleration of the first vehicle.
[0239] Optionally, the environmental information of the first vehicle includes, but is not limited to, information such as road slope and obstacles.
[0240] Optionally, under different control adjustment schemes, the position and attitude of the first and second guide members may have different meanings.
[0241] For example, in an adjustment scheme where the moving part in the flow guiding device is a rotating shaft, the control signal is used to control the rotation of the first flow guiding member and the second flow guiding member to adjust the position and attitude of the first flow guiding member and the second flow guiding member. At this time, the position and attitude may include the angle of rotation of the flow guiding member.
[0242] For example, in an adjustment scheme where the moving part in the flow guiding device is a lifting rod, the control signal is used to control the lifting of the first flow guiding member and the second flow guiding member to adjust the position and attitude of the first flow guiding member and the second flow guiding member. At this time, the position and attitude may include the height of the flow guiding member lifting.
[0243] It is understood that the airflow guiding components in the airflow guiding device of this application embodiment are designed and arranged in segments according to the positions of the left and right wheels of the first vehicle. The two second airflow guiding components in the airflow guiding device are respectively located in front of the left and right wheels of the first vehicle, and the first airflow guiding component is located between the two second airflow guiding components. Therefore, to address the differences in air resistance requirements of the first vehicle in different scenarios, as well as the differences in air resistance requirements of different parts of the first vehicle, the aforementioned differences in air resistance requirements can be met by adjusting the position and / or the position and orientation of the first airflow guiding component and / or the second airflow guiding component.
[0244] Through the embodiments of this application, based on the vehicle information of the first vehicle and / or the environmental information of the first vehicle, different control signals can be generated when the first vehicle is in different scenarios. These signals are used to control and adjust the position and attitude of the first guide vane and / or the position and attitude of the second guide vane to optimize the air resistance of the first vehicle in different scenarios, thereby meeting the driving needs in different scenarios.
[0245] In one possible embodiment, the at least one moving component mentioned above includes a rotating shaft, as detailed in Scheme 1 above, which will not be repeated here.
[0246] At this time, the control signal is used to control at least one drive component to drive the shaft to rotate, so as to drive the first guide component and two second guide components to rotate.
[0247] It is understood that at least one moving part includes a rotating shaft, and a control signal is used to control at least one driving member to drive the rotating shaft to rotate, thereby causing the first guide and two second guides to rotate, so as to adjust the position and attitude of the first guide and the second guide, so that the position and attitude of the first guide are different in different scenarios of the first vehicle, and / or the position and attitude of the second guide are different.
[0248] Through the embodiments of this application, the position and attitude of the first guide and the second guide can be adjusted by controlling the rotation with control signals to optimize the air resistance of the first vehicle in different scenarios and meet the driving needs in different scenarios.
[0249] In one possible embodiment, the at least one moving member includes a first moving member and a second moving member, and the at least one driving member includes a first driving member and a second driving member.
[0250] At this time, the control signal is used to control the first driving member to drive the first moving member to move, thereby driving the first guide member to move. The control signal is also used to control the second driving member to drive the second moving member to move, thereby driving the two second guide members to move.
[0251] Optionally, the first driving element and the second driving element can be connected to the same motor, and a control signal is used to control the output power of the same motor, so that the first driving element and the second driving element drive the first moving element and the second moving element respectively, thereby driving the first guide element and the two second guide elements to move. At this time, the first guide element and the two second guide elements will move in the same direction with the same offset at the same frequency.
[0252] Optionally, the first driving element and the second driving element can be connected to different first and second motors, respectively. A control signal is used to control the output power of the first motor, causing the first driving element to drive the first moving element to move, thereby moving the first guide element. The control signal is also used to control the output power of the second motor, causing the second driving element to drive the second moving element to move, thereby moving the two second guide elements. In this case, the movement frequency, direction, and offset of the first guide element and the two second guide elements may be the same or different.
[0253] It is understood that in the embodiments of this application, at least one moving component includes a first moving component and a second moving component, and at least one driving component includes a first driving component and a second driving component. The first driving component can be controlled by a control signal to drive the first moving component to move, thereby driving the first guide component to move, so as to adjust the position and attitude of the first guide component. Alternatively, the second driving component can be controlled by a control signal to drive the second moving component to move, thereby driving the second guide component to move, so as to adjust the position and attitude of the second guide component. This results in the first guide component having a different position and attitude under different scenarios, and / or the second guide component having a different position and attitude.
[0254] Through the embodiments of this application, two driving components can be controlled by control signals to drive two moving components, and the positions and attitudes of the first guide component and the second guide component can be adjusted respectively to optimize the air resistance of the first vehicle in different scenarios and meet the driving needs in different scenarios.
[0255] In one possible embodiment, the first moving component includes a first rotating shaft, and the second moving component includes a second rotating shaft. For details, please refer to Scheme 2 above, which will not be repeated here.
[0256] At this time, the control signal is used to control the first driving component to drive the first rotating shaft to rotate, thereby driving the first guide component to rotate. The control signal is also used to control the second driving component to drive the second rotating shaft to rotate, thereby driving the two second guide components to rotate.
[0257] It is understood that in the embodiments of this application, the first moving component includes a first rotating shaft, and the second moving component includes a second rotating shaft. The first driving component can be controlled by a control signal to drive the first rotating shaft to rotate, thereby driving the first guide component to rotate, so as to adjust the position and attitude of the first guide component. Alternatively, the second driving component can be controlled by a control signal to drive the second rotating shaft to rotate, thereby driving the second guide component to rotate, so as to adjust the position and attitude of the second guide component. This results in the first guide component having a different position and attitude under different scenarios, and / or the second guide component having a different position and attitude.
[0258] Through the embodiments of this application, two driving components can be controlled by control signals to drive two rotating shafts, and the positions and attitudes of the first guide component and the second guide component can be adjusted respectively to optimize the air resistance of the first vehicle in different scenarios and meet the driving needs in different scenarios.
[0259] In one possible embodiment, the first moving member includes a first lifting rod, and the second moving member includes a second lifting rod. For details, please refer to Scheme 3 above, which will not be repeated here.
[0260] At this time, the control signal is used to control the first driving component to drive the first lifting rod to rise and fall, thereby driving the first guide component to rise and fall. The control signal is also used to control the second driving component to drive the second lifting rod to rise and fall, thereby driving the two second guide components to rise and fall.
[0261] It is understood that in the embodiments of this application, the first moving component includes a first lifting rod, and the second moving component includes a second lifting rod. The first lifting rod can be driven to rise and fall by the first driving component through the control signal, thereby driving the first guide component to rise and fall, so as to adjust the position and attitude of the first guide component. Alternatively, the second driving component can be driven to rise and fall by the control signal, thereby driving the second guide component to rise and fall, so as to adjust the position and attitude of the second guide component. This results in the first guide component having a different position and attitude under different scenarios, and / or the second guide component having a different position and attitude.
[0262] Through the embodiments of this application, two driving components can be controlled by control signals to drive two lifting rods, and the positions and attitudes of the first guide and the second guide can be adjusted respectively to optimize the air resistance of the first vehicle in different scenarios and meet the driving needs in different scenarios.
[0263] In one possible embodiment, under the scenario described above, step S702 can be implemented in ways including but not limited to the following:
[0264] Based on the first information, the control device determines that the first vehicle is in a parked state, or the first vehicle's speed is less than a sixth threshold, or the slope of the road surface where the first vehicle is located is greater than a seventh threshold, and then generates a first control signal.
[0265] At this time, the first control signal is used to control at least one driving member to drive at least one moving member to move, so as to move the first guide member to the first position and to move the two second guide members to the second position.
[0266] Wherein, the height of the first guide member relative to at least one moving member in the first position is greater than an eighth threshold, and / or, the height of the second guide member relative to at least one moving member in the second position is greater than a ninth threshold.
[0267] Optionally, the sixth, seventh, eighth, and ninth thresholds are not fixed values and can be adjusted according to different scenarios to improve the accuracy of the position and attitude of the first and second guide members. This application embodiment does not limit this.
[0268] Alternatively, please refer to the relevant explanation of Scenario 1 above, which will not be repeated here.
[0269] It is understood that, through the embodiments of this application, in scenarios where the first vehicle is parked, traveling at low speed, or on a road with a large slope, the first control signal can be used to control and adjust the first guide to a first position and the second guide to a second position, so that the ground clearance of the first guide in the first position is sufficient, and / or the ground clearance of the second guide in the second position is sufficient, avoiding the guide from scraping against the ground, thereby meeting the driving needs in the above scenarios and improving the safety and reliability of the vehicle.
[0270] In one possible embodiment, under scenario two above, step S702 can be implemented in ways including but not limited to the following:
[0271] Based on the first information, the control device determines that if the speed of the first vehicle is greater than the tenth threshold, it generates a second control signal.
[0272] At this time, the second control signal is used to control at least one driving member to drive at least one moving member to move, so as to move the first guide member to the third position and to move the two second guide members to the fourth position.
[0273] Among them, the wind resistance corresponding to the first guide member in the third position is less than the wind resistance corresponding to the second guide member in the fourth position.
[0274] Optionally, the tenth threshold is not a fixed value and can be adjusted according to different scenarios to improve the accuracy of the position and attitude of the first and second guide members. This application embodiment does not limit this.
[0275] Alternatively, please refer to the relevant explanation of Scenario 2 above, which will not be repeated here.
[0276] It is understood that, through the embodiments of this application, in the scenario where the first vehicle is traveling at high speed, the first guide member can be adjusted to the third position and the second guide member can be adjusted to the fourth position by the second control signal, so that the wind resistance of the first guide member in the third position is less than the wind resistance of the second guide member in the fourth position, thereby reducing the air resistance of the first vehicle in the above scenario, thus meeting the driving requirements in the above scenario, reducing the energy consumption of the vehicle, and improving the vehicle's range.
[0277] In one possible embodiment, under scenario three above, step S702 can be implemented in ways including but not limited to the following:
[0278] Based on the first information, the control device determines that if the first vehicle's speed is greater than the eleventh threshold and it is in a braking state, it generates a third control signal.
[0279] At this time, the third control signal is used to control at least one driving member to drive at least one moving member to move, so as to move the first guide member to the fifth position and to move the two second guide members to the sixth position.
[0280] Among them, the wind resistance corresponding to the first guide member in the fifth position is greater than the wind resistance corresponding to the second guide member in the sixth position.
[0281] Optionally, the eleventh threshold is not a fixed value and can be adjusted according to different scenarios to improve the accuracy of the position and attitude of the first and second guide members. This application embodiment does not limit this.
[0282] Alternatively, please refer to the relevant explanation of Scenario 3 above, which will not be repeated here.
[0283] It is understood that, through the embodiments of this application, in the scenario where the first vehicle is traveling at high speed and braking, the first guide member can be adjusted to the fifth position and the second guide member can be adjusted to the sixth position by the third control signal, so that the wind resistance corresponding to the first guide member at the fifth position is greater than the wind resistance corresponding to the second guide member at the sixth position, thereby increasing the air resistance and downforce of the first vehicle in the above scenario, thus meeting the driving requirements in the above scenario, assisting the vehicle in maintaining vehicle stability and rapid braking when braking at high speed, and improving the braking performance and safety of the vehicle.
[0284] Please see Figure 8 , Figure 8 This is a flowchart illustrating another control method provided in an embodiment of this application. This control method is applied in the field of vehicle technology, such as a control method for a flow guide device installed at a specific location on a vehicle body.
[0285] It is understood that the steps in the embodiments of this application can be regarded as described above. Figure 7 Reasonable variations or additions to the embodiments in this application; or, it is understood that the control methods in the embodiments of this application can also be regarded as embodiments that can be executed independently, and this application does not limit them.
[0286] It is understood that the control device in the embodiments of this application can be specifically referred to the above. Figure 7The relevant descriptions of the control device in this application will not be repeated here.
[0287] It is understood that the flow guiding device used in the control method of this application embodiment can be specifically referred to the above. Figure 7 The flow guiding device used in the control method described above, or you can refer to the above-mentioned... Figures 2 to 6 The flow guiding device shown is not limited in this embodiment.
[0288] Specifically, the control method includes, but is not limited to, the following steps:
[0289] Step 1: Before starting the vehicle, the flow control device is in the target position 1.
[0290] Alternatively, please refer to the above for details. Figure 2 , with the above Figure 2 Taking the illustrated guide device as an example, when the vehicle is parked, the guide device is in target position 1, that is, the guide plate 2012 in the first guide member 201 is horizontal to the ground, and the guide plate 2022 in the second guide member 202 is horizontal to the ground, so that the ground clearance of the first guide member 201 and / or the ground clearance of the second guide member 202 are sufficient, avoiding the first guide member 201 and the second guide member 202 from scraping against the ground, thereby improving the safety and reliability of the vehicle.
[0291] Step 2: Obtain vehicle information and environmental information.
[0292] Optionally, the vehicle information includes, but is not limited to, information such as the speed and acceleration of the first vehicle.
[0293] Optionally, the environmental information of the vehicle includes, but is not limited to, information such as road slope and obstacles.
[0294] Step 3: Based on the vehicle information and the surrounding environment, control and adjust the position and attitude of the airflow guiding device.
[0295] Step 4: If the vehicle speed is greater than the preset threshold, the flow guiding device will be adjusted to the target position 2.
[0296] Alternatively, please refer to the above for details. Figure 5 , Figure 5 This can be considered as the above. Figure 2 The diagram shows the structure of the flow guiding device after rotating 90° counterclockwise or 270° clockwise. Figure 5 Taking the flow guiding device shown as an example, in the scenario where the vehicle is traveling at high speed, the flow guiding device is controlled to adjust to the target position 2, that is, to adjust the flow guide plate 2011 in the first flow guide 201 to be horizontal with the ground, and to adjust the flow guide plate 2022 in the second flow guide 202 to be vertical with the ground.
[0297] At this point, for the area between the left and right wheels of the vehicle, since the deflector 2011 in the first guide member 201 is horizontal to the ground, the air resistance in this area under the above scenario can be reduced. For the area in front of the left and right wheels of the vehicle, since the deflector 2022 in the second guide member 202 is perpendicular to the ground, the airflow passes through the deflector 2022 first and then through the wheels. Compared with the airflow passing directly through the wheels, the air resistance in the area in front of the wheels under the above scenario can be reduced.
[0298] Therefore, by controlling the airflow guide device to adjust to the target position 2, the air resistance of the vehicle in the above-mentioned environment can be reduced, thereby reducing the vehicle's energy consumption and improving its range.
[0299] Step 5: If a braking signal is detected, control the flow guiding device to adjust to the target position 3.
[0300] Alternatively, please refer to the above for details. Figure 6 , Figure 6 This can be considered as the above. Figure 5 The diagram shown illustrates the structure of the flow guiding device after it has been rotated 180°. Figure 6 Taking the flow guiding device shown as an example, in the scenario where the vehicle is traveling at high speed and braking, the flow guiding device is controlled to adjust to the target position 3, that is, to adjust the flow guide plate 2012 in the first flow guide 201 to be perpendicular to the ground, and to adjust the flow guide plate 2021 in the second flow guide 202 to be horizontal to the ground.
[0301] At this point, for the area between the left and right wheels of the vehicle, since the deflector 2012 in the first guide vane 201 is perpendicular to the ground, the air resistance in this area can be increased in the above scenario. For the area in front of the left and right wheels of the vehicle, since the deflector 2021 in the second guide vane 202 is horizontal to the ground, the airflow passes directly over the wheels. Compared to the airflow passing through the deflector 2021 first and then over the wheels, this increases the air resistance in the area in front of the wheels in the above scenario.
[0302] Therefore, by controlling the airflow guiding device to the target position 3, the air resistance of the first vehicle in the above scenario can be increased, thereby assisting the vehicle in maintaining vehicle stability and rapid braking when braking at high speed, and improving the vehicle's braking performance and safety.
[0303] Step 6: If the vehicle speed is less than or equal to the preset threshold, or if the slope is greater than the preset threshold, then control the flow guiding device to adjust to the target position 1.
[0304] Alternatively, please refer to the above for details. Figure 2 , with the above Figure 2Taking the illustrated guide device as an example, in scenarios where the first vehicle is traveling at low speed or the road surface where the first vehicle is located has a large slope, the guide device is controlled to adjust to target position 1, that is, to adjust the guide plate 2012 in the first guide member 201 to be horizontal with the ground, and to adjust the guide plate 2022 in the second guide member 202 to be horizontal with the ground, so that the ground clearance of the first guide member 201 and / or the ground clearance of the second guide member 202 are sufficient, avoiding the first guide member 201 and the second guide member 202 from scraping with the ground, thereby meeting the driving needs in the above scenarios and improving the safety and reliability of the vehicle.
[0305] It is understood that the airflow guiding components in the airflow guiding device of this application embodiment are designed and arranged in segments according to the positions of the left and right wheels of the vehicle. Some segments of the airflow guiding components are located in front of the left and right wheels of the vehicle, respectively, while others are located in the area between the left and right wheels. Therefore, to address the differences in air resistance requirements of the vehicle in different scenarios, as well as the differences in air resistance requirements of different parts of the vehicle, the position and orientation of the segmented airflow guiding components can be adjusted to meet these differences in air resistance requirements.
[0306] Through the embodiments of this application, based on vehicle information and / or environmental information, the position and attitude of the segmented air guide can be controlled and adjusted differently in different scenarios to optimize the air resistance of the vehicle in different scenarios, thereby meeting the driving needs in different scenarios.
