Technical Field

[0001] The present invention belongs to the technical field of vehicle control, and in particular relates to a method, device, equipment and medium for controlling a vehicle exterior rearview mirror. Background Art

[0002] Exterior rearview mirrors on existing vehicles generally have a folding function, the purpose of which is to protect pedestrians and reduce the width of the vehicle, thereby reducing the risk of collision when the vehicle is parked or driving in a narrow lane and when vehicles meet.

[0003] At present, the methods of controlling the folding of the exterior mirrors mainly include manual control and electric control. Manual control requires the driver to get out of the car or reach out of the window to push the rearview mirror toward the car body to fold it up. This control method is relatively cumbersome to operate; electric control controls the folding and unfolding of the rearview mirror through buttons or switches inside the car. Although this control method is relatively convenient, it still requires the driver to actively choose to control it. It cannot guarantee that the driver can choose to control the folding of the exterior mirrors in time when there is a risk of collision. There are certain safety hazards. In addition, this control method can only control the exterior mirrors on both sides of the vehicle to unfold or fold at the same time. The control method has limitations and cannot adaptively control the exterior mirrors according to different working conditions, and the fuel economy is poor. Summary of the invention

[0004] The purpose of the present invention is to provide a vehicle exterior rearview mirror control method, device, equipment and medium, which can adaptively control the expansion or folding of the exterior rearview mirrors on one side or both sides of the vehicle according to different working conditions, thereby solving the technical problems in the prior art that the exterior rearview mirrors cannot be adaptively controlled according to different working conditions and the fuel economy is poor.

[0042] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0043] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0044] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0045] In order to solve the technical problem that the existing technology cannot adaptively control the vehicle's exterior rearview mirrors according to different working conditions and has poor fuel economy, please refer to Figure 1 As shown, the present invention provides a vehicle exterior rearview mirror control method, which adaptively controls the vehicle exterior rearview mirrors on one side or both sides to unfold or fold according to different working conditions. The vehicle exterior rearview mirror control method comprises the following steps:

[0046] S100: Determine the current operating condition category of the vehicle according to the vehicle navigation information;

[0047] S200: Acquiring road condition information around the vehicle under different working condition categories;

[0048] S300: Controlling the unfolding or folding of the exterior rearview mirrors on one or both sides of the vehicle according to the current operating condition of the vehicle and the road condition information around the vehicle.

[0049] It should be noted that the system for controlling the vehicle's exterior rearview mirrors of the present invention comprises a map / navigation, a front camera, an angular millimeter-wave radar, a controller, a reminder system, and an execution system. The map / navigation is installed inside the vehicle's head unit and can provide map information and navigation in front of the vehicle. The front camera is installed near the vehicle's interior rearview mirror and can collect information about targets and road conditions in front of the vehicle. The angular millimeter-wave radar is set at the four corners inside the front and rear bumpers of the vehicle and can provide information about targets around the vehicle. The controller is installed in the vehicle's cockpit and can calculate whether the folding of the exterior rearview mirrors and folding of the single-side or double-side exterior rearview mirrors are met based on the information provided by the sensor, and send a reminder request to the reminder system, and send a control request to the execution system according to the feedback result of the reminder system. When the conditions for folding the exterior rearview mirrors are met, the reminder system reminds the driver to confirm whether to fold the exterior rearview mirrors. When the conditions for folding the exterior rearview mirrors are met, the execution system executes the folding of the exterior rearview mirrors. It is worth noting that the number of sensors can be one or more. For example, if the number of front cameras is multiple, the information collected by the multiple front cameras is fused to ensure the integrity and accuracy of the information.

[0050] The steps of the above-mentioned vehicle exterior rearview mirror control method will be discussed in detail below.

[0051] First, step S100 is executed, that is, the operating condition category of the current vehicle is determined according to the navigation planned driving route.

[0052] In an exemplary embodiment of the present application, see Figure 2 As shown, in step S100, determining the current operating condition category of the vehicle according to the vehicle navigation information further includes the following steps:

[0053] S110: Obtaining the road width, road type, lane change information, roadblock information and overtaking and meeting conditions of the current driving section of the vehicle from the vehicle navigation information;

[0054] S120: Determine the current operating condition category of the vehicle according to the road width, road type, lane change information, roadblock information, and overtaking or meeting conditions;

[0055] Specifically, if the width of the road the vehicle is currently traveling on is greater than the preset width and the type of the road ahead is a straight section, it is the first operating condition; if the width of the road the vehicle is currently traveling on is greater than the preset width and the road ahead needs to change lanes, it is the second operating condition; if the width of the road the vehicle is currently traveling on is greater than the preset width and the type of the road ahead is a curve, it is the third operating condition; if the width of the road the vehicle is currently traveling on is less than or equal to the preset width and the vehicle is about to overtake or meet, it is the fourth operating condition; if the width of the road the vehicle is currently traveling on is less than or equal to the preset width and there are roadblocks on both sides of the road, it is the fifth operating condition.

[0056] In an exemplary embodiment of the present application, the operating condition categories include a wide road straight driving condition, a wide road lane changing condition, a wide road turning condition, a narrow road overtaking condition, and a narrow road obstacle avoiding condition.

[0057] Specifically, the wide road straight driving condition is the first working condition, the wide road lane changing condition is the second working condition, the wide road turning condition is the third working condition, the narrow road overtaking condition is the fourth working condition, and the narrow road obstacle avoidance condition is the fifth working condition.

[0058] It should be noted that before controlling the vehicle's exterior mirrors, the driver needs to turn on the automatic folding exterior mirror auxiliary system function in advance and set the navigation route in the vehicle navigation system. In addition, in this embodiment, the preset width for distinguishing between wide roads and narrow roads is the standard road width, that is, a road is wide when the road width is greater than 3m, and a road is narrow when the road width is less than or equal to 3m.

[0059] Next, step S200 is executed to obtain the road condition information around the vehicle under different working condition categories.

[0060] In an exemplary embodiment of the present application, the road condition information around the vehicle under different operating conditions is obtained by a vehicle-mounted camera and a vehicle-mounted radar, wherein the road condition information around the vehicle obtained under different operating conditions is different.

[0061] In an exemplary embodiment of the present application, the road condition information around the vehicle includes traffic conditions, lane change direction, curve direction, the vehicle's current lane, overtaking direction, lateral distance between adjacent vehicles and the vehicle, and height and width of roadblocks on both sides of the road.

[0062] Specifically, if it is the first working condition, the number and speed of other vehicles currently around the vehicle are obtained, and the traffic conditions of the current driving section of the vehicle are determined based on the number and speed of other vehicles currently around the vehicle. If it is the second working condition, the direction of lane change is obtained. If it is the third working condition, the direction of the curve and the lane the vehicle is currently driving are obtained. If it is the fourth working condition, the lateral distance between the adjacent target vehicle and the vehicle itself and the direction of meeting or overtaking are obtained. If it is the fifth working condition, the height and width of the roadblocks on both sides of the road are obtained. It should be noted that when the vehicle is in the first working condition, the traffic conditions of the current driving section of the vehicle are determined by judging whether the number of other vehicles currently around the vehicle is greater than the preset number and whether the average speed is less than the preset speed. If yes, there is traffic congestion on the current driving section of the vehicle. If not, there is no traffic congestion on the current driving route of the vehicle.

[0063] If the current vehicle is in the first working condition, that is, the width of the road on which the vehicle is currently traveling is greater than the preset width and the road ahead is a straight section, it should be noted that the straight section refers to the vehicle traveling straight in the current lane without changing lanes. At this time, it is necessary to obtain the number and speed of other vehicles currently around the vehicle, and determine the traffic conditions of the vehicle's current driving route based on the number and speed of other vehicles currently around the vehicle. If the number of other vehicles currently around the vehicle is greater than the preset number and the average speed is less than the preset speed, there is traffic congestion in the current driving section of the vehicle, otherwise there is no traffic congestion. If the current vehicle is in the second working condition, that is, the width of the road on which the vehicle is currently traveling is greater than the preset width and the road ahead needs to change lanes, then the lane change direction is obtained, and the lane change direction includes changing lanes to the left or to the right. If the current vehicle is in the third working condition, that is, the width of the road on which the vehicle is currently traveling is greater than the preset width and the road ahead is a curve, then the curve direction and the lane the vehicle is currently traveling in are obtained, for example, turning left or turning right and the vehicle is currently traveling in the innermost lane, the middle lane or the outermost lane. If the current vehicle is in the fourth working condition, that is, the width of the road on which the vehicle is currently traveling is less than or equal to the preset width and the vehicle is about to overtake or meet, then the lateral distance between the target vehicle and the own vehicle and the direction of meeting or overtaking are obtained, for example, the target vehicle is meeting or overtaking on the left side of the own vehicle, and the target vehicle is meeting or overtaking on the right side of the own vehicle. If the current vehicle is in the fifth working condition, that is, the width of the road on which the vehicle is currently traveling is less than or equal to the preset width and there are roadblocks on both sides of the road, then the height of the roadblocks on both sides of the road and the width between the roadblocks on both sides are obtained.

[0064] Finally, step S300 is executed, that is, according to the current working condition category of the vehicle and the road condition information around the vehicle, the exterior rearview mirrors on one side or both sides of the vehicle are controlled to be unfolded or folded.

[0065] In an exemplary embodiment of the present application, based on the current operating condition category of the vehicle and the road condition information around the vehicle, the exterior rearview mirrors on one or both sides of the vehicle are automatically controlled to be unfolded or folded without the driver's confirmation.

[0066] In an exemplary embodiment of the present application, based on the vehicle's current operating condition category and the road conditions around the vehicle, the driver confirms whether to control the vehicle's one or both sides of the exterior rearview mirror to be unfolded or folded. If so, the vehicle's one or both sides of the exterior rearview mirror are immediately controlled to be unfolded or folded. If not, the vehicle's exterior rearview mirrors are maintained in their initial state.

[0067] It should be noted that the automatic control of the vehicle's exterior rearview mirrors or the control of the vehicle's exterior rearview mirrors by the driver's confirmation and based on the confirmation results, both can be pre-set and switched according to user needs. In this embodiment, the implementation method can be switched through a button or switch in the vehicle's cockpit. Of course, in other embodiments, it can also be implemented in other ways.

[0068] In an exemplary embodiment of the present application, see Figure 3 As shown, in step S300, the control of unfolding or folding the exterior rearview mirrors on one side or both sides of the vehicle according to the current working condition category of the vehicle and the road condition information around the vehicle further includes the following steps:

[0069] S310: If the lane change condition is a wide road, control the exterior rearview mirror on the corresponding side of the vehicle to unfold according to the lane change direction;

[0070] S320: If the vehicle is in a wide road turning condition, the exterior rearview mirror on the corresponding side of the vehicle is controlled to unfold according to the direction of the turning and the current lane of the vehicle;

[0071] S330: If the vehicle is overtaking on a narrow road, the exterior rearview mirror on the corresponding side of the vehicle is controlled to be folded according to the lateral distance between the adjacent vehicle and the vehicle and the overtaking direction;

[0072] It should be noted that after the vehicle is powered on for the first time, the initial state of the vehicle's exterior rearview mirrors is that both side exterior rearview mirrors are unfolded.

[0073] When the vehicle is in the first operating condition, that is, the wide road straight driving condition, if there is traffic congestion on the current driving section of the vehicle, the dual-side exterior rearview mirrors are kept unfolded; if there is no traffic congestion on the current driving section of the vehicle, the dual-side exterior rearview mirrors are controlled to be folded.

[0074] When the vehicle is in the second operating condition, that is, the lane changing condition on a wide road, if the lane changing direction is to the left, only the left side exterior rearview mirror of the vehicle is controlled to unfold; if the lane changing direction is to the right, only the right side exterior rearview mirror of the vehicle is controlled to unfold.

[0075] When the vehicle is in the third operating condition, that is, the wide road turning condition, if the curve direction is a left turn and the vehicle's current lane is the innermost lane, only the right side exterior rearview mirror of the vehicle is controlled to unfold; if the curve direction is a left turn and the vehicle's current lane is the outermost lane, only the left side exterior rearview mirror of the vehicle is controlled to unfold; if the curve direction is a left turn and the vehicle's current lane is the middle lane, then both side exterior rearview mirrors of the vehicle are controlled to unfold; if the curve direction is a right turn and the vehicle's current lane is the innermost lane, only the left side exterior rearview mirror of the vehicle is controlled to unfold; if the curve direction is a right turn and the vehicle's current lane is the outermost lane, only the right side exterior rearview mirror of the vehicle is controlled to unfold; if the curve direction is a right turn and the vehicle's current lane is the middle lane, then both side exterior rearview mirrors of the vehicle are controlled to unfold.

[0076] When the vehicle is in the fourth operating condition, i.e., the narrow road overtaking condition, if the lateral distance between the adjacent target vehicle and the own vehicle is less than the preset distance and the target vehicle is meeting or overtaking on the left side of the own vehicle, only the left side exterior mirror of the vehicle is controlled to unfold; if the lateral distance between the target vehicle and the own vehicle is less than the preset distance and the target vehicle is meeting or overtaking on the right side of the own vehicle, only the right side exterior mirror of the vehicle is controlled to unfold.

[0077] When the vehicle is in the fifth working condition, that is, the narrow road obstacle avoidance condition, if the height of the obstacles on both sides of the road is higher than the position of the vehicle's exterior rearview mirrors and the width between the obstacles on both sides is smaller than the width of the vehicle when the exterior rearview mirrors are opened, the vehicle's exterior rearview mirrors on both sides are controlled to fold.

[0078] In summary, the present invention provides a vehicle exterior rearview mirror control method, which determines the current working condition category of the vehicle according to the vehicle navigation information, obtains the vehicle surrounding road condition information under different working condition categories, and controls the vehicle's single or double side exterior rearview mirrors to unfold or fold according to the vehicle's current working condition category and the vehicle surrounding road condition information. The method controls the folding of the vehicle's double side exterior rearview mirrors when there is no need to observe the working condition of the exterior rearview mirrors, which can reduce wind resistance and noise. In addition, when only one side of the exterior rearview mirror needs to be observed, the exterior rearview mirror on the corresponding side of the vehicle is controlled to unfold, without the need to unfold both sides of the vehicle's exterior rearview mirrors at the same time. The vehicle's exterior rearview mirrors can be adaptively controlled to unfold or fold according to different working condition requirements, thereby improving fuel economy.
