Description

Technical Field

[0001] This application relates to the field of vehicle seat technology, and in particular to a control method, device, seat controller, and vehicle for the side wing support of an automobile seat. Background Technology

[0002] Currently, many vehicle seats are equipped with side wing supports on both sides of the backrest and seat cushion. These side wing supports are triggered during dynamic driving scenarios such as turning, acceleration, and deceleration, thereby providing lateral support to the driver and passengers, reducing the user's body tilt, ensuring the user's riding stability, and effectively improving the user's riding comfort and safety.

[0003] In related technologies, there are many ways to trigger seat side wing support. For example, judging the vehicle's acceleration and angular velocity, the side wing airbags are quickly inflated to provide side wing support to the occupants; another example is to quickly adjust the side wing support based on the vehicle's driving status information to facilitate timely and proactive control of the side wing support; yet another example is to dynamically adjust the rotational position of the side wing support between the inner and outer sides of the vehicle seat based on vehicle speed and steering information to achieve the purpose of side wing support; still another example is to set the torso width level of the vehicle seat side wing according to the width of the human torso, and further calibrate the adjustment gears of the vehicle seat side wing for different lateral acceleration levels under each torso width level, automatically adjusting to the corresponding gear to provide lateral support to the user based on the vehicle's lateral acceleration.

[0004] However, the relevant technologies require sensor-based information for triggering the seat side wing support. This involves using sensors to collect data such as vehicle speed, acceleration, angular velocity, and user information to determine whether to trigger the system. However, this process suffers from a certain delay, making true real-time calculation impossible and limiting accuracy. Furthermore, the reliability of sensor signal acquisition is somewhat limited, impacting the user experience and failing to effectively meet user needs. These issues urgently need to be addressed. Summary of the Invention

[0005] This application provides a control method, device, seat controller, and vehicle for the side wing support of an automobile seat, in order to solve the problem in the related technology that relies on information collected by sensors as the trigger judgment basis, which leads to the uncontrollability of the opening of the side wing support, cannot guarantee the accuracy and reliability of the support control, affects the user experience, cannot effectively guarantee the user needs, and reduces user stickiness.

[0006] The first aspect of this application provides a control method for the side wing support of an automobile seat, comprising the following steps: acquiring lateral acceleration information and forward acceleration information of at least some trajectory points in the vehicle's driving trajectory; identifying at least one open trajectory point based on the lateral acceleration information and the forward acceleration information; and opening the side wing support of the vehicle seat when the vehicle is detected to have traveled to any of the open trajectory points.

[0007] Through the above technical means, the embodiments of this application can determine the trigger position of the seat side wing support in advance based on the lateral acceleration information and forward acceleration information of the trajectory points of the driving trajectory. Thus, when the trigger position is reached, the seat side wing support is accurately opened, effectively avoiding the limitations of relying on information collected by sensors as the trigger judgment basis. This effectively improves the accuracy and reliability of support control, making it more reliable and practical. It also effectively enhances the user experience, ensures usage needs, increases user stickiness, and improves the riding stability and comfort of drivers and passengers.

This allows the vehicle to quickly adapt to new driving conditions in complex roads or sudden situations, thereby ensuring driving safety and forward-looking control of seat side support.

[0016] Optionally, in one embodiment of this application, the method further includes: receiving environmental data of the actual location of the vehicle; and adjusting the driving trajectory based on the environmental data to generate a new driving trajectory.

[0017] Through the above technical means, the embodiments of this application can adjust the driving trajectory in real time according to environmental data to generate a new driving trajectory. It can provide real-time path optimization and selection capabilities, avoid unchanging control methods, better achieve adaptive adjustment, and enable the vehicle to select the safest, smoothest or most convenient driving trajectory in complex or changing road environments. At the same time, it can adaptively and accurately control the opening or closing of the vehicle seat side wing support, and achieve precise matching between seat support and vehicle dynamic state.

[0019] Through the above technical means, the embodiments of this application can determine the trigger position of the seat side wing support in advance based on the lateral acceleration information and forward acceleration information of the trajectory points of the driving trajectory. Thus, when the trigger position is reached, the seat side wing support is accurately opened, effectively avoiding the limitations of relying on information collected by sensors as the trigger judgment basis. This effectively improves the accuracy and reliability of support control, making it more reliable and practical. It also effectively enhances the user experience, ensures usage needs, increases user stickiness, and improves the riding stability and comfort of drivers and passengers. It achieves precise matching between seat support and vehicle driving scenarios, making it safer and more reliable.

This can provide the most convenient and suitable driving trajectory. At the same time, key trajectory points can be identified based on the driving trajectory, providing a reliable trajectory reference for seat side wing support control, thereby bringing users higher travel efficiency and a more comfortable riding experience.

Detailed Implementation

[0037] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0038] The following description, with reference to the accompanying drawings, outlines a method, apparatus, seat controller, and vehicle for controlling the side wing support of an automotive seat, reflecting embodiments of this application. Addressing the technical problem mentioned in the background art, where relying on sensor-collected information as the trigger for side wing support leads to uncontrollable activation of the side wing support, compromising accuracy and reliability, impacting user experience, failing to effectively meet user needs, and reducing user engagement, this application provides a method for controlling the side wing support of an automotive seat. In this method, an intelligent driving system acquires the vehicle's driving trajectory and, based on the lateral and forward acceleration information of at least some trajectory points, controls the side wing support of the vehicle to open or close under appropriate conditions. The method dynamically adjusts the side wing support according to the driving trajectory and the vehicle's actual driving state, providing support matching the current driving state, achieving accurate response of the side wing support, improving ride comfort and stability, reducing the user's lateral tilt during vehicle acceleration, deceleration, and cornering, mitigating body displacement, thereby improving ride comfort and driving safety, enhancing user trust and engagement with the vehicle, and improving the overall riding experience and user satisfaction. This solves the problem that related technologies rely on sensor-collected information as the basis for determining whether the seat side wing support will activate, which leads to uncontrollability in the activation of the seat side wing support, affects the user experience, fails to effectively guarantee user needs, and reduces user stickiness.

[0039] Before describing the control method for the side wing support of the car seat provided in the embodiments of this application, the relevant structures of the side wing support of the seat involved in the embodiments of this application will be illustrated by example.

[0040] like Figure 1 As shown, the related structures of the seat side wing support may include, but are not limited to, the seat side wing support 101, backrest 102, seat cushion 103, seat slide rail 104 and its connecting parts 105, which together constitute the vehicle's seat system. The seat system can be intelligently managed by the seat controller, which can, but is not limited to, adjust the angles of the seat side wing support 101 and backrest 102, the position of the seat cushion 103 and other adjustable components to provide users with personalized support and comfort, while improving riding safety and riding experience.

[0041] The seat side wing support 101 can adopt various structural forms, such as mechanical and inflatable. Mechanical seat side wing support provides lateral support through fixed foam, springs, or adjustable mechanisms, offering a simple and reliable structure. Inflatable seat side wing support changes the thickness and support strength of the side wing by inflating and deflating airbags, allowing adjustment according to driving conditions or passenger size, but with a relatively long response time. Alternatively, the seat side wing support 101 can be controlled based on parameters such as vehicle speed and acceleration, but this has certain drawbacks: it may be accidentally triggered in non-turning situations, causing premature activation of the seat side wing support; and the support may only activate after the vehicle has entered a turning condition, failing to provide timely lateral support, thus affecting ride comfort and safety.

[0042] The control method for automotive seat side wing support provided in this application embodiment can be applied to various seat structures, and its form is not limited to mechanical and pneumatic types. That is, although the above seat side wing support is used as an example, those skilled in the art should understand that any seat side wing can be configured in the following way; it should be noted that... Figure 1 The structural design of the seat side wing is merely illustrative. This application is not limited to this single structural design. In this way, it can solve the problem of false triggering or delayed triggering of the seat side wing support mentioned above, provide users with accurate lateral support, and thus improve riding comfort and safety.

[0043] Specifically, Figure 2 A flowchart illustrating a control method for side wing support of an automobile seat provided in an embodiment of this application.

[0044] like Figure 2 As shown, the control method for the side wing support of the car seat includes the following steps: In step S201, lateral acceleration information and forward acceleration information of at least some trajectory points in the vehicle's driving trajectory are obtained.

[0045] The vehicle's driving trajectory can be understood as the planned trajectory of the vehicle over a certain period of time in the future, or it can be the planned trajectory from the current location, the starting point, or any location to the corresponding destination. It can be obtained directly from the vehicle's intelligent driving system or generated based on the vehicle's onboard map, without any specific limitations.

[0046] For example, when the vehicle is in an intelligent driving scenario, and the vehicle travels from point A to point B according to the planned trajectory, the car seat controller can obtain the planned trajectory from the vehicle controller or the intelligent driving system, and thus use the complete or partial planned trajectory to determine the user's driving trajectory required in the subsequent embodiments of this application.

[0047] It should be noted that each trajectory point in the driving trajectory can include lateral acceleration information and forward acceleration information. Lateral acceleration information can be understood as the acceleration of the vehicle in the lateral direction, which can be used to determine whether the vehicle is turning and the degree of turning. Forward acceleration information can be understood as the acceleration of the vehicle in the forward direction, which can be used to determine the acceleration or deceleration state of the vehicle. Both can be obtained from information pre-recorded in the map information or calculated from the driving trajectory, without specific restrictions here.

[0048] In summary, the embodiments of this application can accurately obtain the vehicle's acceleration information in all directions within the next few seconds based on the driving trajectory, thereby providing a judgment for accurately triggering seat support, solving the problems of false triggering and delayed triggering, providing users with timely and accurate seat side support, and improving user riding comfort, stability and driving safety.

[0049] Optionally, in one embodiment of this application, obtaining the vehicle's driving trajectory includes: receiving the user's navigation destination and obtaining the vehicle's current position when the vehicle is in intelligent driving mode; generating a driving trajectory based on the navigation destination and the current position to obtain lateral acceleration information and forward acceleration information of at least some trajectory points in the driving trajectory.

[0050] It is understood that the complete planned trajectory is used as an example to describe the driving trajectory. The intelligent driving scenario can be, but is not limited to, the state in which the vehicle is in autonomous driving or assisted driving mode and the vehicle's intelligent control system takes over part or all of the driving tasks. No specific limitation is made here. The driving trajectory can be obtained directly from the in-vehicle navigation system. It can be obtained from the most fuel-efficient, shortest distance between the navigation destination and the current location or the route selected by the user.

[0051] As a concrete example, when a vehicle intelligent control system reaches Level 2 or above, it typically has trajectory planning capabilities. Such systems are usually equipped with high-precision sensors, cameras, radar, and positioning modules, which can generate future driving trajectories in real time based on the current location and navigation target point, including but not limited to parameters such as path curvature, vehicle speed, and acceleration. The system can control the vehicle's steering based on this trajectory information, calculate the optimal steering command, and thus achieve partially or fully automatic lateral vehicle control, improving driving stability, safety, and the overall driving experience.

[0052] Specifically, such as Figure 3 As shown in the embodiments of this application, the vehicle can be regarded as a moving entity with radius r1, and the obstacle can be regarded as a static or dynamic obstacle with radius r2 and coordinates (x1, x2). The vehicle intelligent control system can calculate the distance dis from the obstacle to any point on the planned trajectory to determine whether the trajectory has a potential collision with the obstacle, and adjust the planned trajectory if necessary. The trajectory planning may cover parameters such as path curvature, speed, and acceleration in the next few seconds to ensure smooth and safe vehicle driving.

[0053] In summary, the embodiments of this application can utilize the trajectory planning function of the vehicle intelligent control system to obtain parameters such as path curvature, speed, and acceleration of the future driving trajectory, thereby providing a basis for the dynamic control of the seat side wing support. This enables the side wing support to be opened or closed in a timely manner according to the vehicle's driving status, providing lateral support to the user during acceleration, deceleration, or turning, thereby improving riding comfort and safety.

[0054] Optionally, in one embodiment of this application, generating a driving trajectory based on the navigation destination and the current location includes: generating multiple planned trajectories based on the navigation destination and the current location, and after determining the target planned trajectory from the multiple planned trajectories, using at least a portion of the target planned trajectory as the driving trajectory based on the current location and a preset duration.

[0055] It is understood that this description refers to at least a portion of the target planned trajectory as the driving trajectory. In this embodiment of the application, the corresponding portion of the planned trajectory can be extracted as the driving trajectory based on the current position of the vehicle and a certain duration, according to parameters such as the path curvature, vehicle speed, and acceleration of the planned trajectory generated in the intelligent driving scenario, rather than using the complete planned trajectory.

[0056] The preset duration can be a fixed duration, such as 10 minutes; or it can be a dynamic duration calculated based on the driving trajectory. For example, the dynamic duration can be set according to road conditions (such as the difference between continuous turning road conditions and urban road conditions). It can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0057] In actual implementation, this application embodiment can select a driving trajectory based on a certain duration, rather than a complete trajectory with the final destination as the endpoint. This application embodiment can extract a portion of the target planned trajectory for a corresponding duration based on the current location and preset duration as the current driving trajectory, which can improve the efficiency and accuracy of calculation, improve the precision of the trajectory, and facilitate flexible adjustment and updating of the driving trajectory, thereby improving driving safety and control reliability.

[0058] Optionally, in one embodiment of this application, generating a driving trajectory based on the navigation destination and the current location includes: generating multiple planned trajectories based on the navigation destination and the current location, and using the planned trajectory that meets the preset optimal conditions as the driving trajectory.

[0059] There are many possible preset optimal conditions, such as the minimum number of traffic lights or the shortest estimated arrival time. These can be set by those skilled in the art based on the actual situation, and no specific restrictions are imposed here.

[0060] As one possible implementation method, this application embodiment can generate multiple candidate routes as planned trajectories based on the navigation destination and the vehicle's current location. Then, one of the planned trajectories can be automatically selected or selected by the user through interactive means as the vehicle's driving trajectory, and the trajectory point selection can be made based on the driving trajectory.

[0061] In the embodiments of this application, automatically selecting or having the user select one of the planned trajectories as the vehicle's driving trajectory can effectively improve the efficiency and accuracy of calculations, enhance the precision of the trajectory, make it more flexible and adaptable, and improve the adaptability of control.

[0062] Optionally, in one embodiment of this application, the embodiment further includes: receiving environmental data of the actual location of the vehicle; adjusting the driving trajectory based on the environmental data to generate a new driving trajectory.

[0063] In some cases, due to traffic congestion, road construction, emergencies, or changes in destination, the original driving trajectory may change at any time along the way. The embodiments of this application can realize adaptive route adjustment due to environmental factors based on the signals provided by the sensors, and reselect a new driving trajectory. For example, based on the current location and a certain time, the corresponding road segment is selected from the target planned trajectory as the new driving trajectory, and then a new trajectory point is planned.

[0064] In summary, the embodiments of this application can select a complete route or a portion thereof as the driving trajectory based on the vehicle's current location, destination, traffic conditions, road construction, emergencies, and other environmental factors, thereby improving the rationality and adaptability of the driving trajectory.

[0065] In step S202, at least one open trajectory point is identified based on the lateral acceleration information and the forward acceleration information.

[0066] As will be understood by those skilled in the art, "opening the trajectory point" can refer to a point where the vehicle's lateral acceleration and / or forward acceleration reaches a certain value, generating a lateral tilting force on the user, and therefore the vehicle should open the seat side bolsters at this position; for example, if the vehicle's lateral acceleration is greater than 2.0 m / s². 2 This generally indicates that the vehicle is making a sharp turn and needs side protection, or that the forward acceleration may exceed 1.5 m / s². 2 This generally indicates that the vehicle is accelerating significantly and is being protected. It can also be a combination of both conditions to provide more reliable protection. No specific restrictions are made here, and those skilled in the art can set it according to the actual situation.

[0067] This application embodiment can identify the opening trajectory point based on lateral acceleration information and forward acceleration information to trigger the automatic opening of the seat side wing support, providing users with accurate and timely lateral support. It can achieve dynamic support control synchronized with the actual driving state of the vehicle, thereby improving the accuracy of lateral support and ride comfort.

[0068] In step S203, if the vehicle is detected to have traveled to any open trajectory point, the side wing support of the vehicle's seat is opened.

[0069] In the embodiments of this application, the detection method may be, but is not limited to, based on whether the actual position of the vehicle coincides with the opening trajectory point. Once the actual position coincides with any opening trajectory point, a trigger condition is provided for the opening of the seat side wing support, and the seat side wing support is opened to provide support for the user.

[0070] The embodiments of this application can open the side wing support of the vehicle seat according to the opening trajectory point, providing users with accurate and timely lateral support, thereby improving riding comfort and enhancing safety during driving.

[0071] Optionally, in one embodiment of this application, the embodiment further includes: identifying at least one closed trajectory point based on lateral acceleration information and forward acceleration information of at least some trajectory points of the driving trajectory; and disabling the vehicle's seat side wing support when the vehicle is detected to have traveled to any closed trajectory point.

[0072] Specifically, the trajectory points that can be closed can be those where the vehicle's lateral acceleration is less than a certain value and / or its forward acceleration is less than a certain value, for example, lateral acceleration less than 0.5 m / s². 2 This generally indicates that the vehicle has finished turning or that the lateral force is small, requiring no intervention from the seat side bolsters, or that the forward acceleration is close to zero or below 0.2 m / s². 2This generally indicates that the vehicle has decelerated to a stable state and no side wing support is needed. This can be set by those skilled in the art according to the actual situation, and no specific restrictions are made here.

[0073] In this embodiment, the vehicle's operating status can be determined based on the above-mentioned closing conditions to meet the requirements for side wing closure. When the vehicle reaches any closing trajectory point, the automatic closure of the seat side wing support is triggered to avoid unnecessary energy consumption or structural resistance.

[0074] like Figure 4 The following describes the flow of the control method for the side wing support of an automobile seat according to a specific embodiment of this application. This embodiment includes, but is not limited to, the following steps: (1) Intelligent driving system: In step S401, the intelligent driving system determines whether the vehicle's intelligent driving function has been activated.

[0075] In step S402, after the intelligent driving function is activated, the intelligent driving system receives the navigation target location set by the user, as well as the environmental data provided by the vehicle sensors and the current positioning data.

[0076] The navigation target location can be provided by the vehicle map, and the vehicle sensors include, but are not limited to, data acquisition devices for environmental perception such as vehicle cameras and infrared sensors. The positioning information can be provided by the satellite navigation system or other high-precision positioning modules.

[0077] In step S403, the intelligent driving system plans the driving trajectory in real time.

[0078] It is understood that the embodiments of this application can plan the vehicle's driving trajectory in real time based on the navigation target location, environmental data and positioning information, and generate trajectory data for subsequent control.

[0079] (2) Seat controls: In step S404, the driving trajectory is received in real time.

[0080] It can be noted that the seat controller can receive the driving trajectory planned by the intelligent driving system in real time.

[0081] In step S405, it is determined whether the side wing support opening condition is met. If it is met, the side wing support is opened. It is also determined whether the side wing support closing condition is met. If it is met, the side wing support is closed.

[0082] The seat controller can analyze each trajectory point and determine whether the conditions for opening or closing the seat side wing support are met.

[0083] As one possible implementation, in this embodiment of the application, n can be set as the opening trajectory point of the seat side wing support, m as the closing trajectory point of the seat side wing support, a1 and b1 as the lateral and forward acceleration thresholds corresponding to the opening trajectory point, and a2 and b2 as the lateral and forward acceleration thresholds corresponding to the closing trajectory point.

[0084] Specifically, in this embodiment of the application, the conditions for opening the seat side wing support can be determined based on the following: when the lateral acceleration of the vehicle at the nth trajectory point is greater than a1 and the forward acceleration is greater than b1, the automatic opening of the seat side wing support is triggered.

[0085] Meanwhile, the embodiments of this application continuously determine the closing conditions of the seat side wing support: when the lateral acceleration of the vehicle at the m-th trajectory point is less than a2 and the forward acceleration is less than b2, the automatic closing of the seat side wing support is triggered, thereby realizing the dynamic adjustment of the seat side wing support according to the vehicle driving state.

[0086] In actual implementation, the sequence of the opening trajectory point n and the closing trajectory point m should satisfy m>n, meaning the closing trajectory point must be located after the opening trajectory point. This ensures that the seat side wing support can open first to provide lateral support during vehicle movement and then close at an appropriate time, avoiding insufficient occupant support due to premature closure or unnecessary drag and energy consumption due to delayed closure. The corresponding acceleration thresholds a1, b1, a2, and b2 can be reasonably determined based on actual measurement results, vehicle dynamic characteristics, and different driving scenarios. By obtaining the typical lateral and forward acceleration ranges of the vehicle during sharp turns, deceleration, or smooth driving through actual measurement data, it is possible to ensure that the seat side wing support accurately responds to the vehicle's motion state in real driving environments, thereby improving the timeliness and accuracy of lateral support while taking into account both ride comfort and safety.

[0087] According to the control method for the side wing support of the car seat proposed in the embodiments of this application, the intelligent driving system acquires the driving trajectory of the vehicle, and then controls the side wing support of the vehicle seat to open or close under appropriate conditions based on the lateral acceleration information and forward acceleration information of at least some trajectory points in the driving trajectory. The side wing support of the seat can be dynamically adjusted according to the driving trajectory and the actual driving state of the vehicle, providing a support effect that matches the current driving state, realizing accurate response of the side wing support of the seat, improving riding comfort and stability, reducing the user's side tilt feeling during vehicle acceleration, deceleration and turning, slowing down body displacement, thereby improving riding comfort and driving safety, enhancing the user's trust in the vehicle and user stickiness, and improving the overall riding experience and user satisfaction.

[0088] Next, the control device for the side wing support of an automobile seat according to an embodiment of this application is described with reference to the accompanying drawings.

[0102] Optionally, in one embodiment of this application, the generating unit includes: a second generating subunit.

[0103] The second generation subunit generates multiple planned trajectories based on the navigation destination and the current location. After determining the target planned trajectory from the multiple planned trajectories, it uses at least a portion of the target planned trajectory as the driving trajectory based on the current location and a preset duration.

[0104] Optionally, in one embodiment of this application, it further includes a receiving module and a generating module.
