[0002] With the rapid development of the automotive industry, vehicle safety performance has received increasing attention. Passenger safety is directly related to vehicle driving safety. Existing vehicle safety systems typically include active and passive safety systems. Active safety systems, such as AEBS (Automatic Emergency Braking System), can automatically apply the brakes when a potential hazard is detected; passive safety systems, such as airbags and seat belts, provide protection for passengers during a collision. However, the effectiveness of safety systems in protecting passengers in emergency situations still has certain limitations, especially in terms of vehicle dynamic adjustment and passenger posture control.

[0003] ECAS (Electronic Controlled Air Suspension) is a system that automatically adjusts suspension height and stiffness based on vehicle load, speed, and driving conditions, effectively improving vehicle comfort and stability. AEBS (Automatic Emergency Braking System) is a system that uses sensors to detect obstacles ahead and automatically activates the brakes when necessary to avoid or mitigate collisions. In these technologies, ECAS and AEBS typically operate independently, lacking a coordinated mechanism, and thus cannot provide more comprehensive and detailed protection for occupants in emergency situations.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0032] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0033] This invention provides a vehicle control method. The vehicle includes an electronically controlled air suspension system and an automatic emergency braking system. The electronically controlled air suspension system and the automatic emergency braking system are connected via an onboard communication network, enabling real-time data communication. For example, the electronically controlled air suspension system (ECAS) and the emergency braking system share real-time data via a CAN bus. The control method of this invention can be implemented in a vehicle controller. Specifically, it can be implemented in the central control unit of the vehicle controller.

[0034] Figure 1 This is a schematic diagram of an embodiment of the vehicle control method provided by the present invention.

[0035] like Figure 1 As shown, according to an embodiment of the present invention, the vehicle control method includes at least steps S110, S120 and S130.

[0036] Step S110: Receive obstacle information and driving status information of the vehicle transmitted by the automatic emergency braking system.

[0037] The obstacle information may specifically include: the distance between the vehicle and the obstacle, and the speed of the obstacle; the driving status information may specifically include: at least one of the vehicle's speed, acceleration, and steering angle. The automatic emergency braking system (AEBS) transmits the obstacle information and driving status information of the vehicle after detecting a potential hazard. Specifically, the AEBS collects obstacle information and driving status information of the vehicle in real time through sensors and / or radar. Upon detecting a potential hazard (such as an obstacle ahead), it immediately enters a warning state and transmits the detected hazard information to the central control unit in real time via an onboard communication network (such as a CAN bus).

[0038] Step S120: Based on the received obstacle information and driving status information of the vehicle, determine whether the vehicle has a collision risk.

[0039] In one specific implementation, the relative speed between the vehicle and the obstacle is calculated based on the speed of the vehicle and the speed of the obstacle; based on the distance between the vehicle and the obstacle and the relative speed between the vehicle and the obstacle, it is determined whether there is a potential collision risk to the vehicle.

[0040] Step S130: If it is determined that the vehicle has a potential collision risk, then control the electronically controlled air suspension system according to the type of obstacle, or control the automatic emergency braking system and the electronically controlled air suspension system according to the vehicle's driving conditions.

[0041] The types of obstacles can specifically include: small obstacles and large obstacles. Small obstacles are obstacles with a volume smaller than a preset volume; large obstacles are obstacles with a volume greater than or equal to a preset volume. Small obstacles can specifically include, for example, pedestrians and small vehicles; large obstacles can specifically include, for example, large vehicles.

[0042] In one specific implementation, if the obstacle is a small obstacle, the electronically controlled air suspension is controlled to lower a preset height; furthermore, the seat can also be adjusted to improve passenger safety.

[0043] For example, if a small obstacle (pedestrian, small vehicle, etc.) is identified as posing a potential collision risk, the central control unit will regulate ECAS (Electronic Stability Control System) to lower the suspension height, thereby lowering the vehicle's center of gravity and improving vehicle stability. Simultaneously, the central control unit can also adjust the seat to reduce head and neck movement for passengers, enhancing passenger safety. This includes tightening seatbelts and adjusting the seat height to ensure the driver is at a safe height. Airbags are in standby mode; if a collision is unavoidable, the airbags will deploy to further protect passengers. For example, Figure 2A schematic diagram illustrating the operation of suspension height adjustment is shown. The air suspension height is adjusted, for example, by raising or lowering the height by Δh.

[0044] In one specific implementation, if the obstacle is a large obstacle, the height of the electronically controlled air suspension is adjusted according to the obstacle's data. Specifically, the obstacle data may include the obstacle's height; if the obstacle's height reaches a first preset height, the electronically controlled air suspension is controlled to increase to a second preset height.

[0045] For example, if the obstacle is determined to be a large obstacle (such as a large vehicle) and poses a collision risk, the central control unit will control the electronically controlled air suspension (ECAS) to adjust the suspension height according to the obstacle's height. This prevents rear-end collisions from causing occupants to become trapped under the large vehicle and suffer secondary injuries, thus providing a certain level of protection. If a collision is unavoidable, the airbags will deploy to further protect passengers. For instance, if the obstacle is a large vehicle with a high profile, the vehicle's height will be adjusted to minimize damage after a collision.

[0046] In one specific embodiment, the driving condition includes: the vehicle traveling at a speed lower than a first preset speed threshold. When the vehicle is traveling at a speed lower than the first preset speed threshold, the automatic emergency braking system initiates braking in advance when it detects that the vehicle ahead is decelerating, and at the same time, the electronically controlled air suspension system controls the suspension to lower a preset height.

[0047] The vehicle travels at a speed below a first preset speed threshold, i.e., at a low speed, such as in low-speed following situations. The vehicle is moving slowly in traffic congestion or on urban roads at a low speed. LiDAR and cameras can model vehicles within a certain range, and the model data includes vehicle speed, number, and other information to determine whether there is traffic congestion or slow-moving traffic. Frequent starts and stops are required, placing high demands on the vehicle's comfort and stability. The Automatic Emergency Braking System (AEBS) detects vehicles ahead, maintains a safe distance, and avoids rear-end collisions. When it detects that a vehicle ahead is decelerating, AEBS initiates braking in advance, and simultaneously, the Electronic Air Suspension System (ECAS) adjusts the suspension, lowering the preset height and reducing the distance between the axle and the frame, optimizing the vehicle's dynamic response.

[0048] In another specific embodiment, the driving condition includes: the vehicle traveling at a speed higher than a second preset speed threshold. When the vehicle is traveling at a speed higher than the second preset speed threshold, if a potential collision risk is detected, the automatic emergency braking system immediately initiates braking, and simultaneously the electronically controlled air suspension system adjusts the suspension height and stiffness.

[0049] The vehicle travels at a speed exceeding a second preset speed threshold, i.e., at high speed. For example, when traveling at high speed, the vehicle detects obstacles ahead and quickly assesses the risk of collision. When a potential collision risk is detected, the Automatic Emergency Braking System (AEBS) immediately initiates braking, while the Electronic Air Suspension System (ECAS) adjusts the suspension height and stiffness. The suspension height is lowered by a third preset height to optimize the vehicle's center of gravity distribution, reducing pitch and roll during braking. The suspension stiffness is increased by a preset stiffness value to reduce roll and body sway at high speeds, improving vehicle handling; for example, the suspension stiffness is adjusted to 100-150 N / mm. Suspension stiffness can be adjusted by adjusting the stiffness of the shock absorbers. Depending on road conditions, a lower stiffness may be needed on bumpy roads to ensure comfort.

[0050] In another specific embodiment, the driving condition includes: the vehicle undergoing emergency braking due to a potential collision risk. When the automatic emergency braking system detects that the vehicle is undergoing emergency braking due to a potential collision risk, the electronically controlled air suspension system adjusts the suspension height and stiffness.

[0051] For example, upon detecting a potential collision risk, the braking system is immediately activated, and the hazard information is transmitted to the Electronically Controlled Air Suspension System (ECAS) via the vehicle communication network, initiating coordinated control. The suspension height is lowered by a third preset height, lowering the vehicle's center of gravity and improving vehicle stability. Simultaneously, the suspension stiffness is increased by a preset stiffness value, optimizing the vehicle's dynamic response during emergency braking.

[0052] In another specific embodiment, the driving condition includes: the vehicle driving on a curve. When the vehicle is detected driving on a curve, if a potential collision risk is detected, the automatic emergency braking system immediately initiates braking, and at the same time, the electronically controlled air suspension system adjusts the suspension height and stiffness according to the vehicle's turning angle and speed.

[0053] For example, in mountain road curves, when a vehicle is driving on a curve, the Automatic Emergency Braking System (AEBS) needs to detect obstacles ahead and activate the brakes when a collision risk is detected. At the same time, the Electronic Air Suspension System (ECAS) adjusts the suspension to reduce body roll and body sway. Based on the vehicle's turning angle and speed, it adjusts the suspension stiffness and height to optimize the vehicle's roll angle and improve handling.

[0054] Specifically, when the turning angle is greater than or equal to a preset angle and the speed reaches a preset speed, the lower side of the air suspension on both sides is raised to maintain balance between the left and right sides of the vehicle. The height of the suspension increase is, for example, the difference in height between the left and right sides. For instance, based on the real-time height value collected by the height sensor, if one side of the vehicle is lowered during a turn, and the value collected by the height sensor is lower, the ECAS executes a command to raise that side to balance it.

[0055] To clearly illustrate the technical solution of the present invention, the execution flow of the vehicle control method provided by the present invention will be described below with reference to a specific embodiment.

[0056] Figure 3 This is a schematic diagram of a specific embodiment of the vehicle control method provided by the present invention. Figure 3 As shown, AEBS detects the vehicle's status, and the central control unit receives the information detected by AEBS to determine whether there is a potential collision risk. If there is a potential collision risk, ECAS suspension adjustment, seat adjustment, and airbag standby are performed. If a collision is unavoidable, the airbags will deploy.

[0057] Figure 4 A schematic diagram of the module of the present invention is shown. For example... Figure 4 As shown, the system includes an AEBS module, a central control unit, an EACS module, and an occupant protection module. This invention provides a comprehensive occupant protection mechanism through the coordinated operation of the electronically controlled air suspension system (ECAS) and the automatic emergency braking system (AEBS), combined with the dynamic adjustment of the occupant protection module. This innovative protection mechanism not only enhances occupant safety but also optimizes vehicle dynamic performance and ride comfort.

[0058] This invention also provides a vehicle control device. The vehicle includes an electronically controlled air suspension system and an automatic emergency braking system. The electronically controlled air suspension system and the automatic emergency braking system are connected via an onboard communication network, enabling real-time data communication. For example, the electronically controlled air suspension system (ECAS) and the emergency braking system share real-time data via a CAN bus. The control method of this invention can be implemented in a vehicle controller. Specifically, it can be implemented in the central control unit of the vehicle controller.

[0059] Figure 5 This is a structural block diagram of an embodiment of the vehicle control device provided by the present invention. Figure 5 As shown, the vehicle control device 100 includes: a receiving unit 110, a judging unit 120, and a control unit 130.

[0060] The receiving unit 110 is used to receive obstacle information and driving status information of the vehicle transmitted by the automatic emergency braking system.

[0061] The obstacle information may specifically include: the distance between the vehicle and the obstacle, and the speed of the obstacle; the driving status information may specifically include: at least one of the vehicle's speed, acceleration, and steering angle. The automatic emergency braking system (AEBS) transmits the obstacle information and driving status information of the vehicle after detecting a potential hazard. Specifically, the AEBS collects obstacle information and driving status information of the vehicle in real time through sensors and / or radar. Upon detecting a potential hazard (such as an obstacle ahead), it immediately enters a warning state and transmits the detected hazard information to the central control unit in real time via an onboard communication network (such as a CAN bus).

[0062] The judgment unit 120 is used to determine whether the vehicle has a potential collision risk based on the obstacle information and driving status information of the vehicle received by the receiving unit.

[0063] In one specific implementation, the relative speed between the vehicle and the obstacle is calculated based on the speed of the vehicle and the speed of the obstacle; based on the distance between the vehicle and the obstacle and the relative speed between the vehicle and the obstacle, it is determined whether there is a potential collision risk to the vehicle.

[0064] The control unit 130 is configured to control the electronically controlled air suspension system according to the type of obstacle if the judgment unit 120 determines that the vehicle has a potential collision risk, or to control the automatic emergency braking system and the electronically controlled air suspension system according to the driving conditions of the vehicle.

[0065] The types of obstacles can specifically include: small obstacles and large obstacles. Small obstacles are obstacles with a volume smaller than a preset volume; large obstacles are obstacles with a volume greater than or equal to a preset volume. Small obstacles can specifically include, for example, pedestrians and small vehicles; large obstacles can specifically include, for example, large vehicles.

[0066] In one specific implementation, if the obstacle is a small obstacle, the electronically controlled air suspension is controlled to lower a preset height; furthermore, the seat can also be adjusted to improve passenger safety.

[0067] For example, if a small obstacle (pedestrian, small vehicle, etc.) is identified as posing a potential collision risk, the central control unit will activate ECAS to lower the suspension height, thereby lowering the vehicle's center of gravity and improving vehicle stability. Simultaneously, the central control unit can also make safety adjustments to the seat to reduce head and neck movement for passengers, enhancing passenger safety. For example, it can tighten seatbelts and adjust the seat height to ensure the driver is at a safe height. The airbags are in standby mode; if a collision is unavoidable, the airbags will deploy to further protect passengers.

[0068] In one specific implementation, if the obstacle is a large obstacle, the height of the electronically controlled air suspension is adjusted according to the obstacle's data. Specifically, the obstacle data may include the obstacle's height; if the obstacle's height reaches a first preset height, the electronically controlled air suspension is controlled to increase to a second preset height.

[0069] For example, if the obstacle is determined to be a large obstacle (such as a large vehicle) and poses a collision risk, the central control unit will control the electronically controlled air suspension (ECAS) to adjust the suspension height according to the obstacle's height. This prevents rear-end collisions from causing occupants to become trapped under the large vehicle and suffer secondary injuries, thus providing a certain level of protection. If a collision is unavoidable, the airbags will deploy to further protect passengers. For instance, if the obstacle is a large vehicle with a high profile, the vehicle's height will be adjusted to minimize damage after a collision.

[0070] In one specific embodiment, the driving condition includes: the vehicle traveling at a speed lower than a first preset speed threshold. When the vehicle is traveling at a speed lower than the first preset speed threshold, the automatic emergency braking system initiates braking in advance when it detects that the vehicle ahead is decelerating, and at the same time, the electronically controlled air suspension system controls the suspension to lower a preset height.

[0071] The vehicle travels at a speed below a first preset speed threshold, i.e., at a low speed, such as in low-speed following situations. The vehicle is moving slowly in traffic congestion or on urban roads at a low speed. LiDAR and cameras can model vehicles within a certain range, and the model data includes vehicle speed, number, and other information to determine whether there is traffic congestion or slow-moving traffic. Frequent starts and stops are required, placing high demands on the vehicle's comfort and stability. The Automatic Emergency Braking System (AEBS) detects vehicles ahead, maintains a safe distance, and avoids rear-end collisions. When it detects that a vehicle ahead is decelerating, AEBS initiates braking in advance, and simultaneously, the Electronic Air Suspension System (ECAS) adjusts the suspension, lowering the preset height and reducing the distance between the axle and the frame, optimizing the vehicle's dynamic response.

[0072] In another specific embodiment, the driving condition includes: the vehicle traveling at a speed higher than a second preset speed threshold. When the vehicle is traveling at a speed higher than the second preset speed threshold, if a potential collision risk is detected, the automatic emergency braking system immediately initiates braking, and simultaneously the electronically controlled air suspension system adjusts the suspension height and stiffness.

[0073] The vehicle travels at a speed exceeding a second preset speed threshold, i.e., at high speed. For example, when traveling at high speed, the vehicle detects obstacles ahead and quickly assesses the risk of collision. When a potential collision risk is detected, the Automatic Emergency Braking System (AEBS) immediately initiates braking, while the Electronic Air Suspension System (ECAS) adjusts the suspension height and stiffness. The suspension height is lowered by a third preset height to optimize the vehicle's center of gravity distribution, reducing pitch and roll during braking. The suspension stiffness is increased by a preset stiffness value to reduce roll and body sway at high speeds, improving vehicle handling. For example, the suspension stiffness is adjusted to 100-150 N / mm. Suspension stiffness can be adjusted by adjusting the stiffness of the shock absorbers. Depending on road conditions, a lower stiffness may be needed on bumpy roads to ensure comfort.

[0074] In another specific embodiment, the driving condition includes: the vehicle undergoing emergency braking due to a potential collision risk. When the automatic emergency braking system detects that the vehicle is undergoing emergency braking due to a potential collision risk, the electronically controlled air suspension system adjusts the suspension height and stiffness.

[0075] For example, upon detecting a potential collision risk, the braking system is immediately activated, and the hazard information is transmitted to the electronically controlled air suspension system (ECAS) via the vehicle communication network, initiating coordinated control. The suspension height is rapidly reduced to a third preset height, lowering the vehicle's center of gravity and improving stability. Simultaneously, the suspension stiffness is increased to a preset value, optimizing the vehicle's dynamic response during emergency braking.

[0076] In another specific embodiment, the driving condition includes: the vehicle driving on a curve. When the vehicle is detected driving on a curve, if a potential collision risk is detected, the automatic emergency braking system immediately initiates braking, and at the same time, the electronically controlled air suspension system adjusts the suspension height and stiffness according to the vehicle's turning angle and speed.

[0077] For example, in mountain road curves, when a vehicle is driving on a curve, the Automatic Emergency Braking System (AEBS) needs to detect obstacles ahead and activate the brakes when a collision risk is detected. Simultaneously, the Electronically Controlled Air Suspension System (ECAS) adjusts the suspension to reduce roll and body sway. Based on the vehicle's turning angle and speed, it adjusts the suspension stiffness and height to optimize the vehicle's roll angle and improve handling. Specifically, when the turning angle is greater than or equal to a preset angle and the speed reaches a preset speed, the lower side of the left and right air suspensions is raised to maintain balance. The height increase is, for example, the difference in height between the left and right sides. For instance, based on real-time height values ​​collected by height sensors, if one side of the vehicle is lowered during a turn, and the height sensor reading is lower, ECAS executes a raise command on that side to balance it.

[0078] The present invention also provides a storage medium corresponding to the control method of the vehicle, wherein a computer program is stored thereon, which, when executed by a processor, implements the steps of any of the aforementioned methods.

[0079] The present invention also provides a vehicle controller corresponding to the control method of the vehicle, including a processor, a memory, and a computer program stored in the memory that can run on the processor, wherein the processor executes the computer program to implement the steps of any of the aforementioned methods.

[0080] The present invention also provides a vehicle controller corresponding to the control device of the vehicle, including the control device of any of the aforementioned vehicles.

[0081] The present invention also provides a computer program product corresponding to the control method of the vehicle, including a computer program that, when executed by a processor, implements the steps of any of the aforementioned methods.

[0082] Accordingly, the solution provided by this invention, through the coordinated operation of the Electronically Controlled Air Suspension System (ECAS) and the Automatic Emergency Braking System (AEBS), can more effectively protect occupants in emergency situations. When the AEBS triggers emergency braking, the ECAS can quickly adjust the suspension height and stiffness, lower the vehicle's center of gravity, reduce head and body sway during emergency braking or a collision, improve vehicle stability, and thus reduce the risk of injury. Furthermore, measures such as seat adjustment can optimize the occupant's posture and reduce the impact force during a collision.
