[0043] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] In the description of one or more embodiments of the present invention, the term "including" and similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0045] See also Figure 1 , is a schematic flow chart of a launch control method provided by an embodiment of the present invention. The execution subject of the process may be a program for vehicle launch control, or the execution subject of the process may also be a vehicle or a domain controller equipped with the above program, or other devices capable of communicating with a vehicle, a domain controller, etc., which are not specifically limited.

[0046] The following is for Figure 1 The process shown in the figure is described in detail, and the launch control method may specifically include the following steps:

[0047] Step S102, receiving a user's instruction to start the launch mode, and adjusting the vehicle suspension height to a target height based on the instruction;

[0048] For vehicles equipped with the launch mode, the user can generate an activation instruction corresponding to the launch mode by triggering a mode control for activating the launch mode. When the program for vehicle launch control detects the activation instruction corresponding to the launch mode, the suspension system is controlled according to the activation instruction to adjust the vehicle suspension height to the target height.

[0049] Among them, the vehicle suspension height can be adjusted to a target height based on the air spring in the suspension system.

[0050] Optionally, the target height may be a minimum suspension height. It is not difficult to understand that by adjusting the suspension height to the target height, the vehicle can obtain a stronger grip, thereby improving the acceleration effect of the vehicle during launch.

[0051] Further optionally, adjusting the vehicle suspension height to the target height based on the start instruction may be: adjusting the front axle suspension height of the vehicle to a first target height, and adjusting the rear axle suspension height of the vehicle to a second target height; wherein the first target height is less than the second target height.

[0052] Step S104, after adjusting the vehicle suspension height to the target height, controlling the vehicle to launch based on the user's acceleration instruction to the vehicle.

[0053] Specifically, after adjusting the vehicle suspension height to the target height, based on the user's acceleration instruction for the vehicle, the vehicle is controlled to launch through the traction control system.

[0054] Traction Control System (TCS), also known as ASR or TRC, is an electronic control system designed to ensure that the car has the best traction during driving. TCS prevents excessive wheel slip by monitoring wheel slip and taking corresponding control measures, thereby ensuring that the car maintains stable traction under various road conditions.

[0055] In an embodiment of the present invention, in response to receiving a user's instruction to start the launch mode, the vehicle suspension height is adjusted to a target height based on the instruction to start, and after the vehicle suspension height is adjusted to the target height, the vehicle launch is controlled based on the user's acceleration instruction to the vehicle, that is, when the vehicle is in the launch start mode and before the launch start, the vehicle suspension height is adjusted to the target height to enable the vehicle to obtain stronger grip, thereby improving the acceleration effect of the vehicle during the launch start.

[0056] See also Figure 2 , is a schematic flow chart of a launch control method provided by an embodiment of the present invention. The execution subject of the process may be a program for vehicle launch control, or the execution subject of the process may also be a vehicle or a domain controller equipped with the above program, or other devices capable of communicating with a vehicle, a domain controller, etc., which are not specifically limited.

[0057] The following is for Figure 2 The process shown in the figure is described in detail, and the launch control method may specifically include the following steps:

[0058] Step S202, receiving a user's instruction to start the launch mode;

[0059] Specifically, for a vehicle equipped with the launch start mode, a user may generate an activation instruction corresponding to the launch start mode by triggering a mode control for activating the launch start mode, and a program for vehicle launch start control receives the activation instruction corresponding to the launch start mode.

[0060] Step S204, adjusting the front axle suspension height of the vehicle to a first target height, and adjusting the rear axle suspension height of the vehicle to a second target height based on the start instruction;

[0061] Specifically, when an activation instruction corresponding to the launch start mode is detected, the suspension system is controlled to adjust the vehicle suspension height according to the activation instruction, specifically adjusting the front axle suspension height of the vehicle to a first target height, and adjusting the rear axle suspension height of the vehicle to a second target height. The first target height is less than the second target height.

[0062] Preferably, the first target height may be 35 mm lower than the standard height of the air spring, and the second target height may be 15 mm lower than the standard height of the air spring. The standard height refers to the original suspension height calibrated by the developer, and the vehicle suspension may be lower than or higher than the original suspension height by adjusting the air spring.

[0063] It can be understood that by adjusting the front axle suspension height to be lower than the rear axle suspension height, the vehicle posture is optimized, wind resistance is reduced, and the front axle of the vehicle bears more sprung mass, so as to enhance the vehicle's grip during launch and improve the starting acceleration effect.

[0064] Step S206, increasing the spring stiffness of the air spring in the suspension system based on the start instruction;

[0065] Specifically, when an activation instruction corresponding to the launch start mode is detected, the spring stiffness of the air spring in the suspension system is increased according to the activation instruction.

[0066] It is not difficult to understand that by increasing the spring stiffness, the suspension system's support for the vehicle body can be enhanced. In this way, the changes in the vehicle body's posture during acceleration (such as the head-up phenomenon) will be better controlled, which will help maintain the stability and balance of the vehicle body, allowing the vehicle to better maintain grip and improve acceleration effects.

[0067] Optionally, the air spring is a multi-chamber air spring. Increasing the spring stiffness of the air spring in the suspension system can be achieved by closing a multi-chamber solenoid valve in the multi-chamber air spring.

[0068] Step S208, increasing the damping of the shock absorber in the suspension system based on the start instruction;

[0069] Specifically, when an activation instruction corresponding to the launch start mode is detected, the damping of the shock absorber in the suspension system is increased according to the activation instruction.

[0070] It is not difficult to understand that increasing the spring stiffness can help improve vehicle stability and optimize tire grip, thereby indirectly optimizing the vehicle's performance during acceleration and enhancing the launch-start acceleration effect.

[0071] Optionally, increasing the damping of a shock absorber in the suspension system may include adjusting the damping of each shock absorber in the vehicle to a maximum value.

[0072] Furthermore, in practical applications, due to the characteristics of front axle rebound and rear axle compression when the vehicle starts, the target damping values ​​after adjustment of the front axle and rear axle can be calibrated based on actual conditions.

[0073] Step S210, controlling the vehicle to launch based on the user's acceleration instruction to the vehicle.

[0074] Specifically, after executing step S204, step S206, and step S208, the vehicle completes the adjustment of the suspension, and then based on the user's acceleration instruction to the vehicle, the vehicle is controlled to launch through the traction control system.

[0075] It is further explained that before the launch, the user can increase the vehicle output torque at the moment of the launch by pressing the accelerator pedal and the brake pedal at the same time. If the accelerator pedal and the brake pedal of the vehicle are in a pressed state before the launch, after the suspension system adjustment is completed, the user can generate the acceleration command by releasing the brake pedal, and then the traction control system controls the launch of the vehicle. If the accelerator pedal and the brake pedal of the vehicle are not pressed before the launch, the user's acceleration command to the vehicle can be generated based on the user pressing the accelerator pedal, and then the traction control system controls the launch of the vehicle.

[0076] In an embodiment of the present invention, when the vehicle is in the launch start mode and before the vehicle is launched, the suspension is adjusted in terms of suspension height, suspension stiffness and suspension damping, so that the vehicle obtains stronger grip during the launch start and improves the vehicle launch start acceleration effect.

[0077] It should be noted that the suspension adjustment method in the launch mode proposed in the embodiments of the present invention can be flexibly set according to needs or actual hardware conditions. For example, when the vehicle does not have an electromagnetic shock absorber, the vehicle may not be damped, and only the suspension height and stiffness of the vehicle may be adjusted. One or more embodiments of the present invention do not specifically limit the number of vehicle suspension adjustment methods in the launch mode.

[0078] See also Figure 3, is a schematic flow chart of a launch control method provided by an embodiment of the present invention. The execution subject of the process may be a program for vehicle launch control, or the execution subject of the process may also be a vehicle or a domain controller equipped with the above program, or other devices capable of communicating with a vehicle, a domain controller, etc., which are not specifically limited.

[0079] The following is for Figure 3 The process shown in the figure is described in detail, and the launch control method may specifically include the following steps:

[0080] Step S302, receiving a user's instruction to start the launch mode;

[0081] Specifically, for step S302, please refer to the detailed description of step S202 in another embodiment of the present invention, which will not be repeated here.

[0082] Step S304, adjusting the front axle suspension height of the vehicle to a first target height, and adjusting the rear axle suspension height of the vehicle to a second target height based on the start instruction;

[0083] Specifically, for step S304, please refer to the detailed description of step S204 in another embodiment of the present invention, which will not be repeated here.

[0084] It can be understood that by adjusting the front axle suspension height to be lower than the rear axle suspension height, the front axle of the vehicle bears more sprung mass to enhance the vehicle's grip during launch, thereby improving the starting acceleration effect.

[0085] Step S306, increasing the spring stiffness of the air spring in the suspension system based on the start instruction;

[0086] Specifically, for step S306, please refer to the detailed description of step S206 in another embodiment of the present invention, which will not be repeated here.

[0087] Step S308, increasing the damping of the shock absorber in the suspension system based on the start instruction;

[0088] Specifically, for step S308, please refer to the detailed description of step S208 in another embodiment of the present invention, which will not be repeated here.

[0089] Step S310, obtaining the height and pressure corresponding to each air spring in the suspension system;

[0090] Specifically, after executing the above steps and adjusting the suspension height, spring stiffness, and shock absorber damping respectively, the height and air chamber pressure corresponding to each air spring in the suspension system are measured in real time based on the height sensor and pressure sensor arranged in the air spring.

[0091] Step S312, calculating the sprung mass corresponding to each air spring based on the height and pressure corresponding to each air spring;

[0092] Specifically, after obtaining the height and pressure corresponding to each air spring, the sprung mass corresponding to each air spring is determined according to the height and pressure corresponding to each air spring according to a pre-calibrated mapping relationship, wherein the height is the current height of the air spring, and the pressure is the current pressure in the air chamber of the air spring.

[0093] Step S314, adjusting the vehicle dynamics model based on the sprung masses corresponding to the air springs;

[0094] Step S316, controlling the vehicle launch based on the adjusted dynamics model combined with the maximum friction coefficient estimation method and the slip ratio optimization technology.

[0095] Specifically, after calculating the sprung mass corresponding to each air spring, the sprung mass corresponding to each air spring is sent to the traction control system, so that the traction control system adjusts the vehicle dynamics model according to the sprung mass corresponding to each air spring, and then controls the vehicle launch based on the adjusted dynamics model combined with the maximum friction coefficient estimation method and the slip rate optimization technology. The maximum friction coefficient estimation helps the system to more accurately determine the adhesion between the wheel and the road surface, thereby more effectively controlling the wheel slip. The slip rate optimization technology optimizes the slip rate to control the wheel slip, which can improve the vehicle's traction performance and driving stability.

[0096] It is not difficult to understand that by adjusting the vehicle dynamics model according to the sprung mass corresponding to each wheel end after adjusting the suspension, the traction control system can more accurately calculate the friction coefficient between the tire and the road, thereby better adjusting the slip rate of the vehicle, thereby improving the vehicle's traction performance and the acceleration effect of the launch control.

[0097] Furthermore, during the launch control of the vehicle by the traction control system, the suspension system can be controlled and adjusted based on the ground hook suspension control algorithm to enable the vehicle to obtain stronger grip, thereby obtaining a better acceleration effect.
