Embodiment Construction

[0048] figure 1 is a flowchart of a chassis control method according to an embodiment of the present invention. In one embodiment, such as figure 1 As shown, the chassis control method includes:

[0049] Step S10, collecting information about operating parameters of the vehicle. The collection process can be to obtain the information collected by the sensor, or to obtain relevant information from the CAN bus of the vehicle, for example, the driving mode information of the vehicle can be obtained from the CAN bus.

[0050] In step S20, each control model is used to determine the corresponding required yaw torque according to the required operating parameter information, and each control model corresponds to each preset operating condition.

[0051]Step S30, calculating the total required yaw torque of the vehicle according to each required yaw torque.

[0052] Step S40, acquiring the current yaw torque execution capability of each actuator of the vehicle.

[0053] In step ...

Abstract

The invention provides a chassis control method and a chassis control system, and belongs to the field of vehicle chassis control. The chassis control method comprises the steps of collecting operation parameter information of a vehicle; determining a corresponding required yaw torque according to the required operation parameter information through each control model, wherein each control model corresponds to each preset use condition; calculating the total required yaw torque of the vehicle according to all the required yaw torques; acquiring the current yaw torque execution capability of each actuator of the vehicle; and according to the total required yaw torque, the current yaw torque execution capability of each actuator and a preset distribution rule, determining a target yaw torque of each actuator, so that each actuator outputs the corresponding target yaw torque. The invention further provides a chassis control system corresponding to the chassis control method. According to the chassis control method and system, the stability and safety of the vehicle can be guaranteed.

Description

technical field [0001] The invention belongs to the field of vehicle chassis control, in particular to a chassis control method and a chassis control system. Background technique [0002] With the rapid development of the automobile industry, the chassis field is electrified and the degree of electronic control is getting higher and higher. Key performance parts have electronic control functions, such as braking stability systems, electronic steering systems, active stabilizer bars, and air suspensions. , rear wheel steering, etc. The popularization of chassis electronic control can bring consumers a safer, more stable and more agile driving experience, and greatly improve the handling performance of the vehicle. [0003] However, different chassis controllers or power systems can have a positive impact on lateral stability to some extent, which brings great difficulties for matching calibration and product development.
