Embodiment Construction

[0043] The technical scheme of the present invention calculates the optimized heights of the front suspension and the rear suspension respectively during the automatic emergency braking process of the vehicle, and simultaneously adjusts the heights of the front suspension and the rear suspension according to the calculated optimal height until the height variation of the two Until the same, the pitching motion of the vehicle during the automatic emergency braking process is slowed down or suppressed. Moreover, the technical solution of the present invention also provides a target braking force for the vehicle during automatic emergency braking of the vehicle, thereby improving braking efficiency.

[0044] Various embodiments of the present invention are described below with reference to the accompanying drawings.

[0045] figure 1 A stability system 100 for a vehicle according to a possible embodiment of the present invention is shown, which mainly includes a sensor unit 10 ,...

Abstract

A stability system for a vehicle, and a control unit and method thereof are provided. The control unit (21) comprises: an acquisition module (31) configured to acquire the distance between the front suspension and the center of mass of the vehicle and the distance between the rear suspension and the center of mass of the vehicle; a processing module (32) which is configured to calculate the optimized height of the front suspension based on the static vertical load and the maximum vertical load of the front suspension and the actual friction coefficient, and calculate the optimized height of the rear suspension based on the static vertical load and the maximum vertical load of the rear suspension and the actual friction coefficient; and a generation module (33) configured to generate a first height control signal according to the optimized height of the front suspension; and generate a second height control signal according to the optimized height of the rear suspension.

Description

technical field [0001] The invention relates to a stability system for a vehicle and its control unit and method. Background technique [0002] The vehicle's stability system can improve the vehicle's handling performance and can effectively prevent the car from losing control when it reaches its dynamic limit. Because the stability system of the vehicle can improve the safety and handling of the vehicle. The vehicle's stability system can actively improve safety in various scenarios. For example, during automatic emergency braking (AEB), the vehicle's stability system can improve safety and handling by controlling the suspension system. [0003] The suspension system of the vehicle is used to transmit force and moment between the wheel and the axle, suppress the vibration of the vehicle during driving, and ensure the smooth running of the vehicle. During braking, the vehicle exhibits instabilities such as pitching motions, which have a negative impact on vehicle stabilit...
