Abstract

The invention discloses a vehicle body balance control method. The method comprises the steps: acquiring driving speed information and corner information of a vehicle and a road surface image of the vehicle in the current driving direction; determining target object position data and target object state information of a target object of the vehicle in the current driving direction according to the road surface image; according to the driving speed information, the turning angle information and the target object position data, predicting the starting time of vibration of the vehicle; determining the suspension height control quantity of each wheel according to the target object state information; and sending the starting time when the vehicle vibrates and the suspension height control quantity of each wheel to a suspension system. According to the scheme, before the vehicle vibrates due to the target object, the control strategy comprising the starting time of vehicle vibration and the corresponding suspension height control quantity is determined in advance according to the target object information of the front road surface, so that active shock absorption in the true sense is realized.

Description

technical field [0001] The present application relates to the technical field of vehicle control, in particular to a vehicle and its body balance control method and control system. Background technique [0002] The active suspension in modern cars is a new type of suspension developed in recent decades. Its control principle is: when the car brakes or turns, the sensors in the suspension system transmit information such as vehicle speed and vertical vibration of the vehicle body to the electronic system. The control unit ECU, ECU sends control commands according to the input signal and the preset control program, controls the servo motor and manipulates the front and rear four executive cylinders to make the hydraulic suspension or other forms of suspension generate a force against the inertial force , to control body vibration and body height. This control method is only after the vibration occurs, the sensors on the suspension system collect signals such as the wheel beat...
