Abstract
In the case that a brake controller is installed to a 4 wheel driven vehicle, braking force control should be carried out effectively enough so that running stability of the vehicle can be up-graded at cornering. The brake controller,calculates differential value of aimed yaw rate, differential value of predicted yaw rate on low friction road and deflection of the two differential values. And also it calculates deflection of real yaw rate and aimed yaw rate. Then the brake controller,determines aimed braking force and applies the aimed braking force to a selected wheel to carry out braking control. The torque distribution controller,receives control parameters and signals of status of brake control and carries out torque distribution control based on the parameters and signals through the hydraulic multi-plate clutch,The hydraulic multi-plate clutch,is so controlled with certain weak engaging force as to make each wheel rotate freely, when braking control is carried out by applying braking force to a selected wheel. Thus the brake controller,can perform as aimed.
