Abstract
A vehicle dynamics control system for an automotive vehicle with a parallel split layout of brake circuits comprises a tandem master cylinder, a hydraulic pump fluidly disposed in one brake circuit, a selector valve for selecting a brake-fluid pressure to be fed to a first brake line from between the fluid pressure generated from the pump and the master-cylinder pressure, a plurality of pressure control valves for regulating a fluid pressure in each individual wheel-brake cylinder, vehicle sensors for detecting a vehicle's cornering behavior, and a control unit being responsive to the sensor's input information for controlling the respective control valves associated with the front wheel-brake cylinders. The control unit operates to supply the fluid pressure generated from the pump to an inner front wheel-brake cylinder in the vehicle understeer on turns. The control unit also operates to supply the fluid pressure generated from the pump to an outer front wheel-brake cylinder in the vehicle oversteer on turns.
