Abstract
A vehicle dynamics control system for an automotive vehicle with a diagonal split layout of brake circuits comprises a tandem master cylinder, two hydraulic pumps each fluidly disposed in one of the two brake circuits, selector valves for selecting a brake-fluid pressure to be fed to a first brake line and for selecting a brake-fluid pressure to be fed to a second brake line, 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 valves. 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.
