  • Patent number: 6212462
    Abstract: An automotive brake control system with an ABS system employing a hydraulic modulator, wheel-speed sensors, a longitudinal acceleration sensor, and a skid control unit. The skid control unit includes a lateral acceleration dependent offset-value arithmetic-calculation section which arithmetically calculates an offset value based on lateral acceleration exerted on the vehicle. Also provided is a pseudo-vehicle-speed compensation section which decreasingly compensates for a pseudo vehicle speed (an estimated vehicle speed value) by compensating for a signal value of input information data from the longitudinal acceleration sensor by the offset value based on the lateral acceleration exerted on the vehicle owing to the turn, when the vehicle is decelerating.
