BRAKING CONTROL SYSTEM AND METHOD FOR VEHICLE
A braking control system and method for a vehicle are configured to calculate a braking force of front and rear wheels using a wheel slip ratio of the front and rear wheels and a road surface friction coefficient and then accurately estimate and calculate a disk temperature of the front and rear wheels using a predetermined estimation formula from the calculated braking force, and control distribution of braking pressure to the front wheels and the rear wheels so as to uniformly wear brake pads based on the calculated temperatures of the disks.
Standstill management yaw mitigation on low mu grades
A stability control system of a vehicle utilizing an electronic control unit that detects a yaw condition while each of the wheel brakes are actuated by EBCM and the wheel speeds are zero. An electronic control unit includes an electronic braking control module that controls actuation and de-actuation of vehicle brakes on an inclined surface. A yaw condition is identified while all vehicle brakes are actuated on the inclined surface and each wheel speed is zero. The electronic control unit identifies which uphill wheel is leading a direction of the yaw and identifies a wheel of an opposing axle diagonal to the identified uphill wheel. The electronic control unit in cooperation with the electronic braking control module de-actuates the vehicle brakes of the identified uphill wheel and diagonal wheel to increase a side friction to the identified diagonal wheels to reduce further yawing of the vehicle.
