ABSTRACT:
Temperature of brake fluid is estimated, and a pressure-increase gradient change ratio Pup, a pressure-reduction gradient change ratio Pdw, and pump-discharge gradient change quantity Ppmp in correspondence with an amount of decline in pump-discharge capacity at the estimated brake-fluid temperature are calculated respectively. These compensation multipliers Pup, Pdw, and Ppmp are variables for obtaining a pressure-increase gradient change ratio, pressure-reduction gradient change ratio, and pump-discharge gradient change quantity identical to a time of normal temperature (i.e., a time of normal temperature when pump-discharge capacity has not declined). Accordingly, a pressure-increase time Tup and pressure-reduction time Tdw in ABS control and TRC control are calculated utilizing these compensation multipliers to obtain control performance of brake-fluid pressure similar to a time of normal temperature.
