Abstract
The present invention pertains a controlling scheme for build-up or variation rate at which brake pressure increases till completion of pressure build-up for stand-by brake torque. Stand-by brake torque control begins with recognition of emergency or occurrence of operator reaction or quick release of accelerator. During initial stage of the stand-by brake control, brake pressure increases till completion of pressure build-up for stand-by brake torque before vehicle operator depresses a brake pedal. Build-up or variation rate at which brake pressure increases till completion of pressure build-up for stand-by brake torque is determined in response to time left before the operator depresses the brake pedal. Period of time left before the operator depresses the brake pedal varies with differing events that have initiated the stand-by brake torque control.
