ABSTRACT:
A deceleration control device for a vehicle receives signals from an acceleration sensor, a speed sensor, and a brake fluid pressure sensor to calculate a brake fluid pressure control value to output a control signal to a brake pressure fluid control device. The deceleration control device may include a first arithmetic unit for calculating an actual deceleration of the vehicle, a second arithmetic unit for calculating a speed of the vehicle, a third arithmetic unit for calculating a target deceleration, and a fourth arithmetic unit for calculating the brake fluid pressure control command value. The first arithmetic unit may be coupled to the acceleration sensor signal and the speed sensor signal, the second arithmetic unit may be coupled to either the speed sensor signal or output of the first arithmetic unit, and the third arithmetic unit may be coupled to receive signals indicative of a stepping force of a brake pedal or a distance between the vehicle and an obstacle.
