To provide a deceleration controller for a vehicle capable of responding to various situations and providing a high deceleration transient characteristic of the vehicle.
A braking force generated by a braking device is controlled so that a target deceleration is acted on the vehicle, based on the target deceleration 403 set as the deceleration to be acted on the vehicle by an operation of the braking device 200 for generating a braking force in the vehicle and a shift operation shifting a transmission 10 of the vehicle to a gear stage or gear ratio of relatively low speed, and based on a deceleration by the shift operation to the gear stage or gear ratio selected as the shift operation to the gear stage or gear ratio adapting to the target deceleration. When the target deceleration is set and the gear stage or gear ratio adapting to the target deceleration is selected, the braking device is controlled on a real time basis so that the difference between the deceleration by the gear shift to the gear stage or gear ratio and the target deceleration is compensated, the whole cooperative control of the braking device and the transmission is acted, and resultingly the target deceleration acts on the vehicle.
