PURPOSE: A deceleration controlling device is provided to keep deceleration accurately with adjusting brake fluid pressure applying to a wheel cylinder by comparing detected deceleration with the reference value, and to improve reliability by testing conveniently. CONSTITUTION: A deceleration controller is composed of an operating unit(21) deciding deceleration of a vehicle; a sensor(22) detecting reduction speed; a brake switch(23) detecting operation of a brake pedal; a control unit(24) comparing the designated deceleration with the deceleration detected by the sensor in operating the brake pedal for a traveling test, and regulating brake fluid pressure applying to a wheel cylinder to identify the designated deceleration with the detected deceleration; and a driving unit(26) actuating a solenoid valve installed in the wheel cylinder. Noise from a brake system is inspected conveniently with designating the deceleration by inputting a key, and checking by a passenger. The reliability is improved with detecting noise accurately according to deceleration.
