<p>The present invention provides an apparatus and method of automatically braking a vehicle in a stop state by using a signal of a vehicle-speed sensor in a vehicle, and can be used as an alternative to a parking brake. A stop signal conversion means (20), an accelerator pedal sensing means (40), a stopping/running judgement means (50), a switch means (60) and an electromagnetically operated switching valve (70) are comprised. One of a high-level signal and a low-level signal from the vehicle-speed sensor (10) in the stop state of the vehicle by pressing the brake pedal is detected as it is, and the other one of a high-level signal and a low-level signal from the vehicle-speed sensor (10) is converted by a stop signal conversion means (20) and detecting the converted one. A brake line (L) is closed and the vehicle is braked by detecting the stop state using a single signal from the vehicle-speed sensor (10) although the pressing of the brake pedal may be released.</p> |
