METHOD OF BRAKING AUTONOMOUS VEHICLE ON SLOPE AND AUTONOMOUS VEHICLE

Provided is a method of braking an autonomous vehicle stopped on a sloped surface. The method includes detecting a roll down of the first vehicle that stopped while adaptive cruise control of the first vehicle is engaged. Detecting the roll down is based on: whether the first vehicle stops on an uphill slope; whether a distance to a second vehicle in front of the first vehicle increases; whether a signal of a wheel sensor of the first vehicle is detected; and/or whether an absolute value of a negative motor speed of the first vehicle increases and whether the signal of the wheel sensor indicates a rearward movement of the first vehicle. The method further includes: determining, based on the detecting of the roll down of the first vehicle, a braking pressure for the first vehicle; and controlling the first vehicle to brake according to the determined braking pressure.
