1. A control method for a hill start assistant control system which prevents a vehicle from being pushed back by generating a braking force with a brake system when the vehicle starts after stopping on a hill, the method comprising:
(a) determining, by a controller, that the vehicle is stopped and braked; (b) receiving, by the controller, a current sensing value from an acceleration sensor on the vehicle which senses acceleration and periodically outputs a sensing value with the vehicle stopped and braked; (c) determining, by the controller, whether a condition for stabilizing an output of the acceleration sensor is satisfied, using the current sensing value and a previous sensing value; (d) finding an acceleration accumulation average, by the controller, by accumulating the current sensing value and averaging sensing values of the acceleration sensor which are accumulated up to a current time when the condition for stabilizing the output of the acceleration sensor is not satisfied; (e) comparing the acceleration accumulation average with an accumulation reference value, by the controller; and (f) operating the hill start assistant control system, by the controller, when the acceleration accumulation average is larger than the acceleration reference value. |
