PURPOSE: A starting safety device and control method automatically operates brake system of a car and intercepts the operation of an engine when an automatic transmission is of abnormal condition on starting to improve safety of the car. CONSTITUTION: A method comprises five steps. The first step is to advance an actuator connected with a brake system when a starting switch of a car is turned on(S1, S2). The second step is to detect idling condition of an engine, position of a selector lever and actual pressure condition of various equipment in an automatic transmission(S3, S4, S5). The third step is to determine whether a car is of idling condition(S6). The fourth step is to determine whether the actual pressure in the automatic transmission is within normal range if the car is determined to be of idling condition(S7). The fifth step is to intercept electric power supplied to an injector of the engine if the actual pressure in the automatic transmission is determined to be out of normal range. |
