APPARATUS FOR PREVENTING SUDDEN START OF MOTOR VEHICLE WITH AUTOMATIC TRANSMISSION AND METHOD OF CONTROLLING PREVENTIVE OPERATION AGAINST SUDDEN START

摘要

PURPOSE: An apparatus and method is provided to prevent accident caused by a sudden start of vehicle by automatically stopping the operation of engine when the current state of a vehicle has a likelihood of sudden start. CONSTITUTION: An apparatus comprises an air suction open/shut-off unit disposed in the air suction system of an engine; and an operation control unit for collecting information related to the rotation speed of a driving wheel and a slave wheel and starting operation of vehicle, so that a shutter down control unit selectively operates the air suction open/shut-off unit. A method comprises the first step(S11) of judging whether an operation selection switch is "on"; the second step(S12,S13) of receiving information regarding rotational frequency of wheels from a wheel sensor, if it is judged in the first step that the switch is on; the third step(S14) of judging whether the difference between the rotational frequency(A) of the driving wheel and the rotational frequency(B) of the slave wheel is larger than the reference(X); the fourth step(S15) of judging whether the actual vehicle speed(Q) is larger than B, if it is judged in the third step that (A-B) is larger than the reference; and the fifth step(S16) of allowing the shutter down control unit to operate an actuator of the shutter down valve so as to shut off a valve plate, thereby shutting off the air being supplied to the air suction system, if it is judged in the fourth step that the actual vehicle speed is larger than B.
