SMART ENTRY SYSTEM FOR VEHICLE

PROBLEM TO BE SOLVED: To provide a technology capable of suppressing a wrong decision on the existence of a disturbing wave by making the detection of the existence of the disturbing wave in the outside of a vehicle with high degree of accuracy in a smart entry system for the vehicle and, at the same time, preventing a required time from a locking or an unlocking operation of a door from the outside of the vehicle to the reception of an ID signal and an ID reference from getting longer. SOLUTION: A transmitter controlling unit 22 of a transmitter 2 receives an automatic charging signal s and, at the same time, a split mode signal d is transmitted when the automatic charging signal s is received. Usually, while a smart keyless controlling unit 4 sets a transmitting mode in a normal mode, when a mobile receiving antenna 63 receives the split mode signal d, the transmitting mode is set in the split mode.
