Electric power supply control device for vehicle

Claim 1

An electric power supply control device for a vehicle comprising: a steering lock circuit for actuating a lock actuator for driving a steering lock device of a vehicle, a circuit for a vehicle running system for actuating an engine of said vehicle, a power supply circuit for supplying electric power to said steering lock circuit and said circuit for the vehicle running system, a locking operation switch for outputting an operation instruction signal for actuating said lock actuator in the direction of locking said steering lock device, a code transmitter means carried by a driver for transmitting a predetermined inherent code signal upon receiving a predetermined request signal, a transmitting/receiving circuit disposed on the vehicle for transmitting said predetermined request signal to said code transmitter means and for receiving said predetermined inherent code signal transmitted from said code transmission means, a code comparison circuit for comparing said received predetermined inherent code signal with a predetermined code previously stored in said code comparison circuit, a running operation switch means disposed on the vehicle for actuating said transmitting/receiving circuit and connecting said vehicle running system circuit with said power supply circuit when said received inherent code signal coincides with said stored predetermined code, and an off switch disposed on the vehicle to be operated for disconnecting said power supply circuit for vehicle running from a power source and turning said power supply circuit to off, wherein said circuit for vehicle running system and said steering lock circuit are connected to a power supply circuit so that said running system circuit cannot be actuated when said steering lock circuit is enabled and said steering lock circuit cannot be actuated when said running system circuit is enabled.
