Abstract

An electric power supply control device for a vehicle comprises a lock actuator for driving actuators of the vehicle and an operation switch for outputting an operation instruction signal to the lock actuator. A circuit for vehicle running system for actuating an engine of the vehicle and a steering lock circuit for actuating the steering lock actuator in a locking direction are connected, exclusively with each other, to a power supply circuit. Wireless communication is conducted between a driver'"'"'s transceiver and the vehicle when the vehicle engine is stopped and the power supply circuit therefor remains on, to automatically disconnect the power supply circuit.

Claims

1. An electric power supply control device for a vehicle comprising:

a lock actuator for driving a steering lock device of a vehicle and an operation switch for outputting an operation instruction signal to actuate said lock actuator,

a vehicle running system circuit for actuating an engine of said vehicle and a steering lock circuit for actuating said lock actuator are connected to a power supply circuit so that said vehicle 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, and

a steering angle sensor that generates a signal indicative of a steering position of a steering device of said vehicle, the output of said sensor is connected to the steering lock circuit by way of a circuit for detecting a lock-enabling position and also connected to the running system circuit by way of a circuit for detecting a lock-disabling position.

2. An electric power control device for a vehicle to control the operation of a plurality of actuators disposed on said vehicle by means of the transmission and reception of predetermined signals between transmitting/receiving means disposed on said vehicle and transceiver means carried by the driver of said vehicle, wherein said device comprises:

(a) means for supplying power;

(b) a plurality of actuators including an engine ignition unit connected to said means for supplying power;

(c) said transmitting/receiving means transmitting a predetermined request signal and receiving a predetermined code;

(d) said transceiver receiving said predetermined request signal and transmitting said predetermined code to said transmitting/receiving means upon receipt of said predetermined request signal, wherein said transmitting/receiving means further comprises;

(i) means for storing a predetermined code;

(ii) means for comparing said stored code with said transmitted code;

(iii) means for supplying an output signal to said means for supplying power when said stored code matches said transmitted code; and

(e) means for detecting engine ignition connected to said engine ignition unit for supplying an output signal to said transmitting/receiving means upon detection that the engine is stopped while said means for supplying power is supplying power, whereupon said transmitting/receiving means transmits said predetermined request signal to said transceiver and turns off said means for supplying power if said transmitting/receiving means does not receive said transmitted code from said transceiver in response to said predetermined request signal within a predetermined time period.
