Title: Control system for on-vehicle electronic equipment
Inventor: SOMA SATOSHI
IPC: B60R11/02
Filed: 1987-10-02
Abstract: PURPOSE:To inhibit the operation of an electronic equipment when it is stolen by inhibiting normal operation until a code number of an inserted card coincides with a code number stored on a control unit side under a state that the control unit is connected to a battery mounted on a vehicle. CONSTITUTION:When a programmable card 7 is inserted into a card inserting port 1a of the control unit 1, switches 9,8 are turned on and the set code number is stored in a memory 3. The code number is inputted by an operation part 5 in the control unit 1, and when the code number coincides with the number stored in the memory 3, a microcomputer 2 starts normal operation as a remote changer for a compact disk. If both the numbers are different from each other, a lock state is maintained and the control unit 1 is disconnected from the battery 4 mounted on the vehicle without starting normal operation. Thus, the normal operation can be inhibited until input operation is retired.
