Vehicle security control system
First Claim
1. A vehicle security control system communicates with a separated communication device to receive from the same a demand signal to prohibit or permit engine operation, said vehicle control device comprising:
- a key for operating the vehicle, said key providing an ID signal when it is used;
a display for displaying information on the engine operation;
a first communication unit for receiving the ID signal;
a second communication unit for receiving the demand signal sent from said separated communication device; and
control means for controlling the engine operation according to the demand signal,wherein said control means prohibits said display from displaying the information on the engine operation when permitting the engine operation if said separated communication device provides the demand signal to prohibit engine operation.

Abstract
A vehicle security control system receives from a separated communication device a demand signal to prohibit or permit engine operation via an immobilizer. The vehicle control device includes a display for displaying information on the engine operation, a communication unit for receiving the demand signal from the separated communication device and a remote security ECU for providing a control signal according to the demand signal, an immobilizer ECU for setting or unsetting the immobilizer according to the control signal. The immobilizer ECU prohibits the display from displaying the information on the engine operation when the immobilizer ECU unsets the immobilizer even when the separated communication device provides the demand signal to prohibit engine operation.
