Abstract

In a vehicle remote-control system, an anti-theft unit includes a vehicle control module, which can receive a disarm signal directly from a signal transmitting key, and which can change from an armed state, in which an inactive state of an ignition system is maintained, to a disarmed state, in which the ignition system is activated, upon receipt of the disarm signal. A starting unit includes a starting device, which generates an enable signal upon receipt of a starting control signal from a remote controller, and which controls starting operation of the ignition system when the vehicle control module is at the disarmed state and the starting device receives the starting control signal. A signal connector is enabled by the enable signal so as to relay the disarm signal from the key to the vehicle control module.

Claims

1. A vehicle remote-control system for controlling an ignition system of a vehicle, comprising:

an anti-theft unit including

a signal transmitting key capable of wirelessly transmitting a disarm signal, and

a vehicle control module adapted to be coupled to the ignition system, and capable of wirelessly receiving the disarm signal directly from said key when said key is within a first transmission distance from said vehicle control module,

said vehicle control module being capable of changing from an armed state, wherein said vehicle control module is adapted to maintain an inactive state of the ignition system, to a disarmed state, wherein said vehicle control module is adapted to activate the ignition system, upon receipt of the disarm signal;

a starting unit including

a remote controller operable so as to wirelessly transmit a starting control signal, and

a starting device adapted to be coupled to the ignition system and capable of receiving the starting control signal from said remote controller, said starting device generating an enable signal upon receipt of the starting control signal, and being adapted to control starting operation of the ignition system when said vehicle control module is at the disarmed state and said starting device receives the starting control signal; and

a disarming device including a signal connector connected electrically to said starting device so as to receive the enable signal therefrom,

said signal connector being enabled by the enable signal so as to be capable of wirelessly receiving the disarm signal from said key and so as to be capable of wirelessly transmitting the disarm signal received thereby to said vehicle control module when said key is within a second transmission distance larger than the first transmission distance from said signal connector,

said signal connector being inhibited from relaying the disarm signal from said key to said vehicle control module when said signal connector fails to receive the enable signal from said starting device.
