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.

Abstract: A safety switch is coupled to a control line of a vehicle starting system, and includes a first electrical connector that terminates a second branch of the control line, a first resistor that connects a first branch of the control line to a first voltage source, a switch element having a first end connected to a second voltage source, and a second end terminated by a second electrical connector that mates with the first electrical connector, and a second resistor connected in parallel with the switch element. The switch element makes or breaks electrical connection between the first and second ends according to a detected position state of an engine hood of the vehicle. The starting system is enabled so as to permit remote-controlled activation of the vehicle only when a voltage drop, the magnitude of which is between the voltage outputs of the first and second voltage sources, is present at the control line.
