A remote control system for precisely identifying a distance from the vehicle to an entry key and favorably controlling a vehicle-mounted device such as a door corresponding to the distance. The system comprises a transmitter transmitting different types of response demand signals within a predetermined communication area outside the vehicle, a vehicle mounted receiver for receiving a response signal released from a portable transmitter/receiver in response to the reception of the response demand signal, a controller controlling the vehicle mounted device corresponding to the reception of the response signal by the vehicle mounted receiver. Locking and/or unlocking door(s) of the vehicle are controlled on the basis of whether or not the receiver receives the response signal to a response demand signal other than one having the largest communication area.

Remote control system for a vehicle

A remote door lock controlling apparatus for a vehicle performing a door lock control in response to a response signal received by a vehicle mounted receiver which is transmitted from a portable transmitter/receiver upon receiving a response demand signal from the vehicle is improved wherein the door lock control function is stopped by a request of the user or depending on the magnitude of a terminal voltage of a battery mounted in the vehicle.

Electronic key system for a vehicle

An anti-theft apparatus prevents a delay in engine start caused by an ID legitimacy determination performed by an immobilizer. When an ignition key is operated, a starter motor is immediately energized and an engine control unit and a theft detector are actuated at the same time. Then, when independent running of the engine is detected by a detector, an immobilization determining section determines whether an enable code has been provided from the theft detector. If no enable code is present, then the immobilization determining section issues a halt command to the engine control unit. Thus, as soon as the key is turned to the on-position, the engine is started, thereby preventing a delay in engine start caused by the ID determination performed by the immobilizer.

Anti-theft apparatus which permits the engine to start prior to ID

A vehicle anti-theft system in which, only when the ID signal is obtained from a right ignition key and when the vehicle anti-theft function is halted by the failure of an anti-theft circuit or theft detection unit itself, the start-up of the engine is permitted. The system comprises a unit for generating a start-up enable signal in response to a verification signal representing a right ID signal, and an engine control unit for performing the start-up control of the engine in response to the start-up enable signal and disabling the engine in response to a theft signal. The start-up enable signal generating unit generates a start-up enable signal in response to the fault signal. A dummy line for detecting a breakage is wired along various signal lines wired on the substrate of an immobilizer, which, if intentionally broken by an ill-intentioned third party, could cause a fault signal similar to that for the failure of the immobilizer to be outputted from a determination signal output terminal. If a break in the dummy line is detected, the engine control is inhibited even if the fault signal is detected.

Vehicle anti-theft system

A vehicle anti-theft system in which a registration of an ID code of a new key to a vehicle side cannot easily be made by an ill-intentioned third party. Provided are a first memory for storing ID codes of operation keys and a second memory for storing an ID code of an L-key. Of a particular ID code of an inserted key has been registered as an operation key in the first memory, an immobilizer code stored in an immobllizer code memory is sent out to an engine ECU to enable the engine to be started up, and if the registered L-key is inserted, and operation keys are successively inputted, the renewal mode for the ID code is activated to rewrite the ID codes of the previously registered operation keys with ID codes of subsequently inserted operation keys in the first memory.

Vehicle anti-theft device

A vehicle antitheft system comprising an ID code compare unit for comparing a key ID code obtained from an ignition key with a reference ID code stored in advance in the vehicle and generating an enable signal when these ID codes are in a preset relationship (for example, both codes are identical), an engine ECU for receiving the enable signal and enabling control of the engine when the enable signal is correct and a delay times that is started in response to generation of the enable signal and generates a signal which enables starting of the motor starter after the lapse of a preset time period following the generation of the enable signal (for example, at least period necessary for the engine ECU to store or identify the enable signal).
