The invention is a system for use in automobiles for preventing and frustrating carjacking attempts. The system includes a Radio Frequency Identification Tag (RFIT) kept by the user and an interrogating system on the car that periodically reads the RFIT in order to confirm that the driver does have permission of the owner to continue to drive the car. The system on the car includes a microprocessor driven transceiver controller printed circuit board. The circuit board is hard wired into a number of different control systems including the fuel delivery system, emergency lights and horn. In the event that the user has been forced out of the car, the RFIT will no longer be in proximity to the interrogating system and the proper code will no longer respond to the interrogating signal. The control system will then take steps to shut down the operation of the vehicle engine and send out audible and visual emergency signals.

A vehicle system includes a remote function controller, and a data bus adaptor cartridge removably coupled to a data bus adaptor cartridge connector for permitting communications between control circuitry and at least one vehicle device over the data communications bus. The control circuitry may couple to the data bus adaptor cartridge through serial or parallel interfaces. The control circuitry may generate digital command codes, and the data bus adaptor cartridge may convert the digital command codes into data communications bus signals according to a desired protocol. The control circuitry may also read digital codes, and the data bus adaptor cartridge may convert data communications bus signals into digital codes according to a desired protocol for the control circuitry.
摘要:
A method of safeguarding against manipulation of an odometer or trip recorder in a motor vehicle, in which the instantaneous odometer reading is determined when the engine of the motor vehicle is stopped and that odometer reading is stored in an on-board control unit, in particular an engine control unit. Moreover, the instantaneous odometer reading of the odometer on restarting the engine is determined, and the odometer reading found on restarting the engine is compared with the stored odometer reading. Suitable measures are initiated for the case when the odometer reading found on restarting the engine and the stored odometer reading do not match.

The invention relates to a mechanism for electronically disabling a motor vehicle. More specifically, the invention relates to a transmitter that is aimed by law enforcement personnel at a receiver attached to a motor vehicle driven by a suspect. The transmitter emits signals that cause the receiver to trigger a relay to open thereby terminating the power to the ignition coil (or to a microprocessor) and shutting off the engine of the suspect's motor vehicle.

A security system to prevent unauthorized starting of the engine of a vehicle has a remote control unit (18) equipped with a transponder which, on reception of an interrogation signal using at least one reception aerial (20), transmits an identification code group using a transmitter unit (40). Located in the vehicle is a control unit (12), which on actuation of a starter button (26) within the vehicle, transmits the interrogation signal, and subsequently checks the identification code group transmitted by the remote control unit. Starting of the engine will only be possible when the identification code group coincides with the code group expected by it. Connected to the reception aerial (20) is a signal detector (28), which has a reaction threshold level that can be toggled between a high value and a low value. This signal detector will relay the interrogation signal to further processing stages only when the interrogation signal level exceeds the set reaction threshold.

A keyless entry system for a vehicle comprises a portable remote unit and a vehicle-mounted base unit supporting two-way communications. The remote unit includes a first transceiver and a control and is operative to transmit a command signal to the base unit in response to actuation of the control by a user. The base unit comprises a second transceiver and a control circuit, which controls a function in a vehicle. The base unit outputs control signals to control a vehicle function in response to receipt of commands from the remote unit. The base unit also transmits an acknowledgement signal to the remote unit responsive to the command signal.

An anti-theft vehicle system for a vehicle wheel having a rotational axis including a signal generator to generate a first predetermined signal around a first predetermined perimeter and to generate a second predetermined signal around a second predetermined perimeter at least partially disposed within the first predetermined perimeter, at least one inhibitor disposed within the vehicle wheel to selectively engage and disengage the vehicle wheel to resist and allow rotational movement of the vehicle wheel about the rotational axis, a rotatable structure disposed within the vehicle wheel and cooperating with the at least one inhibitor for moving the at least one inhibitor between an engaged position and a disengaged position with respect to the vehicle wheel, and a receiver disposed within the vehicle wheel to receive a first predetermined signal and second predetermined signal to activate the rotatable structure to move the at least one inhibitor between the engaged position and the disengaged position.
摘要:
A vehicle security system includes a transmitter to be carried by a user, a controller at the vehicle responsive to the transmitter, and an information display unit connected to the controller. The information display unit may include a first housing for positioning adjacent a front windshield area of the vehicle, and an indicator, such as an alphanumeric indicator, carried by the first housing and being driven by the controller. The controller is preferably switchable among a number of modes, and cooperates with the information display unit for indicating a current mode to the user. The information display unit may further include a control switch carried by the first housing. The control switch may be connected to the controller for switching the controller to a desired mode.
