Abstract: In an immobilizer controller, a key-side identifying information stored in a key is collated (compared) with an immobilizer-side identifying information stored in the immobilizer controller. In a shift controller, the key-side identifying information is collated with a shift-lock-side identifying information stored in the shift controller. If the identifying informations do not coincide with each other in at least one of the immobilizer controller and the shift controller, neither a fuel-injection-control permitting command nor a shift-lock-cancellation permitting command is output. An engine is maintained in its inoperative state, and a transmission is maintained in a state where rotation of a driving-torque transmitting shaft is prevented. If the identifying informations coincide with each other in the immobilizer controller, it is possible to reinforce security in comparison with the case where the fuel-injection-control permitting command and the shift-lock-cancellation permitting command are output.

Abstract: An electronic control unit is provided for automatically activating a parking brake in dependence of at least one specified operating parameter or operating mode of a motor vehicle, which can be started without a mechanical key.

Abstract: In a security ECU, a CPU instructs a request generation circuit to generate a request signal in the normal operation mode. Thereafter, the CPU shifts from the normal operation mode to the low-power consumption mode. The request generation circuit utilizes clock signals generated by a clock signal generation circuit and continues operation even after the CPU shifts to the low-power consumption mode. Thus, the time for which the CPU operates in the normal operation mode can be reduced, and the power consumption of the entire system is thereby reduced.

An arbitration means is provided to determine to which one of the wireless control and the smart control the receiver is assigned. If the receiver receives a wireless signal from the communication device, use of the receiver is assigned to the wireless control.

This check result is erased when a predetermined time elapses or when the electronic key is likely to be taken out from the vehicle. When another check condition is satisfied, the ECU refers to the memory and skips the key check operation if the previous check result is stored in the memory.

Abstract: The present invention provides an electronic key system for a vehicle which is a type of starting the engine with pressing a button switch and can be operated at familiar mechanical movements thus easing the user or driver of an unfamiliar conception as well as improved in the operability and the protection against theft. When a quick-start switch mounted on the steering wheel is pressed after the code identification is valid, a CPU switches on the start switch to energize a starter motor. The CPU judges from a change in the voltage of an alternator that the engine starts running. As the engine runs, an ignition switch is automatically turned to the II position with a valet key inserted. The engine can be stopped by the valet key turning to the 0 position. In the parking state, the valet key may be detached from or accommodated in the ignition switch.

Abstract: The anti-theft system is placed in the initialization state by activating a key in the ignition lock in a predescribed manner that is unusual relative to the day to day operation. A bidirectional dialog then takes place with the key via an immobilizer system. If the dialog is recognized as authorized, a start value is transmitted, on the one hand from the immobilizer to the key and on the other hand from the key to the receiver of the lock system. The start value is used in the key to generate a rolling code, and is used in the receiver to generate a reference code to be compared with it.

Abstract: A vehicle control system includes a radio transponder to be carried by a user, and a radio transponder reader at the vehicle for generating control signals to enable at least one vehicle function based upon receiving a desired radio signal from the radio transponder when positioned in proximity to the reader. A jammer radio transmitter at the vehicle selectively prevents the radio transponder reader from receiving the desired radio signal from the radio transponder based upon a controller, such as an alarm controller of a vehicle security system, especially an after-market security system. The controller preferably includes a receiver for receiving remotely generated signals to operate the jammer radio transmitter. The control system may also include a remote transmitter for generating control signals to be received by the receiver. For example, the remote transmitter may be a portable transmitter carried by the user, or may be a satellite, cellular or paging transmitter remote from the vehicle.

Abstract: A key fob for remotely actuating vehicle functions incorporates switches and a control which can determine whether an actuation is inadvertent or intended. In a disclosed embodiment, the switches each include field limited capacitive switches which can determine the amount of surface area of ionic material in proximity to the switch. This allows a placement of switches on both sides of the keyfob without raising the intended danger of inadvertent actuation. If a control determines the switch is proximity to ionic material over its entire surface area, the control can determine that the actuation is inadvertent as it is probably actuation by the palm of a user. However, if the actuation is above a predetermine minimum, yet below a predetermined maximum, the control can identify the actuation as intended.
