Abstract: A passive function control system (10) for a motor vehicle and a method of operating the system (10) are provided. The system (10) includes a vehicle based transceiver (14) for transmitting a challenge signal having a random number and an identification code. At least a portion of the random number and at least a portion of the identification code of the challenge signal are encrypted. A portable transceiver (16) receives the challenge signal and decrypts the encrypted portions of the challenge signal. The portable transceiver (16) transmits a challenge response signal having the random number only in response to a comparison of the identification code to a reference identification code indicating a match. A first controller (18) of the vehicle based transceiver (14) responds to the challenge response signal when the challenge response signal is related to the random number.

Abstract: The invention provides a remotely controllable bicycle lock and alarm system and a remote control device enabled to facilitate communication between the a remote control device and the lock and alarm system. Also provided in the lock and alarm system is an audible alarm for notification of the bicycle operator.

Abstract: The remote start control system may include at least one vehicle device associated with starting an engine of the vehicle, a remote start transmitter, a receiver at the vehicle for receiving signals from the remote start transmitter, and a vehicle remote start controller connected to the data communications bus for communicating with the at least one vehicle device associated with starting the engine of the vehicle. The remote start controller is also connected to the receiver and may be responsive to signals from the remote start transmitter. The vehicle device associated with starting the engine of the vehicle may include at least one controller, such as the engine management controller or the transmission controller, for example. Alternately, or additionally, the at least one vehicle device associated with starting the engine of the vehicle may include at least one vehicle sensor.

Abstract: A combined vehicle remote access, tire monitoring and vehicle immobilization system and method including a tire monitor for monitoring a tire parameter, the monitor including a transmitter for transmitting a radio frequency tire data signal, a vehicle access transmitter for transmitting a radio frequency vehicle access signal, and a vehicle activation transponder for receiving an interrogation signal and transmitting a vehicle activation signal for use in vehicle immobilization. The system and method further include a control module having a receiver and a controller for receiving and processing the tire data, vehicle access, and vehicle activation signals, and generating a display signal to display the information represented by the tire data signal, a vehicle access control signal to perform the vehicle access function, and a vehicle immobilization control signal to immobilize the vehicle if the controller fails to authenticate the vehicle activation signal.

Abstract: A information communicating device includes a GSM device coupled to a communication interface unit, an input/output interface unit and an anti-theft device coupled to the GSM device, an LP coupled to the GSM device and the communication interface unit for communicating with selected customer service centers, a NAVI and a satellite positioning unit coupled to the LP and the GSM device, for sending information to the LP and the GSM device. The vehicle drivers may receive useful information from the customer service center and to act precisely according to the received information.

Abstract: When starting an engine using its remote engine starter function in a guard mode, an engine control ECU outputs an engine status signal at H level prior to driving a starter motor. An anti-theft control device, upon reception of the signal, stores the engine operating status in a mode storage device and lower the detection sensitivity of sensors. This allows no false alarm to be generated, if the anti-theft system is initialized by the decreased voltage of battery at the time of driving the starter motor. In addition, the detection sensitivity of the sensors is low until the engine stops running, so that the sensors do not have risks torroneously detect the vibration of vehicle as an intruder.

Abstract: Sensor data of respective controlled objects of a vehicle are collected by calling a vehicle remote-control system provided to the vehicle via a mobile phone, and then these data are displayed on an LCD display panel 11c of the mobile phone. In this state, the controlled object to be remotely controlled is selected by operating a cursor (30) and an ON/OFF setting button (31), and then its ON or OFF state is set. At this time, the remote-control command data are transmitted to the vehicle remote-control system from the mobile phone to set the corresponding controlled object. The condition is transmitted once again to the mobile phone as the sensor data, and is displayed on the LCD display panel (11c).

Abstract: A control apparatus, including a first control device, located at, and capable of controlling, a vehicle or premises, which generates and/or transmits a first signal for controlling the vehicle or premises. The first control device generates and/or transmits the first signal in response to a second signal which is generated by and/or transmitted from a second control device located remote from the vehicle or premises. The second control device generates and/or transmits the second signal in response to a third signal generated by and/or transmitted from a third control device located remote from the vehicle or premises and remote from the second control device. The first control device or the second control device processes an access code associated with the vehicle or premises in order to ensure that the third control signal in an authorized signal.

Abstract: A door control system for vehicles has a transmitter and a receiver for detecting an electronic key in a first predetermined area around a vehicle. A control unit controls unlocking of a vehicle door by determining whether the detected electronic key is an authorized one. The door control system also has an object sensor for detecting an object entering into a second predetermined area covering and wider than the first predetermined area. The control unit activates the transmitter and the receiver only after the object sensor detects the object in the second predetermined area, thereby reducing power consumption.

Abstract: A signaling arrangement for a vehicle, in particular motor vehicle, comprising a ring made of translucent or transparent material enclosing the body of an element controlling contact in the vehicle and further comprising element for illuminating the ring. The lighting elements illuminate the ring made of translucent or transparent material in accordance with a lighting mode or another depending on whether the vehicle locking circuit is activated or not.
