Abstract: A vehicle 1 towing a trailer 4 is fitted with three video cameras 5, 6, 7 fitted to the rear of the vehicle and on each door mirror. A view from any camera can be presented to the driver on a display 11. A predicted trailer path, calculated in a computing unit 10, is also presented to the driver on the display 11 as guide lines overlaid on the camera view. The computing unit 10 is also configured to calculate a hitch angle by tracking the position of a trailer-mounted marker in the camera view.

Abstract: A security system is disclosed which is suitable for use in a passive entry and passive starting arrangement for a vehicle 10. A set of transmitters in the form of coils A, B, C are spaced around the vehicle 10, one A, B in each door mirror 20R, 20L and one in a high level brake light 16 at the rear end. Operation of a door handle initiates an access challenge from the vehicle 10 which is sent out successively on a plurality of the coils A, B, C. A portable transponder 26 carried by an authorised user is adapted to pick up the challenge signal and send back to a security controller 18 a response signal in which is included vector information relating to the relative positioning between the vehicle 10 and the transponder 26.

Abstract: A tire pressure monitoring system (12) for a vehicle (10) includes a speed sensor (38) generating a speed signal indicative of vehicle speed, a timer (44) generating a time signal, a warning status memory (26) having warning statuses therein. The system further includes a plurality of rolling tires in respective rolling location. The plurality of rolling tires (14a), (14b), (14c) and (14d) have respective rolling transmitters (16a), (16b), (16c) and (16d). An auxiliary tire (14f) in an auxiliary location has an auxiliary transmitter (16f) that generates an auxiliary sensor transmission signal. A controller (22) is coupled to the rolling transmitters, the spare tire transmitter and the warning status memory (26). The controller (22) receives the auxiliary sensor transmission signal.

Abstract: A security system which is suitable for use in a vehicle. The security system is a passive entry and passive re-mobilization system in which a security controller transmits a command signal LCs to a remote transponder, which replies with a LF response signal LRs. If an LF response signal is not received in response to the transmission of a command signal LCs, the security controller re-transmits the command signal, again as an LF command signal LCs. On determining that a command signal is a re-transmitted command signal, the remote transponder re-transmits the response signal as an UHF response signal URs.

Abstract: A security system suitable for a vehicle 10 comprises a remote transponder 16 and a transmitter/receiver 14 which is mounted on the vehicle 10 and which is associated with a controller 12 for controlling the security functions of the vehicle 10 in response to a signal from the transmitter/receiver 14. The transponder 16 includes a transmitting means 18 which is arranged to transmit a security signal in one or more of a predetermined range of channels. The transmitter/receiver 14 is arranged to scan the range of channels and to determine in which one or more of those channels the security signal has been transmitted.

Abstract: A vehicle security system comprises a transmitter 18 for transmitting coded signals, a receiver 16 for receiving the coded signals, and a control unit 14 for operating an engine immobilization system 12 in response to receipt by the receiver 16 of a valid coded signal. The transmitter 18 is arranged to transmit the coded signal as a sequence of pulses of electromagnetic radiation which are amplitude modulated at a modulating frequency, and the receiver includes an audio frequency filter arranged to pass signals having a frequency within a range including said modulating frequency. This allows the filtering out of high powered interfering signals which are of the same radio frequency as used in the system, but which are not modulated at the same audio frequency.

Abstract: A security system for detecting the fracture of a pane of glass of a motor vehicle comprising a fracture detector mechanisms in the form of a resilient sealing member. The resilient sealing member, which is normally in physical contact with the glass, has at least one sensor integrally formed therein by molding the at least one sensor into the resilient sealing member. The electrical state of the at least one each sensor, which is monitored by a control mechanism, is changed when the glass is fractured and, upon fracture, an appropriate warning device is energized by the control mechanism in response thereto. An anti-trap device may also be included in the resilient sealing member in order to detect the presence of foreign objects.
