Method and apparatus are disclosed for localizing vehicle TPMS sensors. An example vehicle includes a plurality of TPMS sensors, an antenna, and a processor. The processor is configured for determining signal strength values between each of the plurality of TPMS sensors and the antenna, and based on the signal strength values, determining a location of each of the plurality of TPMS sensors.

A wireless vehicle data communications device is adapted for mounting on a wheel hub assembly of a vehicle and incorporates a self-generating electrical power supply. The vehicle data communications device includes a housing, a microprocessor located inside the housing, a signal transmitting device, a signal receiving device, an electric generator, and an energy storage and supply medium. The housing is adapted to rotate simultaneously with the wheel hub assembly when the vehicle is in motion. The electric generator include a plurality of wire coils and magnets. One of the wire coils and magnets is attached to an independently influenced components carrier, and the other of the wire coils and magnets is designed to rotate substantially simultaneously with the housing. The wire coils and magnets are arranged such that rotation of the housing relative to the components carrier generates a magnetic field and induces an electric current.

A transmitter includes a transmitter control section, which generates transmission data to be transmitted to a receiver. The transmission data contains variable data and verification data. The verification data is data for causing a verifying section of the receiver to verify an ID code registered in the transmitter against an ID code registered in the receiver. The transmitter control section is capable of switching between a first state and a second state. The first state is a state in which fixed data representing identification information is transmitted as the verification data. The second state is a state in which computation data computed from the variable data and the fixed data is transmitted as the verification data.

Provided is an on-board device and a vehicle communication system that can expand the transmission range of signals that are transmitted from transmission antennas of the on-board device. An on-board device transmits signals to a portable device, from a plurality of first to fourth LF transmission antennas that are provided for a vehicle at positions that are separate from each other. The on-board device includes a transmission unit that transmits the signals from the first to fourth LF transmission antennas such that a transmission range in which the portable device can receive the signals is a range around the vehicle. The transmission unit substantially simultaneously transmits the signals from two or more transmission antennas among the first to fourth LF transmission antennas, to expand the transmission range.

A vehicle security system may include a vehicle controller and a first wireless communications device coupled thereto, and at least one wireless sensor. The wireless sensor may include a housing having a threaded mounting surface, a motion sensor carried by the housing, a second wireless communications device carried by the housing, and a sensor controller carried by the housing. The sensor controller is configured to determine when motion of the housing exceeds a first threshold, and send a first security alert message to the vehicle controller based thereon via the second and first wireless communications devices, and determine when the first threshold is exceeded for a predetermined time and enter a power saving mode based thereon. The at least one sensor may also include a power source carried by the housing to power the motion sensor, second wireless communications device, and sensor controller.

An apparatus for collecting and forwarding sensor signals for vehicles with sensors for monitoring wheel ends, with at least two inputs for sensor signals and at least one output interface for digital signals. The output interface can, for example, be a radio device and the apparatus can include a receiver for radio signals from tire pressure sensors. A method is for operating such an apparatus and includes transferring sensor signal dependent digital signals to the at least one output interface.

The present disclosure provides a vehicle control system. The vehicle control system includes a transceiver operating in a sub-GHz frequency band configured to transmit and receive data from a RKE user terminal of the vehicle, a set of TPMS sensors and at least one remote control terminal located outside the vehicle; and an ECU connected to the transceiver and configured to: perform lock or unlock and engine start functions in responding to data from the RKE user terminal, receive tire pressure data from the TPMS sensors and control the remote control terminal in responding to a user action.

A system and a method for a receiver in a motor vehicle to learn a position of a buckle switch is disclosed. The buckle switch indicates a buckled state or an unbuckled state of a buckle on a seat belt mounted to a removable seat. The method includes the steps of placing the receiver into a learning mode, indicating that the position of the buckle switch is to be learned, activating the buckle switch, and indicating that the learning is complete.

The present invention relates to a camera for a vehicle and a control method for the same and an exemplary embodiment of the present invention provides a camera for a vehicle which is provided in any one of a plurality of designated installation positions of the vehicle, including: an image sensor which generates a driving image; a receiving unit which receives a plurality of RF signals which are transmitted from a TPMS sensor unit which detects states of a plurality of tires included in the vehicle; and a position determining unit which determines which position among the plurality of installation positions is a position where the camera is installed, based on the plurality of RF signals which is received by the receiving unit.

A method for the hands-free access to a motor vehicle (V) is combined with a method for monitoring tire pressure. More particularly, wheel units (20, 21, 22, 23) belonging to the tire pressure recognition system detect the cessation of low frequency LF transmissions caused by the recognition of a badge B paired with the vehicle in order to trigger the measurement via the wheel units of the pressure and temperature values prevailing in each tire of the vehicle. These pressure and temperature measurements are sent to a central unit (14), which is mounted on the vehicle, so as to provide the driver with this information. The temperature and pressure measurements are transmitted to the central unit as soon as the measurements have been taken, irrespective of whether or not the driver has entered the vehicle.
