A method of locating a wheel-mounted electronic device, such as a tire pressure monitoring device. A wireless signal is transmitted from an interrogation device from each of a plurality of interrogation locations. The signals are received by the wheel-mounted device and received signal strength is measured for each interrogation location. The wheel-mounted device then transmits, in respect of each interrogation location, a wireless signal indicating the measured signal strength. These signals are received by the interrogation device which determines from them a location of the wheel-mounted device with respect to a wheel.

A vehicle having a controller, a main and a buffer memory, and a pressure sensor for each wheel. At certain time intervals after triggering, tire sensor modules transmit a sensor data record by radio, containing an individual identification code, a tire pressure and trigger information. For quick and easy assignment of wheel positions to tire sensor modules after a wheel change, after switching on the ignition or the electrical system, a detection function and subsequently and conditionally a check function are carried out. During the detection function, triggering of all modules in an order characterizing the wheel positions is expected. The controller receives the records of the triggered modules and stores them in the order received. The check function checks the records stored in the buffer memory for plausibility and, in the event of a positive result, the records are stored in the main memory instead of older records.

A system for setting multiple tire sensor identification codes includes a database and a handheld device. The database is for inputting and storing multiple vehicle owner information and multiple tire sensor identification codes associated with the vehicle owner information. The handheld device is for obtaining the multiple tire sensor identification codes from the database and transmitting the multiple tire sensor identification codes to multiple tire sensors so that each of the tire sensors stores one tire sensor identification code.

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.

A sensor array and method therein for locating tire sensors on a vehicle is provided. The sensor array is arranged to detect tire sensors on the vehicle as the tires of the vehicle traverses the sensor array, and to identify each of the detected tire sensors on the vehicle. Furthermore, a control unit and method therein for locating tire sensors on a vehicle, wherein the control unit is arranged to communicate with the sensor array and an ECU on-board the vehicle is provided. The control unit is arranged to receive, from the sensor array, a signal indicating that tire sensors on the vehicle has been detected and identified, determine the tire position on the vehicle associated with each detected and identified tire sensor based on the obtained signal, and transmit, to the ECU, information indicating the determined tire position on the vehicle for each detected and identified tire sensor.
