Abstract
In a vehicle'"'"'s wheel position detecting apparatus, a first triggering device, attached to the vehicle'"'"'s body, outputs a triggering signal including information indicating that the triggering signal is for front wheels. A second trigging device, attached to the body, outputs a triggering signal including information indicating that the triggering signal is for rear wheels. The first and second triggering devices output the triggering signals simultaneously. A transceiver is attached to each of the front and rear four wheels. Each transceiver receives the triggering signal, calculates a reception intensity of the triggering signal, stores both the reception intensity data and the information into a frame, and transmits the frame. A receiver, attached to the body, receives the frame and processes the received frame to read out both the data and the information and use the read-out data and information to detect the positions of the wheels.
