ABSTRACT:
In a vehicle's wheel position detecting apparatus, plural transceivers respectively attached to the front and rear four wheels are provided. Each transceiver receives a triggering signal, calculates a reception intensity of the triggering signal, stores data indicating the reception intensity into a frame, and transmits the frame to a receiver attached to a vehicle's body. Each triggering signal radio-transmitted from the first and second triggering devices contains a startup command to starts up each transceiver and an execution command to allow each transceiver to calculate the reception intensity. The first and second triggering devices, which are responsible for radio-transmitting the triggering signal toward at least the front wheels and the rear wheels respectively, are positionally offset to either way in the body's lateral direction. A receiver receives the frames and uses the frames radio-transmitted from the transceivers to detect the wheels' positions using the reception intensity in each frame.
