Title: Tire pressure monitoring device

Abstract: A device for monitoring the tire pressure on the basis of the signals provided by the individual wheel speed sensors includes an electronic evaluating circuit which determines correction factors for the wheel speeds of the individual wheels. The values of the individual correction phases are determined and stored in a learning phase. The deviation of the correction factors from the learnt values is detected and analyzed in an identification phase, and possible loss of tire pressure is signaled. A switch is mounted on the wheel suspension of each vehicle wheel which resets the memories, upon rebound of the wheel until its end position, and re-starts the learning phase for the correction factors.
