Method for determining the speed of a wheel on a motor vehicle

Abstract

Abstract The invention relates to a method for determining the speed of a wheel on a motor vehicle. To achieve this, an acceleration sensor is mounted on the wheel. According to the invention, the frequency omega or the cycle T of an alternating signal caused by the influence of the ground acceleration g is determined as the speed of the wheel. Said alternating signal is contained in the acceleration signal provided by the acceleration sensor. The method can be used in automatic tyre-pressure monitoring systems to assign signals transmitted by a wheel electronic system by radio to a specific wheel position on the motor vehicle and to control the transmission rate of a wheel electronic system according to the speed.
