Method for evaluating of RPM of motor vehicle's entails comparing measured RPM with computed RPM, and generating condition signal in event of deviation between measured and computed RPM beyond threshold

摘要

The method for the evaluating of a RPM of a motor vehicle's wheel entails determining the wheel RPM by a measurement technique, computing the RPM of the wheel from a vehicle model which estimates the speed of the vehicle from the driving power and if necessary additional vehicle and environment parameters, and from this speed the RPM of one of the wheels. The measured RPM is then compared with the computed RPM, and a condition signal is generated in the event of a deviation between the measured and computed RPM beyond a specified threshold. An independent claim is included for a system for the evaluating of a RPM of a motor vehicle's wheel.
