Engine Monitoring of a Formula 1 Racing Car Based on Direct Torque Measurement

A torque sensor has been developed that is able to measure under the severe conditions present in a racecar engine. Based on a robust concept originally developed for automotive applications the sensor has been adapted to the specific requirements of a Formula 1 installation. In the vehicle it has been integrated directly in the power train on the gearbox input shaft. With access to the actual engine output a range of applications can be performed in terms of engine and drive train monitoring. An engine map can be acquired directly on the track and the performance of gearshifts can be measured and optimized. The torque signal can also be used for efficient traction control.
