Autonomous Sensor System for Monitoring Torque from the Flexplate – Year two

While torque is an important parameter in automotive performance, there are currently very few effective methods to monitor it in vehicles. The aim of this project is to develop a low-cost solution for real time engine torque monitoring. An autonomous sensor module will be developed and mounted to the flexplate connecting the engine and the transmission system in vehicles with wasted vibration energy in the flexplates being harnessed to power the sensor module. High-efficiency circuits and low-power, reliable torque sensing methods will be developed to achieve energy, processing and communication autonomy without batteries or wire connections. The developed system will be advantageous for its small size, light weight, long lifespan, and low cost. This project, taken on in collaboration with Magna Powertrain, will strongly underpin the development of intelligent vehicle technologies such as the driverless car system and powertrain control system in electric vehicles.
