Research on the mathematical model and measurement method of instantaneous output power of vehicle driving wheels

Aiming to solve the problem that the internal resistance of the dynamometer is regarded as a constant force by the traditional test method, which causes the measurement precision of the vehicle driving wheel instantaneous output power to be insufficient, a measurement system for the drum movement was constructed, a measurement method for the vehicle driving wheel instantaneous output power was put forward, and a mathematical model of the vehicle driving wheel instantaneous output power was established. Model analysis and experimental results showed that the actual output power of the driving wheel was reflected more accurately by the proposed method, and the accuracy of the measurement results was not affected by the vehicle speed. The output torque of the vehicle driving wheel calculated by the proposed model was closer to the road running resistance of the vehicle, which provided technical support for the accurate no-dismounting and rapid detection of the vehicle driving wheel output power and the accurate simulation of the vehicle road running resistance by the dynamometer.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
