Abstract: Based on the principle of vehicle dynamics, this paper proposes a lightweight vehicle mass identification algorithm applied to embedded vehicle controller.According to the difference principle, the algorithm decouples the slope resistance, rolling resistance and acceleration resistance.Through the combination of simulation analysis and real vehicle test, the identification accuracy of the algorithm is verified, which results show that the estimated error can be controlled within 10%.
