Research of driving torque monitoring for electric vehicle

With the rapid development of electric vehicle market and the increasingly complex application of automotive electronic and electrical technology in electric vehicles, the functional safety technology of electric vehicles has also been more applied. Aiming at the integrated pure electric vehicle, in order to avoid the unintended acceleration caused by the failure of driving control function as the functional safety goal, based on the EGAS three-level monitoring concept, the second level torque monitoring algorithm is researched, and the co-simulation is carried out based on CarSim and Simulink. And the algorithm is applied and tested in an electric vehicle. The results of vehicle test and simulation provides guidance for the safety development of new energy vehicle driving control function.
