The application discloses a detection device, system and method for a parking actuator of a pure electric vehicle, and relates to the technical field of electric vehicles. In this application, the parameters of the corresponding components in the parking actuator (such as the assembly angle of the parking shift shaft, the position of the ratchet relative to the pawl, and the torque of the parking return spring, etc.) The measured parking actuator is simulated and modeled, so as to realize the detection of the parking actuator through the simulation model of the parking actuator. It eliminates the trouble of installation and disassembly brought by the real vehicle test, and improves the detection efficiency. The simulation model can reduce the influence of other components in the real vehicle on the parking actuator during the real vehicle test, thereby improving the detection accuracy.
Description
technical field [0001] The present application relates to the technical field of electric vehicles, in particular to a detection device, system and method for a parking actuator of a pure electric vehicle. Background technique [0002] Pure electric vehicles are widely sought after by the industry due to their energy saving and environmental protection. Therefore, the industry has been pursuing pure electric vehicles with good performance. The parking actuator affects the parking performance of electric vehicles, so it is often necessary to test the parking actuator before it is actually put into production. [0003] In the traditional method, the parking actuator is manufactured first, and then installed on a real vehicle for testing. However, this kind of detection, on the one hand, the installation and disassembly of the actual vehicle is cumbersome, requiring a large number of long-term bench, vehicle debugging and test verification, which not only wastes manpower and ...
