The invention discloses a parking executing mechanism detecting device, system and method of a pure electric vehicle, and relates to the technical field of electric vehicles. Parameters (such as the assembly angle of a parking gear shifting shaft, the position, relative to a pawl, of a ratchet wheel, and the force moment of a parking return spring) of corresponding parts in a parking executing mechanism are collected through a sensor, thus a computer conducts simulation modeling on the really-tested parking executing mechanism conveniently, and the parking executing mechanism is detected through a simulation model of the parking executing mechanism. Troubles, brought by real vehicle testing, of mounting and demounting are omitted, and the detecting efficiency is improved; and through the simulation model, influences of other parts in the real vehicle on the parking executing mechanism during real vehicle testing can be reduced, and thus detecting accuracy is improved.
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 ...
