The invention discloses a pure electric vehicle semi-physical simulation test bench and a test method thereof, which belongs to the technical field of pure electric vehicle test. According to one technical scheme, the pure electric vehicle semi-physical simulation test bench comprises a physical part and a virtual system, wherein the physical part comprises an overall controller, an accelerator pedal, a brake pedal, a shift control panel, a switch box, a load box, and an AMT transmission mechanism; and the virtual system is a software model formed by CANoe hardware and CANoe software. The pure electric vehicle semi-physical simulation test bench and the test method thereof have the beneficial effects that a pure electric vehicle parameter can be set to test functions and performance of the overall controller, different pure electric vehicle models can also be set to test the overall controller, parts are few, the operation is easy, and the cost is low.
Description
technical field [0001] The invention relates to the technical field of pure electric vehicle testing, in particular to a semi-physical simulation test bench for pure electric vehicles and a testing method thereof. Background technique [0002] At present, domestic testing of pure electric vehicle controllers is generally based on the HIL (a model-based pure electric vehicle test platform) test platform or vehicle platform, which causes the following problems: [0003] (1) The HIL test platform is developed based on the model, with single performance, high price and high cost; [0004] (2) The test and development cycle of the vehicle platform is long, and only one type of pure electric vehicle can be tested, so the flexibility is poor; [0005] (3) The cost of vehicle platform testing is too high and has certain risks. Contents of the invention [0006] In order to solve the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide...
