[0002] With the development of society, cars have become more and more popular. The vehicle tail door controller is generally mainly used for controlling the operation of the vehicle tail door. In order to ensure the reliability of the vehicle tail door controller in use, load test is often required before use. The load of the vehicle tail door controller in use mainly includes a driving motor and a latching lock. There are two methods for load testing of the vehicle tail door controller in the prior art: one is to connect the vehicle tail door controller with the actual load on the vehicle for testing. Although this testing method can truly simulate the load condition of the vehicle tail door controller, it needs to be connected with the actual load on the vehicle, and the testing is very inconvenient. The second method is to use electronic components to replace the actual load. Although this method is convenient for testing, there is a large difference between the actual load. SUMMARY
