Electric drive system test bench and control system

The invention relates to the technical field of electric drive system testing, in particular to an electric drive system test bench and a control system. And the control system realizes simulation of pavement excitation by controlling the test bench. A linear motor is installed at a suspension point position of a tested electric driving system, the linear motor supports the tested electric driving system and also serves as an excitation source to simulate excitation generated by a road surface in the running process of an automobile, and the output end of the electric driving system is connected with a first load motor and a second load motor. And the driving resistance of the automobile in the driving process is simulated. Besides, the test control system can control the work of the tested electric driving system and the linear motor according to the road spectrum information collected in the real vehicle driving process in combination with various sensor signals of the test bench, and simulates the road sur
