Vehicle testing device with friction force simulation function and vehicle testing method

The invention discloses a vehicle testing device with a friction force simulation function and a vehicle testing method. The vehicle testing device comprises a friction force simulation device and a power measuring device, and the friction force simulation device comprises a first friction assembly, a second friction assembly in friction connection with the first friction assembly and a driving mechanism; the driving mechanism drives the portion, in friction connection with the first friction assembly, of the second friction assembly to move close to or away from the portion, in friction connection with the second friction assembly, of the first friction assembly. The power measuring device is coaxially connected with the second friction piece, and the power measuring device operably outputs a load. The vehicle testing device with the friction force simulation function can simulate the normal driving scene of the vehicle to be very real so that the testing accuracy of the tested vehicle can be greatly improve
