Control method

- The test bench is independently set with front and rear axles for speed control (ASR) / torque control (ATR) / road load simulation (ALR)

- In the road load simulation, inertia simulation can be implemented, as well as a variety of driving resistance loading schemes

- Direct method, function method, table lookup method, direct method (correction), function method (correction), and table lookup method

 

Test condition

Meet the conditions required for the following tests

- Automotive oil, electricity and other energy consumption tests

- Adding, decelerating and other dynamic performance tests

- Automotive power consumption and efficiency test

- Special test for new energy vehicles

- Special tests such as climbing and taxiing

- Customized test conditions according to customer test requirements

 

Driving style

- Driver + driver assistance (dynamically displaying the target speed and actual speed and deviation interval on the timeline)
