Research on the application of advanced vehicle in loop simulation test approach for evaluating ACC

In this paper, a vehicle in the loop simulation test approach of performance evaluation for driving assistance system is proposed, which contains testing model validation method and testing execution procedure. The vehicle dynamics model of the vehicle on the dynamometer is proposed to control the road load simulation that applied by shaft-coupled dynamometer. The method of integrating radar simulator, camera simulator, dynamometer system, and real time machine and scenario software to the vehicle in the closed loop simulation test platform is proposed. The performance of the vehicle with ACC function is evaluated on the simulation test platform, as well as the tests on closed-road. The results demonstrate that the performance of the vehicle tested on the simulation test bench is highly consistent with the results of closed-road. The proposed vehicle in the loop test approach is useful for evaluating the performance in longitudinal scenarios.
