The Benchmarking of ESP Hardware-in-the-Loop Test Bench with Data from Real Vehicle

Abstract

The development of ESP Hardware-In-the-Loop(HIL) test bench has brought great benefit to the development of ESP system and could shorten the development period. Therefore the accuracy of ESP HIL bench is crucial to the development of ESP system. The adjustment of vehicle parameters is an important section in the simulation model and it decides the accuracy of the bench to a great extent. The vehicle parameters from actual measurements are limited, so it is very difficult to obtain a high-accuracy simulation model. The article offers a way to solve this problem. With CANoe from Vector Corp., the experiment data were gathered from actual vehicle and returned to simulation model through CAN telecommunication. This will enable the simulation model to operate in the same mode of actual vehicle. By contrasting the output of response, the vehicle parameters will be adjusted step by step, until the response of simulation model is same as the one of actual vehicle.
