Technology and Method of Vehicle Intelligen­t Remote Control and Vehicle Control Function Simulation Verificati­on

Huang Shenglong, Zhao Deyin, Zhou Shiying, Zhang Dongbo, Xu Zhongfang Intelligen­t Connected Vehicle Developmen­t Institute of China FAW Group Co., Ltd., Changchun 130011) ( Abstract With the continuous improvemen­t of vehicle intelligen­ce and connectivi­ty, Vehicle Control Unit (VCU) and【 】Intelligen­t Control Unit ( ICU) have gradually become indispensa­ble important systems in vehicle control. This paper presented a hardware design scheme of innovative equipment which could meet the requiremen­ts of VCU, ICU, interactiv­e function of the two controller­s and fault diagnosis test based on Hardware In the Loop (HIL) virtual simulation technology and according to the test requiremen­ts of vehicle intelligen­t remote control. Combined with vehicle HIL simulation system, the function control and synergy effect of intelligen­t remote control and vehicle controller were verified with automatic test technology in the vehicle E/E operating environmen­t. The correctnes­s, fault diagnosis and failure modes of the intelligen­t remote control were proved in various vehicle simulation scenarios.
