Automobile chassis integrated controller hardware in-the-loop simulation test stand

Disclosed is a car chassis integrated controller hardware in-the-loop simulation test bed; a car multi-condition digital simulation mathematical model is established on a host machine, translated into C code format, received by a target machine through the Ethernet and then downloaded into the CPU of the target machine; an electronic control unit controls eight electromagnetic valves and receives the state of the electromagnetic valves through a PCL card to control the various car condition digital simulation model running and feedback information stored in the target machine. The car chassis integrated controller hardware in-the-loop simulation test bed has the advantages that the test bed realizes the hardware-in-the-loop of an ECU and an actuator so as to achieve more accurate prediction results of various control parameters; in the early stage of the research and development of the chassis electronic control system, the test bed optimizes the control parameters of extreme dangerous condition; the test bed also simplifies the test environment, and all the performances and optimized parameters obtained in the test are closer to that of real car testing.
