[0144] Please refer to the accompanying drawings to further describe the present invention.
[0145] As shown in Figure 6, the present invention provides a hardware-in-the-loop simulation test bed for an integrated controller of an automobile chassis, which includes a host computer 1, a target computer 2, and an electronic control unit 3. The degree of freedom dynamics model, tire road surface model, hydraulic and braking system model, engine and transmission system model, and the establishment of a digital simulation model for evaluating and optimizing the control strategy of each driving condition, converted into C code format, via Ethernet The net is received by the target machine 2 and downloaded to its CPU. The electronic control unit 3 controls the normally open valve and the normally closed valve of the solenoid valve 5 and the DC motor, and receives the current status signal of the solenoid valve 5 through the PCL board 4 and through the PCL board The card 4 is fed back to...
