Abstract

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.

Description

technical field [0001] The invention relates to a simulation test bench, in particular to a hardware-in-the-loop simulation test bench for an integrated controller of an automobile chassis. Background technique [0002] Integrated Control System of Vehicle Chassis (Integrated Control System of Vehicle Chassis) is currently the most typical and most advanced chassis control system, which combines anti-lock brake control (ABS), traction control (TCS) and direct yaw moment control (DYC) functions are integrated. The composition of the system includes sensors (wheel speed sensor, steering wheel angle sensor, integrated sensor) that reflect the driver's intention and vehicle driving state, actuators (solenoid valve, DC motor, electronic throttle), and electronic control unit ECU (Eletronic Control Unit) . The hardware-in-the-loop simulation test bench includes the vehicle model (body model, tire model, engine model and brake system model, etc.), electronic control unit ECU, and...
