Abstract

The invention discloses a man-machine co-driving steering system hardware-in-loop simulation testing platform, which belongs to the field of intelligent vehicle steering system simulation tests and control technologies thereof. The man-machine co-driving steering system hardware-in-loop simulation testing platform comprises a PC, a man-machine co-driving steering ECU, a driving simulator, a pre-positioned torque / rotation angle sensor, a post-positioned torque / rotation angle sensor, a CAN card and a data acquisition device, wherein the PC is connected with the man-machine co-driving steering ECU and the driving simulator, the man-machine co-driving steering ECU is connected with the driving simulator by means of the CAN card, the CAN card is connected with the data acquisition device, and the pre-positioned torque / rotation angle sensor and the post-positioned torque / rotation angle sensor are connected with the man-machine co-driving steering ECU. Compared with the prior art, the man-machine co-driving steering system hardware-in-loop simulation testing platform has a man driving mode and a machine driving mode, thus controls an output rotation angle and torque of a steering motor, monitors a rotation angle and torque of a steering system in the machine driving mode, ensures the synchronicity of torque / rotation angle signals, effectively avoids dangerous situations which are prone to occur in real-vehicle tests, reduces a number of real-vehicle test times, and reduces and saves the development cost.

Description

technical field [0001] The invention belongs to the technical field of simulation testing and control of a steering system of an intelligent vehicle, and in particular relates to a hardware-in-the-loop simulation testing platform for a steering system of a man-machine co-driving steering system. Background technique [0002] Man-machine co-steering system (MMCS for short) is a new type of steering system with dual torque / rotation angle sensors, including two working modes of human driving and machine driving. Its main functions are to control the output angle and torque of the steering motor, monitor the angle and torque of the steering system in the driving mode, and ensure the synchronization of torque / angle signals. However, when the smart car is running in the automatic driving mode, since there is no human hand input on the steering wheel, the torque sensor in the electric power steering system has no signal output, so currently the smart car can only be controlled acco...
