Abstract

The invention discloses a combine test bed for an electric power steering (EPS) system. The combine test bed comprises a bed body, a power steering system installed above the bed body and a load simulator installed below the bed body, the power steering system comprises a steering wheel, a steering input shaft connected with the steering wheel and a steering output shaft connected with the steering input shaft, the steering input shaft is connected with a torque sensor, and the torque sensor detects the value of torque of the steering wheel, the load simulator comprises a gear and rack type direction machine connected with the steering output shaft, and the direction machine is driven by a brushless motor. According to the combine test bed, data transmission is conducted through a wireless communication module according to a Bluetooth wireless communication protocol, no transmission communication line is needed, and stability of EPS transmission signals is guaranteed; multiple vehicle types can be simulated on the same test bed; EPS is not limited by occasions, transmission signals are stable, and service life is long.

Description

technical field [0001] The invention relates to the technical field of vehicle chassis performance testing equipment, in particular to a comprehensive test bench for an electric power steering system. Background technique [0002] In recent years, with the popularization of automobiles, the demand for international energy consumption is increasing day by day, and there is an urgent desire at home and abroad to have new energy vehicles to replace the existing high energy consumption vehicles. It has been paid more and more attention by people, and its market share is also increasing day by day. The electric power steering system has to undergo long-term tests at the beginning of the research and development stage, and the most important part of the bench test is that only after the bench test can the subsequent real vehicle test be carried out. Electric Power Steering (EPS) technology is a new technology in the field of automobile steering in recent years, and has achieved r...
