Description

technical field

[0001] The invention relates to the field of performance testing of vehicle electric power steering systems, in particular to a performance testing platform for electric power steering systems of industrial transport vehicles. Background technique

[0002] Electric Power Steering (EPS for short) is a power steering system that directly relies on the motor to provide auxiliary torque. In recent years, it has become a research hotspot in the domestic vehicle field. at a relatively basic stage. The performance of EPS is directly related to the safety and reliability of the vehicle, driving comfort, sensitivity and lightness of operation.

[0003] The electric power steering system can be mechanically divided into mechanical steering system and power steering system. The main component of the mechanical steering system in most electric power steering systems is the torque signal acquisition structure, which cannot complete the power steering of different styles ...
