Abstract

The simulation test bed comprises: car steering wheel, car steering column, electrically-driven power assisted steering unit, magnetic powder loader, corner sensor, servo motor, driving speed signal generator controlled by the electronic pedal, micro processor and computer. The input force moment of the steering wheel is manually provided by the test staff; the signal for simulating the road surface frictional resistance and the signal for simulating the road condition resistance are provided by the micro processor via the magnetic power loader and servo motor.

Description

technical field [0001] The invention relates to a simulation test bench for an electric power steering gear of an automobile. Background technique [0002] In the automotive industry, since the 1980s, the development of various automotive electronic control systems has become an important part of the development of automotive products. In the development process of automotive electronic control systems, simulation technology can provide a test close to reality for the performance test and verification of the control system in the early stage of product development, especially when there are no prototypes at the disposal. The environment becomes an important tool in the product development process. Among them, Hardware-In-Loop simulation, referred to as HIL simulation, has been widely used. [0003] In the HIL simulation system, the developed control devices (such as power steering control, engine control, brake anti-lock brake control, shift control, etc.) Components) are...
