Abstract

The invention belongs to the technical field of automobile electric power steering, and specifically relates to a performance test system for an automobile electric power steering system. The performance test system includes a testing stand pedestal, a motion control mechanism for providing experiment simulation kinetic energy input, and a measurement and control system for performing detection and acquisition of experimental data, wherein the measurement and control system includes a real-time controller, a sensor unit and a data acquisition module; the sensor unit is connected with the real-time controller through the data acquisition module; and the real-time controller is connected with an upper computer. The performance test system for an automobile electric power steering system can complete a performance test for an electric power steering system indoors so as to save the real vehicle experiment to effectively reduce the cost, and is high in accuracy and reliability.

Description

technical field [0001] The invention belongs to the technical field of automobile power steering, and in particular relates to a performance testing system for an electric power steering system of an automobile. Background technique [0002] The electric power steering system is a function that can provide assistance and assist the driver to complete the steering when the car is turning. The power source of the electric power steering is the battery. When the driver turns the steering wheel, the control unit of the power steering controls the output force of the power steering motor according to signals such as vehicle speed, engine speed, and torque. The pinion connected to the power steering motor drives The steering rack moves to reduce the steering resistance, pushes the steering wheel to turn, and the wheel enters the steering state. [0003] The working stability and handling characteristics of electric power steering are related to driving safety and vehicle performa...
