Abstract

The present invention provides a car electromagnetic and radio frequency resistance test method based on the auxiliary steering system to set the radio frequency antipity test environment; the steering wheel installation auxiliary steering system for the vehicle to be tested, and set the torque curve of the auxiliary steering system according to the steering wheel target turning corner curve.; When the vehicle to be tested does not apply electromagnetic interference and applied interference, the steering wheel is applied to the torque of the steering wheel, and the final target turning corner curve of the steering wheel and the actual corner curve of the steering wheel;The difference between the rotation angle of each direction; determine whether the test requirements meet the test requirements according to the turning angle of the direction of the steering wheel.The auxiliary steering system described by the present invention applies the torque curve of the steering wheel, and collects the actual corner curve of the steering wheel and the final target turning corner curve of the steering wheel, and accurately understands the anti -interference performance of the steering wheel under electromagnetic interference.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic compatibility testing, and in particular relates to an electromagnetic compatibility radio frequency immunity testing method for automobiles based on an auxiliary steering system. Background technique [0002] With the continuous improvement of the degree of automobile intelligence and network connection, the problem of automobile driving safety has become increasingly prominent. In the process of driving on the road, the steering performance of the steering wheel is affected by various environmental factors, and the electromagnetic compatibility problem in the environment has become a very important part. Based on this, it is necessary to carry out electromagnetic compatibility and radio frequency anti-interference test in the process of automobile development. During the test, it is verified whether the steering system of the newly developed model meets the standard requirements by moni...
