Problems solved by technology

An important means of assessment is to carry out the electromagnetic immunity performance test. Due to the limitation of the test means, in the past, only the electromagnetic immunity test of the BCM was carried out, and the anti-interference performance test for the cooperation between the BCM and the remote control was not carried out, so this performance has not been assessed.

Embodiment Construction

[0026] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment of various embodiments of the present invention.

[0027] See attached Figure 1-2 : BCM and remote control cooperate to realize remote remote control opening / closing. The basic principle is: the owner operates the remote control opening and closing button, the remote control sends out a fixed frequency (usually 315MHz or 433MHz) electromagnetic wave, and the BCM built-in receiving antenna decodes the signal after receiving the signal. After decoding and matching, the actuator is driven to perform the opening / closing action.

[0028] At present, there is a kind of car jammer on the market. Its working principle is that the jammer interferes with the BCM receiving the remote control signal by transmitting the same frequency as the car remote control, so that the decoding does not match, so that it does not perform the opening / locking action, which br...

Abstract

The invention relates to an electromagnetic immunity performance testing system of a vehicle body controller and a testing method of the system. The system comprises an anechoic chamber, an auxiliary device and a power source, wherein the auxiliary device, the power source, a remote controller and a BCM (body control module) of the vehicle body controller to be tested are placed in the anechoic chamber; the power source is connected with the BCM of the vehicle body controller and supplies power to the BCM; and the auxiliary device has a pneumatic power source, and is used for controlling the remote controller.

Description

Technical field [0001] The invention relates to a test system for the electromagnetic immunity performance of a body controller and a test method thereof, in particular to a test method to effectively assess the electromagnetic immunity performance of the coordination function of a body control unit (hereinafter referred to as BCM) and a remote controller, which specifically includes Time relay, control solenoid valve and matching test fixture. Background technique [0002] Electromagnetic compatibility technology is a brand-new technology that has emerged with the development of electronic technology in recent years. It involves many majors such as physics, microwave technology, computer, and information analysis and processing. It is multidisciplinary and has a high degree of technical complexity. With the widespread application of electronic technology in automobiles, the problem of electromagnetic compatibility of automobiles has become increasingly prominent, and emissions a...
