Embodiment 1

[0047] An embodiment of the present invention provides a test system for the electromagnetic immunity performance of the vehicle braking system. The test system for the electromagnetic immunity performance of the vehicle braking system includes: an electromagnetic interference system, which is used to apply electromagnetic Interference; Pneumatic auxiliary system 10, which controls the vehicle brake pedal 11 and / or accelerator pedal to make the vehicle reach a prescribed speed; Monitoring system, which includes a monitoring system for monitoring the brake light system Monitoring equipment outside the vehicle and monitoring equipment inside the vehicle for monitoring the brake failure alarm indication system.

[0048] The embodiment of the present invention provides a test system for the electromagnetic anti-interference performance of the vehicle brake system, which applies electromagnetic interference to the vehicle brake light system and the brake failure alarm indication sys...

Embodiment 2

[0063] as attached Figure 5 As shown, the embodiment of the present invention provides a method for testing the electromagnetic immunity performance of a vehicle braking system, the test method comprising the following steps:

[0064] Step 1: Apply a specified field strength to the vehicle through the electromagnetic interference system;

[0065] Step 2: At different frequency points, control the brake pedal 11 and / or the accelerator pedal of the vehicle through the pneumatic auxiliary system 10 to make the vehicle reach a specified speed;

[0066] Step 3: Monitor whether the vehicle brake light system and the brake failure alarm indicating system are normal through the monitoring system.

[0067] According to the above test results, the electromagnetic immunity performance of the vehicle braking system (brake light system and brake failure alarm indication system) is judged.

[0068] The embodiment of the present invention provides a test system and method for the electrom...

Embodiment 3

[0088] The embodiment of the present invention has carried out concrete test to the electromagnetic immunity performance of vehicle:

[0089] Before the test, it is necessary to confirm whether the brake light system of the vehicle and the brake failure alarm indication function are normal. The specific operation steps are as follows. Observe whether the brake light is on or off;

[0090] In the second step, the personnel in the car turn the ignition key to the "ON" position. After the self-inspection of the combined instrument is completed, observe the display of the brake failure warning light. If the warning light is not on, it means that the brake system is working normally. Step 1, if the warning light is on, it means that there is a fault in the brake system, and it needs to be overhauled until the fault is resolved, and if the warning light is not on, go to the third step;

[0091] In the third step, lightly step on the brake pedal 11;

[0092] Step 4: Personnel outsi...

Abstract

The invention discloses a test method for electromagnetic-interference-resistance performance of a vehicle braking system and belongs to the technical field of vehicle safety monitoring. The system includes an electromagnetic-interference system, a pneumatic-type auxiliary system and a monitoring system. In the method, electromagnetic interferences are applied to a vehicle braking lamp system and a braking-fault alarm indication system through use of the electromagnetic-interference system; the pneumatic-type auxiliary system is used to control a vehicle braking pedal and or / an accelerator pedal to a stipulated vehicle speed; and the monitoring system is used to monitor whether the braking lamp system and the braking-fault alarm indication system are normal so that the system is capable of testing the electromagnetic-interference-resistance performance of the vehicle braking lamp system and the braking-fault alarm indication system and thus potential safety hazards in driving are reduced. Use of the pneumatic-type auxiliary system does not affect an electromagnetic environment and is not affected by an outside electromagnetic environment so that test reliability and repeatability can be ensured effectively and test cost can also be reduced obviously. The test method for the electromagnetic-interference-resistance performance of the vehicle braking system is simple, easily controllable and comparatively high in economic applicability.

Description

technical field [0001] The invention relates to the technical field of vehicle safety monitoring, in particular to a system and method for testing the electromagnetic anti-interference performance of a vehicle braking system. Background technique [0002] The vehicle braking system includes mechanical mechanisms, hydraulic mechanisms, electrical mechanisms, etc. Among them, the electrical mechanisms, especially the brake light system and the brake failure alarm indication system contain sensor components that are susceptible to electromagnetic interference. When these components fail due to electromagnetic interference, , will give the driver or other road users false judgments and affect driving safety, so it is necessary to test its anti-magnetic interference performance. [0003] In the prior art, there is no specific test method for the electromagnetic immunity performance of the vehicle brake light system and the brake failure alarm indication system, which makes it dif...
