Background
Airbags are becoming increasingly interesting to users and important to automobile manufacturers as the primary passive safety system for automobiles. Mandatory national standard "automobile event data recording System" is implemented in the upcoming version. For simplicity, we refer to the automobile event data logging system (Event Data Recorder System) as an EDR system, and the corresponding functions and techniques we refer to EDR functions and techniques. The EDR regulation has clear requirements on the collision record times and record parameters of an EDR controller (RBG control box), and a whole vehicle factory and EDR part suppliers also actively develop functional tests and verification related to the EDR regulation so as to cope with the impact on the admission bulletin of the vehicle type after the release of the new regulation.
Currently, the method for integrally testing the EDR function of the whole vehicle mainly comprises the steps of shaking or knocking an EDR controller by a small hammer to enable the EDR controller to detect an event recording threshold or an airbag explosion threshold, and entering an EDR recording program to finish the recording of event data of the automobile. And then reading collision record information through a diagnostic tool or an EDR data extraction tool, comparing the collision record information with test conditions when the record is triggered, and judging the performance of the EDR controller and the integrity and accuracy of the record information. However, the above-mentioned shaking or small hammer knocking manner of the EDR controller has a plurality of disadvantages, shaking or knocking force cannot be controlled, the shaking direction cannot be controlled by knocking, the testing operation is difficult to standardize, the fault problem is difficult to reproduce, and the testing strength is greatly increased. So that the same operator operates the steps in the same way to obtain different test results, and even directly causes the EDR controller to record locking events (the air bag is exploded, the ECU is locked, and the test sample is scrapped), and the expected unlocking events (the recorded data can be covered, the ECU is not locked) are not obtained, and a new EDR controller sample must be reconfigured for continuing the test. Therefore, the method has great inconvenience for testing, the accuracy of the test result is not high, the test cost cannot be effectively controlled, and a new solution is urgently needed to be provided.
As in patent application No. 201822202679.9, the patent discloses an EDR acceleration simulation device of an automobile event data recording system, and the invention drives a workbench to move at a certain acceleration through a linear motor on a magnetic axis, so as to trigger the EDR to record an event. According to the method, the linear motor driving system is subjected to fine closed-loop control, so that acceleration values are quantitatively given, the trigger threshold value of the EDR controller can be finely judged, and the EDR controller is well subjected to performance test. However, for the integrated function test of the whole vehicle system, the device has the defects of high implementation and maintenance cost, difficult dynamic test along with the vehicle, incapability of quickly changing the test direction, complicated preparation process in the early stage of test and the like.
