Abstract

The invention relates to a real vehicle testing method and device for a driver state monitoring system. The testing method comprises the following steps: 1, determining three factors of real vehicle testing; 2, defining a test case by combining three factors of a real vehicle test; 3, determining a correct standard test result of each use case according to a technical specification of a driver monitoring system so as to obtain a test evaluation index; 4, executing each test case, testing the driver state monitoring system, and recording a test result; 5, analyzing the function performance of the driver monitoring system according to the test result obtained in the step 4 in combination with the standard test result obtained in the step 3. According to the driver state monitoring system testing method, the driver face action characteristics are acquired, the CAN bus signals in the vehicle are acquired, the specific testing working conditions of the method are combined, the testing data are acquired to judge the function performance of the driver state monitoring system, and the testing accuracy of the driver state monitoring system in the real vehicle environment can be improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a method and device for a real vehicle test of a driver state monitoring system. Background technique [0002] With the development of automotive intelligent network technology, more and more car manufacturers are equipped with intelligent network configuration in their products, and the driver status monitoring function, as an intelligent network function, is also gradually launched on the market. Before the vehicle goes on the market, it is necessary to complete the test and verification of the functional integrity, reliability and performance indicators of the driver status monitoring function. At present, most of the test verifications for the driver status monitoring system are carried out by means of simulated robots and light simulation. This kind of test is too idealistic, lacks the authenticity of the scene, and cannot directly give the functional perfor...
