The invention provides a performance detection system and method for a drunk driving and fatigue driving discrimination system. The performance detection system comprises a modeling computer, a simulating machine, a driver operation data input device, a preprocessor, an ECU under test and a display device. The performance detection method comprises the steps of generating a C-language five-degree-of-freedom complete vehicle digital simulation model on the modeling computer; generating a simulating machine C-language five-degree-of-freedom complete vehicle digital simulation model on the modeling computer; downloading the simulating machine C-language five-degree-of-freedom complete vehicle digital simulation model to the simulating machine for real-time simulation calculation, and obtaining vehicle operating state data; inputting driver operation data and the vehicle operating state data into the preprocessor so as to respectively obtain noise-added driver operation data and noise-added vehicle operating state data; inputting the noise-added driver operation data and the noise-added vehicle operating state data into the ECU under test for driving state recognition; and performing comparative analysis on a recognition result of the ECU under test and an actual result to determine the detection performance of the ECU under test.
Description
technical field [0001] The invention relates to the technical field of active safety and testing, and specifically designs a performance detection system and method of a drunk driving and fatigue driving discrimination system. Background technique [0002] In recent years, the rapid increase in the number of motor vehicles and the number of drivers has caused the driving environment to deteriorate, and road traffic safety accidents have also increased year by year. According to the analysis of traffic safety accidents in recent years, drunk driving and fatigue driving have gradually become one of the main causes of traffic accidents. Traditional passive safety can reduce the driver's injury degree and ensure the safety of the driver when an accident occurs, but it cannot reduce the occurrence of traffic accidents. Therefore, from the perspective of active safety, people have designed a drunk driving and fatigue driving discrimination system. When the system recognizes that ...
