Abstract


China's economy sustained steady and rapid development, the rapid increase in car ownership, followed by traffic accidents is also increasing rapidly. According to the data research shows that in many road accident if the accident occurred before a second potential effectively to alert the driver, 90% of the accidents can be avoided, as long as two seconds before the accident, the driver take appropriate measures, almost all accidents can be avoided. Automotive active safety systems can effectively reduce traffic accidents, at present, there are some automotive active safety systems in automotive applications and have achieved some results. However, the domestic automotive active safety systems such research-focused most dangerous condition is detected, while the warning trigger little research. This article is as a starting point, from the visual, auditory and tactile warning trigger other aspects of the research carried out accordingly. In order to find a more effective warning trigger. Through research and analysis, this paper established the first experimental realization of programs and procedures and identified based on auditory, tactile and visual warning is triggered based research strategy. In Driving Simulator software is implemented in the driving environment simulation, and in Windows XP and VC 6.0? Program platform environment, the development of control sounds, lights and vibration control opening and closing procedures, the auditory, visual, tactile, etc. different warnings triggered. Especially through self-control lights flicker frequency setting, and through auditory, visual and tactile warnings in different combinations to achieve the appropriate warning triggered. In this paper, the driver driving simulation environment for visual, auditory, tactile and three different combinations of warning experiment, analysis and comparison of a single or a combination of the driver warning trigger operation behavior. First through the driver's subjective judgment method selected program is suitable as a warning, and then with typical automotive active safety systems - lane departure warning system experimentally measured under different trigger warning the driver's response time. Finally, statistical analysis methods, depending on the warning triggered by the number of correct operation of the driver, the average response time and the variance of the three considered, analyzed more effective and suitable way driver warning. Subjective judgment by the driver experimental data obtained verify the driver's visual, auditory, tactile warnings ability to accept the universality of the data obtained from a typical experiment also reflects the driver's response to the warning trigger the general rule. In this paper, automotive active safety system warns the driver with a strong trigger the acceptability and effects which can be widely used in automotive active safety systems research and practical applications, but also for other human-computer interaction detection warning system way to provide a theoretical and technical support. ?
