Motor vehicle is a widely used transportation facility. The car ownership of residents in China is rapidly increasing with the continuous development of economy. The increasing number of motor vehicles results in more traffic accidents while providing convenience for social production and the people's life. According to the statistics, among all road traffic accidents in China, rear-end collision accidents of motor vehicles account for more than 70%. Therefore, it is of great significance for improving road traffic safety by analyzing causes of rear-end collision, and taking active measures to reduce the occurrence of rear-end collision accidents. A rear-end collision is a traffic accident in which the head end of a following vehicle crashes into the rear of a preceding vehicle when the two vehicles run in the same lane at a following distance. When the preceding vehicle decelerates or changes the lane, and the driver of the following vehicle does not brake in time or give up overtaking, a rear-end collision accident occurs easily. It is very important for the driver to focus on the taillight of the preceding vehicle, and timely judge the driving state of the preceding vehicle to prevent rear-end collision. In the prior art, no driving assistance device is available to help the driver judge the driving state of the preceding vehicle. If the driver of the following vehicle is temporarily distracted for some factors (e.g., telephone ring, conversation of passengers or some special events in sight) and ignores prompt information of the taillight of the preceding vehicle, a rear-end collision accident occurs easily.
