[0059] 4) Traffic Accident Analysis Example 2: Two-vehicle Collision Traffic Accident Analysis

[0060] image 3 The middle is a schematic diagram of a typical traffic accident scene. The case situation: the driver of car A thought that the speed of car B was too high and turned on the right turn signal, causing him to go straight and collide with car B. By analyzing the data collected by car B and unfolding it on the time axis, such as Figure 4 shown. The driver of car B stepped on the brake lightly at first, and when he found that a collision might occur, he braked urgently, but still collided with car A, and the output of the longitudinal acceleration sensor increased sharply. From the curve, it can be clearly seen that car B did not turn on the right turn signal before the collision, and the left and right turn lights are a warning after the collision. Therefore, it is basically judged that the reaction of the driver of car B is completely correct, combined with the act...

Abstract

The invention discloses a passenger car driving data recording device and a method for accident analysis by using the device. 13 types of sensors and switches such as a steering wheel rotary angle sensor, a retarder gear switch and an XYZ three-axis acceleration sensor are installed at the passenger car; exact time when an accident occurs is recorded by using a real-time clock, and various data collected is stored by a Flash memory. Simultaneously, the device carries out data transmission and communication by various interfaces including CAN bus, and an iButton interface is used for identifying the identity of a driver; the whole device finishes signal acquisition, processing and storage by an ECU processor and a peripheral modulate circuit. Matched software can completely show the operation actions of the driver and the working conditions of the passenger car in the driving process so as to carry out accident analysis for the passenger car having accidents and restore actual conditions in the process of accident, thereby providing original reference data as efficient auxiliary decision support of claim settlement for accident recording and discrimination, doubtful points analysis of accident and responsible party confirmation of accident.

Description

technical field [0001] The invention relates to a passenger car driving data recording device and an accident analysis method using the device. Specifically, the accident analysis function is realized by recording various data during the driving process of a passenger car, and belongs to the technical field of passenger car information collection, recording and analysis . Background technique [0002] With the continuous advancement of China's urbanization process, the continuous heating up of the tourism market and the rapid development of high-grade road networks, road traffic is becoming increasingly busy, and road traffic accidents are on the rise, especially heavy and extraordinarily large road traffic accidents in long-distance passenger transport Frequent occurrence has brought huge losses to the country and people's lives and property. In order to more effectively supervise the driving behavior of drivers, so that the traffic safety management system can be truly im...
