Vehicle collision detection method and vehicle collision detection system based on vehicle-mounted intelligent terminal

Abstract

The invention discloses a vehicle collision detection method and vehicle collision detection system based on a vehicle-mounted intelligent terminal. The method comprises the following steps that the vehicle-mounted intelligent terminal collects time sequence data in real time through a sensor installed on a vehicle; a time interval is intercepted from the collected time sequence data; whether thevehicle stops in the time interval or not is judged; if yes, the parking moment in the time interval is determined; a new time interval of data comprising a first parking moment and a plurality of moments adjacent to the first parking moment before and after is re-intercepted from the time sequence data, and whether collision detection needs to be carried out in the new time interval is judged; and if detection is needed, the change condition of vehicle body parameter values in the new time interval is analyzed. According to the vehicle collision detection method and the vehicle collision detection system, by improving a collision detection algorithm, the accuracy rate of collision detection can be effectively improved, and the false alarm rate is reduced.

Description

technical field [0001] The invention belongs to the field of automobile safety, and in particular relates to a vehicle collision detection method and system based on a vehicle intelligent terminal. Background technique [0002] With the rapid development of society, the use of automobiles has greatly facilitated people's daily life. However, with the continuous increase in the number of automobiles, frequent traffic accidents have seriously threatened the safety of people's lives and property. Most of the emergency rescue of traffic accidents can only be found through manual methods such as calling the police or traffic police patrols. In some solutions, collision detection technology can be used to automatically send information to the traffic police department when a collision is detected to achieve similar alarms. function. [0003] The document with the publication number CN109357888A discloses a vehicle collision detection method, a vehicle and a computer-readable stor...

Problems solved by technology

[0004] However, in practice, it is found that the algorithm for judging whether a car has collided by acceleration is of poor practical significance, and it is easy to misjudge the driver's active emergency braking (sudden braking) as a collision accident
