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

Embodiment Construction

[0082] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0083] Such as figure 1 As shown, a vehicle collision detection method based on a vehicle-mounted intelligent terminal includes the following steps:

[0084] Step 1: The vehicle-mounted intelligent terminal collects time-series data in real time through the sensors installed on the vehicle. The time-series data is the vehicle body parameter value during driving; the vehicle body parameter value includes the real-time current value flowing through the vehicle drive ...

Abstract

The invention discloses a vehicle collision detection method and system based on a vehicle-mounted intelligent terminal; it includes the following steps: the vehicle-mounted intelligent terminal collects time-series data in real time through a sensor installed on the vehicle; intercepts the time interval from the collected time-series data; Whether the vehicle has been parked in the time interval; if it has been parked, determine the parking time in the time interval; re-intercept the first parking time and the multiple adjacent to the first parking time from the time series data. A new time interval of the data at a moment, and judge whether collision detection needs to be performed in the new time interval; if detection is required, analyze the change of the vehicle body parameter value in the new time interval. Through the improvement of the collision detection algorithm, the invention can effectively improve the accuracy of the collision detection and reduce the false alarm rate.

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...
