Vehicle collision detection method based on vehicle networking platform

Abstract

The invention discloses a vehicle collision detection method based on a vehicle networking platform. The vehicle collision detection method comprises the following steps that a platform terminal acquires a data packet collected by a vehicle-mounted equipment terminal, a first feature vector is constructed, and speed, acceleration, and angular speed sub-vectors are subjected to extraction and abnormality detection based on the data packet and the basic data, based on the abnormality detection result, a second feature vector is constructed, collision analysis is performed on the second feature vector to determine whether a collision occurs or not, and after occurrence of the collision is determined, a process of determining the severity degree of the collision is further included. The vehicle collision detection method is compatible with all vehicle models, and can realize low-cost, high-precision and high-efficiency collision detection for multiple collision scenarios. Compared with anexisting scheme, the vehicle collision detection method can simultaneously analyze more collision data and is higher in analysis speed, and the process of transmitting the data packet enables the datato be higher in integrity, bandwidth costs to be less and the amount of wireless data to be smaller.

Description

technical field [0001] The invention relates to the field of Internet of Vehicles, in particular to a vehicle collision detection method based on an Internet of Vehicles platform. Background technique [0002] In the context of the Internet of Things, people have also begun to install various on-board devices for their cars, and use these devices to obtain vehicle speed, acceleration, external temperature, geographical location, driving images and other information, and upload them to the big data platform , so that users can use the APP to pay attention to their car in real time. More and more in-vehicle equipment manufacturers are also committed to providing more services to users. Among them, the use of in-vehicle equipment to pay attention to vehicle safety, especially the technology of collision detection is slowly emerging in the industry. [0003] At present, the collision detection technologies based on vehicle equipment on the market are summarized into the followi...

Problems solved by technology

The disadvantage is that the device can only simply judge whether a collision has occurred by simply comparing the sensed data with the set threshold, making the detection accuracy extremely low
