Embodiment Construction

[0043] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0044] Any feature disclosed in this specification (including any appended claims, abstract), unless otherwise stated, may be replaced by alternative features that are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0045] Such as figure 1 As shown, this embodiment discloses a vehicle collision detection method based on the Internet of Vehicles platform, which is applied to a vehicle collision detection system. The vehicle collision detection system includes a vehicle-mounted device terminal and a platform terminal; including the following steps:

[0046] S1: A step in which the platform side acquires several data packets obtained by intensive sampling at the vehicle device sid...

Abstract

The invention discloses a car collision detection method based on the Internet of Vehicles platform, comprising the following steps: the platform side obtains the data package collected by the vehicle equipment side, and based on the data package and basic data, constructs the first feature vector, velocity, acceleration, angular velocity Vector extraction and anomaly detection. Based on the abnormality detection results, a second feature vector is constructed, and a collision analysis is performed on the second eigenvector to determine whether a collision occurs. After the collision is judged, the process of judging the severity of the collision is also included. The present invention is compatible with all car models, and can realize low-cost, high-precision, and high-efficiency collision detection for multiple collision scenarios. Compared with the existing scheme, the present invention can analyze more collision data at the same time, and the analysis speed is faster. The process of inventing transmitted data packets, resulting in higher data integrity, less bandwidth overhead and less over-the-air data volume.

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 information such as vehicle speed, acceleration, external temperature, geographical location, driving images, etc., 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 fol...
