Abstract

The invention discloses a vehicle speed assessment method and device. The vehicle speed assessment method comprises the following steps of acquiring the vehicle stroke data containing a vehicle speed;according to the vehicle stroke data, searching speed map data corresponding to a vehicle stroke track from a generated speed map; and according to the comparison result of the acquired vehicle stroke data and the searched speed map data, assessing a vehicle speed. In the provided scheme, a vehicle speed condition can be accurately reflected.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a vehicle speed evaluation method and device. Background technique [0002] With the development of the Internet of Things, the analysis and application of the big data of the Internet of Vehicles is becoming more and more important for the driving of vehicles. The general vehicle speed assessment is based on the absolute speed of the vehicle and the speed limit of the road, which is not detailed enough and not easy to monitor. The traffic speed on the road is often strongly related to time, and the difference between the road speed limit and the actual traffic speed is variable. In addition, vehicle speed is not only related to the road, but also has a great relationship with the speed of other vehicles on the road. [0003] Therefore, the existing related art uses the absolute speed to evaluate the vehicle speed, which has relatively large defects. Contents of ...
