Vehicle fall-behind prediction method and device based on time sequence and storage medium

Abstract

The invention discloses a vehicle fall-behind prediction method and device based on a time sequence and a storage medium. The method comprises the steps of determining the distance between a front vehicle and a rear vehicle before the driving of a motorcade, and forming an initial distance matrix; acquiring the real-time speed of the vehicles at a preset cycle time T after the motorcade departs; predicting the speed of the vehicles in the motorcade in the future preset time by utilizing a time sequence prediction algorithm based on an adaptive filtering method; and according to the distance between the front vehicle and the rear vehicle in the time sequence of the real-time speed of the vehicle, sending a fall-behind early warning when the distance between the front vehicle and the rear vehicle exceeds a preset threshold. The influence of system transmission errors on early warning management is reduced through data preprocessing, speed prediction is conducted through adaptive filtering time sequence prediction, the distance relation between the front vehicle and the rear vehicle is described, the relation between the front vehicle and the rear vehicle after overtaking and fallingbehind of the vehicle is updated, and early warning reminding is conducted on falling behind of the vehicle according to the new distance relation between the front vehicle and the rear vehicle.

Description

technical field [0001] The invention relates to the research on vehicle straggling in a fleet, in particular to a time series-based vehicle straggling prediction method, device and storage medium. Background technique [0002] In some application scenarios, vehicles often need to travel in groups and work together, such as self-driving travel fleets, etiquette fleets, and moving fleets. In such convoy activities, the convoy generally does not rely on navigation to navigate forward, but has a special guide on the first car to lead the convoy forward. If the convoy travels to an unfamiliar location, the vehicle may fall behind due to poor traffic conditions and other reasons, and the navigation equipment cannot provide effective trajectory navigation. Then the entire convoy needs to wait for the car behind to accelerate and follow, which is inconvenient and troublesome. [0003] At the same time, although the GPS position coordinates can be used to monitor the fleet's positio...

Problems solved by technology

[0005] The present invention aims to solve the problem in the prior art that it is impossible to predict whether a specific vehicle will fall behind when the fleet is moving. It proposes a time-series-based vehicle lagging prediction method, device and storage medium. real-time prediction of the distance and issue an early warning of falling behind
