Time window determination method and device, equipment and storage medium

Abstract

The invention discloses a time window determination method, apparatus and device, and a storage medium, and is applied to the field of intelligent transportation. The method comprises the following steps: obtaining task information and m vehicles in the vehicle-road cooperation system, wherein the task information comprises n tasks and n task processing time tn in one-to-one correspondence with the n tasks, each task is a task required to be completed by a single vehicle, each vehicle executes the single task at the same time, the task processing time is used for representing the time requiredfor processing the single task by the single vehicle, and n and m are positive integers; calculating average task processing time and single task maximum time according to the task information and the m vehicles; and determining an upper limit and a lower limit of a time window according to the average task processing time and the maximum time of a single task, wherein the time window is used forestimating the time required for completing n tasks by parallel processing of m vehicles. According to the method, the time window can be accurately determined, and the working efficiency of the vehicle-road cooperation system is improved.

Description

technical field [0001] The present application relates to the field of intelligent transportation, in particular to a method, device, equipment and storage medium for determining a time window. Background technique [0002] The vehicle-road coordination system includes a traffic management platform and multiple vehicles controlled by the traffic management platform. The traffic management platform can assign multiple tasks to multiple vehicles. The task may be a road condition sensing task, a signal light sensing task, a vehicle distance sensing task, a weather broadcast task, and the like. [0003] Among them, one vehicle can only process one task at the same time, and multiple vehicles can process multiple tasks at the same time; one task can only be processed by one vehicle and cannot be interrupted. Before assigning a batch of tasks, the traffic management platform needs to estimate the completion time of the tasks, that is, how long it will take multiple vehicles to pr...

Problems solved by technology

[0005] The embodiment of the present application provides a method, device, device, and storage medium for determining a time window, which can solve the problem of determining the time window in the related art. When the number of vehicles is small and a single vehicle needs to handle multiple tasks, the vehicle cannot Processing and completing this batch of tasks within the time window leads to inaccurate estimation of the time window and reduces the working efficiency of the vehicle-road coordination system
