Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0024] In the description of the present invention, unless otherwise specified, " / " means "or", for example, A / B may mean A or B. The "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone These three situations. In addition, "at least one" and "plurality" mean two or more. Words such as "first" and "second" do not limit the number and order of execution, and words such as "first" and "second" do not necessarily limit the difference.

[0025] The embodiment of the present invention provides a control method. When the control device near the intersection determines that there is a queue in the detection area b...

Abstract

The invention discloses a control method and device, relates to the field of intelligent transportation, and is used for solving the problem of low utilization rate of road resources. The method comprises the steps: acquiring the driving speed and the first distance of vehicles in a first queue at the current moment and the minimum duration of the first queue; determining a target speed of the vehicle in the first queue according to the driving speed of the vehicle in the first queue at the current moment, the first distance and the minimum duration of the first queue; determining the target duration of the first queue according to the target speed of the vehicles in the first queue; and under the condition that the target duration of the first queue is smaller than or equal to the green light remaining duration, sending a first control message to the vehicles in the first queue, wherein the first control message is used for indicating the vehicles in the first queue to drive accordingto the target speed of the vehicles in the first queue. The embodiment of the invention is applied to the Internet of Vehicles system.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a control method and device. Background technique [0002] In the networked environment of intelligent traffic vehicles, in order to make better use of road resources and simplify vehicle control and management at intersections, vehicles can be organized into queues (a queue includes multiple vehicles) for control and management. [0003] Specifically, the first vehicle in a queue is used as the head vehicle, and the head vehicle can communicate with the roadside unit at the intersection and other vehicles in the same queue. After receiving the control message sent by the roadside unit, the lead vehicle sends an instruction message to the other vehicles, so that the other vehicles maintain the same running state as the lead vehicle. [0004] Due to the different travel speeds and queue lengths of vehicles in different queues. In this way, during the green light time, w...
