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 a device, which relate to the field of intelligent transportation and are used to solve the problem of low utilization rate of road resources. Including: obtaining the driving speed of the vehicles in the first queue at the current moment, the first distance and the minimum hour length of the first queue; according to the vehicle speed in the first queue at the current moment, the first distance and the minimum hour length of the first queue, Determine the target speed of the vehicles in the first queue; determine the target duration of the first queue according to the target speed of the vehicles in the first queue; The vehicles in the group send a first control message, where the first control message is used to instruct the vehicles in the first queue to travel according to the target speed of the vehicles in the first queue. The embodiment of the present 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...
