Embodiment Construction

[0039] The present invention will be further described below in conjunction with accompanying drawing.

[0040] In this embodiment, a platoon driving separation and reorganization method, the fleet is composed of at least two units, each unit is composed of vehicles with the same or similar destinations, and the entire fleet is composed of the same or similar paths in stages, or the same or similar vehicles with full paths Similar to the composition of several small convoys, the destination of the vehicles in the general unit is more concentrated than that of the entire queue. The frontmost unit is the lead unit; each unit is composed of at least one vehicle equipped with the following on-board systems, a unit with only one vehicle is called a single-vehicle unit, and a unit with more than one vehicle is called a multi-vehicle unit , the frontmost vehicle in a multi-vehicle unit is the unit head vehicle, and the unit head vehicle of the leading unit is called the queue leader ...

Abstract

The invention discloses a separation and reorganization method for driving in platoon. The fleet consists of at least two units, and the frontmost unit is the leading unit; each unit is composed of at least one vehicle, and a unit with only one vehicle is called a single vehicle unit. If there is more than one vehicle in the unit, it is called a multi-vehicle unit. The frontmost vehicle in a multi-vehicle unit is the unit head vehicle, and the unit head vehicle of the leading unit is called the queue leader vehicle. All unit head vehicles are uniformly dispatched by the queue leader vehicle , the vehicles inside the unit are uniformly dispatched by the corresponding unit head vehicle; the platoon driving separation and reorganization method includes the following strategies: safe tracking strategy; safe lane changing strategy; platoon formation / joining strategy; platoon separation strategy and maximum distance limit strategy. The invention can flexibly realize the separation and reorganization of platooning.

Description

technical field [0001] The invention belongs to the technical field of automatic control and vehicle traffic, and in particular relates to a separation and reorganization method for platooning. Background technique [0002] The combination of automatic driving and unified traffic dispatch can realize the optimization of traffic efficiency and energy consumption. As a combination of semi-autonomous driving and local traffic unified dispatch, platoon driving can improve traffic efficiency and reduce energy consumption. It is one of the hotspots in the fields of automobile and transportation. one. The existing platooning method controls the entire fleet as a whole, and lacks flexible separation and reorganization scheduling, which may lead to a longer fleet and affect public transportation, or it may be difficult to reorganize the fleet after being interrupted by other vehicles, which reduces traffic instead. Efficiency and impact on user experience. [0003] Therefore, it is...
