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 unit at the front is the leading unit; each unit is composed of at least one vehicle equipped with the vehicle-mounted system described below, 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...

Abstract

The invention discloses a separation and recombination method for line driving. A motorcade is formed by at least two units, and the frontmost unit is a leader unit; each unit is composed of at least one vehicle, the unit with only one vehicle is called a single vehicle unit, if more than one vehicle exists in the unit, the unit is called a multi-vehicle unit, the vehicle at the forefront of the multi-vehicle unit is a unit leader vehicle, the unit leader vehicle of the leader unit is called a queue leader vehicle, all the unit leader vehicles are dispatched in a unified mode through the queue leader vehicle, and the vehicles in the unit are dispatched in a unified mode through the corresponding unit leader vehicle. The separation and recombination method for line driving comprises the following strategies: a secure tracking strategy; a safe lane change strategy; a queue build / join strategy; and a queue separation policy and a maximum spacing limit policy. The separation and recombination method for line driving can flexibly achieve separation and recombination of the line driving.

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...
