Vehicle distance control method and system for motorcade and vehicle

Abstract

The invention provides a vehicle distance control method and system for a motorcade and a vehicle. The method comprises the following steps that a distance Li of adjacent vehicles in the motorcade ismonitored; if all of the vehicle distances Li in the motorcade are greater than the predetermined vehicle distance L, the vehicle speed standard deviation Dv and the vehicle speed change threshold value D2 of the adjacent vehicles are compared; if the Dv is greater than D2, it is further judged whether an abnormal vehicle with the vehicle speed of zero appears in the motorcade in the predeterminedtime t; if the abnormal vehicle occurs, the position information of the abnormal vehicle is prompted to motorcade members; and otherwise, the first target vehicle speed Ve is sent to the plurality ofvehicles in the motorcade, and the acceleration or deceleration is correspondingly prompted according to the current vehicle speed of the plurality of vehicles. According to the vehicle distance control method for the motorcade the vehicle speed of the whole motorcade can be dynamically adjusted according to the distance change between the adjacent vehicles in the motorcade, the vehicle distanceof the adjacent vehicles is ensured to be kept at the proper distance, the purpose of dynamically keeping the vehicle distance in the driving process is achieved, and the driving safety is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle distance control method, system and vehicle of a fleet. Background technique [0002] When traveling in a convoy, such as a self-driving trip, the distance between the vehicles is easy to open due to the different skills of multiple drivers in the convoy. The location information of each vehicle. [0003] But when there are vehicles left behind in the convoy, if the drivers in the convoy want to shorten the distance and avoid falling behind, the drivers need to stop on the roadside or slow down to wait for the vehicles left behind, so that the total travel time is wasted, and, in the process of driving In the process, it is necessary to observe the companion's vehicle in real time, which will also cause a certain amount of distraction to the driver and affect driving safety. Contents of the invention [0004] In view of this, the present invention aims to propos...
