[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 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.

Embodiment Construction
[0029] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0030] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0031] figure 1 It is a flow chart of a vehicle distance control method for a fleet according to an embodiment of the present invention.
[0032] Before describing the vehicle distance control method of the fleet according to the embodiment of the present invention, the fleet is first described, as Figure 4 As shown, the fleet contains multiple vehicles, such as n vehicles, and the speed of each vehicle is V n , the distance between vehicles is L (n-1) . The data interaction between vehicles in the fleet can be through 4G, 5G, DSRC and other communication methods. Wherein, the dotted arrow indicates the direction of the transmitted wireless signal. The solid lines represent the di...

The invention provides a vehicle distance control method, system and vehicle of a fleet. Wherein, the method includes: monitoring the distance L of adjacent vehicles in the fleet i ; if all vehicles in the convoy are at distance L i are greater than the predetermined distance L, then compare the speed standard deviation D of adjacent vehicles v and the speed change threshold D 2 ; if D v greater than D 2 , then further judge whether there is an abnormal vehicle with zero speed in the fleet within the predetermined time t; if there is an abnormal vehicle, prompt the team members with the location information of the abnormal vehicle; otherwise, send the first target speed V to multiple vehicles in the fleet e , and prompt acceleration or deceleration according to the current speed of multiple vehicles. The vehicle distance control method for a fleet of the present invention can dynamically adjust the vehicle speed of the entire fleet according to changes in the distance between adjacent vehicles in the fleet, so as to ensure that the distance between adjacent vehicles is kept at an appropriate distance, so as to achieve dynamic maintenance during driving. The purpose of vehicle distance is to improve driving safety.
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...
