The invention discloses an intelligent grouping vehicle system, comprising a guiding vehicle module and following vehicle modules, wherein the number n of the following vehicle modules is determined by the actual traffic demand, wherein n can be 0; the guiding vehicle module of a vehicle queue can at least realize full-automatic driving of L4 level; the following vehicle modules of the vehicle queue can achieve the basic functions of automatic grouping and separation, automatic following and automatic parking; the modules of the vehicle queue realize information interaction and sharing throughwireless communication; and the modules of the vehicle queue can be remotely controlled by a dispatching center, and automatic grouping, automatic separation and automatic parking in a station are performed. The intelligent grouping vehicle system disclosed by the invention comprises one guiding vehicle module and a plurality of following vehicle modules. There is no physical connection among themodules, flexible grouping is achieved, the distance between vehicles can be reduced, the windage is reduced, the energy consumption is reduced, and the transportation efficiency is improved.
