Vehicle control system and method and vehicle

The invention discloses a vehicle control system and method and a vehicle, and belongs to the technical field of vehicles. The system comprises a central controller and a plurality of vehicle parts, wherein the vehicle parts belong to a plurality of different functional domains; at least two vehicle parts in a first function domain in the plurality of function domains are connected through a first network and are directly connected with the central controller; at least two vehicle parts in a second function domain in the plurality of function domains are connected through a second network and are directly connected with the central controller; at least one vehicle part in the first functional domain is connected with at least one vehicle part in the second functional domain through a third network; the central controller is used for sending control information to at least one vehicle part. Therefore, in-domain vehicle parts are interconnected firstly and then are directly connected with the central controller
