Abstract
Provided is a vehicle control system that can prevent delays and losses in packet communication, prevent handover failures, and improve productivity while ensuring safety for various types of vehicles. The vehicle control system includes an on-board terminal mounted on a vehicle and including a plurality of wireless modems; a plurality of wireless base stations that wirelessly communicate with the on-board terminal, and form a plurality of cells; and a vehicle central control device that communicates with the on-board terminal via one of the wireless base stations. Each of the plurality of wireless modems is configured to be able to, when the vehicle moves across the plurality of cells, execute a handover to switch a connection to one of the plurality of wireless base stations to another. Each of the plurality of wireless modems is configured to be able to set threshold for executing the handover different from the others.
