The invention discloses an Internet of Vehicles synchronous control system and method based on virtual coupling, and the system comprises synchronous control units which are respectively disposed at a vehicle head and a vehicle tail, and each synchronous control unit comprises an electronic communication unit, a central control unit, and a virtual coupling control unit. The virtual coupling control unit comprises a vehicle tracking distance monitoring module, a relative braking tracking model operation module and a safety protection module; the vehicle tracking distance monitoring module is used for acquiring the speed of the virtual coupling vehicle and the distance information between the front and rear vehicles in real time; the relative braking tracking model operation module is used for calculating the speed difference and the relative braking distance of the master control vehicle and the slave control vehicle in real time; and the safety protection module is used for controlling the running states of the vehicle under different running working conditions in real time according to the speed difference and the relative braking distance of the master control vehicle and the slave control vehicle, so that the virtual coupling slave control vehicle can be braked and stopped without collision under the condition that emergency braking is applied to the master control vehicle under the most unfavorable condition.
