The invention discloses a vehicle remote control system based on 5G communication and high-precision positioning and a control device thereof. The control system comprises a laser radar, a high-definition camera, a high-precision positioning antenna, a sound control radar, a millimeter wave radar, a vehicle, a satellite, a time delay detection device, a 5G base station, the control device, a rack and a host. The control device comprises a chassis, a first gear, a second gear, a motor, a signal receiving module, a supporting rod, a first connecting rod, a second connecting rod, a third connecting rod and a first hydraulic cylinder. According to the invention, information of cloud, roads and vehicles is seamlessly connected by using digital and informatization resources, and remote vehicles, a management and control platform and a driving simulator are connected in real time by using development technologies of parallel vision and perception, parallel learning, parallel planning, parallel control and the like, so that the driving of the remote vehicles becomes measurable and controllable. The rapid response of a vehicle system to the environment is improved, the overall system cost is reduced, and vehicle-road interaction, multi-vehicle cooperation, parallel control and safe driving are achieved.
