This paper studies the research status and development trend of the Internet of Vehicles and vehicle information acquisition system. According to the basic functional requirements and basic design principles of the vehicle information acquisition system, the overall design scheme of the system is proposed. The key technologies used in the system design are also studied Provide convenience for vehicle positioning and navigation services. In order to facilitate the intelligent dispatching of intelligent public transport vehicles, the information collection module designed by the system provides the collection of various information of vehicles, such as the number of people on board, the opening and closing of doors, fuel consumption and driving status. In this way, the control center can formulate corresponding more intelligent scheduling strategies, and manage vehicle operation more effectively and conveniently.
