The invention discloses a vehicle service system comprising a cloud server, a vehicle owner service client, a parking lot station service client, a vehicle-borne positioning unit, a vehicle incoming and outgoing detection unit, a parking card, a parking spot information bulletin board, and an indoor parking spot guidance unit. The cloud server is connected with a user, a parking lot station, the vehicle-borne positioning unit and the indoor parking spot guidance unit in a two-way mode, and connected with the vehicle-borne positioning unit in a one-way mode. The system can provide real-time idle parking spot query, parking spot reservation, vehicle guidance and other services for vehicle owners. The additionally-arranged indoor parking spot guidance unit of the system can provide accurate indoor guidance service for vehicles under the condition that the GPS and other satellite positioning signals are poor or the network communication signals are unstable, so as to provide more user-friendly intelligent vehicle services for vehicle owners, improve the travel efficiency of vehicle owners, and reduce energy consumption.
