The invention discloses a vehicle monitoring device, a vehicle management system, a vehicle-mounted device and a vehicle management method. The vehicle monitoring device, the vehicle management system, the vehicle-mounted device and the vehicle management method have the advantages that a parking space monitoring device sends first information to the vehicle-mounted device in a corresponding parking space through a low-frequency channel which is short in transmission distance and good in signal, so that the information of the parking space monitoring device can be sent to the vehicle-mounted device accurately, and vehicle management precision is improved; meanwhile, the parking space monitoring device acquires second information, which is sent by the vehicle-mounted device according to the first information, through a radio-frequency channel, so that returning the information by the vehicle-mounted device through the low-frequency channel is avoided, and energy consumption of the vehicle-mounted device is reduced; the vehicle-mounted device can upload vehicle identity information to a background management center through the parking space monitoring device and is bound with the corresponding parking space, so that precise vehicle parking space positioning is achieved.
