The invention discloses a vehicle state detection method and a vehicle state detection device. The vehicle state detection method comprises steps: strength of a magnetic field of a corresponding carport is detected; the change rate of the magnetic field strength within a preset time period is calculated; and according to the change rate of the magnetic field strength, the state of a vehicle on the corresponding carport within the time period can be judged. Through the above technical scheme of the invention, the technical problem that the vehicle state can not be delicately detected in the prior art can be solved, and the change rate of the magnetic field strength of the corresponding carport can reflect the operation state of the vehicle and the vehicle engine, such as vehicle entering the corresponding carport, vehicle leaving the corresponding carport, vehicle engine closing-to-starting on the corresponding carport, and vehicle engine starting-to-closing on the corresponding carport.
