The invention discloses a vehicle model identifier with an alarm. The distance between a vehicle and the vehicle model identifier can be detected by using the vehicle model identifier. When the vehicle comes, a light curtain sensor and a double-piezoelectric film sensor in the vehicle model identifier are started, and the vehicle is identified. The vehicle model identifier comprises a cylindrical shell, the light curtain sensor, a distance sensor, a sound production device, a controller and the double-piezoelectric film sensor, wherein when the vehicle comes, the light curtain sensor and the double-piezoelectric film sensor in the vehicle model identifier are started, and the vehicle is identified, so that energy is saved; meanwhile, the distance sensor can detect the distance between the vehicle, a person or other objects and the vehicle model identifier, and an alarm is given.
