The present invention relates to a brake pipe length estimation device (12) and a method to detect the length of a brake pipe (10) in a vehicle (especially a vehicle containing multiple cars), which reflects the length of the vehicle and can be used to calculate the number of cars connected together, and thus detect the completeness of the vehicle. The brake pipe length estimation device (12) is configured to generate an additional air flow into the brake pipe to cause pressure waves, to detect the occurrence of resonances, and to measure the resonance frequencies. The method is provided to determine the brake pipe length based on the measured resonance frequencies.
