Abstract: A method is for maintenance of a ground-level power supply for a transport vehicle. The device includes: a power supply rail, a detector of spatial coordinates of a vehicle; and a power supply shoe. The device and the shoe equip the same vehicle. The supply shoe includes a vibration sensor. The method includes measuring vibrations of the shoe and simultaneously detecting spatial coordinates of the vehicle during the movement of the vehicle along the rail, followed by comparing measured vibrations of the shoe with a threshold value, and determining spatial coordinates corresponding to vibrations above the threshold value.
