PROBLEM TO BE SOLVED: To eliminate adverse effect such as retreat and overdamping in a grade, by setting a target speed to zero from the start command of a rolling stock until a specified period passes, giving a speed command setting a target speed to a definite value after a specified period passes, and controlling a driv ing motor by a speed deviation signal on the basis of a speed command and a current speed. SOLUTION: This automatic start equipment consists of a speed command part 1 which gives a speed command setting a target speed 12 to zero after a rolling stock starts and brakes 4 are released until a specified period passes, a control part 2 controlling a driving motor 3 on the basis of the target speed 12 and a current speed 14, and a driving motor 3 rotating wheels 5. The control part 2 consits of a comparison circuit 2a forming speed deviation 13 on the basis of the target speed 12 and the present speed 14, a driving part 2b controlling the driving motor 2 on the basis of the speed deviation 13, and a speed detector 2c detecting the current speed 14 of the rolling stock from the number of rovolution of the driving motor 3. |
