PURPOSE:To prevent passengers from being sensible of the variation of car- height by reducing the car-height adjusting speed when a traveling-stop detecting means outputs a traveling signal and increasing the adjusting speed when a stop signal is output. CONSTITUTION:The car-speed data of a car-speed sensor 50, car-height data of car-height sensors 40A-40C, signal of a manual switch 70, and the signals of door switches 91A and 91B are input into a control circuit 60, which calculates the car-height at present and judges the traveling or stop of a car according to a prescribed program. Then, the electric conduction to solenoids 23A-23C and 32A-32C is controlled so that the car-height adjusting speed is high when the car is in stop state and in the opened-door state, and said adjusting speed is normal in the closed-door state, and said adjusting speed is low in high-speed traveling state, and said adjusting speed is normal in the low-speed traveling state. Therefore, the variation of car-height is not sensed by passengers. |
