制御装置。 The electric motor 12 that drives the drive wheel 10 and the battery 13 are connected via a chopper 23, and the chopper 23 is controlled by a controller 24 having a function of controlling the chopper 23 with different acceleration characteristics depending on the operating stroke of the accelerator 9. At the same time, a means for detecting the turning operation of the steering wheel 11 is provided, and based on this detection signal, the controller 24 controls the chopper 23 with poor acceleration characteristics, and when there is no detection signal, the controller 24 A vehicle speed control device for a battery lift truck, characterized in that a chopper 23 is controlled by good acceleration characteristics.
