Abstract
PURPOSE:To improve riding sensation, by a method wherein, in a control device for an induction motor type electric vehicle, after output of a constant speed running command, power running or regenerative brake torque is throttled, and after lapse of a given time, a speed is regulated to a command value. CONSTITUTION:When a main controller 6 is brought into a constant speed running position, a constant speed command line 19 outputs a pattern throttle command to an fs pattern generator 7 and an IM pattern generator 8, and after lapse of a given time, the output of an inverter 2 is decreased. Change-over switches 9 and 10 are changed over by means of an output from an on-delay timer 51, and the output from the on-delay timer 51 is inputted to a target speed setter 20. A signal fr equivalent to a current speed is latched, and a following speed command signal fp is provided. A comparing amplifier 21 outputs a slip frequency signal fSP2 and a radio command signal IMP2 by means of a deviation between the two signals fr and fp. This constitution enables improvement of riding sensation.
