電気車制御装置
Document Type and Number:
Japanese Patent JP6539538
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To restrict occurrence of vehicle movement in a reverse direction relative to a desired advancing method.SOLUTION: An electric vehicle control device 100 includes: a current detector 12 for detecting electric current i flowing in an electromotor 1; a speed calculator 13 for computing rotational speed ωmc of the electromotor 1 on the basis of the detected electric current i and a voltage command V*; a slip frequency command generator 14 for generating a slip frequency command ωsr of the electromotor 1; an adder 15 for generating a frequency command ωi obtained by adding the computed rotational speed ωmc to the slip frequency command ωsr; a frequency restrictor 110 for generating a restricted frequency command ωiL restricting a rotational frequency of the electromotor 1 according to a rotary direction of the electromotor 1, from the frequency command ωi; and a torque controller 16 for generating the voltage command V* on the basis of the detected electric current i, the restricted frequency command ωiL and a torque command Tqr.SELECTED DRAWING: Figure 1
