PROBLEM TO BE SOLVED: To provide an electric-vehicular control apparatus capable of suppressing occurrence of a failure in engaging an engagement element due to an insufficient lowering of motor torque when increasing a power generation volume associated with a down speed change.SOLUTION: A control apparatus is used for an electric vehicle that includes: a travelling-motor MG driven with power from a fuel cell 30 and a strong-electric battery 40; an automatic transmission 10 for switching between engagement and disengagement of a meshing clutch and a friction clutch during a speed-change; and a control unit 100 for controlling the fuel cell 30, travelling-motor MG and automatic transmission 10. During a shift-down speed change, the control unit 100 increases a power generation volume of the fuel cell 30; calculates absorption-possible spare power Wgen_batt on the basis of a state of the strong-electric battery 40; calculates motor lower-limit torque on the basis of the absorption-possible spare power Wgen_batt and power generation volume; and increases disengagement-side clutch transmission torque to the motor lower-limit torque or higher. |
