<P>PROBLEM TO BE SOLVED: To suppress generation of a step between a torque variation and an input rotation number, the step being caused during a period between the end of a speed change and the start of the next speed change, and to complete continuous speed change by high-quality speed change, while improving the stepped sense in the continuous speed change and shortening the time required for speed change. <P>SOLUTION: A control apparatus for an electric vehicle includes a motor/generator MG, a stepped automatic transmission AT, and right and left rear wheels RL, RR in a drive system, and controls the rotation number of the motor/generator MG so that a transmission input rotation number becomes a target input rotation number, during a speed change of the stepped automatic transmission AT. An FR hybrid vehicle includes a speed change time motor control means (Fig.7) for maintaining torque control of the motor/generator MG from a current speed change step to a step, immediately preceding the last speed change step, when the speed change between adjacent speed change steps from the current speed change step to the last speed change step is determined as being a continuous speed change that is performed continuously over a multiple number of times (YES in Step S3), and for changing the motor/generator MG from torque control to rotation number control, when the speed change is started from the step immediately preceding the last speed change step to the last speed change step. <P>COPYRIGHT: (C)2011,JPO&INPIT |
