PURPOSE:To smoothly shift the change gear of an electric automobile adopting a manual change gear system by generating the torque corresponding to the pressing down amount of an accelerator pedal while a clutch is engaged or making the rotating speed of a motor equal to the rotating speed of the wheel- side clutch disk of the clutch when the clutch is disengaged. CONSTITUTION:A controller 10 inputs the speed V of a vehicle from a speedometer 3, the rotating speed of a motor 8 from the encoder 9 of the motor 8, signals K indicating the engaging and disengaging states of a clutch 4 from the clutch 4, gear position signals G from a change gear 5, and accelerator pedal pressing down amount signals A from an accelerator pedal 7. The controller 10 makes the motor 8 generate torques in accordance with the signals A while the clutch 4 is engaged. When the clutch 4 is disengaged, the controller 10 controls the rotating speed of the motor 8 so that the rotating speed can become equal to the rotating speed of a wheel-side clutch disc 4a. Therefore, the gear shifting operation can be performed smoothly. |
