This invention relates to a gear shift method for an electric automobile, which is used upon changing a gear ratio of a transmission in the electric automobile. First, in step 1, when a change-over signal is outputted from a shift controller, output control of a motor, which has been performed in accordance with a stroke of an accelerator pedal, is canceled, and the transmission is changed into a neutral position. In next step 2, an output amount of the motor is controlled in accordance with a target motor output amount corresponding to a target motor output amount corresponding to a target motor rotation speed, the target motor rotation speed being calculated based on a vehicle speed at a time of the changing operation and a gear ratio of a selected target gear position. Then, in step 3, the transmission is changed into the target gear position. In subsequent step 4, an output of the motor is allowed to gradually return to an output amount corresponding to a stroke of the accelerator pedal. These features make it possible to perform a prompt and smooth change-over of a gear ratio even when the accelerator pedal remains depressed.
A gear shift control method for an electric automobile, said automobile being provided with an accelerator pedal for commanding an output amount of a drive motor, a transmission arranged between said motor and drive wheels and having plural gear ratios, and gear shift control means for outputting a gear-position change-over signal in response to any one of a changing operation of a gear position of the transmission by shifting operation means and in accordance with a running condition of a vehicle, comprising
A method for controlling a gear shift of a transmission for an electric vehicle, the electric vehicle having a motor controlled based on a depression amount of an accelerator pedal, comprising:
