  • Publication number: 20240359569
    Abstract: The electric vehicle of the present disclosure includes an accelerator pedal, a paddle type shifter, and a motor controller. The paddle type shifter is pre-registered with upshift operation, downshift operation, and mode switching operation. The motor controller switches a control mode of the electric motor between a manual mode and an automatic mode in response to the mode switching operation on the paddle type shifter. When the control mode is the automatic mode, the motor controller changes an output of the electric motor in accordance with the operation of the accelerator pedal. On the other hand, when the control mode is the manual mode, the motor controller changes an output characteristic of the electric motor with respect to the operation of the accelerator pedal in accordance with the upshift operation and the downshift operation of the paddle type shifter.
