## 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.

## Claims

### Claim 1

An electric vehicle having an electric motor for traveling, comprising:
an accelerator pedal;
a paddle type shifter in which upshift operation, downshift operation, and mode switching operation are pre-registered; and
a motor controller for controlling the electric motor,
wherein the motor controller is configured to:
switch a control mode of the electric motor between an automatic mode and a manual mode in response to the mode switching operation to the paddle type shifter,
in the automatic mode, change an output of the electric motor in accordance with operation of the accelerator pedal, and
in the manual mode, change 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 to the paddle type shifter.

### Claim 2 (depends on 1)

The electric vehicle according to claim 1, wherein
the paddle type shifter includes a pair of left and right paddles, and is configured to output an upshift signal in response to operation of one paddle and output a downshift signal in response to operation of the other paddle, and
the motor controller is configured to receive, as the mode switching operation, an input of the upshift signal and the downshift signal having a predetermined input pattern.

### Claim 3 (depends on 1)

The electric vehicle according to claim 1, wherein
the paddle type shifter includes a pair of left and right paddles, and is configured to output an upshift signal in response to operation of one paddle and output a downshift signal in response to operation of the other paddle, and
the motor controller is configured to receive, in the automatic mode, an input of the upshift signal and an input of the downshift signal as operation for switching strength of a regenerative brake.
