Abstract: A battery electric vehicle includes a driving operation member including an accelerator pedal, a simulated gear shifting operation member, and a control device. The control device is configured to execute, by selection by a driver, a control mode in which a driver demand torque for driving an electric motor is calculated based on an operation amount of the accelerator pedal and operation of the simulated gear shifting operation member, and perform a hold assist when the control device detects that the battery electric vehicle is stopped on a road surface having a gradient. The hold assist includes outputting a hold assist torque that is a drive wheel torque in an opposite direction of gravity, and ending the output of the hold assist torque and performing switching to output of the driver demand torque, in response to exceedance of the driver demand torque over the hold assist torque.
