Abstract
An all-wheel-drive electric vehicle includes one or more front electric motors, one or more rear electric motors, an accelerator sensor, a vehicle speed sensor, and a control unit. The one or more front electric motors are configured to directly drive front wheels. The one or more rear electric motors are configured to directly drive rear wheels. The accelerator sensor is configured to determine an operation amount of an accelerator. The vehicle speed sensor is configured to determine vehicle speed. The control unit is configured to control drive of the one or more front and rear electric motors based on the operation amount of the accelerator and the vehicle speed. The control unit is configured to change an allocation of driving force between the one or more front electric motors and the one or more rear electric motors with a bias toward the rear wheels in a case where the operation amount of the accelerator is increased at or above a predetermined rate in a state in which the vehicle speed is higher than or equal to a predetermined speed.
