Abstract
An electric vehicle includes an electric motor outputting regenerative torque to a drive shaft connected to an axle shaft, a hydraulic brake providing braking force for the vehicle, and an electronic control unit. The electronic control unit is configured to execute a regeneration coordination switch in which at least part of the regenerative torque from the electric motor is gradually switched to the braking force from the hydraulic brake. The electronic control unit is configured to execute a vibration suppression control that restrains vibration of the vehicle. The electronic control unit is configured to increase frequency of execution of the vibration suppression control when the regeneration coordination switch is performed, as compared to frequency of execution of the vibration suppression control when the regeneration coordination switch is not being performed.
