An ECU of a vehicle executes a regeneration process to control an electric motor so as to generate regenerative torque during deceleration caused by an accelerator OFF. The ECU executes a torque gradual decrease process to decrease the regenerative torque in a wheel slip detection state more gradually at a time when a brake pedal is depressed after a start of the deceleration and ABS control is not activated than a time when the brake pedal is not depressed after the start of the deceleration. The ECU executes a hydraulic pressure increase process to increase the upstream hydraulic pressure such that, when the ABS control is activated while the brake pedal is depressed after the start of the deceleration, the upstream hydraulic pressure has a value necessary for generating a braking torque having a magnitude according to the regenerative torque generated at a start of the ABS control.
