Abstract: A vehicle includes a first motor, a second motor, a battery, a decider, a first calculator, a second calculator and a controller. The decider detects a state of the battery and determines whether the detected state is a state where charging the battery is restricted. The first calculator calculates, when the first motor generates the regenerative electric power under the state where charging the battery is restricted, a target energy consumption representing a target value of electric power that the second motor is to consume to drive the engine by using the regenerative electric power. The second calculator calculates an actual energy consumption that the second motor requests to maintain rotating speed of the engine. The controller adjusts angular acceleration of the engine and the second motor, using a difference between the target energy consumption and the actual energy consumption.
