An electronic control unit sets a drivability target engine speed, sets upper limit engine power on the basis of the drivability target engine speed, and sets upper limit drive power by dividing the upper limit engine power by a rotational speed of a driveshaft. Then, the electronic control unit compares accelerator requested drive power with the upper limit drive power, sets target engine power such that lower one of the accelerator requested drive power and the upper limit drive power is output to the driveshaft, and controls an engine, a first motor, and a second motor such that the target engine power is output from the engine. In this way, a driver can receive further favorable drive feeling.

In a torque-based detection process, a control device detects an excess acceleration state of a vehicle when a duration time of a state in which a value obtained by subtracting a required torque from an actual torque of an internal combustion engine is equal to or greater than a torque threshold value is equal to or greater than a torque determination time. In an acceleration-based detection process, the control device detects the excess acceleration state of the vehicle when a duration time of a state in which a value obtained by subtracting a required acceleration from an actual acceleration of the vehicle is equal to or greater than an acceleration threshold value is equal to or greater than an acceleration determination time.

A method for operating a hybrid vehicle having an electrical energy store, an electric drive and an internal combustion engine, includes activating, by a driver of the hybrid vehicle, a battery control mode by actuating a defined operator control element. A special drive operating strategy for the internal combustion engine is triggered in the battery control mode with the electric drive switched off. An increased charging gradient is then obtained by the special drive operating strategy if a current state of charge of the electrical energy store is below one of a desired state of charge or a lower tolerance threshold with respect to the desired state of charge.
