A hybrid vehicle has a drive comprising an internal combustion engine, has an energy converter comprising an electric machine that can be operated for recuperation purposes, and has a control unit that is operatively connected to an operating element, to the drive and to the energy converter. The hybrid vehicle glides when the drive is not in the propulsion mode of operation and with an electric motor operated in a recuperation intensity stage in a first drive state. Based on the control unit having made the determination that the operating element was actuated, the determination is made in the control unit as to whether a condition is present, whereby the duration of the actuation of the operating element is determined and it is determined in a comparison that the duration is below the time threshold value. If the condition is present, a changeover is made from the first drive state to a second drive state in which the hybrid vehicle is then operated.

Method for operating a hybrid vehicle and hybrid vehicle

The present invention relates to a method for a vehicle () having an electric machine (). The electric machine () is coupled to at least one wheel () of the vehicle (). The vehicle () can optionally be operated in at least a first operating mode () and a second operating mode (). In the first operating mode (), the electric machine () applies a torque to the wheel (), and in the second operating mode () the electric machine () does not apply any torque to the wheel (). In the method, a request for switching over between the first and the second operating modes () is detected and the vehicle () is operated in a transition operating mode () if the request to switch over from the first operating mode () into the second operating mode () is detected. In the transmission operating mode (), a torque is applied to the at least one wheel () counter to a rolling direction of the vehicle () for at least a predetermined time.

Method for a vehicle having an electric machine

In a method and a device for controlling hybrid functions in a motor vehicle, including at least one control unit, hybrid functions of a motor vehicle are controlled by the control unit, the control unit switching off at least one hybrid function above a predetermined battery temperature.

Method and device for controlling hybrid functions in a motor vehicle

A hybrid vehicle includes a combustion engine, an electric motor, and a drive train that is optionally connectible to the electric motor or the combustion engine. An operating mode of the hybrid vehicle is determined automatically as a function of a setpoint torque and an operating state of the hybrid vehicle, the operating mode specifying whether the combustion engine, the electric motor, or the combustion engine and the electric motor is/are used as the drive mechanism of the hybrid vehicle. The operating mode is determined at least such that an efficiency of the drive train including the drive mechanism selected in accordance with the determined operating mode is at a maximum. Depending on the determined operating mode, the combustion engine and/or the electric motor is/are coupled automatically to the drive train for operating the hybrid vehicle.
