An electric vehicle axle mechanism comprising: at least one vehicle axle; a gear mechanism connected to the vehicle axle; an electric motor that comprises a rotor and that is connected to the gear mechanism for transmitting a torque to the at least one vehicle axle; a position sensing device for ascertaining a rotor position of the rotor; an electronic power unit that is connected to the electric motor for supplying electrical energy to the electric motor, wherein the electronic power unit furthermore comprises an evaluating device for evaluating the signals of the position sensing device and is connected to an evaluating device that is embodied as a separate device, wherein the position sensing device is integrated at least in part in the electronic power unit or the evaluating unit.

Electric vehicle axle mechanism

Method for operating a hybrid drive, in particular a parallel hybrid drive, of a vehicle. The parallel hybrid drive includes an internal combustion engine and at least one electric drive, at least one energy storage device, and a vehicle transmission. During deceleration phases in which a torque required on the transmission input side is present, the internal combustion engine is operated either in drag mode or at a minimum drive torque.

Braking strategy for a hybrid drive of a vehicle

A method for consumption-optimized operation of an internal combustion engine of a motor vehicle is described, an engine output of the internal combustion engine being set as a function of a position of a gas pedal according to a manipulated variable, the gas pedal being adjustable in a first mechanically defined adjustment range between an initial position and a specific gas pedal position, the internal combustion engine being controlled with a consumption-optimized engine output with regard to the instantaneous engine speed by adjusting the gas pedal to the specific gas pedal position, the consumption-optimized engine output causing a minimal fuel consumption at the instantaneous engine speed.
