The embodiments disclose a method including separating kinetic speed from energy using a transmission platform, directing energy in the kinetic form at a predetermined speed from 0 to 100%, employing the transmission platform with fewer pieces to increase overall efficiency at a lower cost to produce, and integrating the transmission platform with combustion engines and electric motors to achieve more efficiency and greater performance.

When a first type gear shift line is used as a gear shift line to change the gear ratio, and a predetermined condition including a condition that a state of charge of the power storage device is equal to or lower than a first ratio is satisfied, the control device changes the gear shift line to a second type gear shift line that recommends a lower speed gear ratio than the first type gear shift line.

A method for operating an electrically operated or also electrically operable motor vehicle provided with a rechargeable electric energy storage device associated with the drive motor of the motor vehicle. A target charging state is determined for the energy storage device and an operating strategy is determined for a route that is calculated, entered or predicted for the next trip, by which recuperative deceleration is enabled with a specifiable minimum amount for deceleration processes occurring along the route. A total mass of the motor vehicle, including optionally a trailer connected to the motor vehicle, deviating from an input normal value and an air resistance of the motor vehicle deviating from a predetermined normal value are taken into account.

An electronic control unit is configured to select one of a series mode, a series-parallel mode and a parallel mode as a running mode. A load level of a hybrid vehicle is set to a value that is high in the order of a load level at which the parallel mode is selected, a load level at which the series-parallel mode is selected, and a load level at which the series mode is selected. That is, the electronic control unit selects the series-parallel mode in an intermediate load region, selects the series mode in a low load region, and selects the parallel mode in a high load region.

A vehicle provided with an electric propulsion system and a method for controlling the electric propulsion system are provided. The system includes a first Electrical Motor (EM1) connected via first Electrical Connections (EC1) to an on-board Energy Storage System (ESS1) and drivingly connected to wheels. The system further includes a second Electrical Motor (EM2) connected via second Electrical Connections (EC2) to one or several electrical energy sources and drivingly connected to wheels.
