Method for controlling an output torque of an electric variable transmission by battery power management
Abstract:
In a method for controlling an output torque of an electric variable transmission having an input coupled to a combustion engine and at least one electric motor that is at least feedable by a battery and able to recuperate energy into the battery, the battery power is limited to a maximum continuous battery power when the transmission is in a stationary operating point with a continuous revolution speed. The battery power is increased and limited to a maximum transient battery power that is greater than the maximum continuous battery power in a non-stationary operating point, upon a request for changing the gear-ratio (ratio between transmission input and output-speed) or upon a request for changing the transmissions output revolution speed.
