Method for operating hybrid vehicle, involves using eco-switching program, when first state is active, where eco-switching program executes circuits in transmission to ensure fuel-efficient driving style of hybrid vehicle

摘要

The method involves controlling or regulating the operation of the transmission (5) based on three states and based on the transition conditions between the states. An eco-switching program is used, when a first state is active, where the eco-switching program executes circuits in the transmission to ensure fuel-efficient driving style of the hybrid vehicle. A downshift in the transmission is prevented, when the third state is active, and is boosted, if required, at a maximum possible engine torque by an electric machine (2). An independent claim is included for a control device for a hybrid vehicle.
