Improvement method for fuel consumption in internal-combustion engine, involves recognition of driver, where comfort function is activated as function of result of driver recognition in motor control

摘要

The method involves recognition of a driver. A comfort function is activated as a function of the result of the driver recognition in the motor control (50). The comfort function is activated by comparing the firing angle with a reference firing angle, and the torque of the internal-combustion engine (10) is changed. The butterfly valve (38) is headed in a way such that a torque reserve is developed. An independent claim is also included for the device for the improvement of the fuel consumption in an internal-combustion engine in a vehicle.
