Title:
METHOD FOR CONTROLLING A DRIVE TRAIN OF A MOTOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/072788
Kind Code:
A3
Abstract:
The invention relates to a method for controlling a drive train (1) of a motor vehicle, comprising an internal combustion engine (2), a gearbox (4), a friction clutch (5) which is effectively arranged between them and is operated in an automated manner, an electric starter (7), a generator (10) arranged in a belt pulley plane and at least one auxiliary unit (11), wherein the internal combustion engine (2) is shut down during a coasting operation and while the friction clutch (5) is open and is restarted at the end of the coasting operation by closing the friction clutch (5). In order to carry out a restart of the internal combustion engine in a robust, quick and comfortable manner after the coasting operation, the clutch torque (MK) is controlled to a predetermined adjustable clutch torque (MK1) when the coasting operation is completed, the generator (10) is operated in an electromotive manner as a function of an energy state of an electrical power supply of the motor vehicle or is shut down and the at least one auxiliary unit (11) is adjusted to a predetermined adjustable load which is reduced with respect to its original state, and, after a start of the internal combustion engine (2), the predetermined clutch torque (MK1) is increased, the generator (10) is operated as a generator as a function of the energy state of the power supply and the at least one auxiliary unit (11) is put into its original state.
