Method For Controlling A Drivetrain For A Hybrid Vehicle
First Claim
1. A method for controlling a drivetrain of a hybrid vehicle, the drivetrain having at least one internal combustion engine, a torque converter and an operational link to at least one drivable axle, an electrical energy store, and an electrical machine usable as a generator for charging the electrical energy store during a recuperation operation, the method comprising the acts of:
- providing the electrical machine on a pump wheel of the torque converter and the operational link on a turbine wheel of the torque converter;
introducing a torque from the at least one drivable axle, via the operational link and through the turbine wheel, into a liquid of the torque converter in recuperation operation; and
dissipating the introduced torque in the liquid of the torque converter as heat.

Abstract
A method for controlling a drivetrain for a hybrid vehicle is provided. The drivetrain has at least one internal combustion engine, a torque converter and an operational link to at least one drivable axle, an electrical energy store, and an electrical machine, which is usable as a generator for charging the electrical energy store during a recuperation operation. The electrical machine is provided on the pump wheel and the operational link being provided on the turbine wheel of the torque converter. A torque is introduced from the drivable axle via the operational link and through the turbine wheel into the liquid of the torque converter in recuperation operation in order to be dissipated as heat.
