A hybrid drive system for a motor vehicle includes an internal combustion engine and at least one electric motor, each driving wheels of the motor vehicle. The internal combustion engine is coupled to the corresponding wheels via a first multispeed transmission. The electric motor is coupled to the corresponding wheels via a second multispeed transmission.

Hybrid drive system

A method and a device for operating a vehicle having a hybrid drive are described, in which a first drive unit and a second drive unit contribute jointly or individually to the drive of the vehicle, the first drive unit driving the second drive unit in the manner of a generator for charging an energy storage device, the first drive unit and the second drive unit being separable by a drive train element transferring a torque of the first drive unit. In a method in which it is ensured that the vehicle may continue to drive safely even in the event of a defect in a drive train element between the first drive unit and the second drive unit, the torque portion used for charging the energy storage device is reduced to a minimum torque, while the torque excess, which is reduced in the event of a defect in the drive train element but still exceeds the minimum torque, is utilized to propel the vehicle.

Method and device for operating a vehicle having a hybrid drive

A method and a device are described for controlling an exhaust gas aftertreatment system for an internal combustion engine. A state variable is ascertained, which characterizes the state of the exhaust gas aftertreatment system. The temperature of the exhaust gas aftertreatment system is controlled as a function of the state of the exhaust gas aftertreatment system and/or of the internal combustion engine.

Method and device for controlling an exhaust gas aftertreatment system

The invention relates to an apparatus for dividing an entering gas flow into two split flows, each of which flows through a branch of a line system. A control element is provided, which executes a control motion about a shaft between a first position and a second position. The entering gas flow is divided continuously, by means of the adjustable control element, at a volumetric flow ratio, and at the same time the control element allocates a medium to be metered, whose infeed point is associated with the control element, to the split flows at a different ratio V.
