Abstract: An internal combustion engine is fluidly connected to an exhaust aftertreatment system and operatively connected to an electro-mechanical transmission to transmit tractive power to a driveline. The engine is controlled during an engine operating cycle by determining a temperature of the exhaust aftertreatment system and adjusting power output of the engine based upon the temperature of the exhaust aftertreatment system and a preferred temperature range of the exhaust aftertreatment system. The electro-mechanical transmission is controlled to transmit tractive power to the driveline to meet an operator torque request based upon the adjusted power output of the engine.

Abstract: A rotating mass component with high balancing quality is provided. The balancing is performed in a substantially automated manner and without chip formation.

Abstract: A preventatively acting safety system for a motor vehicle comprises safety devices which are actuated as a function of information which is recorded by a driving situation detection device by means of a driving state sensor system and is evaluated in a data evaluation device. The recorded information are compared with at least one triggering threshold value and the safety devices being actuated when the triggering threshold value is exceeded. The triggering threshold value is adapted as a function of a total vehicle acceleration and a vehicle speed, to correspond to a degree of danger felt by a vehicle occupant.

Abstract: A control method for vehicular hybrid powertrain system includes monitoring operator inputs to an accelerator pedal and a transmission gear selector, and determining an operator torque request based upon the operator inputs to the accelerator pedal and the transmission gear selector. Torque output from the electric machine is commanded based upon the operator torque request.

Engine coolant temperature is determined, and power output of the engine is adjusted based upon the coolant temperature and preferred coolant temperature range. The transmission is controlled to transmit tractive power to the driveline to meet an operator torque request based upon the adjusted power output of the engine.

The optical element includes a light passage opening pivotable into an optical axis of the light source. A beam of the light distribution is limited or deflected such that a limited light field is produced in a pre-settable region in front of the vehicle, which light field has an external form of the light passage opening. Further light passage structures provide a “high beam” or “partial high beam” light pattern and thereafter the “high beam” light pattern by turning, pivoting and/or displacing the optical element in one direction, and another further light passage structure provides a “motorway” and thereafter a “country road” light pattern by turning, pivoting and/or displacing the optical element in an opposite direction.
