Publication number: 20190263390Abstract: An operating method for a power train of a hybrid vehicle having an internal combustion engine, an electric drive machine and a rechargeable electric energy storage unit configured to supply the electric drive machine with energy, includes controlling the power train in a zero emission mode in which the internal combustion engine is deactivated and in which the electric drive machine serves to drive the hybrid vehicle, and in an emission mode in which the internal combustion engine is operated in a fired operation. The method also includes determining, for a system initiated change of operating mode from the zero emission mode into the emission mode, a starting command for the internal combustion engine. The change of operating mode from the zero emission mode into the emission mode is blocked for one of a predefinable delay time, a predefinable quantity of energy extracted from the electric energy storage unit, or a predefinable travel distance.Type: ApplicationFiled: May 14, 2019Publication date: August 29, 2019Inventors: Eric Berger, Arthur Huelsmann, Daniel Mau, Ferdinand Wiesbeck

Publication number: 20190263394Abstract: A method of controlling a vehicle includes determining location, speed, and direction of travel of the vehicle. At least one vehicle condition is sensed. A desired trajectory for the vehicle is determined in response to the sensed vehicle condition. A center point of an artificial stiffness applied to a steering wheel of the vehicle is varied so that the desired trajectory becomes the center point of the artificial stiffness. The artificial stiffness applied to the steering wheel is increased in response to an initiated steering maneuver. An apparatus for controlling a vehicle includes a steering system for turning steerable vehicle wheels of the vehicle in response to rotation of a steering wheel of the vehicle. A first sensor senses a location, speed, and direction of travel of the vehicle. A second sensor senses at least one vehicle condition.Type: ApplicationFiled: August 28, 2017Publication date: August 29, 2019Inventor: Daniel E. Williams
