Publication number: 20180170380Abstract: A lane-keeping assistance device for monitoring the lane keeping of a motor vehicle includes an evaluation mechanism for evaluating at least one bend of lanes, located in front of the vehicle. The evaluation mechanism predefines a tolerance threshold value, which defines the maximum deviation limit of a transverse deviation of the motor vehicle from the motor vehicle's own lane. The evaluation mechanism is configured to adapt the tolerance threshold value in such a way that the intersection of an adjacent lane by the own lane in the at least one evaluated bend is tolerated.Type: ApplicationFiled: February 18, 2018Publication date: June 21, 2018Applicant: Conti Temic microelectronic GmbHInventor: Günter Anton Fendt

Publication number: 20180170382Abstract: An expanded powertrain interface and strategy for an autonomous driving controller to control powertrain torque (or vehicle acceleration/deceleration) capability at the current operating point, in addition to capability for subsequent operating points at a future time based on predictive assessment of powertrain energy management, subsystem contraints/limits, and capability in the future. The powertrain interface and strategy applies to a vehicle with electrified powertrain control (hybrid electric vehicle (HEV) or pure battery electric vehicle (BEV)) with an autonomous driving (AD) capability (either full or semi-automated driving). This powertrain interface and strategy may also be used with non-electrified powertrain (conventional) systems based on available combustion engine torque at the target vehicle speed and gear.Type: ApplicationFiled: March 20, 2017Publication date: June 21, 2018Applicant: Continental Automotive Systems, Inc.Inventors: Ihab Soliman, Brian McKay
