Patent number: 10148917Abstract: In order to recognize hazard areas and/or construction areas on a roadway, an environment sensor produces detected environment data regarding objects indicating the hazard areas and/or construction areas. A traffic light system is detected in the environment data, position data of the traffic light system is determined, an environment scenario is determined from the environment data and is compared with a reference model of the environment scenario. If the reference model does not indicate the presence of a traffic light system, or indicates a traffic light system having position data differing from the position data of the detected traffic light system, then it is concluded that the detected traffic light system is a traffic light system identifying a hazard and/or construction area.Type: GrantFiled: July 10, 2013Date of Patent: December 4, 2018Assignees: Conti Temic microelectronics GmbH, Continental Teves AG & Co. oHGInventors: Stefan Hegemann, Matthias Komar, Stefan Lueke

Patent number: 9829575Abstract: A sensor system detects objects in an environment ahead of a vehicle. The environment is represented by a predetermined fixed number of position points in an environment model. Initially and when no objects are detected, the position points may be distributed stochastically over the detection area of the sensor system. When objects are detected, the position points are re-distributed based on the detected objects, e.g. with a higher density of position points to represent the detected objects. Because the total number of position points is a predefined fixed number that remains constant, the processing, storage and transmission of the environment model involves a constant data volume and efficient use of memory and transmission bandwidth.Type: GrantFiled: June 27, 2013Date of Patent: November 28, 2017Assignees: Conti Temic microelectronic GmbH, Continental Teves AG & Co. oHGInventors: Stefan Hegemann, Ralph Grewe, Andree Hohm, Stefan Lueke

Patent number: 9783201Abstract: A method for an overtaking assistant for a vehicle is provided. The vehicle is equipped with environment sensing systems for detecting objects in the own and an adjacent lane on the sides and at the rear of the vehicle. The space in front of the vehicle is preferably detected by environmental sensors as well. Autonomous cutting into an adjacent lane is only initiated if a first vehicle is detected in the adjacent lane. The first vehicle is taken as a reference for a speed of vehicles in the passing lane. It is also assumed that a second vehicle that approaches the first vehicle fast in the same lane has detected the first vehicle and will adjust its speed to the speed of the first vehicle.Type: GrantFiled: March 11, 2014Date of Patent: October 10, 2017Assignee: Conti Temic microelectronic GmbHInventors: Stefan Heinrich, Stefan Hegemann, Marc Fischer
