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
