摘要： A sensor system for sensing the environment of a motor vehicle having has an evaluation unit, wherein a grid-based environmental model is calculated and at least one discrete value of environmental data is assigned to each grid cell. Discretization is carried out by comparing the environmental data with at least one threshold value. At least one discrete value of the grid is preferably transmitted via a data transmission system to an evaluation or control unit in the vehicle.

摘要： A method and a device for determining the position of a vehicle, said method comprising the steps: recording sensor data from the ground over which the vehicle travels; extracting ground characteristics of the ground over which the vehicle travels from the recorded sensor data or from occupancy grids which are calculated on the basis of the sensor data; determining the current position of the vehicle on the basis of the extracted ground characteristics using a characteristic map.

摘要： 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.

摘要： The present disclosure relates to a device for measuring distance using a camera. The camera is movably arranged on a camera holder. A controller is designed to control a movement of the camera, in particular in a stationary state of the device, in such a manner that the camera records at least two images in at least two positions. A computing device is designed to calculate and output the distance of the device from objects visible on the images based on the at least two images. Further, the present disclosure discloses a vehicle and a method.
