  • Patent number: 11208110
    Abstract: The disclosure relates to a method that models a motor vehicle sensor in a virtual test environment by way of definition. Using a sensor support, a raycast distribution shape, a group of raycast properties, a raycast reflection factor, and a raycast echo, a sensor in reality may be tested in a virtual environment to calibrate the sensor in reality. The sensor support is a virtual sensor support for a virtual sensor model, which forms a three-dimensional or two-dimensional avatar of the sensor in reality, in the virtual test environment. The sensor support has a sensor starting point that is used as an origin for a raycast distribution shape. The method extracts a special application of the sensor in reality in an application case, which is particularly useful for testing scenarios.

  • Publication number: 20190041866
    Abstract: A method for operating a motor vehicle and a lidar sensor system mounted to a motor vehicle. A lidar sensor mounted onboard the vehicle is operated to detect an object, and to read a nano-fingerprint on the object. The nano-fingerprint may be a passive and invisible structure that can be read out with a laser scanner as a nano-barcode, a nano-QR code, or similar. A detection module extracts, from the sensor data, position data related to the object. The position data may be used to calculate a velocity and/or acceleration of a moving object, such as a second vehicle. A scanning module extracts, from the sensor data, object data encoded in the nano-fingerprint and utilizes the object data to identify the object. A control unit controls operation (such as steering, braking, etc.) of the vehicle utilizing the position data and the object data.

    Abstract: A method to manage a parking area by a system in connection with the vehicle is provided. The system is designed to enter into connection with a vehicle that is looking for a parking space, and to assign a parking position to the vehicle. The system registers available parking room on the basis of an entropy calculation, wherein, within a parking area, both an a priori entropy prior to parking the vehicle and an a posteriori entropy are evaluated for a specific parking position, in order for a parking position to be assigned to the vehicle that brings about the lowest possible entropy on the parking area.
