  • Patent number: 11400857
    Abstract: A high-beam assistance system of a motor vehicle determines whether or not an unseen vehicle with headlamps switched on is approaching from the opposite direction before the unseen vehicle enters the field of view of a camera in the host vehicle. Wherein the registered images do not include any approaching vehicle on the roadway, the high-beam assistance system determines an expected illumination information item which is estimated to result from illumination by the host headlamps, determines an actual illumination information item contained in the registered images, and compares the expected illumination information item and the actual illumination information item. If the actual illumination information item deviates from the expected illumination information item, then the illumination provided by the host headlamps is adjusted from a high-beam state to a low-beam state.

  • Publication number: 20220048532
    Abstract: A motor vehicle (2) is operated in conjunction with a barrier assembly (e.g., a passing gate). After reading an environment data record (UDS) from environment sensors (14) of the motor vehicle (2), the environment data record (UDS) is evaluated for an approach to a barrier assembly (4). A stopping data record (SDS) is determined which is indicative of a stopping position of the motor vehicle (2) in front of the barrier assembly (4). An interaction data record (IDS) associated with the barrier is determined which is indicative of an interaction with the barrier assembly (4) such as opening a driver window.

  • 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: 20210354685
    Abstract: A driver assistance system for a motor vehicle performs a maneuver using a trajectory determined according to an external environment. The vehicle has a plurality of environment sensors and a controller device configured to acquire an environment data set (UDS) using the environment sensors, which it transmits to a cloud computer. The cloud computer reads in the environment data set (UDS), generates a supplemental data set (EDS) for supplementing the environment data set (UDS), combines the environment data set (UDS) with the supplemental data set (EDS) in order to generate a supplemented environment data set (UDS?), and transmits the supplemented environment data set (UDS?) to the controller device. The supplemental data set (EDS) may be obtained by evaluating data of other road users within a predetermined radius of the vehicle. The controller device evaluates the supplemented environment data set (UDS?) for the purpose of controlling the trajectory.

  • Publication number: 20210061264
    Abstract: A method for performing automatic valet parking, which includes selecting a road scenario applicable to a roadway; notifying a driver to release manual control elements of a motor vehicle and to leave the motor vehicle; checking whether the control elements have been released and the driver has left the motor vehicle and, in this case, entering an EXPLORE mode in which the motor vehicle is slowly driven autonomously and searches for a free car space or a parking space using the vehicle's own environmental sensors, before the motor vehicle is placed in a parking position; and then to change from the EXPLORE mode to a PARKING mode in which the motor vehicle is parked in the car space or in the parking space from the parking position by means of the longitudinal and lateral controllers and using the environmental data previously obtained from the environmental sensors in the EXPLORE mode.
