Abstract: A method for the closed-loop and/or open-loop control of a lateral guidance of a vehicle with the aid of a lane-keeping assist. In the process, a detection signal is read in which represents hands-off and/or hands-on driving of the vehicle. If the detection signal represents the hands-off driving, then a closed-loop control signal is provided for controlling the lateral guidance in closed loop. On the other hand, if the detection signal represents the hands-on driving, then an open-loop control signal is provided for controlling the lateral guidance in open loop.

Abstract: A method for monitoring a steering action of a driver of a vehicle. The method includes exerting an automated steering torque on a steering system of the vehicle, reducing the automated steering torque and detecting a movement of the steering system and/or a force of the steering system and/or a lateral movement of the vehicle in response to the reduction of the automated steering torque, to monitor the steering action of the driver.

Abstract: A method for situation-related steering assistance in a lane keeping assistant for a vehicle includes: importing a collision signal; ascertaining a correction signal for adapting an intervention torque for the lane keeping assistant, in order to provide a situation-related steering assistance in the lane keeping assistant. The collision signal represents information about a risk of collision during a lane change, and the correction signal is ascertained using the collision signal.

Abstract: A method for preparing and/or performing a steering intervention. The method includes detecting a traffic-influencing object and continuously recording object information, determining whether the object is tangential to a current trajectory of the vehicle, monitoring a lateral distance to the object or a predicted time available until a countersteering intervention is necessary before the object is reached. The method additionally includes checking whether the driver performs a countersteering intervention, for the case that the lateral distance or the available time falls below a first threshold value, of pilot controlling at least one actuator that influences the trajectory, so that a steering pretorque is applied if no steering intervention is performed by the driver, and triggering the steering actuator, so that a steering torque is applied to the steering, if the lateral distance or the available time additionally falls below a second threshold value.

Abstract: A method for compensating a steering wheel angle signal, which is subject to an offset, in a vehicle, includes: a filtering step; and a use step. In the filtering step, the steering wheel angle signal is filtered while the vehicle is traveling, using a filtering rule, in order to obtain a mean value of the steering wheel angle signal. The steering wheel angle signal is filtered if a lane and/or a roadway of the vehicle meets predetermined criteria. In the use step, the mean value is used to compensate the offset.

Abstract: A method for classifying measuring points of a point cloud ascertained by at least one sensor, in particular, a point cloud ascertained from a LIDAR sensor, a radar sensor and/or a camera sensor, via a control unit. Local surface vectors to adjacent measuring points are ascertained for each measuring point of the point cloud. For each local surface vector, respectively one angle is calculated between the local surface vectors with respect to a gravity vector. A maximal surface vector having a maximal angle with respect to the gravity vector and a standardized surface vector are ascertained for each measuring point of the point cloud based on the calculated angles. Each measuring point of the point cloud includes a standardized surface vector and/or includes a maximal surface vector having an angle with respect to the gravity vector above a limiting value being classified as a non-ground point.

Abstract: A method for ascertaining a range limit of a LIDAR device, due to environmental influences, by use of a control unit is provided. For ascertaining distances between the LIDAR device and at least one surface in a scanning area, beams are emitted into the scanning area by a transmitting unit of the LIDAR device, and beams that are reflected and/or backscattered from the scanning area are received by a receiving unit of the LIDAR device. The distances between the LIDAR device and the surface are computed based on the propagation times of the transmitted beams and of the reflected and/or backscattered beams. A range limit of a maximum possible range of the LIDAR device is ascertained based on a variance of the computed distances. Moreover, a control unit and a LIDAR device are provided.
