Abstract: A method for operating a braking system for a vehicle. A braking request signal characterizing a braking request is generated by actuation of a positioning assemblage of an actuation circuit, and a target brake pressure required in an active circuit is ascertained based on the braking request signal. An actual brake pressure in the active circuit is established in accordance with the target brake pressure, using a pressure generation device, by moving a displacer piston of the pressure generation device using an electric motor of the pressure generation device. If the braking request signal is constant over a predetermined time period, a wheel brake actuated by the active circuit is hydraulically decoupled from the pressure generation device by closing an isolation valve that is disposed in a hydraulic path between the pressure generation device and the wheel brake, and the electric motor is shut off.

Abstract: A method for improving the estimation of an existence probability of objects. The objects are detected using sensors installed in a vehicle and/or an infrastructure component. Each tracker of a sensor and/or a sensor group estimates a status of an object and its existence probability using a detection probability model. The detected objects are merged in a fusion list, and each object is assigned a state and an existence probability. Each object of the fusion list is assigned existence probabilities. Each object of the fusion list is assigned additional information indicating which sensor and/or which sensor group has/have detected the respective object in the last measuring cycle. At least sensor-specific and/or sensor-group-specific existence probabilities of fused existence probabilities and the sensor detection probability are compared in a crosscheck, and false negative cases and false positive cases are ascertained for each sensor and/or sensor groups.

Abstract: A virtual visor system includes a visor having a plurality of independently operable pixels that are selectively operated with a variable opacity. A camera captures images of the face of a driver or other passenger and, based on the captured images, a controller operates the visor to automatically and selectively darken a limited portion thereof to block the sun or other illumination source from striking the eyes of the driver, while leaving the remainder of the visor transparent. The virtual visor system advantageously snaps projected eye positions on the visor to a grid, which helps to minimize rapid and distracting changes in the optical state of the visor.

Abstract: A method for determining a switching point of a solenoid valve. A solenoid coil is energized to raise a solenoid armature to unblock a flow opening. For a signal profile characteristic of a current profile in the solenoid coil, multiple periods each different from one another and each having the same predefined temporal length are determined. Within each period, a minimal and a maximal value of the signal profile and associated points in time are ascertained and a product of a difference between the maximal and minimal value and a difference between the associated points in time are ascertained. On the basis of the points in time of the minimal and maximal value of that period, which corresponds to a maximal value of the product, the switching point is determined.
