Abstract: A method controls the operation of an electric motor. Wherein electrical voltages applied to electrical phases of the electric motor are produced and output in a controlled manner in a modulation on the basis of a rotor position of the electric motor, on the basis of a set point/actual comparison, which is performed in a control loop with a speed controller, for a speed of the electric motor and on the basis of a set point/actual comparison. A set point value at the input of the current regulator is formed by multiplying a present duty factor for the modulation by a first manipulated variable applied to the output of the speed controller. The first manipulated variable of the speed controller becomes an equivalent phase current root mean square value for the electric motor in the underlying current regulator by the multiplication by the present duty factor.

Abstract: A camera surround view system for a vehicle includes at least one vehicle camera, which provides camera images. The camera images are processed by a data processing unit in order to produce a live video image stream, which is displayed on a display unit. The camera surround view system loads local cloud information data regarding an object shown in the live video image stream from a data network and displays the obtained local cloud information data as an overlay in the displayed live video image stream.

Abstract: In a method for determining a depth map from stereo images, the disparity for a pixel is selected from a predefined quantity or set of predefined discrete disparity values that are distributed over the entire predefined disparity value range, whereby the distribution is non-uniform or has at least two different distances or intervals between different adjacent disparity values. This method makes it possible to more precisely determine (with finer resolution) especially only those disparities for which a more precise determination is required.

Abstract: A method for adapting a dead time between the beginning of ab opening process of a first switching element and the beginning of a closing process of a second, serially connected switching element in a switching regulator of a switching power supply unit. The method includes the following steps: a measurement voltage across the second switching element is measured, and the dead time is varied such that the deviation of the measured measurement voltage from a target value of the measurement voltage is minimized or limited. The first and second switching elements are actuated using the thus ascertained dead time. There is also described a device for carrying out such a method. The device includes a measuring unit, a processing unit, and a control unit.

Abstract: In a braking maneuver using a braking assistant (9) in a motor vehicle (3), the braking assistant (9) initiates an automatic braking maneuver when an actual distance (a) between the motor vehicle (3) and an object (5) located ahead of the motor vehicle (3) becomes less than a specified minimum distance (amin). Then an acceleration of the decelerating vehicle (3) is ascertained during the braking maneuver, and if the acceleration is positive then the braking maneuver initiated by the braking assistant (9) is automatically interrupted.

A first image area that includes an image of the road surface is determined in the at least one image.

Information regarding this specific road condition is output.

Abstract: In order to recognize hazard areas and/or construction areas on a roadway, an environment sensor produces detected environment data regarding objects indicating the hazard areas and/or construction areas. A traffic light system is detected in the environment data, position data of the traffic light system is determined, an environment scenario is determined from the environment data and is compared with a reference model of the environment scenario. If the reference model does not indicate the presence of a traffic light system, or indicates a traffic light system having position data differing from the position data of the detected traffic light system, then it is concluded that the detected traffic light system is a traffic light system identifying a hazard and/or construction area.

Abstract: A method and a device for determining a warning condition on the basis of brake light detection. Image data are received from a front camera of a vehicle. It is determined whether a brake light of a preceding vehicle is active. An initiation threshold is lowered or a confidence value is raised if the brake light is active. An estimated risk value is derived from the image data of the front camera and a warning signal is produced, if the estimated risk value exceeds the initiation threshold.
