Abstract: A battery reverse polarity protection circuit is disclosed. The battery reverse polarity protection circuit includes a field effect transistor (FET) coupled to a control circuit. The FET is configured to transmit an input voltage from a normal-polarity-connected battery to an output terminal, and block the input voltage from a reverses polarity-connected battery to the output terminal. The control circuit is coupled to the input terminal, the output terminal, and a common terminal and is configured to detect, during transmission of the input voltage from the normal-polarity-connected battery to the output terminal, that the input voltage is less than an output voltage, indicating onset of an abnormal operating mode, and turn off the FET to prevent the output voltage from being affected by the input voltage during the abnormal operating mode.

Abstract: A clean version of the amended Abstract is shown as follows: The invention relates to a method for recognizing a raised object on the basis of images in an environmental region of a motor vehicle, comprising: capturing a first image from a first camera and a second image from a second camera, transforming the first and second images into a common reference system, forming gradients over pixel values of pixels along gradient lines in the transformed first and second images, summing gradients along parallel summation lines to form a gradient sum, determining a first pair of the maxima of the gradient sum in the transformed first image and a second pair of the maxima of the gradient sum in the transformed second image, recognizing the raised object, if at least one distance between the maxima of the first pair in the transformed first image deviates from a distance of the maxima of the corresponding second pair in the transformed second image.

Abstract: The invention relates to a method for calibrating a camera system (7) of a motor vehicle (1). At least one camera (8-11) respectively sequentially generates camera images (21-28) from an environment (2) of the motor vehicle (1). A computing device (12) generates a virtual view (14) of the environment (2) from a virtual perspective from the camera images (21-28) by means of a projection (P). In traveling, the computing device (12) passes at least once a calibration cycle for each camera (8-11). Based on current projection parameters (30) of the projection (P), therein, camera images (23, 24) of the camera (9) are transformed. Motion vectors are determined from it. For at least one geometric characteristic of the motion vectors, a reference value is set. From a difference between the at least one geometric characteristic of the motion vectors and the respective corresponding reference value, an error value is determined. Depending on the error value, new projection parameters are determined (30).
