Abstract: A method for calibrating an elevation angle of an ultrasonic sensor of an ultrasound-based driver assistance system of a vehicle.

Abstract: A method for calibrating an ultrasonic sensor of an ultrasound-based driver assistance system of a vehicle. The vehicle is placed on a ground. The method includes: a) prespecifying a height of the ultrasonic sensor from the ground or ascertaining the height of the ultrasonic sensor from the ground; b) emitting a number of ultrasonic pulses, wherein each ultrasonic pulse is emitted to form a main lobe and a side lobe, and the emission takes place such that the side lobe is directed toward the ground; c) detecting a plurality of side-lobe ground echoes; d) ascertaining and storing a correction value for detecting an elevation angle with the ultrasonic sensor and/or ascertaining and storing a correction value for detecting an azimuth angle with the ultrasonic sensor based on a number of the plurality of side-lobe ground echoes detected in step c).

Abstract: Methods for testing a control unit of a vehicle. The control unit obtains calculated surrounding-area data of a simulated surround sensor, and obtains calculated motion data of a simulated vehicle. The calculated motion data are transmitted to the control unit via a simulated vehicle data bus. Using a sensor testing unit, the calculated surrounding-area data are transmitted to the control unit via a sensor-data transmission circuit different from the vehicle data bus. To execute a simulated acquisition of surrounding-area data, using the control unit, a command for executing a measurement is transmitted to the sensor testing unit, data for identifying the position of the simulated surround sensor is transmitted to the computer device, positions of points of reflection by simulated objects in the surrounding area of the vehicle are calculated and transmitted to the sensor testing unit, and calculated surrounding-area data are determined and transmitted to the control unit.

Abstract: A portable barbecue unit mounted on wheels in the form of a rectangular shaped housing, open to the top, with a grill detachably mounted on a pair of external vertically slidable members that are pivotally mounted to a handle structure extending from an end of the housing. The handle structure is pivotally mounted to the housing through slots in the handle arms so that the grill may be elevated by downward manual pressure on the handle and tilted as desired with respect to the horizontal plane. A slidable tray is mounted beneath a grate in the housing, with the tray serving to catch ashes. A pair of shelf members are slidably mounted to the bottom of the housing to form opposed shelves when each is extended beyond the respective end of the housing.
