Abstract: For an electrical unbalanced load of a vehicle having an at least partially electrified drive train with at least one high-voltage system, information about a value characterizing an energy quantity of a Y capacitor of the high-voltage system is determined. The information about the electrical unbalanced load is finally determined by comparing the determined characterizing value with a threshold value.

Abstract: A monitoring apparatus of an onboard electrical system of an at least partially electrically operated motor vehicle. A switchgear is configured to switch a high-voltage positive path and a high-voltage negative path of an electrical energy storage device of the onboard electrical system. The switchgear has a control line which is coupled to a pyrotechnic safety device. In an event of an interruption of the control line, the switchgear opens the high-voltage positive path and the high-voltage negative path. A control line switchgear is series-coupled in the control line to the pyrotechnic safety device. The control line switchgear interrupts the control line as a function of a control signal of an electronic computing device. The electronic computing device is configured to check a voltage potential in the control line using the control line switchgear before the electrical energy storage device is connected to the onboard electrical system.

Abstract: The invention relates to a method for determining a height (H) of a trailer (12) of a motor vehicle (10), in which at least one image of a ground area (22) of the motor vehicle (10) is recorded by means of at least one first optical recording device (14a, 14b) and in which the image is evaluated by means of an electronic computing device (20) of the motor vehicle (10), wherein a ground area (22a, 22b) to the side of the motor vehicle (10) is recorded, and a shadow boundary (G) of a shadow (24) of the trailer (12) on the ground area (22a, 22b) to the side is determined in the recording, and the height (H) is determined by means of the electronic computing device (20) as a function of a shadow length (L) of the shadow (24) relative to the motor vehicle (10). The invention also relates to an electronic computing device (20).

Abstract: A method for operating a vehicle includes carrying out a lane-keeping control of the vehicle along a course of a lane travelled in by the vehicle. When lane markings are detected, the course of the lane is determined on a basis of detected lane markings. When lane markings are not detected, the course of the lane is determined in a mapped-based manner on a basis of data from a digital map where a rough localization of the vehicle in the digital map and a fine localization of the vehicle in the digital map is performed.

Abstract: A method for automatically emergency stopping a motor vehicle from a starting speed to a standstill by a braking device of the motor vehicle is provided. The braking device is actuated to carry out a delay profile with at least two delay phases. During a delay increase phase the delay until a threshold delay is increased and during a delay decrease phase, lasting until standstill, the delay is reduced to zero. The temporal courses of the delay are determined during the delay increase and the delay decrease at least sectionally as nth degree polynomials, where n>0, depending on the starting speed, in such a way that a stopping duration, which represents a time duration necessary for emergency stopping, does not fall below a predetermined minimum stopping duration and a distance covered during the stopping duration does not exceed a predetermined maximum stopping distance.

Abstract: A method for operating a vehicle includes continuously checking during a driving operation whether an emergency situation is present in the vehicle and, when an emergency situation is detected, initiating an emergency stopping maneuver for safely parking the vehicle, signalling the emergency situation to a road user in a surroundings of the vehicle, and aborting the emergency stopping maneuver when a vehicle user takes over a task of driving the vehicle. The method further includes automatically deactivating the signalling of the emergency situation when an ascertained duration of time between the initiating and the aborting of the emergency stopping maneuver is smaller than a predeterminable time value and/or when an ascertained reduction of a driving speed of the vehicle between the initiating and the aborting of the emergency stopping maneuver is smaller than a predeterminable speed reduction value.
