The invention relates to a method for operating a motor vehicle, in which by at least one ultrasonic sensor, operated in the active operation mode, of an ultrasonic sensor device of the motor vehicle ultrasonic waves are emitted into an environmental region of the motor vehicle, wherein the motor vehicle as hybrid vehicle is equipped with an internal combustion engine (and an electric drive machine and in the active operation mode of the ultrasonic sensor arranged on a rear part of the motor vehicle the motor vehicle at least temporarily is operated by means of the electric drive machine. The invention also relates to a motor vehicle.

Method for operating a motor vehicle and motor vehicle

The invention relates to a method for operating an ultrasonic sensor apparatus () of a motor vehicle (), in which method ultrasound waves are emitted into a surrounding region () of the motor vehicle () by at least one ultrasonic sensor () of the ultrasonic sensor apparatus () in order to carry out a distance measurement, wherein an exhaust gas cloud () which is emitted into the surrounding region () by an exhaust system () of the motor vehicle () and at which the ultrasound waves are reflected is detected by the ultrasonic sensor apparatus () on the basis of sensor data from at least one sensor () of the motor vehicle (), which at least one sensor is different from the ultrasonic sensor (), and the ultrasonic sensor apparatus () is operated depending on the detection of the exhaust gas cloud ().

A method is provided for assigning a time stamp to a specific data packet which, as with a group of received data packets, is received by a cyclically operating sensor. The specific data packet is especially part of the group of received data packets. The disclosed method includes: determining the time of arrival of each data packet of the group of received data packets; assigning a time stamp to each data packet of the group of data packets; determining the time difference between the determined time of arrival and the assigned time stamp for each data packet of the group of data packets; determining the smallest time difference from among the determined time differences; and assigning a time stamp to the specific data packet on the basis of the time of arrival determined for the data packet for which the smallest time difference has been determined.

Assigning time stamps to received data packets

A mobile unit as well as a method for time-stamping a first message of the first mobile unit to a second mobile unit are provided. The method includes the steps of: determining a roundtrip time between the first mobile unit and a base station, receiving the first message sent by the first mobile unit in the base station, adding a timestamp to the first message in the base station while taking into account the roundtrip time, and sending the time-stamped first message to the second mobile unit.

A method is provided for assigning a time stamp to a specific data packet which, as with a group of received data packets, is received by a cyclically operating sensor. The specific data packet especially is part of the group of received data packets. The method includes: determining the time of arrival of each data packet of the group of received data packets; assigning a time stamp to each data packet of the group of data packets based on a first reference point in time; determining the time difference between the determined time of arrival and the assigned time stamp for each data packet of the group of data packets to provide a group of time differences; determining negative time differences from among the group of time differences, for the data packets of which it has been determined that the time of arrival preceded the respective assigned time stamp; determining the negative time differences that are not to be classified as outliers; determining a second reference point in time taking into account the negative time differences that are not to be classified as outliers; and assigning a time stamp to the specific data packet based on the second reference point in time.
