Method for operating a detection device of a motor vehicle

A method for operating a motor vehicle for a trip to a destination, the method comprising:

• locally determining, by a detection device based on sensor data of the motor vehicle and status data of at least one vehicle component, whether the motor vehicle is in a search phase during which a driver of the motor vehicle is no longer driving toward the destination but is searching for a parking opportunity for the motor vehicle;
• determining, by the detection device, a search duration of the search phase;
• determining, by at least one environmental sensor device of the motor vehicle during the determination of the search duration, environmental sensor data which describes at least one environmental condition and which are present during the search phase at the destination, the environmental sensor data including weather data and a time of day;
• communicating the environmental sensor data together with the determined search duration to a vehicle-external server device;
• and
• in the vehicle-external server device:
• collecting and analyzing the search duration and search duration data of other motor vehicles;
• generating statistical estimates that indicate a statistically expected estimated search duration for the parking opportunity within a destination region within which the destination lies by differentiating the collected search durations based on corresponding times of day, a day of the week, and the weather condition,
• wherein the statistical estimates are dependent on the time of day and the day of the week and the weather condition, and
• wherein the statistical estimates are determined as time data depending on a respective destination.
