Method For Assisting A Maneuvering Procedure Of A Motor Vehicle, And System For Assisting A Maneuvering Procedure Of A Motor Vehicle

Abstract

The invention relates to a method for assisting a maneuvering procedure of a motor vehicle in a parking garage, wherein the motor vehicle moves within the parking garage during the maneuvering procedure from a drop-off site in the parking garage to a predetermined position in the parking garage, wherein the maneuvering procedure of the motor vehicle is monitored by at least one sensor of the motor vehicle, comprising the steps: establishing a communication link between a controller of the motor vehicle and a vehicle-external unit of the parking garage; transmitting climate-specific measured data that are acquired by at least one measuring point in the parking garage from the at least one measuring point to the vehicle-external unit, and calibrating the at least one sensor of the motor vehicle depending on the climate-specific measured data.

What is claimed is:

 establishing a communication link between a controller of the motor vehicle and a vehicle-external unit of the parking garage;   transmitting climate-specific measured data, that are acquired by at least one measuring point in the parking garage, from the at least one measuring point to the vehicle-external unit;   calibrating the at least one sensor of the motor vehicle depending on the climate-specific measured data.   
     
     
         2 . The method according to  claim 1 , wherein during the maneuvering procedure, the motor vehicle is in an autonomous driving mode, wherein the motor vehicle moves autonomously from the drop-off site to the predetermined position during the maneuvering procedure. 
     
     
         3 . The method according to  claim 1 , wherein a current position of the motor vehicle is determined during the maneuvering procedure, and the current position of the motor vehicle is transferred to the vehicle-external unit, wherein the climate-specific measured data acquired by the at least one measuring point is assigned to the current position of the motor vehicle. 
     
     
         4 . The method according to  claim 3 , wherein the climate-specific measured data acquired by the measuring points are assigned by the vehicle-external unit to the current position of the motor vehicle and transferred to the motor vehicle. 
     
     
         5 . The method according to  claim 3 , wherein the vehicle-external unit transfers the climate-specific measured data acquired by the measuring points to the motor vehicle, and the controller of the motor vehicle assigns the climate-specific measured data to the current position of the motor vehicle. 
     
     
         6 . The method according to  claim 1 , wherein the predetermined position is determined by the vehicle-external unit and transferred to the motor vehicle, in particular the controller of the motor vehicle, wherein based on the predetermined position, the controller determines a trajectory from the drop-off site to the predetermined position along which the motor vehicle is guided to the predetermined position. 
     
     
         7 . The method according to  claim 1 , wherein when calibrating the at least one sensor, a sensor sensitivity and/or at least one parameter of the sensor, in particular a transmission sound pressure of the sensor, is adapted. 
     
     
         8 . A system for assisting a maneuvering procedure of a motor vehicle in a parking garage, wherein the motor vehicle moves within the parking garage during the maneuvering procedure from a drop-off site in the parking garage to a predetermined position in the parking garage, wherein at least one sensor of the motor vehicle is configured to monitor the maneuvering procedure of the motor vehicle, comprising:
 a controller of the motor vehicle that is configured to establish a communication link to a vehicle-external unit in the parking garage;   at least one measuring point in the parking garage that is configured to acquire climate-specific measured data and transmit said measured data to the vehicle-external unit; wherein   the controller of the motor vehicle is furthermore configured to calibrate the at least one sensor of the motor vehicle depending on the climate-specific measured data.   
     
     
         9 . The system according to  claim 8 , wherein the at least one measuring point has at least one temperature measuring device and/or at least one humidity measuring device. 
     
     
         10 . The system according to  claim 8 , wherein the at least one measuring point in the parking garage is arranged at an installation height between 300 mm and 500 mm from the floor of the parking garage on which the motor vehicle moves. 
     
     
         11 . The system according to  claim 8 , wherein the drop-off site is located in an area of the parking garage, segregated from the remaining parking garage, wherein the parking garage is designed as a parking garage that is closed to the environment, wherein the measuring points are located within the segregated area. 
     
     
         12 . The system according to  claim 8 , wherein the system furthermore has an acquisition apparatus that is configured to acquire a current position of the motor vehicle, wherein the acquisition apparatus is furthermore configured to transmit the acquired current position of the motor vehicle to the vehicle-external unit. 
     
     
         13 . The system according to  claim 12 , wherein the acquisition apparatus for acquiring the current position of the motor vehicle has an odometry sensor and/or a steering wheel angle sensor. 
     
     
         14 . The system according to  claim 12 , wherein the acquisition apparatus is furthermore configured to determine the level of the parking garage on which the motor vehicle is located, wherein the acquisition apparatus has an tilt sensor of the motor vehicle to determine the level of the parking garage.
