Abstract

A method for assisting a maneuvering procedure of a motor vehicle in a parking garage is disclosed, 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.

First claim

What is claimed is:

1. A motor vehicle for improved parking maneuvering in a parking garage, comprising at least:
one or more climate-dependent sensors for determining at least one distance from the motor vehicle to one or more objects in an environment of the motor vehicle; and
a controller, connected with the one or more climate-dependent sensors and adapted for communication with a vehicle-external parking processing circuit of the parking garage over a communication link; wherein
the controller is configured to receive climate-specific measured data of the parking garage from the vehicle-external parking processing circuit and to calibrate the one or more climate-dependent sensors based on the received climate-specific measured data; wherein the controller is configured to calibrate the one or more climate-dependent sensors by adapting one or more of a sensor sensitivity, at least one parameter of the sensor, and a transmission sound pressure of the sensor.

2. The motor vehicle of claim 1 , wherein the motor vehicle is further configured to, during the parking maneuvering in the parking garage, operate in an autonomous driving mode, in which autonomous driving mode the motor vehicle moves autonomously.

3. The motor vehicle of claim 1 , further comprising a position acquisition circuit, configured to determine a current position of the motor vehicle, wherein
the position acquisition circuit is furthermore configured to transmit the acquired current position of the motor vehicle to the vehicle-external parking processing circuit; and wherein
the received climate-specific measured data is associated with the current position of the motor vehicle in the parking garage.

4. The motor vehicle of claim 3 , wherein the controller is further configured to:
receive a predetermined parking position from the vehicle-external parking processing circuit; and to
based on the predetermined parking position, determine a trajectory from the current position of the motor vehicle to the predetermined parking position along which the motor vehicle is guided to the predetermined parking position.

5. The motor vehicle of claim 4 , wherein the controller is further configured to transmit the trajectory to the vehicle-external parking processing circuit and to receive the climate-specific measured data from the vehicle-external parking processing circuit, which climate-specific measured data is associated with measuring points along the trajectory.

6. The motor vehicle of claim 3 , wherein the position acquisition circuit comprises an odometry sensor and/or a steering wheel angle sensor.

7. The motor vehicle of claim 3 , wherein the position acquisition circuit is furthermore configured to determine the level of the parking garage on which the motor vehicle is located, wherein the position acquisition circuit comprises a tilt sensor to determine the level of the parking garage.

8. The motor vehicle of claim 1 , further comprising a position acquisition circuit, configured to determine a current position of the motor vehicle, wherein the controller is configured to position-associate the received climate-specific measured data with the current position of the motor vehicle and to calibrate the one or more climate-dependent sensors based on the position-associated climate-specific measured data.

9. The motor vehicle of claim 1 , wherein the one or more climate-dependent sensors comprise ultrasonic sensors.

10. A system for improved parking maneuvering of at least one motor vehicle in a parking garage, comprising:
a vehicle-external parking processing circuit, adapted for communication with at least one controller of the at least one motor vehicle; and

the vehicle-external parking processing circuit is configured to send a signal to the at least one controller to initiate calibration of one or more climate-dependent sensors of the at least one motor vehicle and to transmit at least some of the climate-specific measured data to the at least one controller for the calibration.

11. The system of claim 10 , wherein the one or more measuring sensors each comprise one or more of a temperature sensor and a humidity sensor.

12. The system of claim 10 , wherein the one or more measuring sensors are arranged in the parking garage at an installation height between 300 mm and 500 mm from the floor of the parking garage on which the at least one motor vehicle is drivable.

13. The system of claim 10 , wherein the vehicle-external parking processing circuit is further configured to:
receive a current position of the at least one motor vehicle in the parking garage;
determine climate-specific measured data that are associated with the current position of the at least one motor vehicle in the parking garage; and to
