Abstract

A service station for vehicles of an autonomous vehicle fleet. The service station includes at least one service module that is designed to identify the dirtiness of at least one vehicle component of the vehicle. The service module also includes at least one mobile robot and/or a robot arm on which a tool is arranged for identifying dirtiness. The tool includes at least one optical sensor and preferably at least one light source and/or at least one vapor emitter.

First claim

The invention claimed is:

1. A service station for vehicles of an autonomous vehicle fleet, comprising:
at least one service module configured to receive and process information regarding a type and degree of dirt of at least one vehicle component of a vehicle of the vehicle fleet; and
at least one mobile robot apparatus, operatively coupled to the at least one service module, wherein the at least one mobile robot apparatus comprises a tool for identifying the type and degree of dirt of the at least one vehicle component, the tool being configured on the mobile robot apparatus, and wherein the tool comprises at least one light source configured to emit light of different wavelengths, and at least one optical sensor, wherein the at least one optical sensor is configured to utilize spatially resolved and frequency-resolved reflectance data across multiple spectral bands to detect the type and degree of dirt from a plurality of different dirt types based on wavelength-dependent variations in the spectral characteristics of light reflected from the at least one vehicle component,
wherein the at least one service module is configured to execute a control algorithm that analyzes the light reflections detected by the at least one optical sensor to determine cleaning parameters based on the identified type and degree of dirt, and is further configured to adjust at least one cleaning parameter, the at least one cleaning parameter comprising selecting a specific cleaning tool or cleaning chemical, based on the identified type and degree of dirt.

2. The service station of claim 1 , wherein the at least one optical sensor is configured to record at least one image signal of the at least one vehicle component of the vehicle.

3. The service station of claim 2 , wherein the at least one optical sensor is configured to detect a degree of reflection of at least one surface of the at least one vehicle component.

4. The service station of claim 1 , wherein the tool comprises at least one vapor emitter.

5. The service station of claim 1 , wherein the tool comprises at least one moisture sensor and/or air quality sensor.

6. The service station of claim 1 , further comprising a cleaning tool for performing interior cleaning of at least one vehicle component, the cleaning tool being configured on the mobile robot apparatus, wherein the cleaning tool comprises at least one of a vacuum cleaner nozzle, an upholstery brush and/or an applicator for applying cleaning agent.

7. The service station of claim 1 , further comprising a communication module configured to communicate with at least one of other vehicles of the autonomous vehicle fleet and/or a server of a fleet operator, wherein the communication module comprises:
a controller configured to process information regarding the type and degree of dirt on the at least one vehicle component of the vehicle for controlling the mobile robot apparatus and/or the tool,
wherein the communication module is configured to transmit a first message indicating the type and degree of dirt detected on the at least one vehicle component and to receive a second message comprising information regarding the type and degree of dirt on the at least one vehicle component.

8. A service station for vehicles of an autonomous vehicle fleet, comprising:
at least one mobile robot apparatus, comprising an optical tool for identifying a type and degree of dirt of at least one vehicle component, the optical tool comprising at least one light source configured to emit light of different wavelengths and at least one optical sensor, and wherein the optical tool is configured on the mobile robot apparatus, wherein the at least one optical sensor is configured to utilize spatially resolved and frequency-resolved reflectance data across multiple spectral bands to detect the type and degree of dirt from a plurality of different dirt types based on wavelength-dependent variations in the spectral characteristics of light reflected from the at least one vehicle component;
at least one service module, operatively coupled to the at least one robot apparatus, configured to process the type and degree of dirt of the at the least one vehicle component of a vehicle of the vehicle fleet,
wherein the at least one service module is configured to execute a control algorithm that analyzes the light reflections detected by the at least one optical sensor to determine cleaning parameters based on the identified type and degree of dirt, and is further configured to adjust at least one cleaning parameter, the at least one cleaning parameter comprising selecting a specific cleaning tool or cleaning chemical, based on the identified type and degree of dirt; and
a cleaning tool, operatively coupled to the at least one service module, wherein the at least one service module is configured to carry out a cleaning action based on the selected cleaning parameters.

9. The service station of claim 8 , wherein the at least one optical sensor is configured to record at least one image signal of the at least one vehicle component of the vehicle, wherein the at least one optical sensor is further configured to detect a degree of reflection of at least one surface of a vehicle component.

10. The service station of claim 8 , wherein the optical tool comprises at least one vapor emitter.

11. The service station of claim 8 , wherein the optical tool comprises at least one moisture sensor and/or air quality sensor.

12. The service station of claim 8 , further comprising a cleaning tool for performing interior cleaning of at least one vehicle component, the cleaning tool being configured on the mobile robot apparatus, wherein the cleaning tool comprises at least one of a vacuum cleaner nozzle, an upholstery brush and/or an applicator for applying cleaning agent.

13. The service station of claim 8 , further comprising a communication module configured to communicate with at least one of other vehicles of the autonomous vehicle fleet and/or a server of a fleet operator, wherein the communication module comprises a controller configured to identify the type and degree of dirt of at least one vehicle component of the vehicle and for controlling the mobile robot apparatus and/or the optical tool.

14. A method for using a service station and preparing at least one vehicle component for cleaning for vehicles of an autonomous vehicle fleet, the method comprising:
receiving and processing, by at least one service module of the service station, information regarding a type and degree of dirt of at least one vehicle component of a vehicle of the vehicle fleet; and
utilizing, by at least one mobile robot apparatus, operatively coupled to the at least one service module, a tool configured on the mobile robot apparatus to identify the type and degree of dirt of the at least one vehicle component, wherein the tool comprises at least one light source configured to emit light of different wavelengths, and at least one optical sensor;
detecting, via the at least one optical sensor, the type and degree of dirt from a plurality of different dirt types utilizing spatially resolved and frequency-resolved reflectance data across multiple spectral bands comprising wavelength-dependent variations in the spectral characteristics of light reflected from the at least one vehicle component; and
executing, via the at least one service module, a control algorithm that analyzes the light reflections detected by the at least one optical sensor to determine cleaning parameters based on the identified type and degree of dirt, and adjusting at least one cleaning parameter, the at least one cleaning parameter comprising selecti
