Operating device for electronic device functions in a motor vehicle

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to an operating device for controlling electronic functions in a motor vehicle. The device allows users (primarily drivers, but also passengers) to operate vehicle systems using a touch-sensitive graphical interface (touchscreen) and a voice-controlled acoustic interface. The system intelligently manages interactions, allowing the user to choose between or combine touch and voice control, providing feedback via both display and loudspeaker. A function key activates voice control, and special design ensures minimized driver distraction and maximized flexibility.

Use CasesContent extracted from patent full text and abstract with AI.

• Controlling in-vehicle entertainment systems (radio, MP3 player) via touch or voice
• Operating navigation systems with either voice commands or touchscreen input
• Hands-free operation of communication tools such as phone calls, text messaging, or emails in the car
• Passengers operating vehicle functions (e.g., climate control) while driver remains focused on the road
• Adaptive feedback for users through audio and/or visual means based on user preference and driving conditions
• Integration into mobile devices (e.g., smartphone used as vehicle control unit)
• Enhanced usability for expert users by direct menu navigation through voice

BenefitsContent extracted from patent full text and abstract with AI.

• Greatly reduces driver distraction by allowing hands-free and eyes-optional operation
• Adaptive, multimodal system lets users alternate between touch and voice as needed
• Provides both visual and auditory feedback, increasing user trust and operational clarity
• Can be flexibly installed as a fixed unit, modular add-on, or mobile device
• Enables user-driven (not system-driven) operation that adapts to real-time needs and attention demands
• Permission-based voice activation prevents accidental triggers and eliminates constant open microphone issues
• Improves safety in the vehicle by keeping the driver's focus on the road
• Allows passengers to participate in system operation, increasing convenience
• Supports advanced functions like text-to-speech for dynamic spoken feedback

Patent Abstract

The device has a graphical user interface with a touch-sensitive display (2) and an interpretation unit (3) interpreting user inputs received by the display. An acoustic user interface is activated by a driver by using a function key (8). A control device (1) has a processing unit for processing program statements and data stored in memory units. Operating process of an electronic device is executed by the acoustic or graphical user interface, where the operating device outputs system responses over the display and a loudspeaker (5) in two operating modes of the operating device.
