Vehicle Voice Controller Automatic Activation via Operating Step
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operation of vehicle devices in modern vehicles, which often require complex interactions with multiple systems, can distract drivers and compromise safety due to the need for separate operating elements and voice controllers that are not seamlessly integrated, leading to potential safety risks during driving.
Innovation Solution
A method and apparatus that automatically activates a voice controller upon selecting an operating step, allowing both linguistic and haptic inputs for subsequent steps without requiring a separate push-to-talk button, and integrates voice control into the multi-functional operating device, with a limited vocabulary based on the current operating context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate operating elements are provided for each vehicle device, then each device can be operated independently and reliably, but the number of operating elements increases and the operation becomes complex and distracting
Solution Approach 1:
The patent implements a single multi-functional operating device that can operate multiple vehicle devices through different operating steps. The display device shows different operating steps for different functions (ventilation, temperature control, lighting, etc.), and a single operating element can select among these steps, eliminating the need for separate operating elements for each device while maintaining reliable operation of all functions.
2Ease of operation
If complex operating procedures are required for vehicle devices, then precise control can be achieved, but the driver's concentration is stressed and safety is compromised
Solution Approach 1:
The patent segments the operation into distinct operating steps that are displayed sequentially on the display device. Each operating step represents a specific function or sub-function, allowing the driver to operate devices in a structured, step-by-step manner rather than dealing with complex simultaneous controls. This segmentation makes operations more intuitive and reduces cognitive load.
Solution Approach 2:
The operating system dynamically adapts to driver input by providing both haptic and voice input options. The system can switch between different input modes based on the situation, allowing for quick haptic responses when needed and voice commands when the driver needs to keep hands on the wheel, thereby maintaining safety while enabling precise control.
3Measurement precision
If voice controller requires separate push-to-talk button activation, then voice recognition can be triggered intentionally, but the operation becomes less intuitive and more complex
Solution Approach 1:
The patent merges the voice controller activation with the main operating element. The same operating element that selects operating steps also activates the voice controller. When the operating element is in a state that allows voice input (as indicated on the display), the driver can simply speak without needing to press a separate push-to-talk button, making the voice control more intuitive while maintaining accurate voice recognition through contextual limitations.

AI summary
In a method for operating a device in a vehicle, an operating step is selected and a function associated with the operating step is performed. The operation of selecting the operating step automatically activates a voice controller for input following the operating step. An apparatus for operating a device in a vehicle has a display apparatus for displaying operating steps, a first operating unit for haptic input for selecting an operating step, a voice control unit for voice input for selecting an operating step, and a control unit which is coupled to the display apparatus, the first operating unit and the voice control unit and can be used to generate control signals for performing a function associated with a selected operating step. The control unit is designed in such a manner that the operation of selecting an operating step automatically activates the voice control unit for input following the operating step.
