Driving Support Device Voice Output Overlap Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic driving devices face challenges in effectively guiding drivers through voice output, as the timing of voice information with lower information value is often delayed, making the guidance less meaningful if not delivered promptly.
Innovation Solution
A driving support device and method that includes a processor to manage voice output instructions from both automatic driving and car navigation devices, ensuring that voice guidance is prioritized and supplemented with extended display, tactile feedback, sound effects, and monitoring state displays when their output timings overlap, thereby enhancing driver awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If voice output timing is delayed for information with lower information value, then voice information can be output in order of importance, but the voice guidance becomes meaningless if not output at the right point in time
Solution Approach 1:
The patent transitions from a single voice output channel to multiple output dimensions by displaying content on a display device when voice output timing overlaps. This adds a visual dimension to compensate for delayed or overlapping voice guidance, ensuring information is effectively transmitted without losing temporal precision.
Solution Approach 2:
The display device acts as an intermediary to deliver guidance information when voice output timing overlaps. Instead of losing guidance effectiveness due to timing conflicts, the system uses visual display as a mediator to ensure the driver receives the information in a timely and meaningful manner.
2Reliability
If multiple voice output requests are processed sequentially by information value, then important information is prioritized, but the system complexity increases to manage multiple output channels and timing coordination
Solution Approach 1:
The display device serves multiple functions: it displays content from both the automatic driving device and the car navigation device, and it provides alternative information delivery when voice output timing overlaps. This multi-functionality reduces the need for separate complex coordination systems for each output channel.
Solution Approach 2:
The system determines in advance whether voice output timing will overlap and prepares display content accordingly. By performing this timing check and content preparation beforehand, the system avoids complex real-time coordination and ensures reliable guidance delivery without increasing system complexity.

AI summary
A control device as a driving support device includes a processor configured such that the processor receives respective voice output instructions from an automatic driving device and a car navigation device provided in a vehicle, and when respective timings to output voice from the automatic driving device and from the car navigation device overlap with each other, the processor performs a control to display a content corresponding to a content of the voice output from the automatic driving device for a longer time than a time to display the content of the voice in a case where the timings do not overlap with each other.
