HMI Output Control for Vehicle Voice Information Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safe-driving support systems cause discomfort to occupants by interrupting or overlapping voice and visual route guidance information with safe-driving support information, leading to a negative user experience.
Innovation Solution
An information providing apparatus that includes an information communication acquiring unit, an operating state detecting unit, an information providing deciding unit, a route guidance unit, and an HMI output control unit, which determines whether to provide safe-driving support information and controls the output of voice and visual information to prevent overlap or interruption with route guidance information, ensuring timely and non-disruptive delivery of safe-driving support information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If safe-driving support information is provided by interrupting or overlapping route guidance information, then the safety support information can be delivered timely, but the occupant experiences discomfort
Solution Approach 1:
The HMI output control unit performs preliminary analysis to determine whether safe-driving support information and route guidance information will overlap in their output timing. By predicting the potential overlap before it occurs, the system can take preventive action by delaying the output of safe-driving support information until the route guidance information has finished, thus avoiding the discomfort of overlapping outputs while still ensuring safety information is delivered.
2Ease of operation
If safe-driving support information is delayed to avoid overlap with route guidance, then occupant comfort is maintained, but the timing of safety information delivery is postponed
Solution Approach 1:
The system dynamically adjusts the output timing of safe-driving support information based on real-time analysis of route guidance information output status. The HMI output control unit continuously monitors whether route guidance is currently being output and adaptively determines the optimal timing for safe-driving support information delivery, balancing occupant comfort with timely safety information delivery.
3Ease of operation
If the system monitors and controls output timing to prevent overlap, then occupant comfort is improved, but the system complexity increases
Solution Approach 1:
The HMI output control unit serves as an intermediary component that coordinates between the safe-driving support information provider and the route guidance unit. It receives output timing information from both sources, analyzes potential conflicts, and makes centralized decisions about when to output safe-driving support information. This intermediary approach consolidates the control logic in one place, managing the complexity rather than distributing it across multiple independent components.

AI summary
An information providing apparatus makes a decision, when an information providing deciding unit decides that driving support information is to be provided, as to whether the output of the voice information about the driving support information responding to a command from the information providing deciding unit and the output of the voice information about route guidance info nation responding to a command from a route guidance unit overlap each other or not, and controls, when they overlap each other, the output of voice information by an information providing output unit in such a manner as to prevent the output of the voice information about the driving support information from overlapping with the output of the voice information about the route guidance information.
