In-Vehicle Speaker Audio Control via Mobile Device Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles, incoming calls to mobile devices can distract users and reduce the audio experience for other occupants due to the need for manual volume adjustments, which is frustrating and disrupts the audio experience for all passengers.
Innovation Solution
An in-vehicle computing system that detects the location of a mobile device and automatically adjusts the audio settings of nearby speakers to reduce distractions for the user receiving a call, while maintaining the audio experience for other occupants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If audio is played back via a speaker corresponding to the location of the occupant receiving a phone call, then the audio experience for that occupant is improved, but the ability of the occupant to listen to and participate in the received call deteriorates
Solution Approach 1:
The system applies different volume levels to different speakers based on their spatial relationship with the mobile device. Speakers closer to the mobile device receiving a call have their volume reduced, while speakers farther away maintain or increase their volume. This local differentiation allows occupants in different locations to have optimized audio experiences without interfering with each other.
2Object-affected harmful factors
If the volume of speakers is manually adjusted when an incoming call is detected, then the ability of the occupant to listen to the call is improved, but the ease of operation deteriorates due to the need for manual intervention
Solution Approach 1:
The audio system automatically detects when a mobile device receives an incoming call and autonomously adjusts the volume of speakers without requiring manual intervention. The system uses location information to identify which speakers to adjust and applies appropriate volume levels automatically, eliminating the need for occupants to manually control the audio system during calls.
3Object-affected harmful factors
If the volume of all speakers is reduced when an incoming call is detected, then the ability of the occupant to listen to the call is improved, but the audio experience for other occupants deteriorates
Solution Approach 1:
Instead of uniformly reducing the volume of all speakers, the system selectively adjusts only the speakers that are closest to the mobile device receiving the call. Other speakers maintain their original volume levels or are adjusted minimally, ensuring that occupants in different locations experience appropriate audio levels tailored to their specific spatial context.
4Speed
If location information is continuously monitored to enable automatic speaker adjustment, then the responsiveness of the system to incoming calls is improved, but the use of energy deteriorates
Solution Approach 1:
The system establishes location information for mobile devices in advance before incoming calls occur. By having the mobile device's location pre-determined and stored, the system can immediately respond to incoming calls without needing to continuously monitor location changes in real-time, thereby reducing energy consumption while maintaining rapid responsiveness.

AI summary
Embodiments are disclosed for an in-vehicle computing system for selectively adjusting audio settings for speakers in a vehicle. In some embodiments, an in-vehicle computing system for a vehicle includes a processor, an external device interface communicatively coupleable to a mobile device, and a storage device storing instructions executable by the processor to receive an indication of an incoming call directed toward the mobile device. The instructions are further executable to determine location information for the mobile device, correlate the mobile device with a selected speaker of the vehicle, the selected speaker being associated with the location information for the mobile device, and adjust, via the in-vehicle computing system, at least one audio setting for the selected speaker.
