Vehicle Telematics Wireless Device Connection Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles equipped with telematics units face challenges in managing multiple wireless devices, particularly in distinguishing between devices belonging to the driver and passengers, leading to difficulties in establishing preferred short-range wireless connections.
Innovation Solution
A method that detects multiple wireless devices using short-range communication protocols, presents their identities on a visual display, allows occupants to select preferred devices, and establishes communication links accordingly, prioritizing connections with devices in the preferred group.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle telematics unit connects with multiple wireless devices simultaneously, then the versatility and user experience are improved, but the difficulty of managing and distinguishing between devices increases
Solution Approach 1:
The patent segments wireless devices into distinct groups: preferred group (driver's device) and non-preferred group (passengers' devices). This segmentation allows the telematics unit to manage multiple devices simultaneously while reducing complexity by applying different connection rules to different segments. The visual display also segments device identities into grouped categories, making it easier for occupants to identify and select their preferred devices.
2Ease of operation
If the vehicle telematics unit automatically determines which device to connect with, then the ease of operation is improved, but the reliability of connecting with the correct preferred device decreases
Solution Approach 1:
The patent implements preliminary action by having occupants pre-assign their wireless devices to the preferred group before driving. The visual display presents device identities and allows occupants to select and assign their devices in advance. This preliminary assignment ensures that when multiple devices are present, the telematics unit can reliably connect with the correct preferred device without needing to make real-time automatic determination, thus maintaining both ease of operation and high reliability.
3Reliability
If the vehicle prioritizes connection with preferred devices, then the reliability of connection is improved, but the adaptability to accommodate multiple users decreases
Solution Approach 1:
The patent implements dynamics by making the connection priority system flexible and changeable. Occupants can dynamically re-assign their devices to the preferred group through the visual display interface. When a preferred device is unavailable, the system dynamically adapts by allowing connection with non-preferred devices. This dynamic capability ensures reliable connection preference while maintaining adaptability to accommodate multiple users and changing situations.

AI summary
A method of managing wireless devices at a vehicle includes detecting a plurality of wireless devices at the vehicle using a short-range wireless communication protocol; determining that one of the plurality of wireless devices belongs to a preferred group of wireless devices; and creating a short-range wireless link between the wireless device belonging to the preferred group and a vehicle telematics unit.
