Solution Overview
Problem
Current systems for displaying and managing content, such as television programming, lack efficient methods for users to conveniently select and find content, especially in vehicle environments where traditional interfaces may be limited.
Innovation Solution
A system and method that couples a mobile device or wearable device with an in-vehicle infotainment system to generate and communicate a vehicle position signal, allowing a user device to display the vehicle's location on a map, along with content selection and control capabilities through a user interface, enabling seamless content management and navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile device is coupled to an in-vehicle infotainment system to display vehicle location and content, then user convenience and content accessibility are improved, but device complexity and system integration requirements increase
Solution Approach 1:
The system divides functionality between the mobile device (user interface, content selection) and the in-vehicle infotainment system (vehicle position signal generation, map display). This segmentation allows each component to specialize in specific tasks, improving ease of operation while managing overall system complexity through clear functional boundaries.
Solution Approach 2:
The mobile device serves multiple functions: it acts as a remote control for content selection, a GPS receiver for vehicle location tracking, and a display device for showing both content information and map data. This multi-functionality consolidates several devices into one, improving convenience while the standard mobile device platform manages the complexity burden.
2Loss of information
If vehicle position tracking and map display are implemented on a user device, then user awareness of vehicle location is improved, but data communication requirements and system resource usage increase
Solution Approach 1:
The vehicle position signal generation function is extracted from the mobile device and implemented in the in-vehicle infotainment system. The mobile device only receives and displays this data, rather than continuously computing position data. This extraction reduces the energy consumption burden on the mobile device while ensuring continuous vehicle location information availability.
Solution Approach 2:
The system updates vehicle position information periodically rather than continuously, with the mobile device receiving position updates at intervals from the in-vehicle infotainment system. This periodic update approach maintains current location awareness while significantly reducing energy consumption compared to continuous real-time tracking and processing.
3Adaptability or versatility
If multiple devices (mobile device, wearable device, set top box) are integrated into the content delivery system, then content accessibility and user satisfaction are improved, but system complexity and coordination requirements increase
Solution Approach 1:
The in-vehicle infotainment system serves as an intermediary between the vehicle's native systems and external devices (mobile devices, wearable devices, set top boxes). It receives vehicle position data, processes content selection requests from various devices, and coordinates the display of both map and content information. This intermediary role simplifies integration by providing a standardized interface that multiple devices can connect to, enhancing versatility while managing coordination complexity centrally.
Data Source
AI summary
A system and method includes a mobile device having a mobile device identifier associated therewith and an in-vehicle infotainment system. The mobile device communicates the mobile device identifier to the in-vehicle infotainment system. A user device is controllable by inputs from a user though a user interface display associated with the user interface. A global positioning system generates a vehicle position signal at the vehicle. The user device is separate from the in-vehicle infotainment system and the global positioning system. The in-vehicle infotainment system communicates the vehicle position signal corresponding to a current vehicle position and the mobile device identifier to the user device. The user device is associated with a display displaying a map display comprising a map with a representation of the vehicle at the current vehicle position and the mobile device identifier of the mobile device.
