In-Vehicle Notification Mediator for Mobile Head Unit Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current infotainment systems lack a notification mechanism for services requiring notifications, such as call information, message information, or device state information, between mobile devices and in-vehicle head units, limiting user convenience.
Innovation Solution
A method and system for providing an in-vehicle notification service that includes receiving notification messages, generating action requests, and displaying Graphical User Interfaces (GUIs) on both mobile devices and head units, enabling unidirectional or bidirectional notification of events like calls, messages, and device status alarms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If infotainment systems provide various types of information to satisfy user demands, then user convenience is improved, but no notification mechanism has been specified for services requiring notification
Solution Approach 1:
The patent introduces a notification mechanism that acts as an intermediary between the mobile device and the in-vehicle head unit device. This mediator enables structured communication by defining specific message formats (notification messages, action request messages, GUI transmission messages) that facilitate the transmission of call information, message information, and device state information without requiring complex custom implementations at each endpoint.
2Loss of information
If notification mechanism is implemented between mobile device and head unit device, then notification of call information, message information, and device state information is enabled, but system complexity increases
Solution Approach 1:
The notification mechanism is segmented into distinct message types and transmission stages: (1) notification messages containing event information from the mobile device, (2) action request messages requesting application execution based on event type, and (3) GUI transmission messages for displaying notifications. This segmentation allows each component to handle specific tasks independently, reducing overall system complexity while ensuring comprehensive information transmission.
Solution Approach 2:
The patent utilizes parameter changes in message structures to convey different types of information. By varying the content and format of messages based on event types (call, message, device state), the system efficiently transmits diverse information through a unified communication framework without requiring separate protocols for each notification type.

AI summary
A method for providing an in-vehicle notification service on a head unit device is provided. The method includes receiving a notification message including event information regarding an event from a mobile device, upon an occurrence of the event; generating an action request message requesting execution of an application related to the event based on the event information and transmitting the action request message to the mobile device; and displaying a Graphical User Interface (GUI) to a user according to the execution of the application.
