Solution Overview
Problem
Current vehicle systems lack seamless integration and control functionality between mobile devices and vehicle computing systems, particularly in enabling smartwatch applications to communicate and execute vehicle control functions wirelessly.
Innovation Solution
A vehicle computing system that uses Bluetooth Low Energy (BLE) technology to communicate with nomadic devices and smartwatches, allowing for the transmission of control functions and user interface configurations based on unique identifiers, enabling features like vehicle control through smartwatch inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication technology (BLE) is implemented to enable smartwatch-vehicle system communication, then device connectivity and control functionality are improved, but system complexity and integration requirements increase
Solution Approach 1:
The patent introduces a nomadic device as an intermediary component that bridges communication between the smartwatch and vehicle computing system. The nomadic device receives wireless signals from the smartwatch, processes control functions, and communicates with the vehicle system, thereby enabling smartwatch-vehicle integration without requiring direct complex pairing between the smartwatch and vehicle system.
2Ease of operation
If multiple control functions are transmitted from smartwatch to vehicle system, then user convenience and functionality are improved, but communication protocol complexity and data transmission requirements increase
Solution Approach 1:
The patent segments control functions into distinct, standardized control function identifiers that can be independently transmitted and processed. Each control function (e.g., door unlock, engine start) is represented as a separate discrete unit, allowing the system to handle multiple functions through simple sequential transmission rather than complex bundled protocols.
3Adaptability or versatility
If unique user identifiers are used for application launching, then user-specific customization and security are improved, but signal processing complexity and identification requirements increase
Solution Approach 1:
The patent uses a simplified copy of user identification information embedded in wireless signals rather than processing complex user authentication data. The nomadic device receives signals containing user identifier references, matches them against stored application mappings, and launches appropriate applications without requiring full user credential verification or complex biometric processing.
Data Source
AI summary
A smartwatch having at least one controller in communication with an user interface and a transceiver. The transceiver configured to communicate with a nomadic device. The at least one controller configured to, in response to a wireless signal having a unique user identifier received at the nomadic device, receive a control function from an application corresponding to the unique user identifier. The at least one controller may be further configured to configure the user interface based on the control function.
