Vehicle HMI Mapping for Non-OEM Mobile Control Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle head units may become outdated or non-functional over time, limiting users' options for replacement with non-OEM devices that lack access to vehicle networks and sensor data, thereby restricting functionality and interoperability with vehicle systems.
Innovation Solution
A method and system that enable a non-OEM handheld mobile device to couple with a vehicle network, allowing the presentation of OEM HMI on the mobile device, thereby providing functionality equivalent to the head unit, including access to vehicle controls and sensor data through HMI mapping and authentication processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a non-OEM handheld mobile device is used to replace the head unit, then device versatility and user flexibility are improved, but access to vehicle network and sensor data is lost
Solution Approach 1:
The patent introduces an intermediary system consisting of a vehicle network interface and communication protocols that enable the non-OEM mobile device to access vehicle network data. The mobile device couples with the vehicle network through authorized communication channels, allowing it to receive and process sensor data and vehicle information without being an original equipment manufacturer device.
2Adaptability or versatility
If OEM HMI functionality is presented on a non-OEM device, then interoperability with vehicle systems is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal HMI framework that can present OEM human-machine interface functionality on non-OEM devices. The system uses standardized communication protocols and data formats that allow the mobile device to perform multiple functions including displaying vehicle information, controlling vehicle systems, and accessing sensor data through a unified interface layer.
3Reliability
If authentication and HMI mapping processes are implemented, then security and data access control are improved, but operation time and setup complexity increase
Solution Approach 1:
The patent implements preliminary authentication and HMI mapping processes that are performed automatically when the non-OEM mobile device first couples with the vehicle network. The system pre-establishes communication channels, authenticates the device, and maps HMI functions before the user begins normal operation, thereby minimizing the time required for setup during actual use.

AI summary
An original equipment manufacturer (OEM) human-machine interface (HMI) device operation of a non-OEM handheld mobile device is provided. A non-OEM handheld mobile device can be coupled with a vehicle network of a vehicle. The vehicle can include a head unit with a display. An OEM HMI can be presented on a display of the non-OEM handheld mobile device. Thus, the non-OEM handheld mobile device provides functionality associated with the head unit and/or functionality not associated with the vehicle. Responsive to receiving an input on the OEM HMI presented on the non-OEM handheld mobile device, a setting or control of a vehicle device can be caused to be adjusted. Alternatively or in addition, responsive to receiving an input on a vehicle OEM HMI, a setting or control of the non-OEM handheld mobile device can be caused to be adjusted.
