Solution Overview

Problem

Existing systems fail to reliably convey information about a vehicle's automatic driving mode to users operating with mobile devices, especially when the user is distracted or not visually focused on the display, posing a risk in situations requiring immediate driver takeover.

Innovation Solution

A method and device utilizing a control unit and display unit to detect nearby mobile terminal devices, establish communication, and display system status information, including a frame-based interface with color-coded alerts and live environmental data, ensuring users are informed visually and acoustically of system state changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the driver uses a mobile terminal device, then communication functionality is improved, but visual perception of takeover requests is no longer guaranteed

Engineering Contradiction:
Improvecommunication functionalityVSAvoidvisual perception of takeover requests
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent extends the information display from the traditional in-vehicle display dimension to the mobile terminal dimension. By transmitting system status and takeover requests to the mobile device, the notification system operates in a new spatial dimension that the driver continuously monitors, thereby maintaining reliability of takeover request perception while preserving mobile device usage freedom.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The system establishes a feedback loop where the mobile terminal continuously receives and displays real-time system status information from the vehicle's control unit. This creates a continuous monitoring channel that provides immediate feedback to the driver about system state and takeover requests, ensuring the driver remains informed even when visually distracted by the mobile device interface.

Inventive Principle:
Principle #23Feedback

2Loss of information

If information is displayed only on the in-vehicle display unit, then system status is communicated, but the driver may miss critical information when focused on the mobile device

Engineering Contradiction:
Improvesystem status communicationVSAvoidinformation reception reliability
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

The patent creates a duplicate information display system where the mobile terminal receives and displays copies of critical system status information and takeover requests. This copying mechanism ensures that the same information is available in two locations (in-vehicle display and mobile terminal), guaranteeing that the driver cannot miss critical notifications regardless of where their visual attention is focused.

Inventive Principle:
Principle #26Copying
