Solution Overview

Problem

Current autonomous driving systems lack an intelligent and timely method for displaying driving states to users, making it difficult for them to perceive changes in driving states effectively.

Innovation Solution

A display method and system that uses stable-state and available-state icons on a vehicle's interface to indicate the current and switchable driving states, such as manual, adaptive-cruise-control, lane-center-control, and navigate-on-autopilot modes, enhancing user perception through dynamic and static information presentation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the driving state is displayed using a vehicle-mounted dashboard, then the driving state information is provided to the user, but the intelligence degree is low and users cannot perceive changes in the driving state in a timely manner

Engineering Contradiction:
Improvedriving state informationVSAvoidperception time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent segments the driving state information into multiple distinct visual elements including stable-state icons, available-state icons, and dynamic icons. Each icon type represents a specific aspect of the driving state (current state, switchable states, state changes), allowing users to quickly perceive different information categories without processing a single complex display element.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs different colors and visual styles for different icon types and states. Stable-state icons use one visual style, available-state icons use another, and dynamic icons use a third style. This color and visual differentiation enables users to immediately distinguish between different driving state information without reading text, significantly reducing perception time.

Inventive Principle:
Principle #32Color changes

2Loss of information

If multiple driving states are displayed simultaneously, then comprehensive driving state information is provided, but the interface complexity increases

Engineering Contradiction:
Improvedriving state informationVSAvoidinterface complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The interface is segmented into distinct functional zones: a first area for stable-state icons showing the current driving state, a second area for available-state icons showing switchable states, and a third area for dynamic icons showing state changes. This spatial segmentation organizes multiple pieces of information in a structured layout that reduces perceived complexity while maintaining comprehensiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic icons that animate to indicate state changes, while stable-state and available-state icons remain static. This dynamic element draws attention to important changes without requiring the entire interface to be complex or animated, maintaining simplicity while effectively communicating state transitions.

Inventive Principle:
Principle #15Dynamics

AI summary

A display method for a driving state is performed by a computer device and includes: displaying a first stable-state icon on a driving interface of a vehicle, the first stable-state icon being configured for prompting that the vehicle is in a first driving state; displaying a first available-state icon on the driving interface when a driving-state switching condition is satisfied, the first available-state icon being configured for prompting that the vehicle is able to activate a second driving state; and displaying a second stable-state icon on the driving interface in response to the vehicle being switched to the second driving state, the second stable-state icon being configured for prompting that the vehicle is in the second driving state.
