Automated Driving State Indication for Safer Road Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of automated driving vehicles on public roads poses challenges due to the gap in environment cognition, decision-making, and response capabilities between automated vehicles and human drivers, necessitating effective communication of automated driving status to surrounding traffic participants.
Innovation Solution
A method and apparatus for indicating and sending automated driving information, where a first vehicle indicates its automated driving state using specific indication information, which can include light signals, sound signals, or messages, to inform surrounding traffic participants of its driving status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated driving vehicles operate on public roads without indication information, then automation level is improved, but traffic safety deteriorates due to inability of surrounding participants to identify automated vehicles
Solution Approach 1:
The patent applies preliminary action by equipping automated vehicles with indication information (lights, sounds, or messages) that are activated before or during automated driving operations. This allows surrounding traffic participants to identify automated vehicles in advance, understand their driving status, and take appropriate preventive actions, thereby resolving the safety concern while maintaining automation benefits
Solution Approach 2:
The patent uses indication information as an intermediary communication medium between automated vehicles and surrounding traffic participants. This intermediary conveys the automated driving status to humans who cannot directly perceive the vehicle's operational mode, bridging the information gap and enabling safe interaction between automated and manual driving systems
2Reliability
If automated driving vehicles send detailed indication information to surrounding participants, then traffic safety is improved, but device complexity increases due to additional communication systems
Solution Approach 1:
The patent applies universality by designing indication information that can be transmitted through multiple channels (lights, sounds, or messages) using existing vehicle systems. This multi-functional approach allows a single communication framework to serve various transmission methods, reducing overall system complexity while maintaining comprehensive safety communication
Solution Approach 2:
The patent applies parameter changes by allowing the indication information to vary in format, intensity, and transmission method based on driving conditions, vehicle type, and environmental factors. This dynamic adjustment optimizes communication effectiveness without requiring complex dedicated systems for each scenario, as existing systems can be modulated to provide appropriate indication levels
Data Source
AI summary
A method for indicating, obtaining, and sending automated driving information includes: starting, by a first vehicle, an automated driving function application, or receiving, by a first vehicle, an instruction used to instruct the first vehicle to start an automated driving function application; and indicating, by the first vehicle by using first indication information, that a driving status of the first vehicle is an automated driving state. A vehicle having an automated driving function sends the automated driving information to a surrounding traffic participant, especially to a surrounding vehicle or a pedestrian, so that the surrounding traffic participant identifies the automated driving vehicle, to improve traffic safety of an entire road.
