Autonomous Travel Control for Bicycle-Aware Shared Road Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems struggle to differentiate between bicycles and two-wheelers, leading to unnecessary transitions from autonomous to manual control when a two-wheeler is detected, thereby reducing usability.
Innovation Solution
A travel controller that uses a processor to detect two-wheelers, determine if the road is shared, and only notify the driver of a transition demand from autonomous to manual control when the road is shared and the two-wheeler is not a bicycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle control system transitions from autonomous to manual control when a two-wheeler is detected, then the safety is improved, but the usability deteriorates due to unnecessary transitions when two-wheelers other than bicycles are detected
Solution Approach 1:
The detection system segments two-wheelers into different categories (bicycles vs. other two-wheelers) based on specific distinguishing features. The processor analyzes detection data to identify whether the detected two-wheeler is a bicycle by examining characteristics such as vehicle size, speed, and structural features, thereby enabling differentiated control responses for different two-wheeler types
Solution Approach 2:
The system changes the detection parameters and criteria based on the type of two-wheeler detected. For bicycles, the system uses parameters such as smaller vehicle dimensions, lower speed ranges, and specific structural characteristics to trigger autonomous-to-manual control transitions, while for other two-wheelers, different parameter thresholds are applied to maintain autonomous control
2Reliability
If the vehicle control system transitions to manual control whenever a two-wheeler is detected, then the safety is improved, but the automation level deteriorates
Solution Approach 1:
The control system segments the response to two-wheelers into different automation levels based on the detected type. When a bicycle is detected, the system transitions to manual control (lower automation), while when other two-wheelers are detected, the system maintains autonomous control (higher automation), thereby preserving overall automation levels while ensuring safety where needed
Solution Approach 2:
The automation level dynamically adjusts based on the detected two-wheeler type. The processor continuously monitors detection data and dynamically changes the control mode between autonomous and manual operations, allowing the system to maintain high automation for most scenarios while switching to manual control only when necessary for safety
Data Source
AI summary
A travel controller of a vehicle that can travel on a road under autonomous driving control detecting two-wheelers, including bicycles, located in surroundings of the vehicle from surrounding data representing the surroundings of the vehicle generated by a surrounding sensor mounted on the vehicle, determining whether a target road on which the vehicle was traveling when the surrounding data in which a two-wheeler was detected was generated is a shared road on which travel by bicycles is permitted, when it is determined that the target road is a shared road, notifying a driver of the vehicle of a transition demand demanding transition in control of the vehicle from autonomous driving control to manual driving control requiring driving operations by the driver of the vehicle, and when it is determined that the target road is not a shared road, not notifying the driver of the transition demand.
