Movement Assistance Control for Road-to-Sidewalk Safety Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems face challenges in managing smooth vehicle movement across areas with different attributes, such as general roads and sidewalks, without disrupting the flow of travel, especially in regions without mandatory stopping rules, and fail to address safety checks when no pedestrians are detected.
Innovation Solution
A control device and method that acquires peripheral environment data to determine risk levels and provides movement assistance by prompting users to check for safety when transitioning between areas with different attributes, adjusting safety checks based on risk comparisons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle stops temporarily in front of a sidewalk every time passing over it, then safety is improved, but smooth flow of traveling is disrupted
Solution Approach 1:
The system applies different stopping behaviors to different areas: it stops temporarily when transitioning from a general road to a sidewalk area, but does not stop when transitioning between areas of the same type or from sidewalk to general road. This localized differentiation resolves the contradiction by making safety checks only where necessary rather than universally.
Solution Approach 2:
The stopping behavior is made dynamic based on real-time detection of area attributes and transition directions. The control device dynamically adjusts whether to stop or continue moving by evaluating the current and target area types, enabling flexible adaptation to different traffic conditions while maintaining safety where needed.
2Productivity
If the vehicle does not stop when passing over a sidewalk in regions without mandatory stopping rules, then smooth flow of traveling is maintained, but safety checks may be insufficient
Solution Approach 1:
The system implements location-specific safety protocols by detecting area attributes and applying appropriate stopping rules. In regions or situations where sidewalk transitions require safety checks, the vehicle stops; in other cases, it maintains smooth flow. This resolves the contradiction by making safety requirements local rather than universal.
Solution Approach 2:
The control device uses feedback from area attribute detection and transition direction analysis to dynamically determine whether safety checks are needed. This feedback mechanism ensures safety is maintained in critical situations while allowing smooth flow in less critical scenarios, resolving the contradiction between safety and efficiency.
3Reliability
If the vehicle stops temporarily in front of a pedestrian crossing when a pedestrian is detected, then safety is improved, but vehicle movement control on general roads or off roads without pedestrians is not addressed
Solution Approach 1:
The control device extends its functionality beyond pedestrian crossing detection to handle transitions between any areas with different attributes (general roads, sidewalks, off-road areas). This universal approach covers all movement scenarios regardless of pedestrian presence, resolving the contradiction by making the system versatile across different environments and conditions.
Solution Approach 2:
The system dynamically adapts its control behavior based on the types of areas being transitioned between and the direction of transition. It provides comprehensive coverage for general roads, off-road areas, and sidewalk transitions by evaluating area attributes in real-time, ensuring appropriate safety measures are applied across all scenarios rather than only for pedestrian crossings.

AI summary
A control device for a moving object, the control device includes: a data acquisition unit that acquires peripheral environment data of the moving object; and a movement assistance unit that determines a peripheral environment risk of the moving object based on the peripheral environment data and provides movement assistance for the moving object based on the peripheral environment risk. When the moving object moves across a first area and a second area with different attributes, the movement assistance unit provides predetermined movement assistance that prompts a user of the moving object to check for safety based on a comparison between a peripheral environment risk of the first area and a peripheral environment risk of the
