Vehicle Control System for Remote Autonomous Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote autonomous parking systems compute routes that are unnecessarily long by avoiding obstacles, including the user, which can lead to inefficient parking processes.
Innovation Solution
A vehicle control system that includes a terminal carried by the user, a control device, and external environment sensors to detect obstacles, allowing the system to compute and adjust routes based on the user's presence, ensuring safety and selecting a relatively short route by either having the user move out of the way or the vehicle traveling at a slower speed to avoid obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle computes the traveling route to avoid all obstacles including the user, then the safety is improved, but the traveling route becomes unnecessarily long and parking efficiency deteriorates
Solution Approach 1:
The system applies different obstacle avoidance rules to different spatial zones. The moving side area (where the user is expected to be present) is treated differently from other areas. Obstacles in the moving side area are not treated as avoidance targets when the user is present, while obstacles in other areas continue to be avoided, creating localized quality in obstacle handling
Solution Approach 2:
The system performs preliminary identification of the user's presence in the moving side area before computing the traveling route. By detecting whether the terminal is in the moving side area in advance, the system can pre-determine whether to apply the restricted or non-restricted route computation, avoiding unnecessary route lengthening
2Reliability
If the vehicle moves straight for a prescribed distance to detect obstacles, then the safety is improved, but the traveling time increases
Solution Approach 1:
The system applies obstacle detection selectively rather than continuously throughout the entire parking process. By moving straight for a prescribed distance only when necessary (when user is not in moving side area and obstacles may be present), the system performs partial detection action, avoiding excessive detection that would waste time while still ensuring safety when needed

AI summary
A vehicle control system includes a terminal, a control device, and an external environment sensor. The control device includes an action plan unit, an external environment recognizing unit, and a traveling control unit. The terminal includes a position detection unit and an input unit. In a case where a prescribed condition is satisfied, the action plan unit computes or maintains a traveling route that is not restricted by a person to be present in a moving side area located on one lateral side for which a vehicle should be headed. In a case where the prescribed condition is not satisfied, the action plan unit computes the traveling route such that the vehicle reaches a parking position after moving straight for a prescribed distance or more. The prescribed condition is satisfied in a case where a position of the terminal is present in the moving side area.
