Driving Assistance Hold Logic for Object-Aware Auto Start
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance devices struggle to prevent collisions between vehicles and objects when a vehicle automatically starts following a preceding vehicle, especially due to changes in the vehicle's environment such as pedestrian crossings.
Innovation Solution
A driving assistance device equipped with a determination unit that assesses whether an object is within a specified area in front of the vehicle when the preceding vehicle starts, and a driving assistance unit that maintains the vehicle's stopped state if an object is detected within that area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the vehicle automatically starts following the preceding vehicle, then the productivity of the vehicle is improved, but the reliability of collision avoidance deteriorates
Solution Approach 1:
The determination unit performs preliminary detection of objects in the specified area before the vehicle starts moving. This advance checking prevents collision by identifying pedestrians, vehicles, or other obstacles in the path ahead before the automatic starting sequence initiates, thereby resolving the contradiction between efficient automatic starting and collision avoidance reliability
Solution Approach 2:
The system continuously monitors the specified area in front of the vehicle during the automatic starting process. If an object is detected within the specified area, the driving assistance unit provides feedback to maintain the stopped state, preventing collision while allowing normal automatic starting when the path is clear
2Reliability
If the vehicle maintains stopped state when object is detected, then the reliability of collision avoidance is improved, but the productivity of vehicle starting is worsened
Solution Approach 1:
The system dynamically adjusts the starting behavior based on real-time detection results. When the specified area is clear, the vehicle starts automatically maintaining high productivity. When an object is detected, the system dynamically maintains the stopped state to ensure safety, thus adapting the productivity level to the actual environmental conditions

AI summary
A driving assistance device includes a determination unit configured to, in a case where a preceding vehicle located in front of a vehicle in a stopped state starts, determine whether an object is located inside a specified area that is a predetermined area in front of the vehicle, and a driving assistance unit configured to maintain the stopped state of the vehicle in a case where an object is located inside the specified area in a case where the preceding vehicle starts.
