Turning Collision Control Using Potential Collision Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle safety devices are prone to unnecessary activation during right or left turns due to reduced relative time-to-collision when oncoming vehicles turn or slip past, leading to false alarms.
Innovation Solution
A vehicle control device sets potential collision areas based on own vehicle and moving object speeds, determining the position of the object relative to the vehicle, and restricts safety device activation when the object is outside these areas, using cameras and radar to track and calculate positions and speeds.

If the safety device activates based on reduced relative time-to-collision, then response time is improved, but unnecessary activation occurs during normal turning maneuvers
Solution Approach 1:
The patent implements preliminary action by pre-defining potential collision areas before the turning maneuver completes. The control device determines in advance which spatial zones constitute collision risks during turns, and only activates the safety device when objects enter these predetermined zones. This approach maintains fast response times for genuine threats while preventing unnecessary activation during normal turning operations, as the system is already prepared with predefined criteria.

AI summary
A vehicle control device is provided for activating a safety device to inhibit occurrence of a collision with a moving object around an own vehicle, when the own vehicle transitions from traveling straight in a lane in which the vehicle is traveling to making a turn. An area setting unit is configured to, based on at least one of an own vehicle speed and a moving object speed, set a potential collision area, provided that the moving object continues to move in its moving direction and the own vehicle is making a right/left turn. An acquisition unit is configured to acquire a position of the moving object relative to the own vehicle. A restriction unit is configured to restrict activation of the safety device against the moving object based on the position of the moving object being out of the potential collision area.
