Driver Position-Based Collision Avoidance System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges in vehicle collision avoidance, particularly when entering intersections with limited visibility, as they must move forward to assess oncoming traffic, risking collisions, and struggle with reverse parking due to blind spots and obstructed views.
Innovation Solution
A vehicle collision avoidance system equipped with cameras and sensors that adjust the driver's field of view and side mirrors based on their head position, providing a wide-angle view when necessary to enhance visibility during intersections and reverse maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the driver moves the vehicle forward to observe oncoming traffic, then the driver's line of sight clears the parked vehicle, but the front end of the vehicle is exposed to oncoming traffic creating collision risk
Solution Approach 1:
A camera system is introduced as an intermediary to capture images of the road ahead and display them on a screen inside the vehicle. This allows the driver to observe oncoming traffic without physically moving the vehicle forward, eliminating the need to expose the front end to potential collisions while maintaining full visibility of the intersection.
Solution Approach 2:
The system performs preliminary imaging of the road ahead before the driver needs to make a decision. By continuously capturing and displaying images of the intersection and oncoming traffic, the driver has advance information about the safety of proceeding, eliminating the need to move forward to gather this information.
2Loss of information
If the driver enters the intersection to assess traffic, then visibility of oncoming vehicles is improved, but the vehicle is positioned in the path of potential oncoming traffic
Solution Approach 1:
The camera system serves as an intermediary that brings the external view into the vehicle cabin. The camera is positioned to capture images from the front of the vehicle, providing the driver with the same visibility they would have by entering the intersection, while the vehicle remains stationary and safe in its original position.
3Loss of information
If the driver positions themselves closer to the front bumper, then visibility of the intersection is improved, but the driver's position becomes unsafe in case of rear collisions
Solution Approach 1:
The camera system acts as an intermediary that transfers the visual information from the front of the vehicle to the driver's position in the cabin. This eliminates the need for the driver to physically relocate closer to the front bumper, maintaining both optimal visibility and safe positioning within the cabin protected from rear collisions.
4Object-affected harmful factors
If a camera system is installed to provide visibility, then collision risk is reduced, but device complexity increases
Solution Approach 1:
The camera system is designed to serve multiple functions: it provides visibility of the road ahead for intersection assessment, captures images for display on the vehicle's existing infotainment screen, and can potentially be integrated with other driver assistance systems. This multi-functionality justifies the added complexity by delivering comprehensive safety benefits through a single integrated system.

AI summary
A vehicle collision avoidance system has a camera disposed on a vehicle and arranged to monitor at least one collision prone region adjacent to the vehicle; a sensor positioned within the vehicle and arranged to determine a driver's head position relative to a designated point in the vehicle; a display disposed in view of the driver and coupled to the camera; and a controller configured to control operation of the sensor, the camera and the display. The controller activates the display and the camera to display the at least one collision prone region adjacent to the vehicle when the sensor detects that the driver's head is beyond a threshold distance from the designated point.
