Automated Driving Blind Spot Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated driving systems often cause vehicles to remain in blind spots of adjacent vehicles for extended periods, which can increase the risk of accidents due to reduced visibility and awareness.
Innovation Solution
A method and system using sensors and an automated driving system to monitor the positions of side vehicles and adjust the host vehicle's position to minimize the time spent in blind spots, employing adaptive cruise control and lane change maneuvers as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated driving system maintains specific speed and spacing, then cruise control function is improved, but vehicle remains in blind spot for extended period
Solution Approach 1:
The system dynamically adjusts vehicle speed and/or lane position based on real-time blind spot detection. When a blind spot condition is detected, the automated driving system transitions from maintaining fixed speed/spacing to actively modifying these parameters to exit the blind spot, thereby resolving the contradiction between maintaining cruise control reliability and reducing blind spot exposure time
Solution Approach 2:
The system implements continuous feedback by monitoring blind spot conditions and using this information to adjust driving parameters. The blind spot detection system provides real-time feedback to the automated driving controller, which then modifies speed or lane position to eliminate the blind spot condition, balancing cruise control performance with safety
2Loss of time
If automated driving system adjusts position frequently, then blind spot exposure is reduced, but system complexity increases
Solution Approach 1:
The automated driving system performs multiple functions using existing components: it maintains cruise control while simultaneously detecting blind spots and executing avoidance maneuvers. This multi-functionality allows the system to reduce blind spot exposure without requiring entirely separate dedicated systems, thereby limiting the increase in overall complexity

AI summary
A method and system for controlling a position of a vehicle relative to other vehicles on a road is provided. The method includes controlling a position of a host vehicle travelling in a lane of a road using an automated driving system and monitoring positions of one or more side vehicles located on either side of the host vehicle and traveling in adjacent lanes. The method further includes detecting a condition in which the host vehicle is or will be positioned in a blind spot of a side vehicle disposed on in an adjacent lane and adjusting the position of the host vehicle in response to the condition using the automated driving system such that the amount of time the host vehicle is or will be positioned in the blind spot of the side vehicle is reduced.
