Side-View Mirror Adjustment for Vehicle Blind-Spot Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers are unable to see moving objects in the blind spots of their vehicle's side-view mirrors, leading to insecurity and potential accidents, especially when changing lanes or turning, due to limitations in existing detection systems.
Innovation Solution
A vehicle blind-spot reduction device that includes side-view mirrors, actuators, detectors, and circuitry to adjust the display position of the mirrors based on detected moving objects in the blind spots, ensuring the driver can see these objects by adjusting the mirror angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the side-view mirror displays a fixed optical image, then the mirror structure remains simple and stable, but the driver cannot see moving objects in blind spots
Solution Approach 1:
The side-view mirror transforms from a static display to a dynamic one by enabling automatic adjustment of the optical display position. The actuator moves the optical display in response to detected moving objects, allowing the mirror to adapt its viewing angle dynamically to eliminate blind spots and improve driver visibility.
Solution Approach 2:
The control unit acts as an intermediary between the object detector and the actuator. It receives information about moving objects from the detector, processes this data to determine appropriate mirror adjustment, and sends control signals to the actuator to adjust the optical display position accordingly.
2Reliability
If the mirror optical display is adjusted frequently to track moving objects, then blind spot coverage improves, but the mirror positioning stability decreases
Solution Approach 1:
The system implements feedback control where the control unit continuously monitors the positions of moving objects detected by the object detector and adjusts the optical display position accordingly. This feedback mechanism ensures the mirror maintains stable positioning while adapting to changing environmental conditions and object locations.
Solution Approach 2:
The actuator adjusts the optical display position in advance based on predicted object trajectories and detection data. By performing preliminary adjustments before objects fully enter blind spots, the system maintains both responsiveness and stability, preventing excessive frequent adjustments.
3Loss of information
If the optical display position is adjusted to show moving objects, then driver awareness of blind spots improves, but the normal viewing function may be compromised
Solution Approach 1:
The optical display position is adjusted periodically or intermittently based on the presence and movement of detected objects, rather than continuously. The control unit activates adjustment only when moving objects are detected in blind spot regions, maintaining normal viewing function during periods when no adjustment is needed while periodically updating the display to eliminate blind spots.
Solution Approach 2:
The mirror system applies different display positions for different viewing needs. The control unit determines appropriate optical display positions based on the specific location and characteristics of detected objects, adjusting only the necessary portions of the mirror field of view while maintaining normal viewing function in other areas.

AI summary
A vehicle blind-spot reduction device includes side-view mirrors on sides of a vehicle, an actuator configured to move an optical display of each of the side-view mirrors, a detector configured to detect a display position of the optical display, a surrounding environment information acquirer configured to acquire environment information on surrounding of the vehicle, a moving object detector configured to detect a moving object running beside the vehicle on the basis of the surrounding environment information, a blind spot setter configured to set a blind spot of each of the side-view mirrors on the basis of the display position of the optical display, and a display surface adjuster. Based on determining that the moving object has entered the blind spot, the display surface adjuster causes the actuator to operate to adjust the display position of the optical display.
