Rearview Mirror Visual Indicator for Reverse Parking Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges while reverse parking due to limited rearview visibility, as existing systems require them to look at a front display for video data from rear-facing cameras, which can be inconvenient and increase the risk of accidents.
Innovation Solution
A reverse parking assistance system that includes sensors to detect objects in the rear environment and provides a visual alert aligned with the detected object's location within the vehicle, allowing the driver to focus on the rear without needing to view a front display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video data from rear-facing camera is presented on a front display, then the driver can see the rear environment, but the driver must look toward the front of the vehicle which diverts attention from the rearview
Solution Approach 1:
The patent moves the visual information display from the front dimension (front display) to the rear dimension (rearview mirror integration), allowing drivers to access rear environment information without changing their viewing direction. This dimensional repositioning resolves the contradiction by making rear visibility accessible in the same spatial dimension where the driver naturally focuses attention during reverse parking.
2Loss of information
If a rear display is provided in the rearview mirror, then the driver can see rear environment information while looking rearward, but the device complexity increases
Solution Approach 1:
The patent merges the rearview mirror function with the rear environment display function into a single integrated unit. By combining these two previously separate functions, the system adds rear visibility capability without proportionally increasing overall device complexity, as the display is integrated into the existing mirror structure rather than being a separate component.
Solution Approach 2:
The rearview mirror is transformed into a multi-functional device that simultaneously provides traditional rearview reflection and digital display of rear camera footage. This universalization allows the same component to serve multiple purposes, reducing the need for additional dedicated devices and thereby limiting the increase in system complexity.
3Measurement precision
If visual alert is aligned with detected object location, then the driver can accurately locate objects in the rear environment, but the manufacturing precision requirements increase
Solution Approach 1:
The system employs feedback mechanisms where the position of detected objects in the camera field of view is automatically mapped to corresponding positions on the display within the rearview mirror. This software-based positional feedback eliminates the need for high manufacturing precision in physical alignment, as the alignment is dynamically calculated and adjusted through coordinate transformation algorithms.

AI summary
Arrangements relate to providing assistance during reverse parking of a vehicle. A rear environment of the vehicle can be detected for one or more objects located in the rear environment. If an object is detected in the rear environment, a visual alert of the detected object can be provided. The visual alert can be provided in a rear interior portion of the vehicle. The visual alert can be substantially aligned with the location of the detected object in the rear environment. Thus, a rearward-looking driver can be visually alerted of the presence of the detected object in the rear environment.
