Electronic Side Mirror Overhead View for Low Obstacle Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driving assistance systems struggle to effectively detect low obstacles and ditches, leading to increased risk of collisions and wheel going off the road, particularly for novice drivers and those unfamiliar with the vehicle.
Innovation Solution
A driving assistance system that includes a first display device in front of the driver seat and an electronic side mirror, utilizing a determiner to generate an overhead image of the vehicle's surroundings, displaying this image on both the side mirror and display device, with the ability to adjust the display position based on the vehicle's turning direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional monitoring techniques are used to detect obstacles around the vehicle, then the system structure remains simple, but the detection capability for low obstacles and ditches is insufficient
Solution Approach 1:
The patent introduces an overhead view dimension to the traditional side-view monitoring system. By generating and displaying an overhead image showing the vehicle's position relative to obstacles and ditches, the system provides detection capability in a new dimensional perspective, enabling detection of low obstacles and ditches that are invisible in conventional side views.
Solution Approach 2:
The patent uses an electronic side mirror as an intermediary device to display the overhead image. This intermediary approach allows the overhead view to be integrated into the existing side mirror structure, providing enhanced detection capability without requiring a completely separate display system, thus balancing detection improvement with system complexity.
2Loss of information
If the driver focuses attention on the front of the vehicle, then forward driving performance is maintained, but awareness of side conditions and obstacles is reduced
Solution Approach 1:
The patent merges the overhead view information with the side mirror display, combining forward viewing and side condition monitoring into a single visual interface. This allows the driver to maintain attention on the front while simultaneously perceiving side conditions through the integrated overhead image displayed in the side mirror.
Solution Approach 2:
By presenting side condition information in an overhead dimensional perspective within the side mirror, the system enables the driver to perceive side obstacles and ditches without shifting attention from the front view, effectively adding a new informational dimension to the driver's field of view.
3Loss of information
If the overhead image is displayed on multiple devices simultaneously, then information availability is improved, but the device complexity and cost increase
Solution Approach 1:
The electronic side mirror serves multiple functions: it displays both the traditional side view and the overhead image simultaneously. This multi-functionality approach provides comprehensive information availability without requiring completely separate display systems, as the side mirror becomes a universal display device for both side monitoring and overhead visualization.
Solution Approach 2:
The patent combines the overhead image display with the existing side mirror functionality, merging two information streams into a single display device. This approach improves information availability by making overhead data accessible while avoiding the complexity of adding entirely separate display systems for different viewing angles.

AI summary
A driving assistance system provides driving assistance to a driver in a vehicle which includes a display disposed in front of a driver seat and an electronic side mirror, and includes: a display condition determiner that determines whether a predetermined condition is satisfied in the vehicle driven by the driver; an image processor that generates an overhead image including an area around the vehicle when the predetermined condition is satisfied; a first control device that displays, on the electronic side mirror, a first image including the overhead image generated by the image processor; and a second control device that displays, on the display, a second image including the overhead image generated by the image processor.
