Rear View Camera Display During Heavy Braking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rear view mirrors in vehicles can be obstructed, and existing backup camera systems only display the area behind the vehicle when in reverse, limiting the driver's visibility during heavy braking situations, which may lead to inadequate reaction time in avoiding collisions with vehicles in front or behind.
Innovation Solution
A display system with a camera and electronic control unit (ECU) that automatically switches to show the rear view on a display screen when heavy braking is detected, using sensors to determine brake application strength and anti-lock brake activity, allowing the driver to view both the front and rear environments with minimal eye movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a rear view mirror is used to view areas behind the vehicle, then the driver can monitor the rear environment, but the mirror may be partially or fully obstructed by window pillars, passengers, luggage, headrests, or other objects
Solution Approach 1:
The patent introduces a camera system as an intermediary device to capture rear view images, which are then displayed on a screen within the driver's field of view. This mediator bypasses the physical obstruction problem of traditional mirrors by providing an electronic alternative that is not blocked by interior objects.
Solution Approach 2:
The camera creates a visual copy of the rear environment and displays it on a screen mounted on the dashboard or windshield. This copy allows the driver to see behind the vehicle without relying on the physical mirror, effectively eliminating obstruction issues.
2Adaptability or versatility
If a backup camera system is used to view areas behind the vehicle, then obstruction issues are resolved, but the system only displays the area behind the vehicle when in reverse, limiting the driver's visibility during heavy braking situations
Solution Approach 1:
The system dynamically adjusts its operation mode based on detected braking conditions. When heavy braking is detected through sensor input, the system automatically switches from a reverse-only display mode to a continuous rear view display mode, providing adaptability to different driving scenarios.
Solution Approach 2:
The system uses sensors to detect braking conditions and provides feedback to the control unit, which then adjusts the camera display accordingly. This feedback mechanism enables the system to respond automatically to heavy braking situations by activating the rear view display when needed.

AI summary
A display system for a vehicle comprises a display mounted within a passenger compartment of a vehicle and at least one camera mounted to the vehicle and facing at least partially in a rear direction. A sensor is connected to the display system for the vehicle. An ECU is controllably connected to the display and the at least one camera. The ECU provides an image from the at least one camera when a predetermined threshold of brake application is sensed or anti-lock brake activity is sensed.
