Vehicle Display Sub Processing Unit Booting Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle information display devices with single processing units experience prolonged booting times, leading to delayed availability of rear camera images during vehicle backup, potentially causing safety hazards and inconvenience to drivers.
Innovation Solution
Incorporating a sub processing unit that processes and displays images from a rear camera until the main processing unit completes its booting operation, utilizing a sensor to detect gear shift events and activate the camera unit, and controlling switching units to route image information and display data accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single processing unit is used to perform multiple complex functions, then device complexity is reduced, but booting time increases to 7 seconds or more
Solution Approach 1:
The processing unit is divided into a main processing unit and a sub processing unit. The sub processing unit specifically handles image processing from the rear camera, while the main processing unit handles other vehicle information display functions. This segmentation allows the sub processing unit to immediately process and display rear camera images when the vehicle enters backup mode, even before the main processing unit completes its booting sequence, thereby eliminating the need to wait for full system booting.
2Device complexity
If the main processing unit performs all image processing functions, then device complexity is reduced, but safety is compromised during booting when backup mode is activated
Solution Approach 1:
The sub processing unit is pre-configured and ready to immediately process and display rear camera images without waiting for the main processing unit to complete booting. When the vehicle enters backup mode, the sub processing unit activates beforehand to provide immediate visual feedback to the driver, ensuring safety is not compromised during the critical initial moments of system startup.
3Device complexity
If the system waits for the main processing unit to complete booting before displaying rear camera images, then processing resources are simplified, but driver convenience is reduced due to waiting time
Solution Approach 1:
The sub processing unit acts as an intermediary between the rear camera and the display unit during the booting period. It temporarily handles image processing and display output, bridging the gap between system startup and full functionality. Once the main processing unit completes booting, control transitions to the main unit, which then manages all processing functions centrally.

AI summary
Information display device and method for a vehicle are provided. The information display device for a vehicle includes: a camera unit that generates and outputs image information on the rear side of the vehicle; a main processing unit that performs predetermined functions including an image processing function on the image information; and a sub processing unit that processes the image information and displays the processed image information on a display unit until the main processing unit ends a booting operation, when the image information is output from the camera unit in a state where the main processing unit is performing the booting operation. Accordingly, it is possible to guarantee the safety at the time of backing a vehicle up even when the main processing unit is performing the booting operation and to make a driver not wait until the main processing unit ends the booting operation for the purpose of acquiring necessary information.
