Vehicle Surround View Display Control via Dynamic Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle infotainment systems do not effectively display a surround view when the vehicle is moving or when objects are not within a predetermined distance, limiting user experience during parking and navigation.
Innovation Solution
The system generates a surround view by stitching images from multiple cameras and displays it based on vehicle speed, driver inputs, and presence of parking markers or objects, adjusting display settings to show relevant views and split-screen information for better user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the surround view is displayed only when the vehicle is stationary or moving very slowly, then the system avoids unnecessary display activation during normal driving, but the user experience is limited during parking and low-speed navigation maneuvers
Solution Approach 1:
The system dynamically adjusts the surround view display activation based on real-time driving conditions. The display control module monitors vehicle speed, steering wheel angle, and brake pedal position to determine when to activate the surround view display. This dynamic activation allows the display to be shown during parking and low-speed maneuvers while remaining hidden during normal driving, resolving the contradiction between limited activation conditions and enhanced user experience during critical operations
2Reliability
If multiple cameras and processing modules are added to provide comprehensive surround view and object detection, then spatial awareness and safety are improved, but the device complexity increases
Solution Approach 1:
The parking module serves multiple functions using the same camera inputs: it detects parking markers, identifies objects, monitors vehicle speed and steering conditions, and controls display activation. This multi-functionality approach allows comprehensive parking assistance without adding separate dedicated systems for each function, thereby improving reliability while controlling device complexity
Solution Approach 2:
The system combines images from multiple cameras (front, rear, left, right) into a single synthesized surround view display. By merging the camera inputs and processing them through a unified control module, the system achieves comprehensive spatial awareness without requiring separate display systems for each camera, thus improving safety while managing complexity
3Loss of information
If the surround view display is activated during vehicle movement, then continuous monitoring is provided, but distracting information may appear when not needed during normal driving
Solution Approach 1:
The display control module dynamically determines when to activate or deactivate the surround view display based on real-time monitoring of vehicle speed, steering wheel angle, and brake pedal position. The display is activated during parking and low-speed maneuvers where continuous monitoring is valuable, and deactivated during normal driving to prevent driver distraction, thus resolving the contradiction between continuous monitoring capability and driver attention

AI summary
A display control system of a vehicle includes a surround view module configured to generate a surround view including a predetermined top view image of vehicle and one or more features located within a predetermined area around the vehicle. A parking module is configured to selectively generate a parking signal when, for at least a predetermined period, a vehicle speed is less than a predetermined speed and at least one of: (i) an accelerator pedal position is less than a predetermined position; (ii) a brake pedal position indicates a request for vehicle braking; and (iii) a magnitude of a steering wheel angle is greater than a predetermined steering wheel angle. A display control module is configured to, in response to the generation of the parking signal, display the surround view on a display within the vehicle.
