Vehicle Cockpit Display Control by Passenger Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cockpit systems lack the ability to dynamically adjust display settings based on the presence of a passenger, leading to potential safety hazards and reduced convenience due to passengers arbitrarily operating the driver's screen.
Innovation Solution
A cockpit system with a front display, operating system, and camera that can detect the presence of a passenger, adjusting display settings and operating system configurations accordingly, including the ability to deactivate or activate specific displays and shy buttons based on passenger presence, and providing information through a see-through panel during a low mode to secure the driver's forward vision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the front display is moved downward in low mode to secure driver's forward vision, then the driver's forward vision is improved, but the display visibility and information provision capability deteriorate
Solution Approach 1:
The patent introduces a see-through panel as a new dimensional layer between the driver and the front display. This panel allows light to pass through from the lower area of the display, creating a see-through display effect that provides information to the driver without blocking forward vision. The solution moves from a two-dimensional display plane to a three-dimensional optical path solution.
Solution Approach 2:
The see-through panel acts as an intermediary element that mediates between the display and the driver's view. It transmits light from the display's lower area while maintaining the driver's forward vision, thus resolving the contradiction between information provision and vision security.
2Ease of operation
If the system allows passenger operation of the driver screen for convenience, then the ease of operation is improved, but the driving safety deteriorates due to potential distractions
Solution Approach 1:
The patent divides the display control rights into different local zones based on user position. The driver's seat area maintains full operation capability for safety-critical functions, while the passenger's seat area has restricted operation capability. This local differentiation allows passenger convenience for non-critical operations while preserving driving safety.
Solution Approach 2:
The camera system provides real-time feedback about user position and operation attempts. When the system detects a passenger attempting to operate the driver screen, it can provide feedback by blocking the operation or notifying the driver, thus preventing safety issues while allowing convenient operation when appropriate.
3Adaptability or versatility
If the system provides separate IVI displays for driver and passenger when passenger is present, then the adaptability and convenience are improved, but the device complexity increases
Solution Approach 1:
The system dynamically adjusts its configuration based on real-time detection of passenger presence. When a passenger is detected, the system activates separate IVI displays and control permissions; when no passenger is present, it consolidates to a single driver-focused configuration. This dynamic adaptation provides versatility without requiring permanently complex hardware.
Solution Approach 2:
The front display and controller serve multiple functions depending on the situation. The same hardware infrastructure supports both single-driver mode and dual-user mode, providing universal functionality that adapts to different occupancy scenarios without requiring separate dedicated systems for each mode.

AI summary
A cockpit system for vehicle and a method therefore are provided. The cockpit system includes: a front display disposed in front of a driver's seat and a passenger seat of the vehicle, the front display including one or more display areas; an operating system to receive an operation signal from a driver in the driver's seat or a passenger in the passenger seat; a camera to monitor presence, absence, or movement of the driver in the driver's seat or the passenger in the passenger seat; and a controller to control at least one display among the one or more displays of the front display, or control the operating system in conjunction with the camera.
