Adaptive Cockpit Display Height for Manual and Self-Driving Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional large-screen vehicle displays interfere with the driver's line of sight and safety due to excessive light emission, necessitating a solution that adapts the display to different driving states to minimize interference during manual driving while maximizing entertainment during autonomous driving.
Innovation Solution
A cockpit display screen control method that adjusts its display state based on the vehicle's driving mode, transitioning between a slender screen for manual driving to reduce interference and a wide or ultra-large screen for autonomous driving to enhance user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a general notification message is displayed on the navigation screen, then the driver can receive information, but the driver's attention is distracted from the road
Solution Approach 1:
The patent introduces a notification agent as an intermediary component that intercepts and processes notification messages before they reach the navigation display. This agent determines whether to block or forward notifications based on driving context, thereby mediating between the need for information delivery and the need to prevent driver distraction. The notification agent acts as a filter that selectively allows certain notifications through while blocking others, resolving the contradiction by introducing an intelligent intermediary layer.
Solution Approach 2:
The patent implements dynamic notification display behavior that adapts to the vehicle's driving state. When the vehicle is detected to be in motion, notification display is blocked or modified. When the vehicle is stationary or in parking mode, notifications are displayed normally. This dynamic adjustment of notification behavior based on real-time driving conditions resolves the contradiction by making the notification system flexible rather than static, allowing it to prioritize safety during driving while maintaining information delivery during non-driving states.
2Object-affected harmful factors
If notification messages are blocked during driving, then driver safety is improved, but the driver misses important information when parked
Solution Approach 1:
The notification agent dynamically adjusts its filtering behavior based on the vehicle's operational state. It transitions between blocking mode (when vehicle is moving) and passing mode (when vehicle is stationary), ensuring that notifications are blocked only when necessary for safety while allowing them through when the vehicle is parked or stationary. This dynamic state-dependent behavior resolves the contradiction by making the notification system adaptive to context rather than uniformly blocking or allowing all notifications.
Solution Approach 2:
The system implements feedback through the notification agent that continuously monitors vehicle state (moving vs. stationary) and adjusts notification behavior accordingly. The notification agent receives feedback about vehicle motion status and uses this feedback to determine whether to block or forward notifications. This closed-loop feedback mechanism ensures that notification delivery is optimized for each driving context, resolving the contradiction between safety and information delivery.
3Loss of information
If the navigation system processes all notification messages, then complete information is provided, but system complexity and processing load increase
Solution Approach 1:
The patent extracts the notification filtering function from the main navigation system by introducing a separate notification agent component. This agent is responsible for intercepting and processing notification messages independently, determining which notifications should be blocked and which should be forwarded to the navigation display. By extracting this filtering functionality into a separate modular component, the system reduces the processing burden on the main navigation system while maintaining complete information control, resolving the contradiction between information completeness and system complexity.

AI summary
Embodiments of this application provide a display method adaptive to a driving status of a vehicle and a related apparatus, and are applied to a vehicle with a self-driving function. When the vehicle is switched to a manual driving state, a cockpit display screen in the vehicle presents a first display state, and a screen height of the cockpit display screen in the first display state is a first height. When the vehicle is switched to a self-driving state, the cockpit display screen in the vehicle presents a second display state, and a screen height of the cockpit display screen in the second display state is a second height. The second height is greater than the first height. When the vehicle is in different driving states, the cockpit display screen may present different heights, so that an entertainment requirement and a safe driving requirement that are of a user both can be met.
