Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operating a smart device while driving poses a safety risk due to the need for manual screen interactions, and existing solutions like mirror projection result in poor user experience and safety issues.
Innovation Solution
A display control method that recognizes speech input to project a target application from a connected terminal to a vehicle's on-board computer in a preset display mode, allowing for full or partial screen projection and responding to user interactions without manual operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual screen interaction is used to operate terminal applications while driving, then application functionality is accessible, but driving safety deteriorates
Solution Approach 1:
The patent replaces manual mechanical screen interaction with voice-based acoustic control. The voice recognition module captures speech inputs from the driver and converts them into control commands, eliminating the need for physical contact with the terminal screen while maintaining application accessibility.
Solution Approach 2:
The patent introduces an on-board computer as an intermediary device between the driver and the terminal application. The on-board computer receives voice commands, processes them through the voice recognition module, and controls the terminal application accordingly, acting as a mediator that enables hands-free operation.
2Reliability
If terminal screen is projected to on-board computer screen, then driving safety is improved by reducing manual operations, but user experience deteriorates due to poor display adaptation
Solution Approach 1:
The patent dynamically changes display parameters including resolution, screen orientation, and interface layout to match the characteristics of the on-board computer screen. The system detects the target screen's properties and adjusts the terminal application's display output accordingly, ensuring optimal visual presentation without manual intervention.
Solution Approach 2:
The patent implements dynamic display adaptation where the system automatically adjusts display parameters in real-time based on the detected screen characteristics. This dynamic adjustment mechanism allows the interface to adapt flexibly to different on-board computer screens, maintaining high user experience quality.
3Reliability
If speech recognition is implemented for control, then hands-free operation is achieved improving safety, but system complexity increases
Solution Approach 1:
The patent makes the on-board computer serve multiple functions: it acts as both the control system for voice recognition and the display management system for adapting terminal applications. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in system complexity while maintaining hands-free operation capabilities.

AI summary
The invention relates to a display control method and apparatus, a vehicle, a terminal, and a storage medium. The vehicle recognizes (S101), in response to obtaining a speech input message, a control instruction corresponding to the speech input message. If the control instruction instructs the terminal to display a target application in a preset display mode to an on-board computer of the vehicle, a display parameter corresponding to the preset display mode is sent (S102) to the terminal. The terminal is connected to the vehicle via a network, the target application is installed on the terminal, and the target application is not installed on the on-board computer. Interface rendering data generated by the terminal according to the display parameter is received (S103), and an interface of the target application is displayed (S103) on a screen of the on-board computer in the preset display mode according to the interface rendering data.
