In-Vehicle Touch Panel Application Control for Safe Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle devices fail to effectively prevent driver distraction during vehicle operation, as they either allow prohibited applications to be used or do not restrict operations appropriately when the vehicle is in motion, and existing navigation systems do not address the switching of applications or display methods during driving.
Innovation Solution
A program and method that control an information terminal with a touch panel mounted in a vehicle, using a connection detecting unit to restrict undesirable operations and display switching based on user input, allowing intuitive application switching without diverting the driver's attention from the road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If application operations are restricted during vehicle operation to prevent driver distraction, then driving safety is improved, but ease of operation deteriorates
Solution Approach 1:
The system dynamically changes the operational state of applications based on vehicle operation detection. When vehicle operation is detected, the system switches to a restricted mode where only predetermined operations are permitted. When vehicle operation is not detected, the system returns to normal operation mode. This dynamic adaptation resolves the contradiction by making the system flexible rather than statically restrictive.
Solution Approach 2:
The system pre-defines which applications and operations are permitted during vehicle operation before the actual driving scenario occurs. By establishing this whitelist of permitted operations in advance, the system prepares a safe operational framework that can be quickly activated when vehicle operation is detected, avoiding the need for complex real-time decision-making that would complicate the interface.
2Reliability
If the display area is configured with directivity in a fan shape to reduce driver distraction, then driving safety is improved, but adaptability deteriorates
Solution Approach 1:
The display system dynamically adjusts its configuration based on the operational context. During vehicle operation, the display presents information in a driver-friendly format with simplified operations. When not in vehicle operation, the display can show full-featured interfaces with all functions accessible. This dynamic display adaptation maintains safety during driving while preserving full versatility when the vehicle is stationary.
3Reliability
If warnings are displayed to prohibit application usage during driving, then driving safety is improved, but ease of operation deteriorates
Solution Approach 1:
Instead of merely displaying warnings that require driver attention and potential overriding, the system proactively prevents prohibited operations from being executed in the first place. By implementing technical restrictions that block disallowed applications and operations at the system level, the warning becomes unnecessary - the harmful action is prevented before it can occur, eliminating the need for distracting warnings while maintaining safety.

AI summary
The purpose of the present invention is to control an information terminal, equipped with a touch panel and installed in a vehicle, in a manner in which it can be operated without affecting driving. A drive mode application causes an information terminal, controlling the running of an application through first control on the basis of a user operation received via a touch panel, to function as: a connection detection unit, which detects a connection to a vehicle; a function limiting unit, which controls the running of the application through second control, different from the first control, on the condition that the connection to the vehicle is detected; and a display switching unit, which, on the basis of a sliding operation in a first direction received via the touch panel while a first application is being displayed, displays the first application and a second application.
