Vehicle Control Device for Portable Terminal Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems do not effectively allow drivers to execute pending operations on portable terminal devices during vehicle rides, as they lack the ability to actively notify drivers of available time for operations, leading to inefficient use of spare time and potential safety concerns during travel.
Innovation Solution
A vehicle control device that includes a carry-in state determination device, a pending process determination device, and a pending process control device, which enable the execution of pending processes on portable terminal devices when carried into a vehicle, ensuring safe operation by assessing the driver's ability and the vehicle's state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a driver operates a portable terminal device during driving, then the driver can execute pending operations and utilize spare time, but the driving safety is compromised
Solution Approach 1:
The system dynamically adjusts the operational state of the portable terminal device based on the vehicle's travel state. When the vehicle is moving, the system prohibits certain operations to ensure safety. When the vehicle is stopped or parked, the system enables pending operations. This dynamic control resolves the contradiction by making the system adaptable to different driving conditions rather than maintaining a fixed restrictive or permissive state.
Solution Approach 2:
The system allows the driver to set pending operations in advance before driving. These pending operations are queued and automatically executed when the vehicle is in a safe state (stopped or parked). This preliminary action enables the driver to prepare operations ahead of time without actually executing them during unsafe periods, thus maintaining both safety and productivity.
2Reliability
If the system prohibits operations during driving, then driving safety is maintained, but the driver cannot utilize spare time for pending operations
Solution Approach 1:
The system continuously monitors the vehicle's travel state and provides feedback to control the operational permission of the portable terminal device. When the vehicle stops or parks, the system detects this state change and automatically enables pending operations. This feedback mechanism ensures that operations are only permitted when safety conditions are met, while still capturing and utilizing all available spare time opportunities.
Solution Approach 2:
The system automatically manages the execution of pending operations without requiring continuous driver intervention. Once pending operations are set, the system autonomously determines the appropriate timing based on vehicle state and executes them independently. This self-service approach maximizes spare time utilization while maintaining safety, as the system handles the timing decisions without requiring the driver to actively manage both driving and operations.
3Productivity
If the system enables operations during travel, then spare time is utilized efficiently, but the driver's ability to safely operate the vehicle is compromised
Solution Approach 1:
The system segments the operational permission into different phases: setting pending operations can be done during driving, but actual execution is segmented to occur only during safe periods (stopped or parked). This segmentation allows the driver to maintain full vehicle control during operation while still achieving efficient execution of pending tasks during appropriate time windows.

AI summary
A vehicle control device includes: a carry-in state determination device that determines whether a portable terminal device to be carried into a vehicle is already carried into the vehicle; a pending process determination device that, when the carry-in state determination device determines that the portable terminal device is already carried into the vehicle, determines whether the portable terminal device has a pending process that is held in an unexecuted state; and a pending process control device that, when the pending process determination device determines that the portable terminal device has the pending process, enables the pending process to be executed by the portable terminal device in the vehicle.
