Vehicle Terminal Operation Control Based on Position and Driving State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver monitoring systems are prone to inaccuracies due to environmental factors, making it difficult to determine if a driver intends to operate a terminal apparatus, which can lead to unsafe operations.
Innovation Solution
A control apparatus that determines the presence of a terminal apparatus within a vehicle using positional data and assesses the driving state to decide whether to prohibit operations on the terminal apparatus, employing a server-based control system to communicate with both the vehicle and terminal devices, and utilizing in-vehicle displays to facilitate alternative operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image analysis is used to monitor driver state, then driver monitoring capability is provided, but determination accuracy deteriorates due to environmental factors
Solution Approach 1:
The patent introduces an intermediary approach by using terminal apparatus detection as an indirect indicator of driver intent. Instead of directly analyzing driver state through image processing, the system detects the presence of terminal devices (phones, tablets) in the driver's possession and infers potential distraction risk from this intermediate data, avoiding the accuracy problems of direct image analysis
Solution Approach 2:
The patent replaces the mechanical/optical image analysis system with an electronic data processing system. By substituting camera-based visual monitoring with terminal apparatus detection using electronic sensors and data communication, the system achieves more reliable and accurate determination of driver state without environmental interference
2Ease of operation
If driver operation on terminal apparatus is allowed, then driver convenience is improved, but safety deteriorates due to potential distraction
Solution Approach 1:
The patent implements a dynamic control system that adjusts terminal apparatus operability based on real-time driving conditions. The system dynamically switches between allowing and prohibiting terminal operations depending on whether the driving state is determined to be safe or unsafe, providing conditional convenience while maintaining safety
Solution Approach 2:
The system establishes a feedback loop where terminal apparatus detection results and driving state analysis continuously inform control decisions. The control apparatus receives feedback about terminal presence and driver state, then adjusts terminal operability permissions accordingly, creating a closed-loop safety mechanism that balances convenience and safety

AI summary
A control apparatus includes a controller configured to: determine whether a terminal apparatus is present in a vehicle with reference to first positional data that indicates a position of the vehicle and second positional data that indicates a position of the terminal apparatus; and in a case in which the terminal apparatus is determined as being present in the vehicle, determine, according to a driving state of the vehicle, whether to prohibit a first operation to be performed on the terminal apparatus.
