Vehicle Voice Control Feedback Between Phone and Onboard Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face issues with inappropriate notification when voice recognition is performed differently between vehicle on-board devices and portable terminals, leading to uncomfortable user experiences due to inconsistent feedback.
Innovation Solution
A vehicle control system that includes both a vehicle on-board device and a portable terminal, equipped with voice recognition units, specification units, instruction units, and notification units, which prioritize wireless communication and authentication to ensure appropriate notification and control execution, even when voice recognition capabilities differ between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the portable terminal performs voice recognition independently, then the user can issue commands from outside the vehicle, but it causes inconsistent feedback when the vehicle on-board device also performs voice recognition
Solution Approach 1:
The notification unit provides feedback to the user about the operational state of the vehicle on-board device's voice recognition unit. When the voice recognition unit is operating, the system notifies the user that commands will be executed by the vehicle system, preventing confusion about which device is processing the command. This feedback mechanism ensures consistent user experience across different voice recognition scenarios.
2Ease of operation
If the portable terminal provides notification when voice recognition fails, then the user receives clear feedback, but it causes uncomfortable feelings when the vehicle on-board device is already performing voice recognition
Solution Approach 1:
Before the portable terminal's notification unit provides feedback, the system first checks the operational state of the vehicle on-board device's voice recognition unit. This preliminary check prevents the portable terminal from providing conflicting notifications when the vehicle system is already processing the voice command, thereby avoiding user discomfort while maintaining clear communication when appropriate.
3Adaptability or versatility
If both portable terminal and vehicle on-board device perform voice recognition, then more flexible command input is available, but it increases system complexity for managing recognition states
Solution Approach 1:
The notification unit acts as an intermediary between the portable terminal's voice recognition and the vehicle on-board device's voice recognition. It monitors and communicates the operational state of the vehicle's voice recognition unit, coordinating the interaction between the two systems. This intermediary function simplifies the management of dual voice recognition systems by providing a standardized interface for state information.

AI summary
A vehicle control system includes a portable terminal and a vehicle on-board device that carries out wireless communication with the portable terminal. The vehicle on-board device includes a first voice recognition unit that recognizes a voice and a control unit that executes control of a vehicle according to the voice recognized at the first voice recognition unit. The portable terminal includes a second voice recognition unit that recognizes a voice, a specification unit that specifies control of the vehicle according to the voice recognized at the second voice recognition unit, an instruction unit that instructs the control unit to execute the specified control of the vehicle, and a notification unit that, in a case in which the control of the vehicle according to the voice recognized at the second voice recognition unit cannot be specified at the specification unit, performs notification according to at least an operation state of the first voice recognition unit.
