Vehicle Remote Warning Override for Obstacle Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote operation warning systems for vehicles fail to reliably generate audible warnings when a movable portion, such as a window, is operated remotely, especially when the user has disabled the warning feature or set it to low volume, leading to potential contact with obstacles.
Innovation Solution
A function operation warning device that includes a receiving portion for remote control signals, a definition portion for determining audible warnings, an audible warning setting portion for user settings, and a warning generation portion that generates an audible warning at a predetermined volume, ensuring attention is drawn to potential obstacles even if warnings are disabled or set to low volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the user disables the warning feature or sets it to low volume through user settings, then the device complexity and user convenience are improved, but the reliability of obstacle warning is worsened
Solution Approach 1:
The system dynamically adjusts the warning behavior based on operational context. When remote operation is detected, the system automatically overrides user settings and enables audible warnings regardless of previous user preferences. This dynamic switching between respecting user settings and enforcing safety warnings resolves the contradiction by making the system adaptive to different operational states.
Solution Approach 2:
The system changes the warning parameter (audible warning enablement) based on the detection of remote operation. When a remote operation signal is received, the system modifies the warning state from disabled/low-volume to enabled/high-volume, effectively changing the safety parameter in response to a specific operational condition.
2Reliability
If the system always generates audible warnings during remote operation, then the obstacle warning reliability is improved, but the user convenience is worsened due to unavoidable warnings
Solution Approach 1:
The system implements dynamic warning behavior that activates only during remote operation modes. During local operation, the system respects user settings and may suppress warnings. This conditional activation resolves the contradiction by making warnings context-dependent rather than always active.
Solution Approach 2:
The warning system is segmented into different operational modes: remote operation mode and local operation mode. In remote mode, audible warnings are强制 activated for safety. In local mode, the system returns to normal user-configurable behavior. This segmentation allows the system to prioritize safety when needed while maintaining user convenience during normal operation.
3Reliability
If the system overrides user settings to generate warnings during remote operation, then the obstacle warning reliability is improved, but the device complexity increases
Solution Approach 1:
The system extracts the warning control logic from the general user setting system. A separate remote operation detection mechanism independently controls warning activation, separate from the main user preference management. This extraction resolves the contradiction by isolating the safety-critical warning function from the general user configuration system.
Solution Approach 2:
The system introduces an intermediary control layer that sits between user settings and the actual warning output. When remote operation is detected, this intermediary layer temporarily overrides user settings to ensure warnings are activated. This intermediary mechanism resolves the contradiction by providing a controlled interface between user preferences and safety requirements.

AI summary
A function operation warning device according to the invention includes a receiving portion that receives a control signal transmitted from an external remote transmitter; a definition portion that stores information that is used to determine whether an audible warning is generated in response to the control signal; an audible warning setting portion that stores settings concerning at least one of enable/disable of generation of the audible warning and a sound volume; a warning determination portion that determines, using the definition portion, whether the audible warning is generated, when the control signal is received; and a warning generation portion that generates the audible warning at a predetermined sound volume regardless of the settings stored in the audible warning setting portion, when the audible warning is generated as a result of determination made by the warning determination portion.
