Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance devices are not adaptable to different vehicle configurations, making them complicated to design and install, and users lack the ability to easily activate or deactivate functionalities, which can be annoying in certain situations.
Innovation Solution
A driving assistance device with a user interface system that generates activation and deactivation information, allowing users to switch between modes based on configuration information stored in non-volatile memory, using a selection module to control the operation of warning and trajectory correction modules, and a button actuation system for mode changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving assistance devices are designed specifically for a given vehicle configuration, then the device can be optimized for that specific configuration, but the design phase becomes complicated and installation and monitoring across different vehicle types become more complex
Solution Approach 1:
The driving assistance device is designed with a configuration reading module that can read different configuration information from various vehicle types, enabling the same device to adapt to multiple vehicle configurations rather than requiring separate devices for each configuration. This universal design approach resolves the contradiction by maintaining reliability through proper configuration adaptation while reducing design and installation complexity.
Solution Approach 2:
The device changes its operational parameters based on the configuration information it reads from the vehicle. By dynamically adjusting its behavior according to the detected vehicle configuration, the device can be optimized for each specific configuration without requiring separate hardware designs, thus maintaining reliability while simplifying the overall system complexity.
2Reliability
If driving assistance functionalities are always active, then safety and driving comfort are continuously improved, but the device becomes inconvenient in certain driving situations where users need to deactivate functionalities
Solution Approach 1:
The driving assistance device transitions from a static always-on state to a dynamic state that can be adjusted by users. The control module enables users to switch between active and deactivated states based on current driving situations, resolving the contradiction by maintaining continuous safety capability while providing operational flexibility when needed.
Solution Approach 2:
The device incorporates user feedback through control inputs that allow users to activate or deactivate functionalities based on their assessment of the current driving situation. This feedback mechanism enables the system to adapt to user needs while maintaining the capability for continuous safety improvement when desired.
3Adaptability or versatility
If the device adapts to different vehicle configurations through configuration information, then the device can be used across various vehicle types, but the system requires additional modules for reading and processing configuration data
Solution Approach 1:
The configuration reading module acts as an intermediary that bridges the gap between the driving assistance device and various vehicle configurations. By introducing this intermediate component that handles configuration data, the device achieves broad adaptability across vehicle types while isolating the core assistance functionality from configuration-specific complexities.

AI summary
A driving aid device (10) comprises a first driving aid module (14) and a second driving aid module (16). A selection module (12) is designed, when the first module (14) is activated and the second module (16) deactivated: -to deactivate the first module (14) on receipt of a deactivation information item (OFF_INT) or, when a configuration information item equals a first value (LDW_CONF), on receipt of an actuation information item (B_REL) in respect of a button (52); -to activate the second module (16) on receipt of an activation information item (LDW+LKA_INT) in respect of the second module (16) or, when the configuration information item equals a second value (LDW+LKA_CONF), on receipt of said actuation information item (B_REL).
