Vehicle Steering Warning Control for Hands-Free Lane Deviation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems generate excessive lane deviation warnings when the steering apparatus does not need to be gripped, causing driver unease due to unclear response requirements.
Innovation Solution
A vehicle control apparatus that differentiates between states where steering grip is needed and not needed, suppressing deviation warnings in the latter state to prevent unnecessary alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If deviation warning is output when vehicle approaches boundary of travel path, then lane deviation suppression is improved, but driver unease increases when steering grip is not needed
Solution Approach 1:
The warning output is dynamically adjusted based on the driving state. When the vehicle is in automatic driving mode where steering grip is not required, the deviation warning is suppressed. When the driver needs to grip the steering, the warning is output normally. This dynamic adaptation resolves the contradiction by making the warning system responsive to the actual driving context.
Solution Approach 2:
The system changes the warning output parameter based on the driving state parameter. By detecting whether the vehicle is in a state requiring steering grip or not, the system modifies the warning behavior accordingly - outputting warnings when grip is needed and suppressing them when automatic control is active, thus eliminating driver unease while maintaining lane deviation suppression effectiveness.
2Object-affected harmful factors
If deviation warning is suppressed in automatic driving state, then driver unease is reduced, but lane deviation detection capability is worsened
Solution Approach 1:
The warning system is segmented into different output modes based on driving state. The lane deviation detection function remains active in both states, but the warning output is segmented - fully active when driver needs to grip, suppressed when automatic control is active. This segmentation maintains detection capability while reducing harmful warnings.
Solution Approach 2:
The control state detection acts as an intermediary between the lane deviation detection and the warning output. It mediates whether the warning should be output or suppressed based on the current driving mode, ensuring that detection precision is maintained while inappropriate warnings are filtered out.

AI summary
A vehicle control apparatus for controlling a vehicle based on surrounding area information of the vehicle, comprising: a control unit capable of controlling the vehicle in a first state in which gripping of a steering apparatus by a driver of the vehicle is needed and a second state in which the gripping is not needed, based on the surrounding area information; and a warning output unit configured to output a deviation warning when the vehicle has approached a boundary of a travel path, wherein if the vehicle is in the second state, the control unit suppresses output of the deviation warning performed by the warning output unit compared to a case where the vehicle is in the first state.
