Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autonomous driving systems face usability issues when the activation conditions for level 3 autonomous driving are not satisfied, making it difficult for users to understand the cause and resulting in poor usability.
Innovation Solution
An autonomous driving control apparatus and method that uses level 2 autonomous driving functions to satisfy the activation conditions for level 3 by controlling vehicle speed and lane alignment, and includes a processor to determine and adjust these conditions, as well as an output device to inform the user of adjustments made.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system strictly requires activation conditions to be satisfied before enabling autonomous driving function, then system safety and reliability are improved, but user convenience and ease of operation deteriorate when conditions cannot be met
Solution Approach 1:
The system performs preliminary actions by automatically adjusting vehicle speed and lane alignment using level 2 autonomous driving functions before attempting to activate the level 3 autonomous driving function. This preliminary adjustment ensures that when the user requests level 3 activation, the system proactively creates the necessary conditions (satisfying activation criteria) rather than simply rejecting the request, thereby maintaining both reliability through condition verification and user convenience through automatic preparation.
2Loss of information
If the system provides detailed information about condition satisfaction status, then user understanding and information completeness are improved, but system complexity and information processing requirements increase
Solution Approach 1:
The system implements feedback by providing real-time information to the user about the satisfaction status of activation conditions through the output device. This feedback mechanism informs users whether conditions for level 3 autonomous driving are met or what adjustments are being made, ensuring information completeness without requiring complex additional subsystems, as the feedback leverages existing processing and communication infrastructure.
Solution Approach 2:
The system segments the activation conditions into distinct evaluable criteria (vehicle speed condition, in-lane alignment condition) and provides information about each separately. This segmentation allows the system to manage complexity by breaking down the overall activation process into manageable, independently assessable components, making it easier to track and communicate status without overwhelming system or user complexity.
3Productivity
If the system automatically adjusts vehicle state to satisfy activation conditions, then autonomous driving activation success rate is improved, but control system complexity and adjustment coordination requirements increase
Solution Approach 1:
The system applies universality by using the level 2 autonomous driving functions (smart cruise control for speed adjustment, lane following assist for alignment adjustment) to satisfy the activation conditions for level 3. Instead of designing separate dedicated adjustment mechanisms, the system leverages the existing multi-functional autonomous driving capabilities already present in the vehicle, thereby improving activation success rate without significantly increasing control system complexity.

AI summary
An autonomous driving control apparatus for a vehicle includes: a processor to determine activation of an autonomous driving function depending on whether a current driving situation satisfies an activation condition of the autonomous driving function during autonomous driving control; and a storage configured to store a set of instructions and data for determination and performance by the processor. In particular, the processor controls a vehicle to satisfy the activation condition and then determines activation of the autonomous driving function when the activation condition is not satisfied and a request to activate the autonomous driving function is inputted from a user.
