Adaptive Cruise Control Override Intent Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adaptive cruise control systems lack the ability to effectively interpret and utilize the intent of the vehicle operator during overrides, leading to potential inefficiencies and safety concerns.
Innovation Solution
A system comprising a processor and memory that includes an override ascertainment module, an intent ascertainment module, and an intent utilization module, which determines when an operator's action constitutes an override of the adaptive cruise control system, identifies the operator's intent to change settings, and utilizes this information to adjust the system's operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adaptive cruise control system automatically maintains speed and distance without interpreting operator intent, then the system operation is simple and automated, but the system cannot respond intuitively to operator preferences during overrides
Solution Approach 1:
The system performs preliminary actions by detecting and analyzing operator override inputs before the operator can explicitly adjust settings. The override ascertainment module proactively identifies when an operator is attempting to manually control the vehicle, and the intent ascertainment module anticipates the desired setting changes based on this detection, allowing the system to prepare responsive actions in advance
Solution Approach 2:
The system implements feedback by continuously monitoring operator actions during overrides and using this information to adjust ACC settings. The intent utilization module receives feedback from detected override behaviors and uses this feedback to automatically modify cruise control parameters, creating a closed-loop system that adapts to operator preferences in real-time
2Reliability
If the system ignores operator actions during overrides and maintains original settings, then the automated control is stable and consistent, but safety and efficiency are reduced due to inability to adapt to operator intent
Solution Approach 1:
The ACC system performs self-service by automatically detecting operator intent during overrides and adjusting its own settings without requiring explicit operator input. The system monitors its own operational state, identifies when an override is occurring, and autonomously modifies cruise control parameters based on the detected intent, enabling the system to serve itself in adapting to operator preferences
Solution Approach 2:
The system applies dynamics by making the ACC settings adjustable and adaptable rather than fixed. The intent utilization module dynamically modifies cruise control parameters based on real-time detection of operator behavior during overrides, allowing the system to transition between different operational states and adapt its control characteristics to match operator intentions
3Productivity
If the system requires explicit operator input for every setting change during overrides, then the system maintains precise control accuracy, but the operation becomes cumbersome and less efficient
Solution Approach 1:
The system applies partial action by implementing intermediate levels of automation between fully manual and fully automatic control. During overrides, the system automatically adjusts ACC settings to a degree that captures operator intent without requiring complete manual intervention, performing partial adjustments that balance automation efficiency with operational precision

AI summary
A system for controlling an adaptive cruise control system can include a processor and a memory. The memory can store an override ascertainment module, an intent ascertainment module, and an intent utilization module. The override ascertainment module can include instructions that cause the processor to determine, during an operation of the adaptive cruise control system, that an action, performed by an operator of an ego vehicle, is an override of the adaptive cruise control system. The intent ascertainment module can include instructions that cause the processor to determine, during the override, an intent of the operator to change a setting of a mechanism, of the adaptive cruise control system, to control a motion-related aspect of the ego vehicle, from a current setting to a preferred setting. The intent utilization module can include instructions that cause the processor to cause the adaptive cruise control system to utilize information about the intent.
