Vehicle Speed Control Offset Based on Driver Behavior Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speed control systems in vehicles, particularly those with traffic sign recognition, do not effectively assist drivers in utilizing the speed offset function, leading to inconsistent adherence to posted speed limits and potential traffic obstruction.
Innovation Solution
A method and system that proactively adjust the speed control system's configuration based on a detected driver behavior pattern, recognizing and responding to repeated adjustments of the target speed relative to posted speed limits, offering a speed offset proposal to align with the driver's intended behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the permitted highest speed is adopted as the target speed for the speed control system, then the vehicle adheres to speed limits, but the driver may become a traffic obstruction due to inconsistent speed adjustments
Solution Approach 1:
The system proactively proposes a speed offset configuration before the driver manually adjusts the target speed repeatedly. By detecting the behavior pattern of manual corrections and automatically proposing the appropriate speed offset, the system performs the speed adjustment action in advance, eliminating the need for repeated manual interventions and ensuring smooth traffic flow while maintaining speed limit adherence.
2Ease of operation
If the speed offset function is made available to drivers, then drivers can adjust target speed above permitted highest speed, but drivers may not be aware of or unable to find the setting
Solution Approach 1:
The system automatically detects the driver's speed adjustment behavior patterns and self-configures the appropriate speed offset without requiring the driver to manually search for or understand the speed offset function. The system serves itself by monitoring driver actions and autonomously proposing the optimal configuration, making the advanced function accessible without requiring driver knowledge of its existence or location in the settings menu.
Solution Approach 2:
The system continuously monitors the driver's manual speed corrections as feedback and uses this information to automatically propose the appropriate speed offset configuration. By closing the feedback loop between driver behavior detection and configuration proposal, the system adapts to driver preferences and provides the speed offset function contextually, eliminating the need for drivers to proactively seek out the setting.
3Reliability
If the speed control system automatically adopts permitted highest speed as target speed, then speed limit compliance is improved, but driver intent regarding speed preferences is not considered
Solution Approach 1:
The system dynamically adapts the target speed configuration based on detected driver behavior patterns. Instead of statically adhering to the permitted highest speed or requiring manual driver input, the system monitors driver corrections and automatically adjusts the speed offset configuration to match driver preferences, creating a dynamic system that evolves with driver intent while maintaining speed limit compliance.

AI summary
A method is disclosed for changing a configuration of a speed control system of a vehicle based on detection of a driver behavior pattern. The method may include activating the speed control system, which controls a vehicle speed to a target speed; receiving traffic sign data describing a maximum permitted speed; adopting the maximum permissible speed as the target speed; and detecting a target speed correction describing a change in the target speed. The method may further include detection of a driver behavioral pattern that describes a change in the target speed based on adopting the maximum permitted speed as the target speed; and issuing a proactive configuration change suggestion when the behavior pattern is detected repeatedly, where by accepting the proactive configuration change proposal, the target speed deviates from the maximum permitted speed by a speed offset when the maximum permitted speed is adopted as the target speed.
