Pedal Touch Feedback for Consistent Brake Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems fail to provide real-time feedback on brake pedal touching habits, which can vary significantly based on footwear and clothing, leading to inconsistent control inputs and potential safety risks.
Innovation Solution
A pedal touch anomaly notification system that establishes baseline pedal touching characteristics, detects deviations, and provides feedback in the form of tactile, auditory, visual, or textual alerts to drivers, using sensors to monitor foot position, orientation, and vehicle conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver wears different footwear or clothing, then the driver's comfort and personal preference are satisfied, but the pedal control precision and consistency deteriorate
Solution Approach 1:
The system continuously monitors pedal interaction characteristics through sensors and provides real-time feedback to the driver when anomalies are detected. This feedback loop allows the driver to adjust their pedal touching habits to maintain safe control precision while still permitting freedom of footwear choice.
Solution Approach 2:
The patent replaces direct mechanical measurement of pedal force with sensor-based detection systems that monitor pedal position, acceleration, and interaction characteristics. This substitution enables more precise and consistent measurement of pedal control regardless of footwear variations.
2Reliability
If the system provides real-time monitoring and feedback on pedal touching habits, then driving safety is improved, but the device complexity increases
Solution Approach 1:
The system uses existing vehicle sensors (accelerometers, position sensors) for multiple purposes - both for normal vehicle operation and for monitoring pedal touching habits. This multi-functionality approach reduces the need for additional dedicated sensors and reduces overall system complexity.
Solution Approach 2:
The system automatically establishes baseline pedal interaction characteristics for each driver and performs self-calibration without requiring manual setup. The anomaly detection and feedback mechanisms operate autonomously, reducing the complexity of user configuration and system maintenance.
3Measurement precision
If the system establishes individual baseline pedal touching characteristics for each driver, then the measurement precision of anomaly detection is improved, but the loss of time for baseline establishment occurs
Solution Approach 1:
The system performs preliminary baseline establishment during the initial driving sessions automatically, capturing the driver's natural pedal interaction patterns without requiring separate calibration appointments. This preliminary action occurs in the background during normal driving, minimizing time loss.
Solution Approach 2:
The baseline establishment is an ongoing continuous process that updates and refines the driver's pedal characteristics over time rather than a one-time static calibration. This continuous adaptation maintains high detection precision while distributing the time requirement across multiple driving sessions.
Data Source
AI summary
A pedal touch anomaly notification system for a vehicle is provided. The system includes the vehicle itself, and at least one sensor configured to capture information about the position or orientation of the driver's foot relative to a control pedal of the vehicle. A processor uses the captured information, as well as a database containing baseline information and variance information about expected positions or orientations of the driver's foot relative to the control pedal. Based on the captured information, the processor determines the position or orientation of the foot of the driver relative to the control pedal, and compares the determined position or orientation to the baseline information and variance information. If the position or orientation fall outside the variance information, the processor generates a driver alert.
