Brake Pedal Heel Contact Sensor for Driver Control Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers often lose control of their vehicles during braking due to lifting their heel off the floor while pressing the brake pedal, leading to compromised control, maneuverability, and confidence, especially for new drivers, resulting in swerving, harsh braking, and anxiety.
Innovation Solution
A sensor system, including a pressure-sensitive switch or pad installed beneath the brake pedal or attached to the driver's shoe, provides a warning through audio, visual, or vibration signals when the heel is not in contact with the floor, helping drivers maintain proper braking technique.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor system is installed to detect heel contact with the floor, then driving control and confidence are improved, but device complexity increases
Solution Approach 1:
The sensor system is divided into separate functional components: pressure-sensitive sensors embedded in the floor mat, a controller unit, and warning indicators. This segmentation allows each component to perform its specific function independently, making the overall system more manageable and easier to install without requiring complete system replacement.
Solution Approach 2:
A floor mat with embedded pressure-sensitive sensors serves as an intermediary between the driver's heel and the vehicle floor. This intermediary component detects heel contact status and transmits information to the control system, enabling heel contact detection without modifying the vehicle's structural floor.
2Productivity
If warning indicators are added to provide feedback to the driver, then driving skill improvement is enhanced, but device complexity increases
Solution Approach 1:
Warning indicators (visual, auditory, or haptic) provide immediate feedback to the driver when heel contact is lost during braking. This feedback loop allows drivers to recognize and correct improper braking posture in real-time, accelerating skill development and reinforcing proper technique through repeated practice.
Solution Approach 2:
The system enables drivers to self-correct their braking posture through feedback without requiring external instruction or intervention. The warning indicators allow drivers to independently monitor and improve their own technique, making the training process autonomous and continuous.
3Measurement precision
If pressure-sensitive sensors are embedded in the floor mat, then heel contact detection accuracy is improved, but manufacturing complexity increases
Solution Approach 1:
The pressure-sensitive sensors are merged with the floor mat structure, combining the sensing function with the existing floor covering. This integration allows the sensors to be embedded within the mat layers during manufacturing, eliminating the need for separate sensor housing or complex installation procedures in the vehicle.

AI summary
An arrangement for training a vehicle driver or improving driving ability having a sensor located in a position beneath a motor vehicle brake pedal. A warning indicator is connected to the sensor to provide a signal when the sensor detects that a driver's heel is not in contact with a floor of the vehicle during braking.
