Smart Shoe Pedal Position Sensing for Driver Input Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vehicle systems are unable to correct driver errors, such as accidentally pressing the accelerator instead of the brake pedal, leading to potential accidents, especially in situations where the driver becomes flustered and reacts to obstacles on the road.
Innovation Solution
The implementation of a smart shoe device that communicates with the vehicle's sensors to predict the driver's actions and correct pedal inputs, either by switching the pedals or deactivating the incorrect pedal, using data from accelerometers, gyroscopes, and other sensors to ensure the vehicle takes the correct action, thereby preventing accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional vehicle systems are used, then the system complexity is low, but the system cannot detect or correct driver errors leading to accidents
Solution Approach 1:
The system divides the monitoring function into multiple independent sensor components (accelerometer, gyroscope, proximity sensors) distributed throughout the vehicle. Each sensor independently monitors specific aspects of driver behavior and vehicle operation, with results aggregated by the control unit to make comprehensive safety determinations.
Solution Approach 2:
The smart shoe device acts as an intermediary between the driver and the vehicle control system. It captures driver intent through sensors in the shoe and communicates this information to the vehicle's control unit, which then mediates between the driver's actions and the vehicle's response, correcting errors without direct driver awareness of the intervention.
2Measurement precision
If smart shoe device with multiple sensors is implemented, then driver error detection accuracy improves, but device complexity increases
Solution Approach 1:
The smart shoe device integrates multiple sensor types (accelerometer, gyroscope, proximity sensors) into a single wearable unit that serves multiple functions: detecting driver intent, monitoring foot position, and predicting upcoming actions. This multi-functional approach consolidates what would otherwise be separate systems into one integrated device.
Solution Approach 2:
The system continuously monitors sensor data from the smart shoe and vehicle sensors, compares actual driver actions with predicted actions, and provides real-time feedback by correcting pedal inputs when errors are detected. This closed-loop feedback system continuously refines its accuracy by learning from the driver's behavior patterns.
3Reliability
If pedal switching or deactivation is implemented, then correction of driver errors is achieved, but ease of operation is reduced
Solution Approach 1:
The control unit acts as an intermediary that transparently handles the complexity of pedal switching and deactivation. The driver simply operates pedals normally, while the system silently intervenes by switching or deactivating pedals when errors are detected, maintaining ease of operation while ensuring safety.
Solution Approach 2:
The system applies preliminary corrective action by switching or deactivating the incorrect pedal before the driver's erroneous action can cause harm. This preemptive correction prevents accidents by counteracting the driver's mistaken input before it affects vehicle operation.
