Vehicle Brake Actuation Sensor for Driver Style Profiling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems lack the ability to effectively characterize and adapt to individual driver braking and driving styles, leading to suboptimal vehicle performance and maintenance predictions.
Innovation Solution
A sensor and control device that creates a personalized braking and driving profile by analyzing brake actuation data, allowing for precise adaptation of vehicle settings and predictive maintenance, while also enabling vehicle-to-vehicle communication and panic/theft recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a personalized braking and driving profile is created by analyzing brake actuation data, then driver comfort and vehicle operability are improved, but device complexity increases
Solution Approach 1:
The system segments the braking process into distinct measurable parameters (brake actuation force, brake actuation travel, brake actuation time) that can be independently analyzed to create the driver profile, making the complex task of characterizing driver behavior manageable through divided measurement components
Solution Approach 2:
The sensor and control device serves multiple functions: it monitors brake actuation parameters, creates driver profiles, predicts maintenance needs, and adapts vehicle settings, thereby improving ease of operation without requiring separate dedicated systems for each function
2Measurement precision
If brake actuation parameters are continuously monitored and analyzed, then measurement precision of driver behavior is improved, but use of energy increases
Solution Approach 1:
The system performs periodic sampling of brake actuation parameters during braking events rather than continuous monitoring, analyzing data at relevant moments (during brake application) while remaining dormant during normal driving, thus achieving precise driver behavior characterization with reduced energy consumption
3Adaptability or versatility
If driver-specific setpoint operating modes are established based on braking style information, then adaptability of the vehicle is improved, but device complexity increases
Solution Approach 1:
The system pre-establishes driver profiles by analyzing historical brake actuation data and pre-defines driver-specific setpoint operating modes based on these profiles, so that when a driver operates the vehicle, the appropriate adaptive settings are already prepared and can be quickly applied without complex real-time decision-making
