Traction Control Module Dynamic Disable for Vehicle Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traction and stability control systems in vehicles often inhibit tire spinning, which can hinder a vehicle's ability to get unstuck from challenging conditions like snow, without providing drivers with clear options to disable this feature effectively.
Innovation Solution
A traction control system that includes wheel speed sensors and a traction control module, which determines if a vehicle is stuck and allows drivers to disable the traction control system, either manually or automatically, to enable tire spinning for extraction purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the traction control system limits torque to prevent wheel spinning, then wheel stability is improved, but the vehicle's ability to get unstuck deteriorates
Solution Approach 1:
The system dynamically adjusts the traction control system's operation based on detected vehicle conditions. When the vehicle is detected to be stuck (through sensor data analysis of wheel speeds, transmission gear position, and vehicle speed), the system automatically disables traction control to allow wheel spinning for extraction. When not stuck, traction control remains active for stability. This dynamic adaptation resolves the contradiction by making the system's behavior context-dependent rather than fixed.
2Ease of operation
If the traction control system automatically disables when vehicle is stuck, then ease of operation is improved, but system complexity increases
Solution Approach 1:
The system performs self-service by automatically detecting when the vehicle is stuck and disabling traction control without requiring driver intervention. The traction control module monitors sensor data (wheel speed sensors, transmission control module data) and autonomously determines when to disable the system. This eliminates the need for driver knowledge of system operations while managing complexity through automated decision-making based on predefined criteria.
Solution Approach 2:
The system uses feedback from multiple sensors (wheel speed sensors, transmission control module) to continuously monitor vehicle conditions. This feedback loop enables the system to detect stuck conditions and automatically adjust traction control operation. The feedback mechanism manages complexity by using existing sensor data rather than adding new sensors, leveraging available information to drive automated decisions.

AI summary
Method and apparatus are disclosed for a traction and stability control system. An example vehicle includes wheel speed sensors on wheels of the vehicle and a traction control module. The example traction control module determines, based on measurements of the wheel speed sensors or a transmission control module, whether the vehicle is likely stuck. Additionally, when the vehicle is likely stuck and an indication to disable the a traction control system has been received, the example traction control module disables the traction control system.
