Vehicle Torque Control for Load Engagement and Slip Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traction control systems in vehicles are inadequate in preventing wheel slippage, as they are reactionary and do not proactively manage torque, leading to increased wear and inefficiencies, especially when engaging loads, and inexperienced operators may struggle to manage controls effectively.
Innovation Solution
An automatic torque control system that includes a controller detecting when a vehicle engages a load and proactively decreases torque to a base setting before wheels slip, based on the type of ground surface, and increases torque back to maximum when the load is disengaged, using a combination of sensors and pre-defined torque settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If maximum torque is provided to the wheels for various operations, then the vehicle can accelerate and travel at high speeds, but the wheels may slip and lead to increased wear
Solution Approach 1:
The controller proactively reduces torque to a pre-determined safe level when it detects that the vehicle is engaging a load, before wheel slippage can occur. This preliminary action prevents the harmful effect of wheel slip and associated wear while still allowing the vehicle to maintain operational capability.
Solution Approach 2:
The system continuously monitors vehicle operation and detects when the vehicle engages a load, then automatically adjusts torque accordingly. This closed-loop feedback mechanism enables the controller to respond to changing conditions and maintain optimal torque levels that prevent wheel slippage.
2Reliability
If current traction control systems reduce torque in response to wheel slippage, then wheel slippage is addressed, but the systems are reactionary and inadequate for preventing slippage
Solution Approach 1:
Instead of waiting for wheel slippage to occur and then reacting, the system performs a preliminary action by detecting load engagement and proactively reducing torque to a safe level before slippage can happen. This eliminates the time delay inherent in reactionary systems.
Solution Approach 2:
The system applies a preliminary anti-action by reducing torque in anticipation of potential slippage conditions. When the vehicle engages a load, the controller preemptively lowers torque to prevent the harmful effect rather than correcting it after it occurs.
3Adaptability or versatility
If manual torque adjustment settings are provided, then operators can adjust torque based on ground surface type, but inexperienced operators may not know how to manage the controls or when to engage specific settings
Solution Approach 1:
The system performs the torque adjustment function automatically without requiring operator intervention. The controller monitors vehicle operation, detects load engagement, and self-adjusts torque to appropriate levels, eliminating the need for operator knowledge of when and how to adjust torque settings.
Solution Approach 2:
The system has pre-programmed torque reduction levels for different operating conditions. When load engagement is detected, the controller automatically applies the appropriate pre-determined torque setting, eliminating the need for the operator to manually select or adjust settings based on ground surface type or vehicle conditions.
