Low-Speed Vehicle Torque Control for Minimal Terrain Disruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low-speed electric vehicles (LSVs) cause environmental damage due to wheel traction and terrain disruption, especially in natural areas, and lack adaptive operational profiles to minimize their environmental impact.
Innovation Solution
Equipping LSVs with a set of sensors and a vehicular controller that adjusts operational parameters based on environmental data, including torque profiles, to minimize environmental impact by optimizing wheel traction, reducing noise, and adapting to different terrains.

Engineering Contradiction Analysis
1Speed
If LSVs engage power for acceleration or braking in natural terrain, then the vehicle can traverse the area, but the wheels rip up the terrain causing environmental damage
Solution Approach 1:
The system dynamically adjusts operational parameters including power engagement timing, torque profiles, and speed control based on real-time sensor data about terrain conditions. The vehicular controller continuously modifies these parameters to optimize traversal while minimizing terrain disruption, transitioning between different operational states rather than using fixed settings.
Solution Approach 2:
The system changes physical parameters such as torque magnitude, power delivery timing, and vehicle speed based on environmental conditions. By adjusting these parameters dynamically, the vehicle can traverse different terrain types (pavement, lawn, slopes) while minimizing harmful effects like wheel rip-up and terrain damage.
2Adaptability or versatility
If LSVs operate in areas with significant terrain differences, then the vehicle can access diverse areas, but the operator may engage power in a manner that is dangerous or not environmentally sound
Solution Approach 1:
The system uses sensor feedback about terrain conditions, vehicle state, and environmental factors to continuously adjust operational parameters. This closed-loop control enables the vehicle to adapt to diverse terrains while maintaining safe operation, as the controller receives real-time information and modifies power engagement and torque delivery accordingly.
Solution Approach 2:
The system performs preliminary assessment of terrain conditions using sensors before engaging power or making significant operational changes. This allows the vehicle to prepare appropriate torque profiles and power engagement strategies in advance, preventing dangerous operation in challenging terrain while maintaining versatility across different environments.
3Device complexity
If LSVs use traditional operational modes, then the vehicle maintains simple control, but the environmental impact cannot be minimized
Solution Approach 1:
The system enables the vehicle to automatically adjust its own operational parameters without requiring complex operator intervention. The vehicular controller autonomously manages torque profiles, power engagement timing, and speed control based on sensor data, allowing the vehicle to minimize environmental impact while maintaining relatively simple overall system architecture.
