Drive Controller Power Adaptation for Consistent Vehicle Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle platforms require complex and costly drive regulations for different vehicle types, leading to inconsistencies in achieving specified driving performance due to variations in size and weight, and existing methods do not efficiently adapt driving performance across vehicle types.
Innovation Solution
A method involving defining desired driving performance, base driving resistance, drive motor behavior, and calculating nominal drive power, regulated by a drive controller, simplifies the adaptation of driving performance across vehicle types by standardizing steps A to E, with optional additional resistance calculations using sensors for real-time adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a special drive regulation is provided for each vehicle type based on a vehicle platform, then the specified driving performance can be achieved, but the complexity and cost of drive regulation increases
Solution Approach 1:
The patent applies universality by creating a single standardized drive regulation that can be used across multiple vehicle types on a common platform. The method defines universal parameters (base driving resistance, drive motor behavior, desired driving performance) that can be adapted to different vehicle types without requiring separate regulations for each vehicle, thus reducing complexity while maintaining performance achievement.
Solution Approach 2:
The patent uses parameter changes by allowing the standardized drive regulation to adapt to different vehicle types through modifying input parameters such as base driving resistance values and desired driving performance specifications. This enables a single regulation framework to handle multiple vehicle configurations by changing parameters rather than creating entirely separate regulations.
2Device complexity
If an identical drive regulation is used for all vehicles on a platform, then the complexity and cost is reduced, but not all vehicles achieve the specified driving performance
Solution Approach 1:
The patent applies local quality by allowing the drive regulation to have uniform structure across all vehicle types while enabling local adaptations through vehicle-specific parameters. The base driving resistance and desired driving performance can be locally adjusted for each vehicle type based on its specific characteristics (weight, dimensions, performance requirements), ensuring each vehicle achieves its specified performance while maintaining overall system simplicity.
3Reliability
If vehicle-specific parameters are defined for each vehicle type, then accurate driving performance can be achieved, but the method complexity and implementation cost increases
Solution Approach 1:
The patent applies segmentation by dividing the drive regulation method into distinct, manageable steps: defining base driving resistance, defining drive motor behavior, defining desired driving performance, calculating nominal drive power, and regulating current drive power. This structured segmentation makes the implementation systematic and reduces errors while maintaining the ability to achieve accurate vehicle-specific performance through parameter definition in each step.
