Clutch Control Apparatus Sliding Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clutch control systems for vehicles may reduce rider convenience due to improper clutch engagement and disengagement, leading to temporary sliding and potential malfunctions, which can disrupt vehicle travel.
Innovation Solution
A clutch control apparatus that stops actuator control when the rotational speed difference between the driving and driven members exceeds a predetermined value, maintaining the engaged state until the difference decreases below a second value within a set time, allowing for resumed control and continued vehicle travel after temporary sliding is eliminated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clutch control apparatus continuously controls the actuator to maintain engagement, then the clutch engagement smoothness is improved, but temporary sliding between plates occurs reducing rider convenience
Solution Approach 1:
The control approach dynamically adapts based on detected sliding conditions. When temporary sliding is detected through rotational speed comparison, the control system transitions from continuous actuation to a pause state, then resumes control when sliding ceases. This dynamic adjustment prevents the harmful effects of continuous control during sliding while maintaining engagement smoothness during normal operation.
Solution Approach 2:
The system implements feedback by continuously monitoring the rotational speed difference between driving and driven members. When the difference exceeds a threshold indicating sliding, the control system receives feedback to pause actuator control. When the difference returns within acceptable limits, feedback triggers resumption of control, creating a closed-loop system that responds to actual clutch conditions.
2Measurement precision
If the control system monitors rotational speed difference continuously, then temporary sliding detection accuracy is improved, but control system complexity increases
Solution Approach 1:
The system uses the rotational speed difference as an intermediary parameter to detect sliding conditions indirectly. Instead of directly sensing plate sliding, the control apparatus compares the rotational speeds of the driving member (engine side) and driven member (transmission side), using this speed difference as a mediator to infer sliding states and trigger appropriate control responses.
Solution Approach 2:
The patent replaces direct mechanical sensing of clutch plate sliding with an electronic control system that calculates sliding conditions based on rotational speed data. This substitution eliminates the need for complex mechanical sensors within the clutch assembly, using instead electronic sensors and computational logic to achieve equivalent or superior detection accuracy with reduced mechanical complexity.
