Vehicle Clutch Control with Multi-Mode Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power transmission devices for vehicles lack the ability to offer multiple manual clutch operating modes, failing to accommodate diverse driver skills and preferences, such as enjoying manual clutch operations or requiring precise control, which limits the versatility and safety of driving experiences.
Innovation Solution
A power transmission device with a control unit that allows for automatic clutch engagement/disengagement and includes both manual and automatic modes, with selectable control modes for varying levels of automatic intervention, enabling comfortable or precise clutch operations based on driver skill and situation, and incorporates a driving skill determining device to adjust settings accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single manual clutch operating mode is provided, then the device structure remains simple, but it fails to accommodate diverse driver skills and preferences
Solution Approach 1:
The clutch control system transitions from a static single-mode design to a dynamic multi-mode system that can adapt its characteristics based on driver skill level and driving conditions, allowing the same hardware to provide different control behaviors through software-based mode switching
Solution Approach 2:
The clutch control device is designed to perform multiple functions by incorporating different control modes (manual mode with varying intervention levels, automatic mode) within a single system, making it universally applicable to drivers of all skill levels and various driving scenarios
2Ease of operation
If automatic control intervention is increased to assist drivers, then driving comfort improves, but the driver's ability to learn and master precise clutch operations is reduced
Solution Approach 1:
The control intervention level is made dynamic and adjustable rather than fixed, allowing the system to provide varying degrees of assistance based on the selected mode, thereby balancing comfort and skill development needs
Solution Approach 2:
The control system is segmented into distinct modes (manual mode with adjustable intervention, automatic mode) that can be independently selected, allowing drivers to choose between comfort-oriented and skill-development-oriented operation characteristics
3Adaptability or versatility
If multiple control modes with differing intervention levels are added, then versatility for different driver needs is improved, but the control system complexity increases
Solution Approach 1:
A single clutch control device is designed to universally serve multiple driving needs and skill levels by integrating various control modes (manual with different intervention levels, automatic) within one system, eliminating the need for multiple separate devices
Solution Approach 2:
The control system employs dynamic mode switching capabilities that allow transition between different intervention levels and operating characteristics without requiring physical reconfiguration, managing complexity through software-based adaptability

AI summary
A power transmission device for a vehicle includes a control unit adapted to automatically control engagement or disengagement of a clutch, and is further equipped with a clutch lever for manually engaging or disengaging the clutch. The power transmission device includes a manual mode in which the clutch is engaged or disengaged by a driver performing an engagement or disengagement operation with the clutch engagement/disengagement operating element and an automatic mode in which the clutch is engaged or disengaged under the control of the control unit without the driver performing the engagement or disengagement operation. The manual mode or the automatic mode is selectable by the driver. In the manual mode, it is further possible to select a plurality of control modes with differing levels of intervention of the automatic control.
