Vehicle Paddle Shift Mode Switching for Direct Auto-Manual Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control mode switching apparatuses in vehicles require multiple operations and mode confirmations to switch between control modes, making the process cumbersome and inefficient.
Innovation Solution
A control mode switching apparatus that utilizes a pair of paddle shift levers and a control unit to determine the aspect of operation, allowing direct switching between non-control, auto, and manual modes based on the operation aspect, eliminating the need for intermediate mode confirmations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a driver operates multiple types of operators in aspects different in accordance with current mode to switch control mode, then the control mode can be switched among three modes, but the switching process becomes cumbersome and time-consuming
Solution Approach 1:
The paddle shift lever is designed to perform multiple functions: it can switch between non-control mode and auto mode, between non-control mode and manual mode, and between auto mode and manual mode. This multi-functional design eliminates the need for separate operators for each mode transition, allowing a single operator to handle all switching operations among the three control modes.
Solution Approach 2:
The control unit dynamically determines the aspect of operation based on the current control mode and the driver's input direction. The system adapts its response to the same physical input depending on the current state, enabling flexible mode transitions without requiring the driver to learn multiple operating procedures for different modes.
2Reliability
If the system requires confirmation of current mode before operation, then mode switching can be controlled, but the switching process becomes slower and less efficient
Solution Approach 1:
The control unit continuously monitors and determines the current control mode in advance, so when the driver operates the paddle shift lever, the system is already prepared to execute the appropriate mode transition. This eliminates the need for real-time mode confirmation during the switching operation, reducing delays while maintaining accurate control.
Solution Approach 2:
The control unit provides continuous feedback about the current control mode to the switching logic, enabling the system to automatically determine the appropriate transition based on the driver's input direction and current state. This feedback mechanism ensures reliable mode switching without requiring explicit driver confirmation, thereby reducing switching time.
