Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle stability control systems do not allow drivers to completely turn off or adjust the stability control level, which can be limiting in certain driving situations, such as driving on a track.
Innovation Solution
A vehicle stability control device and method that includes an input unit for receiving a stability control level, a receiving unit for receiving vehicle driving information, and a stability control unit that controls driving force and braking force based on the stability control level and driving information, including yaw rate and wheel slip information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stability control is activated to prevent wheel slip and improve driving stability, then vehicle safety is improved, but driver ability to adjust control level is reduced
Solution Approach 1:
The stability control system transitions from a static on/off state to a dynamic multi-level control system. The controller receives stability control level information indicating different levels (first level with higher control amount, second level with lower control amount) and dynamically adjusts the control amount based on the selected level, allowing the system to adapt its stabilization intensity to match different driving conditions and driver preferences.
2Stability of the object's composition
If stability control applies strong braking force to correct yaw rate deviations, then vehicle directional stability is improved, but driver input responsiveness is reduced
Solution Approach 1:
The system changes the parameter of control amount based on stability control level. When the stability control level indicates the first level, the controller executes stability control with a higher control amount; when it indicates the second level, the controller executes stability control with a lower control amount. This parameter adjustment allows the system to provide stronger stabilization when needed while maintaining driver responsiveness during normal operation.
