Adjustable damping control system for vehicle suspension during operation
A recently granted patent (Publication Number: US11970036B2) outlines a damping control method for vehicles with a suspension system, adjustable shock absorbers, and a stabilizer bar linkage. The method involves receiving user input for damping operation mode, monitoring vehicle conditions through sensors, detecting airborne events based on z-axis acceleration, and adjusting shock absorber damping characteristics accordingly. During airborne events, compression damping is increased based on event duration, and the stabilizer bar linkage stiffness is adjusted based on user-selected modes or sensor inputs. Additionally, the method includes detecting landing conditions, increasing rebound damping, and maintaining damping adjustments for a specified duration post-event.
The patent also covers the operation of the stabilizer bar linkage based on user-selected modes or sensor inputs to adjust stiffness, toggle between locked and unlocked conditions, and increase stiffness based on sensed vehicle movement characteristics like speed. The method aims to enhance vehicle stability and control during airborne and landing events by dynamically adjusting shock absorber damping and stabilizer bar linkage stiffness. By incorporating user preferences and real-time sensor data, the system can optimize vehicle performance and safety in various driving conditions. Overall, the patented technology offers a comprehensive approach to damping control in vehicles, ensuring a smooth and controlled driving experience across different terrains and situations.
