Active Suspension Control

Definition

Active suspension control is a sophisticated system used in vehicles to actively manage and adjust the suspension settings in real-time for improved ride quality, stability, and handling. This technology allows for continuous monitoring of road conditions and vehicle dynamics, leading to optimal performance by adjusting the damping forces and ride height as needed. The effectiveness of active suspension control heavily relies on practical implementation considerations, including sensor integration, control algorithms, and overall system complexity.
