RIDE PERFORMANCE OPTIMIZATION IN AN ACTIVE SUSPENSION SYSTEM

摘要

An active vehicle suspension system includes an active damping mechanism operatively coupled to a vehicle wheel and configured for controlling a damping force applied to the wheel responsive to a control signal. A controller is operatively coupled to the damping mechanism and configured for generating a control signal to the damping mechanism responsive to velocity of the wheel in a downward vertical direction.

主权项

1. A method of controlling a vehicle suspension for a wheel via a controller, the method comprising:
repeatedly calculating a vertical velocity of the wheel until the vertical velocity exceeds a first velocity threshold; in response to the vertical velocity exceeding the first velocity threshold, initiating a timer and maintaining a damping level of an adjustable damping mechanism of the vehicle suspension at an initial value while repeatedly recalculating the vertical velocity of the wheel until the recalculated vertical velocity exceeds a second velocity threshold; and in response to the recalculated vertical velocity exceeding the second velocity threshold before the timer exceeds a first time threshold, sending an adjustment signal to the adjustable damping mechanism of the vehicle suspension to increase the damping level of the suspension.
