Control logic for fluid flow control devices

摘要

A system for controlling a fluid flow control device positioned on a surface of a vehicle. The system includes a fluid flow control device, a ground clearance sensor and a controller. The fluid flow control device has a body with at least one surface and an actuation means in operative communication with the at least one surface. The actuation means is operative to alter at least one attribute of the fluid flow control device in response to a control signal. The ground clearance sensor detects a clearance between the surface of the vehicle and a road. The controller has control logic for generating the control signal in response to the ground clearance sensor. The clearance may be a current clearance between the surface of the vehicle and the road and/or a predicted imminent clearance between the surface of the vehicle and the road.
