Bike rack

An air pressure control system for the passenger compartment of a vehicle including an open-loop for generating an open-loop valve position command, a closed-loop for generating a closed-loop correction signal, and a valve control for positioning a valve as a combined function of the open-loop position command and the closed-loop correction command, thereby regulating the flow of air from the passenger compartment and the compartment pressure.

Air pressure control

A motor vehicle passenger compartment has an air inlet at the base of the windshield and a valve controlling an air outlet so as to maintain the pressure in the compartment above ambient pressure.
