Modular and Expandable Air Management System

An air suspension control system utilizes a suspension control module, one or more pneumatic control modules, and an end cap for controlling air-spring suspension units of different configurations. The system is expandable, and each pneumatic control module has an integrated air-spring pressure sensor, and an electrical connector to connect with an electronic height sensor. The system can level the suspension units based on air-spring pressure or air-spring height. The system is wireless enabled to provide connectivity to smartphone apps and dedicated devices for user interface, and allows for wireless updating of firmware.
