Abstract
Disclosed is a low cost air suspension adjustment system that employs a visible height indicator. The combination of an externally-viewable suspension height “green zone” or desired height indicator and automatic pressure control enables a low-cost simple height adjustment system. The height adjustment system of the present invention includes a PCU which can be a module that houses an ECU (electronic control unit with a microprocessor), at least one solenoid valve 16, a pressure sensor 18 and a remote control device to instruct the ECU.
Claims26
An air suspension control system comprising:
- an electronic control unit with a microprocessor;
- at least one air pressure sensor operatively connected to said electronic control unit;
- said at least one air pressure sensor being adapted to read air spring pressure of an air suspension;
- at least one solenoid valve operatively connected to said electronic control unit, said at least one solenoid valve being adapted to exhaust air from an air suspension;
- a visible height indicator adapted to visually display an air suspension height, said visible height indicator indicating an optimal range;
- an air supply adapted to be operatively coupled to said electronic control unit, said air supply adapted to supply air to the air suspension;
- a controller operated by an operator and operatively coupled to said electronic control unit, said controller instructing said electronic control unit to supply air from the air supply to raise the air suspension or operate said solenoid valve to exhaust air to lower the air suspension to a desired height range within said height indicator optimal range;
- said electronic control unit storing said desired pressure range, said electronic control unit being adapted to maintain the air suspension within said desired range.
