Abstract
An air suspension control system for a vehicle such as an ambulance, a bus or a semi-truck. The control system includes an air supply, such as a compressor, which is configured to pneumatically communicate with a lift mechanism for moving the lift mechanism between a ride height position and a kneeling position and vice versa. The controller is configured to return or recover the lift mechanism to its ride height position during the time the lift mechanism is moving from its ride height position to its kneeling position by only deactivating the kneel input. The controller is configured to return or recover the lift mechanism to its ride height position after the lift mechanism has reached kneeling position by both deactivating the kneel input and activating the recover trigger input by pressing the brake pedal. The control system also has a transmission park feature and an ignition timer feature.
