Automatic suspension control system for motor vehicles

摘要

A vehicle ride-height and automatic suspension control system for a vehicle having an air suspension system. The automatic suspension control system provides the vehicle operator with selectable ride-heights and controls vehicle level as it rounds curves or corners. The system utilizes a series of photoelectric sensors that are linked between the vehicle chassis and axles and are combined with the vehicle steering system. Continuously sampling of the photoelectric sensors by a controller increments or decrements a digital register. When the counter reaches either the upper or lower selected threshold values the appropriate air bag is inflated or deflated for a duration of time. System sensitivity is adjustable by selecting different counter thresholds and by selecting the duration of air bag inflation or deflation.
