Speed dependent control for dual air spring configuration |
摘要 |
An air suspension system is configured to maintain a desired vehicle comfort ride level as a function of vehicle speed. The air suspension system includes a plurality of air spring assemblies that each include a piston airbag and a primary airbag mounted around the piston airbag. A first set of the air spring assemblies is tuned to a first ride rate and a second set of the air spring assemblies is tuned to a second ride rate. Pressure is continuously varied within the first and second sets of air springs to maintain a first predetermined ride rate difference between the first ride rate and the second ride rate under a low vehicle speed condition and to maintain a second predetermined ride rate difference between the first ride rate and the second ride rate under a high vehicle speed condition.
