  • Patent number: 4555126
    Abstract: An improved vehicle suspension system capable of providing at all times a desirable maneuvering characteristic variable in response to changes in the angle of steering. The suspension system includes front wheel suspension assemblies for resiliently suspending the front wheels of the vehicle and rear wheel suspension assemblies for resiliently suspending the rear wheels of the vehicle. The front wheel suspension assemblies and/or the rear wheel suspension assemblies have a variable suspension characteristic which is controlled to vary in response to a steering angle exceeding a predetermined level in a manner such that the steering characteristic of the vehicle during steering operation is changed in a direction toward an oversteer characteristic as compared with the steering characteristic during non-steering operation.
