A vehicle control system includes a plurality of ride height sensors, a brake system and a controller. The ride height sensors may determine ride height information associated with individual wheels of a vehicle. The brake system may apply braking force to the individual wheels of the vehicle responsive to provision of a brake application signal. The controller may generate the brake application signal during vehicle pitch based on vehicle speed and the ride height information.

Suspension system with electronic pitch stability control

A vehicle control system includes a plurality of sensors that determine ride height information of a vehicle, a sensor that determines pitch information for the vehicle, and a controller that selectively applies traction torque and braking torque to wheels of the vehicle based on vehicle speed, the pitch information and the ride height information.

Suspension system with comprehensive pitch stability control

A suspension assembly for a vehicle suspension system may include a lower control arm, an upper control arm, a damper, and a drop link. The lower control arm may be operably coupled to a chassis of a vehicle via a first bushing assembly and a second bushing assembly. The first and second bushing assemblies may each pivot about an axis substantially parallel to a longitudinal centerline of the vehicle. The upper control arm may be operably coupled to the chassis. The damper may be operably coupled to the lower control arm to dampen pivoting motion of the upper and lower control arms relative to the chassis. The drop link may operably couple the lower control arm and an anti-roll bar that includes a disconnect assembly to translate a roll motion into a force exerted on the lower control arm in a direction substantially parallel to the axis.

ARB disconnect system with improved roll gradient and understeer characteristics

A method of optimizing a suspension system to avoid pitch resonance may include determining pitch characteristics of a vehicle for a terrain profile and speed range via a model associated with the vehicle, decoupling front and rear axles by removing pitch inertia from the model, and determining optimized damping for a main damper of a position sensitive damper over a linear range of wheel travel in a bounce control zone based on the pitch characteristics. The method may further include recoupling the front and rear axles by adding the pitch inertia back into the model, and selecting a secondary damper associated with a compression zone or a secondary damper associated with a rebound zone as a selected damper for adjustment based on which of the front and rear axles is limiting. The method may also include performing a damping adjustment to the selected damper and cyclically repeating selecting the secondary damper and performing the damping adjustment until pitch resonance is suppressed.
