Abstract
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.
Claims20
A vehicle control system comprising:
- a plurality of ride height sensors that determine ride height information associated with individual wheels of a vehicle;
- a brake system that applies braking force to the individual wheels of the vehicle responsive to provision of a brake application signal;
- and
- a controller that generates the brake application signal during vehicle pitch based on vehicle speed and the ride height information.
A method of automatically applying electronic pitch stability control for a suspension system, the method comprising:
- determining pitch characteristics of a vehicle for a terrain profile and speed range via a lookup table associated with the vehicle;
- receiving ride height information from a plurality of ride height sensors associated with respective individual wheels of the vehicle;
- determining, based on the ride height information, vehicle speed and the lookup table, whether to generate a brake application signal;
- and
- applying braking forces to selected ones of the respective individual wheels of the vehicle responsive to generation of the brake application signal,
- wherein the lookup table includes speed values, ride height values, and corresponding braking force values and time for the braking forces to be applied.
