| Summary: | A method for limiting endstop collisions when non-typical inputs are experienced and also when the seat is leveled at a position above or below the normal leveling zone limits. According to the method of the invention a temporary or transient control method referred to as rebound control method causes a large damping force to be applied by the seat suspension system in response to non-typically large inputs. The large damping force is applied until a duration timer timesout. Also according to the invention, a level control algorithm provides additional damping when the seat is leveled outside the normal leveling zone. The degree of additional damping provided is a function of the distance the seat exceeds the normal leveling zone. |
