Vehicle control system and method of controlling a vehicle system
First Claim
1. A vehicle control system comprising:
- a vehicular steering mechanism adapted to be operatively connected to associated wheels of a vehicle;
at least one steering position sensor operatively connected to said steering mechanism for generating a steering position signal representative of a position of said steering mechanism;
an on-center controller having a filter device which receives said steering position signal, filters said steering position signal to eliminate at least one of noise and low frequency changes in said steering position signal, and then generates a filtered output signal;
an electronic control unit in communication with said on-center controller, said electronic control unit operative to generate a control signal based at least in part upon said filtered output signal; and
a vehicle suspension system having at least one selectively lockable suspension actuator, said at least one selectively lockable suspension actuator being selectively controlled by said control signal generated by said electronic control unit;
wherein said on-center controller further includes an on-center velocity processor which receives said filtered output signal and a signal received from a vehicle speed sensor and generates an output signal, whereby said electronic control unit is operative to generate said control signal, based at least in part upon said output signal received from said on-center velocity processor, to said at least one selectively lockable suspension actuator of said suspension system.

Abstract
A vehicle control system includes a steering mechanism adapted to be operatively connected to associated wheels of a vehicle. A position sensor is operatively connected to the steering mechanism to generate a signal representative of a position of the steering mechanism. A filter device receives the steering position signal and generates a filtered output. The electronic control unit is operable to generate a control signal based at least in part upon the filtered steering position signal. A vehicle control subsystem is in communication with the electronic control unit and is responsive to the control signal. A vehicle system is controlled by monitoring the position of a steering mechanism of a vehicle, determining a rate of change of the position of the steering mechanism, filtering the rate of change, comparing the filtered rate of change to a threshold value, and controlling a vehicle system based upon the comparison.
