Vehicle suspension control system
First Claim
1. For use with a motor vehicle having at least one fluid-pressurized height adjusting member having first and second separable components, an integrated vehicle ride height system controller apparatus comprising:
- a) electronic output drive signal circuitry and input signal interpretation circuitry to electronically interface with at least one position sensor which provides output signals related to extent of separation of said first and second separable components of said at least one fluid pressurized height adjusting member;
b) electronic input and/or output circuitry to interface with at least one fluid pressure sensor which provides output signals related to said at least one fluid-pressurized height-adjusting member;
c) electronic output circuitry to actuate one or more fluid flow valves which apply pressure to said at least one fluid-pressurized height adjusting member to actuate raising thereof and wherein said one or more fluid flow valves release pressure from said at least one fluid-pressurized height adjusting member to actuate lowering thereof;
d) electronic output circuitry to drive output power control for said at least one fluid pressure pump to provide system fluid power; and
e) electronic circuitry incorporating control instructions for vehicle height control output functions in response to vehicle input signals.
