Abstract

A voltage regulating control system for vehicle systems which includes a power supply providing electrical power to the system and having a predefined maximum voltage. A controller controls an actuator performing a vehicle system function and the electrical load in the system wherein the controller has a first predefined minimum operating voltage. A voltage regulator communicates with the controller and the power supply and senses a system input voltage in the system. In response to a sensed voltage dip in excess of a predetermined value, the regulator changes an effective electrical impedance of the system to maintain the system voltage at a predefined minimum voltage greater than the first predefined minimum operating voltage required by the controller.
