ABSTRACT:
An electrical system for increasing the amount of voltage available to an electric power steering motor under high demand conditions includes a vehicle speed sensor that ascertains the speed of the vehicle, a steering wheel sensor that ascertains the rotational speed of the vehicle steering wheel, and a steering voltage controller that receives the signals provided by the vehicle speed sensor and the steering wheel sensor and processes these input signals to increase the voltage furnished to the power steering system by causing at least one component that consumes electrical power in the vehicle to reduce power consumption, or by causing a component that produces electrical power to increase power output, or by a combination of reducing power consumption and increasing power production. The present method increases the voltage available to an electric power system steering system by sensing vehicle speed and steering wheel rotational speed, by determining whether these conditions indicate a demand for greater power steering assist, and by managing electric load and power output to provide more voltage to the electric power steering motor when high demand for power assistance and torque is indicated.
