VEHICULAR CONTROL SYSTEM WITH CONSTANT POWER OUTPUT

A vehicular power system includes a battery disposed at a vehicle, an electrical motor disposed at the vehicle that controls propulsion of the equipped vehicle when powered, a power system controller, and a transformer electrically connected to the battery. The transformer includes a plurality of taps, each tap of the plurality of taps providing a different output voltage. The power system controller, responsive to a vehicle speed request, determines one of the plurality of taps. The power system controller electrically connects the determined one of the plurality of taps to the electrical motor, and electrical power flows from the battery through the determined one of the plurality of taps to the electrical motor. The electrical motor, based on the electrical power from the determined one of the plurality of taps, adjusts speed of propulsion of the equipped vehicle toward the requested vehicle speed.
