Distributed Motor Torque Generation System and Method of Control

摘要

An apparatus for an electrically powered terrestrial vehicle applies electrical energy to front wheels and to rear wheels. A control system receives desired acceleration inputs and provides target torque requirements to a plurality of adaptive field-oriented motor control circuits. One or more three-phase alternating current synchronous motors receive voltage magnitude and voltage frequency to generate torque, which is applied through a reduction gear. One motor only may be powered during certain modes of operation.

1. An apparatus for controlling an adaptive field-oriented electric motor comprising:
a current speed determination circuit; a desired acceleration determination circuit; a torque generation distribution circuit; and a voltage magnitude and voltage frequency determination circuit; whereby only front wheel adaptive field-oriented motor control circuits receive voltage magnitude and voltage frequency torque generation signals when a threshold speed has been attained and no further acceleration is desired, and whereby only rear wheel adaptive field oriented motor control circuits receive voltage magnitude and voltage frequency torque generation signals when acceleration is desired and a threshold speed has not been exceeded.
