Apparatus for controlling a throttle plate of a carburetor of an internal combustion engine in response to loss of traction by a driving wheel, or other similar condition

摘要

An apparatus for controlling a throttle of an internal combustion engine of a vehicle receives a signal related to an actual position of the throttle, and a target throttle position signal produced in response to a condition of the vehicle, such as loss of traction of one or more driving wheels. A polyphase motor is connected to control the position of the throttle. A circuit, such as a programmed digital computer, is also provided that is responsive to the target throttle position signal for simultaneously applying driving signals to at least two windings of the polyphase motor to cause the polyphase motor to move the position of the throttle until the signal related to the actual position of the throttle indicates that the throttle is at a position indicated by the target throttle position signal.
