AUTOMATIC CONTROL OF THROTTLE BY SERVO APPARATUS
A servo apparatus for automatic control of vehicle engine speed, in accordance with a speed error signal, has an electric motor connectable to open the engine throttle against a restoring force, and the motor torque is controlled by varying the pulse width of the motor drive current. The pulse width...

| description | A servo apparatus for automatic control of vehicle engine speed, in accordance with a speed error signal, has an electric motor connectable to open the engine throttle against a restoring force, and the motor torque is controlled by varying the pulse width of the motor drive current. The pulse width is controlled by the error signal through a feedback stabilized amplifier and in addition, motor back emf is sampled and used to control the pulse width during motor braking phases. |
