Idle-stop restart control system
The idle-stop restart control system includes: a sensorless synchronous motor-generator which operates as a generator and a starting motor; an induced-signal detecting circuit for detecting an induced signal output from an armature winding; a field drive circuit for controlling energization of a field winding; and a restart control circuit output, to the field drive circuit, a drive signal for controlling the energization of the field winding to amplify the induced signal while calculating the number of revolutions and an angular position of a rotor based on the detected induced signal when an engine stop command is input and a level of the detected induced signal is equal to or less than a predetermined value and output the drive signal for controlling the energization of the armature winding to restart the engine based on the calculated number of revolutions and angular position of the rotor when a restart command is input.
