Title:
DRIVE CONTROL SYSTEM AND METHOD FOR CONTROLLING DRIVE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/142578
Kind Code:
A1
Abstract:
According to the present invention, a control unit of a drive control system, by driving a motor after power is turned on, causes an internal combustion engine to rotate by imparting thereto a standard torque that exceeds a second top dead center between an exhaust stroke and an intake stroke of the internal combustion engine and that does not exceed a first top dead center between a compression stroke and a combustion stroke of the internal combustion engine, and, after having imparted the standard torque by driving the motor, detects a standard position corresponding to the top dead center of the internal combustion engine on the basis of U-, V-, and W-phase detection signals respectively outputted by U-, V-, and W-phase sensor elements, in accordance with the rotation of the motor and also on the basis of pulse information including a pulse wave outputted by a pickup coil in accordance with the rotation of the motor.
