Title:
RESTARTING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/208975
Kind Code:
A1
Abstract:
A restarting control system equipped with: a rotation angle estimation unit (23, 22, 30) that estimates the rotation angle of a rotary electric machine (20) when the rotational speed of an internal combustion engine (10) as detected by a rotational speed detection unit (45) is higher than an estimation threshold value, and that does not estimate the rotation angle of the rotary electric machine when the rotational speed is lower than the estimation threshold value; a rotary electric machine control unit (22, 30) that, on the condition that a prescribed restarting condition has been fulfilled and the rotation angle of the rotary electric machine has been estimated by the rotation angle estimation unit, increases the rotational speed of the internal combustion engine by means of the rotary electric machine, thereby restarting the internal combustion engine; and a starter motor control unit (30) that, on the condition that the prescribed restarting condition has been fulfilled and the rotational speed of the internal combustion engine has fallen below a prescribed rotational speed that is set so as to be less than the estimation threshold value, begins driving a starter motor (11) and increases the rotational speed of the internal combustion engine to the estimation threshold value.
