Title (EN) ENGINE STARTUP CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE DE DÉMARRAGE DE MOTEUR
(JA) エンジン始動制御装置
Abstract:
(EN) An engine startup control device (50) is provided with an overcome determination unit (61) which, if a startup request occurs during a rotation reduction period, executes an overcome determination on the basis of a state of rotation of an engine output shaft to determine whether a piston (13) in a cylinder (12) of an engine is capable of overcoming compression top dead center. Further, the engine start control device is also provided with a startup control unit (62) which, if it has been determined that the piston cannot overcome compression top dead center, causes an electric motor (30) to drive during a low reaction force period in which a reaction force applied to the piston as a result of cylinder pressure in the cylinder is at most equal to a prescribed reaction force, to cause the engine to start up.
(FR) Dispositif de commande de démarrage (50) de moteur pourvu d'une unité de détermination de surmontage (61) qui, si une demande de démarrage se produit pendant une période de réduction de rotation, exécute une détermination de surmontage sur la base d'un état de rotation d'un arbre de sortie de moteur pour déterminer si un piston (13) dans un cylindre (12) d'un moteur peut surmonter le point mort haut de compression. En outre, le dispositif de commande de démarrage de moteur est également pourvu d'une unité de commande de démarrage (62) qui, s'il a été déterminé que le piston ne peut pas surmonter le point mort haut de compression, amène l'entraînement d'un moteur électrique (30) pendant une période de faible force de réaction dans laquelle une force de réaction appliquée au piston à la suite d'une pression de cylindre dans le cylindre est au plus égale à une force de réaction prescrite, pour amener le moteur à démarrer.
(JA) エンジン始動制御装置(50)は、回転降下期間において、始動要求が生じた場合、エンジン出力軸の回転状態に基づいて、エンジンの気筒(12)内のピストン(13)が圧縮上死点を乗り越えられるか否かを判定する乗り越え判定を実行する乗り越え判定部(61)を備える。また、ピストンが圧縮上死点を乗り越えられないと判定された場合、気筒内の筒内圧によりピストンに加えられる反力が所定以下となる低反力期間で電動機(30)の駆動を開始させ、エンジンを始動させる始動制御部(62)と、を備える。
