Title (EN) ELECTRIC VEHICLE
(FR) VÉHICULE ÉLECTRIQUE
(JA) 電動車両
Abstract:
(EN) An electric vehicle, comprising a drive shaft outputting a drive force and at least two motors outputting a power to the drive shaft. The electric vehicle further comprises a control means which, when either of the motors is brought into a non-drive state, limits a torque to the motor in a drive state based on the counter electromotive force of the motor in the non-drive state. Thus, even when the electric vehicle in which a same shaft is driven by two or more motors runs continuously with one motor brought in the non-drive state, the circuit parts of an inverter can be properly protected.
(FR) La présente invention concerne un véhicule électrique qui comprend un arbre d’entraînement qui produit une force motrice et au moins deux moteurs qui produisent une puissance sur l’arbre d’entraînement. Le véhicule électrique comprend en outre un moyen de commande qui, lorsque l’un quelconque des moteurs est mis dans un état de non-entraînement, limite un couple sur le moteur dans un état d’entraînement sur la base de la force contre-électromotrice du moteur dans l’état de non-entraînement. Ainsi, même lorsque le véhicule électrique dans lequel un arbre identique est entraîné par deux moteurs ou plus fonctionne en continu avec un moteur mis dans l’état de non-entraînement, les parties de circuit d’un inverseur peuvent être correctement protégées.
(JA)  駆動力を出力する駆動軸と、該駆動軸に動力を出力する少なくとも2つの電動機とを備えた電動車両であって、いずれかの電動機が非駆動状態にある場合に、駆動状態にある電動機に対して前記非駆動状態の電動機の逆起電力に基づきトルク制限を実行する制御手段を備える。2つ以上の電動機によって同一軸を駆動する電動車両において、一方の電動機を非駆動状態にして走行を継続する場合でもインバータ等の回路部品を適切に保護することができる。
