Abstract:
(EN) Provided is a control device for an electric vehicle, the device being capable of suppressing vehicle destabilization caused by the rear wheels locking first or suppressing a deterioration in driving performance caused by the front wheels locking too soon. The control device comprises: a regenerative braking force calculating unit that calculates regenerative braking force generated by a front motor and a rear motor on the basis of demanded braking force demanded by the electric vehicle; a power limiting unit that reduces the regenerative braking force on the basis of the power limit of a power source; and a friction braking force outputting unit that outputs, to a brake device, a command to generate friction braking force in accordance with a regenerative braking force reduction amount, which is the amount by which the regenerative braking force is reduced by the power limiting unit.
(FR) L'invention concerne un dispositif de commande pour un véhicule électrique, le dispositif étant susceptible d'éliminer une déstabilisation de véhicule provoquée par le blocage premier des roues arrière ou d'éliminer une détérioration des performances de conduite provoquée par le blocage précoce des roues avant. Le dispositif de commande comprend : une unité de calcul de force de freinage par récupération qui calcule une force de freinage par récupération produite par un moteur avant et un moteur arrière sur la base d'une force de freinage demandée, demandée par le véhicule électrique ; une unité de limitation de courant qui réduit la force de freinage par récupération sur la base de la limite de courant d'une source d'alimentation ; et une unité de sortie de force de freinage par friction qui délivre à un dispositif de frein une instruction de manière à produire une force de freinage par friction en fonction d'une quantité de réduction de force de freinage par récupération, qui est la quantité de laquelle la force de freinage par récupération est réduite par l'unité de limitation de courant.
(JA) 後輪が先にロックすることによる車両の不安定化もしくは前輪が早期にロックして運転性が低下することを抑制可能な電動車両の制御装置を提供すること。 制御装置は、電動車両に要求される要求制動力に基づいてフロントモータとリアモータとに発生させる回生制動力を演算する回生制動力演算部と、回生制動力を電力源の電力制限に基づいて低減する電力制限部と、電力制限部による回生制動力の低減量である回生制動力低減量に応じた摩擦制動力を発生させる指令をブレーキ装置に出力する摩擦制動力出力部と、を備える。
