Abstract
(EN)
The drive control of the invention is applicable to a motor vehicle equipped with an engine, a first motor, a second motor, a planetary gear mechanism, a transmission, and an accumulator unit. In the motor vehicle, a sun gear, a carrier, and a ring gear of the planetary gear mechanism are respectively connected to the first motor, the engine, and a driveshaft, and the second motor is connected to the drive-shaft via the transmission. In response to a decrease in torque transmitted from the second motor to the driveshaft (that is, upon identification of a flag F 1 equal to '1' representing a torque phase) during an upshift operation of the transmission in the state of output of a positive torque from the second motor, the drive control of the invention lowers a target rotation speed Ne* of the engine to decrease a torque command Tm 1 *=(negative torque) of the first motor. This increases a direct torque Ter directly transmitted from the engine to the driveshaft by the first motor. The drive control then increases a torque command Tm 2 * of the second motor by a predetermined positive torque Tup and causes the second motor to consume at least part of electric power generated by the first motor under the condition of the increasing direct torque Ter. Such control effectively suppresses a decrease in torque applied to the driveshaft, while preventing excessive input of electric power into the accumulator unit.

La présente invention concerne une commande d'entraînement applicable à un véhicule à moteur équipé d'un moteur, d'un premier moteur, d'un second moteur, d'un mécanisme à engrenage planétaire, d'une transmission et d'un bloc accumulateur. Dans le véhicule à moteur, un planétaire, un support et une couronne de train planétaire du mécanisme à engrenage planétaire sont reliés respectivement au premier moteur, au moteur et à l'arbre de transmission, et le second moteur est relié à l'arbre de transmission (lequel, selon indication fournie par un drapeau F1 égal à 1, représente une phase de couple) pendant une opération de passage à un rapport supérieur de la transmission dans un état de production d'un couple positif depuis le second moteur. La commande d'entraînement décrite dans cette invention est conçue pour réduire une vitesse de rotation cible Ne* du moteur afin de réduire une commande de couple Tm1* (couple négatif) du premier moteur. Ce mode de réalisation permet d'augmenter un couple direct Ter directement transmis depuis le moteur à l'arbre de transmission par le premier moteur. La commande d'entraînement augmente ensuite une commande de couple Tm2* du second moteur par un couple positif prédéterminé Tup et permet au moteur de consommer au moins une partie de la puissance électrique générée par le premier moteur dans des conditions d'un couple direct Ter croissant. Une telle régulation permet d'éliminer efficacement une réduction du couple appliqué sur l'arbre de transmission, tout en empêchant une entrée excessive de puissance électrique dans le bloc accumulateur.
