Abstract
(EN)
This electric vehicle drive system includes an internal combustion engine, an electricity generation motor disposed so as to be capable of generating electricity by receiving motive power from the internal combustion engine, and a travel motor disposed so as to be capable of being driven by the electricity generated by the electricity generation motor. The electric vehicle drive system is configured such that the internal combustion engine and a driving wheel are disconnectably connected by means of a first clutch and the travel motor and the driving wheel are disconnectably connected by means of a second clutch different from the first clutch, thereby allowing switching between a series hybrid mode in which the vehicle is caused to travel by transmitting the motive power from the travel motor serving as a driving source to the driving wheel, and an engine direct-connection mode in which the vehicle is caused to travel by making at least one from among the internal combustion engine and a generator serve as a driving source and transmitting the motive power from the driving source to the driving wheel. The electric vehicle drive system engages both the first and second clutches when switching between the series hybrid mode and engine direct-connection mode, and changes, while both the first and second clutches are engaged, the proportion of internal combustion engine torque and the proportion of travel motor torque in the total vehicle driving torque to the proportion after the mode switching. When the proportion approximates to or reaches the proportion after the mode switching, the electric vehicle drive system disengages a disengagement-side clutch from among the first and second clutches.

L'invention concerne un système de propulsion de véhicule électrique comprenant un moteur à combustion interne, un moteur de production d'électricité disposé de manière à pouvoir produire de l'électricité par réception d'une puissance motrice en provenance du moteur à combustion interne, et un moteur de déplacement disposé de manière à pouvoir être entraîné par l'électricité produite par le moteur de production d'électricité. Le système de propulsion de véhicule électrique est conçu de telle sorte que le moteur à combustion interne et une roue motrice sont reliés de manière séparable au moyen d'un premier embrayage, et le moteur de déplacement et la roue motrice sont reliés de manière séparable au moyen d'un deuxième embrayage différent du premier embrayage, ce qui permet la commutation entre un mode hybride en série, dans lequel le véhicule est amené à se déplacer en transmettant la puissance motrice provenant du moteur de déplacement servant de source d'entraînement à la roue motrice, et un mode de connexion directe de moteur, dans lequel le véhicule est amené à se déplacer en amenant au moins un élément parmi le moteur à combustion interne et un générateur à servir de source d'entraînement et en transmettant la puissance motrice de la source d'entraînement à la roue motrice. Le système de propulsion de véhicule électrique embraye les premier et deuxième embrayages lors de la commutation entre le mode hybride en série et le mode de connexion directe de moteur, et, tandis que les premier et deuxième embrayages sont embrayés, change la proportion de couple de moteur à combustion interne et la proportion de couple de moteur de déplacement dans le couple d'entraînement de véhicule total à la proportion après la commutation de mode. Lorsque la proportion se rapproche ou atteint la proportion après la commutation de mode, le système d'entraînement de véhicule électrique débraye un embrayage côté débrayage parmi les premier et deuxième embrayages.
