Description

DISPOSITIF DE COMMANDE DE TRANSMISSION AUTOMATIQUEAUTOMATIC TRANSMISSION CONTROL DEVICE

La présente invention concerne un dispositif de commande de transmission automatique.The present invention relates to an automatic transmission control device.

JP 2019-55771 A divulgue que, afin de minimiser la décélération d'un véhicule perçue par un occupant du véhicule pendant une phase de changement de rapport et, en même temps, de réduire la consommation d'énergie d'un moteur électrique, lorsqu'une valeur de couple maximale qui peut être transmise par le moteur électrique est inférieure à une valeur de couple initiale transmise aux roues par un moteur thermique juste avant le début de la phase de changement de rapport, un embrayage à friction est progressivement désengagé au cours d’une période de temps jusqu'à ce que le couple transmis aux roues par le moteur thermique atteigne une valeur de couple réduite qui soit sensiblement égale à la valeur de couple maximale pouvant être transmise par le moteur électrique, l'embrayage à friction est progressivement engagé pendant une période de temps jusqu'à ce que le couple transmis aux roues par le moteur thermique passe de la valeur de couple réduite à la valeur de couple initiale, et le moteur électrique ne transmet aucun couple au cours de chaque période de temps.JP 2019-55771 A discloses that, in order to minimize the deceleration of a vehicle perceived by a vehicle occupant during a shift phase and, at the same time, to reduce the energy consumption of an electric motor, when 'a maximum torque value that can be transmitted by the electric motor is lower than an initial torque value transmitted to the wheels by a heat engine just before the start of the gear change phase, a friction clutch is progressively disengaged during of a period of time until the torque transmitted to the wheels by the heat engine reaches a reduced torque value which is substantially equal to the maximum torque value that can be transmitted by the electric motor, the friction clutch is gradually engaged for a period of time until the torque transmitted to the wheels by the heat engine changes from the reduced torque value to the initial torque value, and the engine electrical transmits no torque during each time period.

[Document brevet 1] JP 2019-55771 A[Patent Document 1] JP 2019-55771 A

Problème techniqueTechnical problem

Cependant, dans JP 2019-55771 A, lorsqu'une valeur de couple maximale pouvant être transmise par le moteur électrique est inférieure à une valeur de couple initiale transmise aux roues par un moteur thermique juste avant le début de la phase de changement de rapport, il existe une période de temps au cours de laquelle le moteur électrique ne transmet aucun couple. Au cours de cette période, un embrayage à friction est désengagé ou engagé plus lentement qu’au cours d’une période au cours de laquelle le moteur électrique transmet du couple, et achever le changement de vitesse prend donc du temps, et le conducteur peut percevoir une sensation de retard pendant le changement de vitesse.However, in JP 2019-55771 A, when a maximum torque value that can be transmitted by the electric motor is lower than an initial torque value transmitted to the wheels by a heat engine just before the start of the gear change phase, there is a period of time during which the electric motor does not transmit any torque. During this period, a friction clutch is disengaged or engaged slower than during a period in which the electric motor is transmitting torque, and therefore completing the shift takes time, and the driver can perceive a feeling of delay when changing gears.

Ainsi, un objectif de la présente invention est de proposer un dispositif de commande de transmission automatique qui puisse réduire une sensation de retard perçue par le conducteur pendant un changement de vitesse.Thus, an object of the present invention is to provide an automatic transmission control device which can reduce a feeling of delay perceived by the driver during a gear change.

The automatic transmission control device may also include the following features, taken individually or in combination:
- The predetermined tolerance period is a period of time during which a total torque to be transmitted to the drive shaft, or the clutch torque, is less than or equal to a torque which is greater than a maximum output torque of the electric motor by a predetermined amount, during each of a clutch release process and a clutch connection process during the shift period, and
- The control unit, during the predetermined tolerance period of at least one of the clutch release process and the clutch connection process, increases the operating speed of the clutch and allows the torque assist from being provided by the electric motor as a function of the change in clutch torque in response to increasing operating speed.
