Description
この目的を達成するために、この発明は、駆動力源からトルクが伝達される入力部材と駆動輪に対してトルクを出力する出力部材との間に無段変速機構と伝動機構とが並列に設けられ、供給される油圧に応じたトルクを前記入力部材から前記伝動機構に伝達する摩擦係合機構と、前記入力部材から前記出力部材に向けたトルクの伝達方向で前記摩擦係合機構よりも下流側に配列され、かつ供給される油圧に基づいて前記伝動機構を前記入力部材と前記出力部材との間でトルク伝達可能な状態にする噛み合い式係合機構とが設けられている車両用変速機の制御装置において、前記摩擦係合機構および噛み合い式係合機構が共に開放していて前記伝動機構がトルクを伝達できない状態から前記噛み合い式係合機構を係合させて前記伝動機構を前記出力部材にトルクを伝達できる状態にする際に、前記摩擦係合機構のトルク容量を前記伝動機構が回転するトルク容量に増大させた後、前記噛み合い式係合機構が係合し始めるように、前記摩擦係合機構への油圧の供給の開始以後に前記噛み合い式係合機構を係合させるための油圧供給指令を開始するように構成されていることを特徴とするものである。
To this end, the present invention comprises a continuously variable transmission mechanism and the transfer movement mechanism parallel between an output member for outputting the torque to the input member and the drive wheel torque is transmitted from the driving force source provided, the frictional engagement mechanism for transfer reaches a torque corresponding to the hydraulic from the input member to the transmission mechanism is supplied, from the frictional engagement mechanism from the input member in direction of transmission of torque toward the output member also been sequence downstream, a meshing type engagement mechanism front Symbol transmission mechanism into a state capable of transmitting torque between the output member and the input member based on the hydraulic pressure provided to be either one supply In the control device for a vehicle transmission, the transmission is performed by engaging the meshing engagement mechanism from a state where both the friction engagement mechanism and the meshing engagement mechanism are open and the transmission mechanism cannot transmit torque. Mechanism When ready to transmit torque to the force member, after the torque capacity of the friction engagement mechanism front Symbol transmission mechanism increased in torque capacity to rotate, such that the meshing type engagement mechanism begin to engage , and it is characterized in that it consists to begin hydraulic supply command for engaging the meshing type engagement mechanism since the start of the supply of hydraulic pressure to the frictional engagement mechanism.
あるいは、この発明における前記伝動機構が回転する程度のトルク容量を設定する油圧は、その伝動機構の回転数と油温との少なくともいずれか一方に基づいて設定されてよい。
Alternatively, hydraulic pressure to set the degree of torque capacity before Kiden kinematic mechanism to rotate in the invention may be set based on at least one of the rotational speed and the oil temperature of the transmission mechanism.
この発明によれば、前記伝動機構の入力側に配置されている摩擦係合機構および出力側に設けられている噛み合い式係合機構が開放状態になっていてその伝動機構がトルクを伝達していない状態から噛み合い式係合機構を係合させて出力部材にトルクを伝達できる状態にする場合、その噛み合い式係合機構が係合状態に切り替わることに遅れることなく、摩擦係合機構がある程度のトルク容量を持つように制御されて伝動機構が回転させられる。したがって、噛み合い式係合機構が取り付けられている出力部材が停止していてもその噛み合い歯同士の位相が一致してぶつかり合う状態が解消され、噛み合い式係合機構を確実に、またスムースに係合状態に切り替えることができる。また、伝動機構をこのように回転させるトルクは摩擦係合機構によって伝達され、そのトルクは伝動機構が回転する程度の小さいトルクに設定でき、かつそのトルク容量を上回る負荷が掛かった場合には摩擦係合機構に滑りが生じてそれ以上のトルクが伝動機構や出力部材に掛からない。そのため、噛み合い式係合機構が係合して入力部材から出力部材に伝動機構を介してトルクが伝達されるとしても、過大なショックや摩耗が生じることを防止もしくは抑制することができる。
According to this invention, the friction engagement mechanism disposed on the input side of the transmission mechanism and the meshing engagement mechanism provided on the output side are in an open state, and the transmission mechanism transmits torque. In the case where the meshing engagement mechanism is engaged from the state where the meshing engagement mechanism is engaged so that torque can be transmitted to the output member, the frictional engagement mechanism has a certain degree of delay without delaying the switching of the meshing engagement mechanism to the engagement state. The transmission mechanism is rotated so as to have a torque capacity. Therefore, even if the output member to which the meshing engagement mechanism is attached is stopped, the state where the meshing teeth coincide with each other in phase is eliminated, and the meshing engagement mechanism is reliably and smoothly engaged. Can be switched to a combined state. Further, the torque for rotating the transmission mechanism in this way is transmitted by the friction engagement mechanism, and the torque can be set to a torque that is small enough to rotate the transmission mechanism, and if a load exceeding the torque capacity is applied, the friction is applied. sliding engagement mechanisms occur more torque is not applied to the transmission mechanism and the output member. Therefore, even if the torque is transmitted through meshing type engagement mechanism a transmission mechanism is engaged with the input member or et output member, it is possible to prevent or suppress the excessive shock and wear occurs.
また、前記噛み合い式係合機構を係合させるのに当たって摩擦係合機構に供給する油圧を、伝動機構の回転数や油温に基づいて設定することにより、伝動機構を回転させることのできる程度の小さいトルク容量を正確に設定でき、また過大なショックが発生したり、摩擦係合機構に過剰な滑りが生じたりすることを防止もしくは抑制することができる。 Further, the hydraulic pressure supplied to the friction engagement mechanism against to engage the front Symbol meshing type engagement mechanism, by setting on the basis of the rotational speed and the oil temperature of the transmission mechanism, the extent capable of rotating the transmission mechanism A small torque capacity can be accurately set, and an excessive shock can be prevented or an excessive slip can be prevented from occurring in the friction engagement mechanism.
