摘要: A torque converter lockup capacity control device is configured to conduct coast-time lockup control during coast-running in order to prevent engine stall, shock from occurring in the output shaft of a transmission due to lockup when a driver releases an acceleration pedal and the running condition switches from a drive running condition to a coast-running condition. Torque converter lockup occurs because the engine output torque drops from a time on when the throttle opening degree becomes zero. Thus, during a period from the time on until fuel cut-in at time, the lockup capacity is lowered to a minimum capacity corresponding to a standby pressure and lockup is avoided. The lockup capacity is raised to a larger value from the predetermined time on, and ordinary coast-time lockup control is executed.

摘要: A device and method that suppresses delay in response to gear-shifting in upshifting during control for preventing over-rotation. An engine torque control part controls the torque of the engine based on a driver request for driving force, a rotation velocity sensor detects the rotation velocity of the engine, and an over-rotation preventing part suppresses the controlled torque based on the velocity and prevents over-rotation of the engine. An over-rotation prevention releasing part releases suppression of the torque based on the rotation velocity lowered due to upshifting of the automatic transmission, and an engine torque increasing rate regulating part regulates the increasing rate of the torque when said suppression of the torque is released and the torque is increased.

摘要: An engine torque control device is configured to reduce shift shock during a downshift with an automatic transmission. During a downshift with an automatic transmission having a stepped shift mechanism, when the engine output (torque) is increased so as to bring it closer to being synchronized to the post-downshift engine speed, and then the torque is reduced sharply enough to maintain the synchronizing speed, and when synchronizing control is concluded so that the torque is sharply reduced to the driver's required torque in a state in which the accelerator is released, the throttle opening is reduced while any extra torque resulting from a reduction lag in the intake air quantity is cancelled out by retarding the ignition timing, thereby sufficiently lessening shift shock.
