  • Publication number: 20180015928
    Abstract: An automatic transmission control device implements a downshift by disengagement of a clutch that is engaged in a gear position before the downshift. It is determined whether an engine state is in a predetermined region in which a change of an engine torque per a change of an accelerator pedal opening is smaller than that in another region, and the engine torque is within a predetermined range, and an engine rotational speed is within a predetermined range. It is determined whether an operating state is in a predetermined state of accelerator operation in which the accelerator pedal opening is larger than a predetermined value, and an accelerator pedal opening change rate has an absolute value smaller than a predetermined value. The downshift is inhibited in response to determination that the engine state is in the predetermined region and the operating state is in the predetermined state of accelerator operation.

If the steering torque has an absolute value greater than a threshold value when the vehicle is in a straight-line traveling state, the controller sets the correction value such that the absolute value of the steering torque is reduced. If the steering torque has an absolute value less than the threshold value when the vehicle is in a straight-line traveling state, the controller sets the correction value such that the absolute value of the assist command value is reduced.

A lower-link oil passage has a one-end-side opening structured to open to a pin-boss-facing surface of the lower link facing the outer circumferential surface of the pin boss part of the upper link and its other-end-side opening structured to open to a crankpin bearing surface. The lower-link oil passage is configured to point, at a prescribed crankangle, to a specified end edge of end edges of the other-end-side opening of the pin-boss oil passage, the specified end edge facing one end side of the upper link.

  • Patent number: 9856810
    Abstract: A fuel cut during deceleration is executed at time point t1. An oxygen storage amount (rOS) which increases with this fuel cut is estimated based on an exhaust air-fuel ratio and an intake air quantity. When the oxygen storage amount (rOS) reaches a threshold value (at time point t2), a target compression ratio (tCR) is corrected to become lower than a basic target compression ratio (tCR). Although a fuel recovery is executed at time point t4, a combustion temperature is lowered because of the lowering of the mechanical compression ratio, so that a production of NOx in a combustion chamber is suppressed. Therefore, worsening of NOx is suppressed even if the oxygen storage amount (rOS) of exhaust-emission purification catalyst (4) is excessive.

  • Patent number: 9856976
    Abstract: A lock-up clutch control device is provided for a vehicle having a torque converter with a lock-up clutch disposed between an engine and a continuously variable transmission such that the occurrence of shocks during lock-up engagement is suppressed. The vehicle lock-up clutch control device is provided with a control unit that controls the lock-up capacity based on an engine torque signal when engaging the lock-up clutch. The control unit uses a predictive engine torque as the engine torque signal for use in the lock-up capacity control. The predictive engine torque is calculated based on an engine torque air response delay and a hydraulic response delay in the lock-up differential pressure and is faster in response than the actual engine torque.
