  • Patent number: 10166953
    Abstract: When a P lock state is set on the basis of a predetermined request signal for setting the P lock state, a P position indicator lamp (62) is turned on or off on the basis of the status of power supplied to the vehicle (10). For example, when the P lock state is set, the P position indicator lamp (62) is turned off when the power status is an ALL-OFF status where a combination meter (56), or the like, is not turned on or is raised to an ACC-ON status; whereas, when the P lock state is set, the P position indicator lamp (62) is turned on when the power status is an IG-ON status, when the power status is changed from the IG-ON status during vehicle driving to the ACC-ON status, or within a predetermined period of time from when the power status is changed from the IG-ON status to the ALL-OFF status.

  • Patent number: 9611932
    Abstract: When initial drive control for an actuator driving a shift switch mechanism is completed, a P-ECU determines whether an IG signal is received. In the case where the P-ECU has not received the IG signal at the time when the initial drive control is completed, the P-ECU temporarily keeps the actuator in a state where the initial drive control is completed. In the case where the P-ECU receives the IG signal in the period from completion of the initial drive control to the time when a predetermined time T2 has elapsed since completion of the initial drive control, the P-ECU executes P wall press control when the P-ECU receives the IG signal.

  • Patent number: 8777811
    Abstract: A vehicular shift control device is provided that controls the input rotational speed of a geared transmission by adjusting the rotational speed of a drive source at downshift of the geared transmission. The greater the deceleration of the vehicle, the smaller is set the change gradient of the input rotational speed of the geared transmission. Therefore, even if the decrease rate of the post-shifting synchronization rotational speed is great, the incident angle ? of the input rotational speed of the geared transmission relative to the post-shifting synchronization rotational speed is maintained as a large angle. Even when the deceleration of the vehicle during downshift is great, the downshift is smoothly executed without producing an excessive synchronization shock.

  • Patent number: 8296026
    Abstract: In a control apparatus for a powertrain that includes an automatic transmission, occurrence of slip in a one-way clutch is determined when one gear is formed if a first rotation member and a second rotation member of the one-way clutch rotate relatively. If slip in the one-way clutch is detected, it is determined whether the rotational speed difference between the first rotation member and the second rotation member has increased. If the rotational speed difference between the first rotation member and the second rotation member has increased when slip is detected in the one-way clutch, a control is executed to engage a predetermined frictional engagement element.

  • Patent number: 7549946
    Abstract: The invention relates to a shift control apparatus for an automatic transmission, that executes a torque reduction control when the transmission executes a second downshift in response to a second downshift determination made during first downshift. The shift control apparatus includes a multiple shift execution unit that starts the second downshift operation in response to the second downshift determination, and a torque reduction control execution unit that executes a torque reduction control when the rotational speed of the input member is increased to at least a predetermined first determination speed, which is determined in accordance with a shift ratio of a gear stage after the second downshift operation, after the second downshift starts. This allows the rotational speed of the input shaft to be quickly changed to the appropriate synchronous rotational speed. Thus, the desired driving force is provided upon completion of the second downshift without overspeeding the engine.

  • Patent number: 7544149
    Abstract: The invention relates to a shift control apparatus for an automatic transmission that executes a torque reduction control when the transmission downshifts in response to a downshift determination made during an upshift. The shift control apparatus includes a multiple shift execution unit that starts the downshift in response to the downshift determination, and a torque reduction control execution unit that determines whether the rotational speed of the input member is at least a control start-up rotational speed, after the downshift operation starts, and executes a torque reduction control of the power source when the rotational speed of the input member is increased to at least the control start-up rotational speed. This allows the rotational speed of the input shaft to be quickly changed to the appropriate synchronous rotational speed. Thus, the desired driving force is provided upon completion of the downshift without overspeeding the engine.
