  • Patent number: 10344850
    Abstract: A shift control apparatus of an automatic transmission includes: an input detecting unit configured to detect a real rotational speed of the input shaft; an output detecting unit configured to detect a real rotational speed of the output shaft; an estimating unit configured to estimate an estimated rotational speed of the input shaft, which corresponds to a shift request, by multiplying the real rotational speed of the output shaft by a target gear ratio; and a control unit configured to control the rotation of the input shaft based on a detection result from the input detecting unit. The control unit controls the rotation of the input shaft such that an upper-limiting rotational speed of a variation in real rotational speed of the input shaft is lower than the estimated rotational speed.
    Type: Grant

  • Patent number: 9636987
    Abstract: A hybrid vehicle is provided in which in the neutral range or the parking range, power can be generated in a first power generation mode by engaging an odd-numbered position clutch so as to transmit a driving force of an engine to a motor/generator via a first input shaft, and power can be generated in a second power generation mode by engaging an even-numbered position clutch so as to transmit the driving force of the engine to the motor/generator via reversing means and the first input shaft. Therefore, according to the status of the odd-numbered position clutch and the even-numbered position clutch, by engaging either one thereof, it becomes possible to generate power in the first power generation mode or the second power generation mode, thus enabling power to be supplied without interruption.
