Latest Patents

One of Haruki Sato's latest patents is a shift control apparatus for automatic transmission. This invention involves a shift controller that manages a downshift to a low shift speed, which is spaced apart from a high shift speed by two or more steps. The process includes releasing first and second shift release elements, engaging a first shift engagement element, and finally engaging a second shift engagement element. This method allows for revving up the input rotation at maximum engine performance, thereby reducing the time required for shifting. Additionally, the feedback control of the torque capacity of the second shift release element minimizes torque fluctuations at the intermediate shift speed, effectively avoiding uncomfortable shift shocks.

Another notable patent by Sato is also a shift control apparatus for automatic transmission. This invention focuses on disconnecting and connecting respective pairs of friction engagement elements during a downshift to a speed that is spaced apart by two or more steps. The shift controller regulates the hydraulic pressure of a second shift release element through feedback control. As the torque capacity of the second shift release element increases, the torque capacity of the first shift engagement element is also adjusted to ensure it is sufficiently higher than the change in the torque capacity of the second shift release element. This innovation effectively suppresses the generation of shift shocks, ensuring smoother transitions during gear changes.
