  • Patent number: 10495660
    Abstract: An actual slip amount (S) of a torque converter is calculated by subtracting an actual input shaft rotational speed (Nr) of an automatic transmission from an engine rotational speed (Ne), which is the rotational speed of a crankshaft. Then, an engine rotational speed for display (Nd) is calculated by adding a slip amount adjusted for display (Sp), which is obtained by applying a predetermined correction process to the actual slip amount (S) to the actual input shaft rotational speed (Nr). The above described correction process may be a first-order-lag filter processing, for example. Thus, even when the actual slip amount (S) temporarily increases or decreases, a temporary increase or decrease in the engine rotational speed for display (Nd) may be suppressed. In other words, fluctuation or variation in the engine rotational speed for display (Nd) is suppressed.

  • Patent number: 10066741
    Abstract: A hydraulic control system for an automatic transmission with a torque converter includes two regulator valves controlled by a single variable force solenoid (VFS). A bypass clutch regulator valve increases the pressure to a bypass clutch apply chamber as the VFS pressure increases. A converter charge regulator valve decreases the pressure in a converter charge circuit as the VFS pressure increases. The converter charge circuit is in series with a lubrication circuit. An orifice restricts the flow through these circuits such that they can be supplied from the line pressure circuit rather than a lower priority circuit. In one embodiment, an on/off solenoid opens a flow control valve to bypass the orifice when additional flow is required. In another embodiment, an electric pump supplements the flow in these circuits when required. This later embodiment includes a switch valve such that the electric pump also supports stop/start operation.
