    摘要： A method for controlling a downstream clutch in a vehicle during an upstream torque disturbance includes slipping a downstream clutch by reducing the downstream clutch pressure, varying the downstream clutch pressure to a target threshold to control the slip of the downstream clutch, increasing the downstream clutch pressure to engage the downstream clutch. A vehicle includes a first prime mover, a second prime mover connected to the first prime mover using an upstream clutch, a transmission connected to the second prime mover using a downstream clutch, and a controller connected to the first and second prime movers and the upstream and downstream clutches. The controller is configured to (i) slip the downstream clutch by reducing the pressure, (ii) vary the downstream clutch pressure to a target threshold to control the slip, and (iii) increase the downstream clutch pressure to engage the clutch.

    摘要： A torque-based clutch engagement controller for achieving smooth friction clutch engagement in a multiple-ratio transmission for an automotive vehicle driveline comprising a torque measuring circuit that determines torque inputs for the controller as a function of measured engine torque and turbine acceleration, means for determining the torque commanded by the vehicle operator as a function of engine throttle position, means for comparing the desired torque commanded by the operator to the input torque values, and means for converting the torque values to a pressure value as a function of the difference between the desired torque and the input torque whereby the pressure developed by the system applies a friction clutch so that engagement of the clutch occurs rapidly with optimum smoothness.
