Abstract:
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.
