A control system for a vehicle includes a powertrain comprising a prime mover and a driveline. The control system selectively controls the driveline to assume a first state in which a transmission of the driveline is substantially fully connected to the prime mover and a second state in which when the vehicle is stationary the transmission is at least partially disconnected or decoupled from the prime mover to reduce a torque loading on the prime mover. The control system controls the driveline to assume the second state when the vehicle is held stationary by a brake in response to actuation of a driver operable brake control. Upon release of the brake control, the control system verifies that a first portion of a powertrain of the vehicle is rotating at a speed exceeding a prescribed threshold and commands the driveline to assume the first state before permitting release of the brake.
