Abstract: When a transmission controller issues a control command, such as pressure to control clutch torque, the response may be delayed due to dynamic properties of the control system. These properties can be modeled using a dynamic response model. One potential model is a combination of a pure time delay and a first order distributed delay. Control methods may be improved in several ways by accounting for the dynamic response. First, the dynamic response model may be used to improve adaptation of a transfer function between the commanded control signal and the clutch torque. Second, the command may be adjusted based on the dynamic response model. Both the pure time delay and the time constant of the first order distributed delay may be functions of operating conditions such as temperature.

Abstract: While a vehicle is decelerating starting at a braking start time, start-off pre-shifting starts when speed falls to a predetermined speed. At a vehicle stoppage time, an idle stop permission flag is not set to on if start-off pre-shifting is incomplete, even if idle stop permission conditions have been met. The idle stop permission flag is set to on when start-off pre-shifting is completed, and an idle stop flag is set to on and the engine stopped when engine rotational speed falls below a set speed. The engine is restarted in response to braking being released, and the idle stop flag is set to off and the idle stop control ended when the engine rotational speed reaches or exceeds a set speed. The restarting of the engine causes an engine-driven oil pump to dispense oil to be used as a medium to manifest an automatic clutch command hydraulic pressure.
