Assumption torque setting device, automatic transmission controller, and method for learning internal combustion engine delay model
Abstract:
An assumption torque setting device for an engine that executes a torque reduction process during gear shifting. The device sets a torque assumed to be output by the engine and based on a target torque from which an amount corresponding to the torque reduction process is excluded as an assumption torque during the gear shifting. The device includes an assumption model torque calculation unit which calculates an assumption model torque from the target torque from which an amount corresponding to the torque reduction process is excluded based on an internal combustion engine delay model. An assumption torque calculation unit calculates before torque reduction is performed an assumption torque based on an engine operation state and calculates when the torque reduction is being performed an assumption torque based on the assumption model torque and an assumption torque calculated from the engine operation state.
