Abstract:
1. A vehicle comprising: an internal combustion engine; a torque output module that is connected to an output shaft of said internal combustion engine and a drive shaft connected to an axle via a gear mechanism, said torque output module outputting torque, while supplying and receiving electric power and mechanical power and outputting a torque as a reaction force to one of said output shaft and said drive shaft, to the other one of said output shaft and said drive shaft; an electric motor capable of supplying and receiving mechanical power to and from said drive shaft; an accumulator unit capable of supplying and receiving electric power to and from said torque output module and said electric motor; and a control module that, when a system stop instruction is issued in the middle of the operation of said internal combustion engine, controls said internal combustion engine and said torque output module in such a way that the output shaft of said internal combustion engine is stopped within a predetermined rotational position range, controls said electric motor in such a way that the sum of a cancelling torque that cancels the torque outputted as the reaction force to said drive shaft in response to the output of the torque from said torque output module to the output shaft of said internal combustion engine and a pressing torque necessary to press the engagement of the gears in said gear mechanism toward one side is outputted from said electric motor, controls said electric motor in such a way that the torque from said electric motor gradually decreases at least after said internal combustion engine has stopped, and stops the system when the torque outputted from said electric motor reaches a predetermined torque.
