By this means, a current status of a management target document that changes every moment can be updated and managed in detail in real time. In one example, negative torque of an electric machine is adjusted to mimic negative torque of an engine during engine braking so that the vehicle may transition from regenerative braking to engine braking in a seamless manner.
