ABSTRACT:
This invention relates to a hybrid vehicle controlling device and method of using the device, in which an engine torque proportion (which is transmitted from an engine to a driving shaft) of a total sum of torque transmitted to the driving shaft is calculated. An allowed surge torque value, which is an upper limit of a surge torque allowed to the engine, is set to a larger value as the engine torque proportion is reduced. Then a predetermined parameter of the engine is changed so that the engine is controlled in a range in which the surge torque of the engine does not go beyond the allowed surge torque value.
