Engine torque assisting device and torque assisting method using ISG

摘要

The present disclosure aims to determine the engine torque using the ISG so as to increase the fuel consumption. According to one embodiment of the present disclosure, an engine torque assist device is provided for assisting engine torque with ISG. An engine torque assisting device according to an embodiment includes an ISG control unit, a unit that calculates an accelerator opening change amount based on a signal indicating an accelerator opening degree from an accelerator opening degree sensor, a driver from an engine control unit And means for calculating a driver required torque change amount based on a signal indicating the requested torque. The ISG control section calculates the ISG control value when (i) the condition 1 the accelerator opening change amount, or (ii) the threshold 2 the driver demanded torque change amount and the threshold 3 the driver requested torque is satisfied, It is configured to generate ISG assist torque using ISG.
