Abstract
Before the termination of the fuel-cut control, the vehicle control system reduces a pumping loss by increasing an air intake and a load torque of an auxiliary device thereby preventing the vehicle to be decelerated excessively, and after the termination of the fuel-cut control, the vehicle control system increases the load torque of the auxiliary device thereby preventing the vehicle to be accelerated abruptly. Therefore, the vehicle speed will not be lowered unnecessarily before the termination of the fuel-cut control so that an execution time of the fuel-cut control can be extended. Moreover, driving comfort can be improved by thus reducing a change in acceleration.
