Patent ID: 8790218

Claim:
A vehicle control system, which is applied to a vehicle comprising a fluid transmission mechanism, which is provided with a lockup clutch configured to directly connect an input member and an output member transmitting torque therebetween through a fluid, and which is connected with an output side of an internal combustion engine, and an auxiliary device, which is connected with the internal combustion engine to be driven by a torque of the internal combustion engine, and which is configured to stop a delivery of fuel to the internal combustion engine while increasing a speed change ratio of a transmission thereby increasing a speed of the internal combustion engine in case the vehicle is decelerated while engaging the lockup clutch, and to disengage the lockup clutch prior to restarting the delivery of fuel to the internal combustion engine, wherein the deceleration of the vehicle resulting from increasing the speed change ratio while engaging the lockup clutch is suppressed by lightening a load of the auxiliary device applied to the internal combustion engine; and the torque increased by restarting the delivery of fuel to the internal combustion engine is suppressed by increasing the load of the auxiliary device applied to the internal combustion.
