CONTROL DEVICE FOR VEHICLES

摘要

Provided is a control device for vehicles, capable of improving engine fuel consumption during ACC (Adaptive Cruise Control). A first torque calculation unit calculates a first target engine torque having the smallest fuel consumption rate among target engine torques corresponding to engine speed. A first vehicle speed control unit engages a clutch inside a transmission and operates the engine at the first target engine torque calculated by the first torque calculation unit, if actual vehicle speed has reached a first lower limit vehicle speed that is smaller than a target vehicle speed, and stops the engine and releases the clutch if the actual vehicle speed has reached a first upper limit vehicle speed greater than the target vehicle speed.
