Abstract
In a control apparatus for a vehicle, when a coast downshifting is performed in response to a downshifting command from a vehicle operator during braking operation under the fuel cut control, the braking force of the wheel brake is increased so as to increase the deceleration. This makes it possible to achieve a predetermined deceleration with a good response to the deceleration request of the vehicle operator represented by the downshifting command. The control apparatus is structured to decrease the braking force of the wheel brake such that the increase in the engine braking force is offset by the inertia caused by the rise in the engine speed resulting from downshifting upon the coast downshifting due to the vehicle speed increase. The control apparatus for the vehicle, thus, reduces the shock caused by the sharp increase in the engine braking force.
