Abstract
Disclosed is a vehicle control apparatus which can prevent drivability from being deteriorated. An ECU is operative to set a reduction speed threshold value to determine a driver's braking intention on the basis of the correlation in the depression amount of an accelerator pedal, the depression amount of a brake pedal, and a travel state of a vehicle caused by the depression amounts of the accelerator pedal and the brake pedal. The ECU is further operative to change the reduction speed threshold value on the basis of the detected drive state to compare the travel state calculated on the basis of the detected drive state with the changed reduction speed threshold value to determine the driver's braking intention, thereby making it possible to determine the driver's braking intention without detecting the operation amount of a driver and to accurately estimate the driver's braking intention. This makes it possible to change the reduction control between executed and not executed, and to improve the drivability.
