Abstract
In a vehicle travel controlling apparatus including an automatic travel controlling ECU that controls a vehicle in a predetermined travel state by cooperation control of a vehicle driving amount and a vehicle braking amount, the automatic travel controlling ECU is provided with an automatic travel termination controlling unit. The automatic travel termination controlling unit obtains a brake fluid pressure during the cooperation control according to the vehicle driving amount during the cooperation control and a gradient of a road surface on which a vehicle is travelling. When the brake fluid pressure corresponding to a braking operation of a driver is more than the brake fluid pressure during the cooperation control, the automatic travel termination controlling unit terminates the cooperation control to switch operation to a braking operation according to the brake fluid pressure corresponding to the braking operation.
