1. A vehicle control method comprising:
controlling a drive torque of a drive source that drives a vehicle using a drive source controller;
detecting a stroke amount of a brake pedal using a stroke sensor;
controlling automatic braking when a required braking torque is generated regardless of a brake pedal operation by a driver using a braking force controller;
outputting an ON signal using a brake switch when the brake pedal is depressed due to the brake pedal operation by the driver and when an operation of the automatic braking; and
calculating a brake required torque and a drive source required torque necessary for constant speed travel or travel to follow a preceding vehicle;
outputting the drive source required torque to the drive source controller;
outputting the brake required torque to the braking force controller to perform cruise control; and
prohibiting acceptance of the drive source required torque when the automatic braking control is activated during the cruise control, or not outputting the drive source required torque to the drive source controller when the automatic braking control is activated during the cruise control.
