1. A vehicle cruise control apparatus comprising:
- a vehicle speed adjusting device that adjusts a vehicle speed to a set target vehicle speed;
a brake operation detecting device that detects that a brake pedal is depressed by a driver;
an inclination detecting device that detects an inclination of a road surface on which the vehicle is traveling;
a vehicle speed detecting device that detects the vehicle speed; and
a first controller that calculates a target driving force so that the vehicle speed becomes equal to the set target vehicle speed and controls the vehicle speed adjusting device based on the target driving force, whereinif the brake pedal is depressed by the driver, the first controller controls the vehicle speed adjusting device based on a driving force that maintains the vehicle in a stopped condition as the target driving force, whereinthe first controller calculates a driving force that makes the detected vehicle speed equal to the target vehicle speed; and
the target driving force includes an inclination target driving force that maintains the vehicle in a stopped condition at the detected inclination, and a feedback target driving force determined by subtracting the inclination target driving force from the calculated driving force.
