Abstract
A vehicle cruise control apparatus includes a vehicle speed adjusting device that adjusts a vehicle speed to a set target vehicle speed, a brake operation detecting device that detects brake operation performed by a driver, and a first controller that controls the vehicle speed adjusting device based on a target driving force that maintains a vehicle in a stopped condition, when the brake operation performed by the driver is detected.
Claims13
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, wherein
- if 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, wherein
- the 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.
