Abstract
Official abstract text for this publication.
A vehicle control device includes a drive source controller configured to control a drive source on the basis of a creep drive force set so that a vehicle does not slip down when being stopped on a gradient road, and a braking force calculator configured to calculate a braking force generated on the basis of a braking operation of a driver. The drive source controller reduces a drive force generated by the drive source when the braking force is larger than the creep drive force when the vehicle is stopped. The creep drive force is a force not smaller than a force balanced with a force acting in a slip-down direction of the vehicle at a minimum gradient at which a hill hold function is activated.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle control device, comprising: a drive source controller configured to control a drive source on the basis of a creep drive force set so that a vehicle does not slip down when being stopped on a gradient road; and a braking force calculator configured to calculate a braking force generated on the basis of a braking operation of a driver, wherein the drive source controller reduces a drive force generated by the drive source when the braking force is larger than the creep drive force when the vehicle is stopped, and wherein the creep drive force is a force not smaller than a force balanced with a force acting in a slip-down direction of the vehicle at a minimum gradient at which a hill hold function is activated. 2. A vehicle control method, comprising: controlling a drive source on the basis of a creep drive force set so that a vehicle does not slip down when being stopped on a gradient road; calculating a braking force generated on the basis of a braking operation of a driver; and reducing a drive force generated by the drive source when the braking force is larger than the creep drive force when the vehicle is stopped, wherein the creep drive force is a force not smaller than a force balanced with a force acting in a slip-down direction of the vehicle at a minimum gradient at which a hill hold function is activated. 3. A vehicle control device, comprising: drive source control means configured to control a drive source on the basis of a creep drive force set so that a vehicle does not slip down when being stopped on a gradient road; and braking force calculation means configured to calculate a braking force generated on the basis of a braking operation of a driver, wherein the drive source control means reduces a drive force generated by the drive source when the braking force is larger than the creep drive force when the vehicle is stopped, and wherein the creep drive force is a force not smaller than a force balanced with a force acting in a slip-down direction of the vehicle at a minimum gradient at which a hill hold function is activated.
