1. A vehicle control device comprising:
- a vehicle speed obtaining unit that obtains a vehicle speed of a host vehicle;
an object distance obtaining unit that obtains a distance to an object ahead of the host vehicle;
a collision judgment unit that determines whether or not there is a risk of a collision between the object and the host vehicle, based on the obtained vehicle speed and the obtained distance to the object;
an avoidance judgment unit that, responsive to a determination by the collision judgment unit that there is a risk of a collision between the object and the host vehicle, determines whether the collision between the object and the host vehicle can be avoided through a steering operation based on whether or not there is an adjacent lane next to a lane in which the host vehicle is traveling; and
a braking control unit that executes braking control to decelerate the host vehicle responsive to a determination by the avoidance judgment unit that a collision between the object and the host vehicle cannot be avoided by a steering operation.

Abstract
An anti-collision control is provided under circumstances where it is determined that there is a risk of collision between a host vehicle and a preceding vehicle. The anti-collision control utilizes host vehicle information, preceding vehicle information, and surrounding road conditions to determine whether or not a collision with the preceding vehicle can be avoided through a steering operation. If avoidance is determined to be possible, then a shift-hold control is applied to the AT, whereas if avoidance is determined to be impossible, then a down-shift control is applied to the AT.

3. A vehicle control method comprising the steps of:
-
obtaining a vehicle speed of a host vehicle; obtaining a distance to an object ahead of the host vehicle; determining whether there is a risk of a collision between the object and the host vehicle based on the host vehicle speed and the distance to the object; responsive to a determination that there is a risk of a collision between the object and the host vehicle, determining whether the collision between the object and the host vehicle can be avoided through a steering operation based on whether there is an adjacent lane next to a lane in which the host vehicle is traveling; and controlling braking to decelerate the host vehicle responsive to a determination that a collision between the object and the host vehicle cannot be avoided by a steering operation. - View Dependent Claims (7, 8)

4. A computer-readable medium encoded with a program for causing a computer to execute:
-
a vehicle speed obtaining function that obtains a vehicle speed of a host vehicle; an object distance obtaining function that obtains a distance to an object ahead of the host vehicle; a collision judgment function that determines whether or not there is a risk of a collision between the object and the host vehicle based on the obtained vehicle speed and the obtained distance to the object; an avoidance judgment function that, responsive to a determination by the collision judgment function that there is a risk of a collision between the object and the host vehicle, determines whether or not the collision between the object and the host vehicle can be avoided through a steering operation based on whether there is an adjacent lane next to a lane in which the host vehicle is traveling; and a braking control function that controls braking to decelerate the host vehicle responsive to a determination that a collision between the object and the host vehicle cannot be avoided by a steering operation. - View Dependent Claims (9, 10)
