Abstract

In a driving support apparatus mounted in an own vehicle, an obstacle detector detects an obstacle present on a front side in a traveling lane. A rear vehicle detector detects a rear vehicle. An operation controller determines an avoiding operation by one of a lane change operation for changing to a lane adjacent to the traveling lane, a steering operation for steering in the traveling lane, and a braking operation for applying a brake in the traveling lane and controlling the own vehicle to perform the avoiding operation to avoid the obstacle. A collision estimator estimates presence or absence of a collision between the rear vehicle and the obstacle in a case in which the own vehicle performs the avoiding operation by one of the lane change operation and the steering operation. The operation controller determines the avoiding operation based on the estimated presence or absence of the collision.

Dependent claims

A driving support apparatus for a vehicle, comprising:

a non-transitory memory storing one or more computer programs;
and
a processor executing the one or more computer programs to:
detect an obstacle present on a front side in a traveling lane in which an own vehicle travels with respect to the own vehicle, the own vehicle being a vehicle carrying the driving support apparatus;
detect a rear vehicle traveling on a rear side in the traveling lane with respect to the own vehicle;
determine an avoiding operation by one of a lane change operation for changing the traveling lane to a lane adjacent to the traveling lane, a steering operation for steering in the traveling lane, and a braking operation for applying a brake in the traveling lane and controlling the own vehicle to perform the avoiding operation to avoid the obstacle;
estimate a presence or absence of a collision between the rear vehicle and the obstacle in a case in which the own vehicle performs the avoiding operation by one of the lane change operation and the steering operation to avoid the obstacle;
and
determining the avoiding operation of the own vehicle based on the estimated presence or absence of the collision between the rear vehicle and the obstacle.

6 more elements

A computer-implemented method for performing driving support by an own vehicle, the method comprising:

detecting an obstacle present on a front side of the own vehicle in a traveling lane in which the own vehicle travels;
detecting a rear vehicle traveling on a rear side in the traveling lane with respect to the own vehicle;
determining an avoiding operation using one of a lane change operation for changing the traveling lane to a lane adjacent to the traveling lane, a steering operation for steering in the traveling lane, and a braking operation for applying a brake in the traveling lane and controlling the own vehicle to perform the avoiding operation to avoid the obstacle;
predicting whether the rear vehicle and the obstacle will collide in a case in which the own vehicle performs the avoiding operation using one of the lane change operation and the steering operation to avoid the obstacle;
and
determining the avoiding operation of the own vehicle based on predicting whether the rear vehicle and the obstacle will collide.
