Abstract

A driving support apparatus for a vehicle is provided. The apparatus causes an alarm unit to issue an alarm based on a lane marking of an own lane in which an own vehicle runs. The apparatus includes a leading vehicle detection section that determines a leading vehicle running in the own lane, a crossing over determination section that determines whether or not the leading vehicle has crossed over the lane marking present at an opposite side of the target, when a target is present at a left side or a right side of the leading vehicle in the own lane, and an alarm inhibition section that inhibits the alarm based on a result of the determination whether or not the leading vehicle has crossed over the lane marking present at the opposite side of the target.

Claims

1. A driving support apparatus for a vehicle, the apparatus causing an alarm unit to issue an alarm based on a lane marking of an own lane in which an own vehicle runs and comprising:

a leading vehicle detection section that determines a leading vehicle running in the own lane;

a moving obstacle detection section that determines a moving obstacle around the own vehicle;

an available travel area size difference determination section that detects a difference between a first available size of a certain travel area ahead of the own vehicle when the leading vehicle passed through, and a second available size of the certain travel area when the own vehicle is about to pass through;

an allowance determination section that determines whether or not the own vehicle is allowed to cross over the lane marking, based on the difference between the first available size and the second available size and further based on a moving speed and a moving direction of the obstacle determined by the moving obstacle detection section; and

an alarm inhibition section that inhibits the alarm when the allowance determination section determines that the own vehicle is allowed to cross over the lane marking.

2. The driving support apparatus according to claim 1, wherein

the allowance determination section determines whether or not the own vehicle is allowed to cross over the lane marking, based on the obstacle present ahead of the own vehicle or a situation of a leading vehicle.

3. The driving support apparatus according to claim 1, wherein

the lane marking includes a virtual lane.
