Abstract: In a vehicle collision determination apparatus, a position calculation unit calculates a trajectory of a target that is a movement trajectory of the target, and calculates an entrainment trajectory of the vehicle that is a movement trajectory of the vehicle during a turn, and calculate a position of collision where a collision is likely to occur between the vehicle and the target based on the trajectory of the target and the entrainment trajectory of the vehicle.

In response to the time to collision being equal to or less than a predefined determination threshold, a risk determination unit determines that there is a risk of collision between the vehicle and the target.
