1. A driving support apparatus comprising:
a sensor configured to acquire sensor information that is used to acquire a distance between a vehicle and an object; and
a controller configured to execute a driving support control using a first distance representing a distance between the vehicle and a predetermined target object as a control distance, the first distance being acquired by applying a first recognition method to the sensor information,
wherein, the first recognition method has a characteristic that a recognition reliability of the target object increases as an acquisition time of the first distance increases,
wherein,
the controller is further configured to use an extrapolation distance representing the vehicle and the target object as the control distance, when the first distance can no longer be acquired and the acquisition time is equal to or longer than a predetermined threshold time, the extrapolation distance being estimated based on an acquired distance representing the first distance which was acquired and a speed of the vehicle
wherein,
the controller is further configured to:
recognize the target object and acquire a second distance between the vehicle and the target object, by applying, to the sensor information, a second recognition method of which a distance accuracy is lower than the distance accuracy of the first recognition method; and
in a case where the first distance can no longer be acquired and the acquisition time of the first distance is shorter than the threshold time, use the second distance as the control distance when a first approaching state and a second approaching state coincide with each other,
wherein,
the first approaching state, which is specified based on a traveling direction of the vehicle, represents whether the target object recognized using the second recognition method is approaching to the vehicle or going away from the vehicle,
the second approaching state, which is specified based on the second distance, represents whether the target object recognized using the second recognition method is approaching to the vehicle or going away from the vehicle.
