Driving support apparatus

A driving support apparatus comprising:

• a determinator configured to determine a collision probability between a host vehicle and an obstacle;
• and
• a braking controller programmed to perform (i) a braking control for applying a braking force for avoiding a collision between the host vehicle and the obstacle to the host vehicle, and (ii) a preliminary braking control for applying to the host vehicle before the braking control a braking force for allowing at least one of a driver of the host vehicle and a driver of another vehicle that is around the host vehicle to recognize that the braking control is to be performed, on the basis of the collision probability, wherein
• said braking controller including:
• a braking force increaser configured to increase the braking force applied in the preliminary braking control in accordance with a brake operation if the brake operation is performed by the driver of the host vehicle during execution of the preliminary braking control;
• and
• if the braking force applied at an end time point of the preliminary braking control is greater than the braking force applied at a start time point of the braking control as a result of the increase in the braking force applied during the preliminary braking control, a braking force adjuster is configured to perform adjustment (i) in such a manner that a braking force adjustment applied in transferring from the preliminary braking control to the braking control is brought close to the braking force applied at the start time point of the braking control while having a change amount per unit time that is less than a predetermined value, or (ii) in such a manner that the braking force applied at the start time point of the braking control is adjusted to be greater than the braking force applied at the end time point of the preliminary braking control.
