Abstract: A collision avoidance ECU sets a model deceleration change amount to smaller value in a state in which it is difficult to reduce the speed of a host vehicle than in a state in which it is easy to reduce the speed of the host vehicle. The collision avoidance ECU calculates a first target value by multiplying the model deceleration change amount by the elapsed time. The collision avoidance ECU obtains a subtraction value by subtracting the current reference relative deceleration from the first target value. Then, the collision avoidance ECU determines a target relative deceleration to be a greater value when the subtraction value is large than when the subtraction value is small, and carries out brake control so that the reference relative deceleration approaches the target relative deceleration.

Abstract: A collision avoidance ECU sets a target relative deceleration to a first target value when a brake control starting condition is satisfied, and carries out a first brake control for bringing a relative deceleration closer to the target relative deceleration. When a reference relative deceleration with reference to the relative deceleration at a first point in time has reached a specified relative deceleration, the collision avoidance ECU determines a greater value for a second target value when the amount of change in deceleration, which is the amount of change in the reference relative deceleration at the point in time, is small than when the amount of change in deceleration is large. The collision avoidance ECU then sets the target relative deceleration to the second target value, and carries out a second brake control for bringing the relative deceleration closer to the target relative deceleration.

Abstract: An ECU calculates: a free running distance, which is a distance that a vehicle can travel from a first time point at which a speed-reduction control is started to a second time point at which the relative deceleration begins to increase by the start of the speed-reduction control; an increase travel distance, which is a distance that the vehicle can travel from the second time point to a third time point at which the relative deceleration reaches the target relative deceleration; and a post-completion travel distance, which is a distance that the vehicle can travel from the third time point to a time point at which the relative speed is made equal to or less than the specified speed. The ECU obtains a speed reduction distance based on a result of adding up the free running distance, the increase travel distance, and the post-completion travel distance.
