Abstract: A vehicle braking control apparatus includes an obstacle detection unit configured to detect an obstacle ahead of a vehicle, and to detect a distance to the obstacle from the vehicle, and a relative speed of the obstacle with respect to the vehicle; an electronic control unit configured to generate a braking force of the vehicle automatically based on the distance and the relative speed, and to weaken the braking force when a value subtracting a deceleration amount of a vehicle speed of the vehicle since a start of generating the braking force, from a predetermined upper-limit deceleration amount is less than or equal to a predetermined threshold. The upper-limit deceleration amount is set to increase while an elapsed time increases since the start of generating the braking force, at least after a predetermined first time has passed since the start of generating the braking force.

Abstract: A collision avoidance device includes a collision avoidance executor, a determiner, and a collision avoidance controller, for example. The collision avoidance executor can execute a collision avoidance function for a vehicle to avoid collision with an object to be avoided. The determiner determines, based on an operation of an accelerator pedal by a driver, whether the driver has an intention of acceleration. The collision avoidance controller inhibits execution of the collision avoidance function when the driver is determined to have the intention of acceleration. The determiner further determines, based on the operation of the accelerator pedal, whether the driver has an intention of cancelation of the collision avoidance function. The collision avoidance controller ends the execution of the collision avoidance function when the driver is determined to have the intention of cancelation during the execution of the collision avoidance function.

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.

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.
