Classification: CPC B | IPC B

Claim 0:
1. A vehicle driving assist apparatus, comprising an electronic control unit which is configured to:
acquire (i) a collision index value which represents a magnitude of a collision of an own vehicle and (ii) a dozing level of a driver of the own vehicle; and
execute a secondary collision reducing control of executing a forcibly-decelerating process of forcibly decelerating the own vehicle when (i) a light collision condition that a light collision that the collision index value is within a predetermined light collision range occurs, is satisfied, and (ii) a dozing condition that the dozing level is higher than or equal to a predetermined threshold level, is satisfied,
wherein the electronic control unit is configured to execute the forcibly-decelerating process so as to decelerate the own vehicle with controlling a deceleration of the own vehicle such that the deceleration of the vehicle realized when (i) the light collision condition and the dozing condition become satisfied, and (ii) the dozing level is relatively low, is smaller than the deceleration of the own vehicle realized when the deceleration when (i) the light collision condition and the dozing condition become satisfied, and (ii) the dozing level is relatively high;
wherein the electronic control unit is configured to execute the forcibly-decelerating process by a forcibly-braking process of applying a braking force greater than or equal to a predetermined braking force to the own vehicle or by a driving force limiting process of limiting a driving force applied to the own vehicle to a value smaller than or equal to a predetermined driving force; and
wherein the electronic control unit is configured to:
execute the forcibly-decelerating process by the forcibly-braking process when (i) the light collision condition and the dozing condition become satisfied, and (ii) the dozing level is higher than or equal to a predetermined switching level which is higher than the predetermined threshold level; and
execute the forcibly-decelerating process by the driving force limiting process when (i) the light collision condition and the dozing condition become satisfied, and (ii) the dozing level is lower than the predetermined switching level.
