Abstract: In a driving assistance device, a distance information is acquired based on an image acquired by an imaging device mounted on a vehicle. The distance information includes a relative distance of a preceding vehicle in a travelling direction of the own vehicle, relative velocity thereof, and acceleration information thereof including relative acceleration. A time required until the own vehicle collides with the preceding vehicle is calculated with consideration of m the acceleration information as a predicted collision time. It is determined whether or not the preceding vehicle is in a deceleration state by using the relative velocity. Further it is determined whether or not a collision possibility between the own vehicle and the preceding vehicle exists, and it is also determined to use the is predicted collision time on the condition that the preceding vehicle is determined to be in the deceleration state and the collision possibility is determined to exist.

Abstract: A traveling assistance apparatus controls a safety apparatus for avoiding collision between an own vehicle and an object, based on detection information from an object detection apparatus. The assistance apparatus calculates a predicted time to collision of a target object and the own vehicle, and operates the safety apparatus in response to the predicted time to collision being equal to or less than a predetermined operation timing. In response to a steering operation by a driver for collision avoidance of the own vehicle being performed, the assistance apparatus performs operation-stop in which operation of the safety apparatus is stopped or operation-delay in which the operation timing is delayed. The assistance apparatus suppresses the operation-stop or the operation-delay in response to a target object serving as a collision avoidance target being recognized in a path of the own vehicle after the steering operation by the driver, based on the detection information.

Abstract: A brake assistance apparatus for a vehicle is provided. The brake assistance apparatus includes a detecting unit and a brake assistance control unit. The detecting unit detects a state surrounding an own vehicle. The brake assistance control unit performs brake assistance to brake the own vehicle at a first brake timing, based on the detected state surrounding the own vehicle. In response to the own vehicle being determined to be advancing at an intersection based on the detected state surrounding the own vehicle, the brake assistance control unit performs the brake assistance at a second brake timing that is later than the first brake timing.
