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.

Traveling assistance apparatus

In a driving assistance apparatus, an object detecting unit detects an object that is present in a periphery of an own vehicle based on an image captured by an imaging apparatus provided in the own vehicle. An avoidance control unit performs collision avoidance control for avoiding a collision between the detected object and the own vehicle when a collision between the object and the own vehicle is likely. A light distribution control unit switches irradiated light of an irradiation apparatus provided in the own vehicle between high beam and low beam based on a predetermined switching condition. The light distribution control unit performs switching suppression control to suppress switching of the irradiated light from high beam to low beam while the avoidance control unit is performing collision avoidance control in a case where the irradiated light is set to high beam.

A braking control device for controlling braking of a host vehicle. For a state in which a host vehicle is stopped in an intersection by automatic emergency braking and an oncoming vehicle is approaching in an oncoming lane, the host vehicle prohibits secondary braking, flashes a hazard lamp, and prohibits an idling stop. For a state in which it is determined in that the vehicle is stopped and it is determined in that it is safe for the vehicle to start moving, the host vehicle releases stop maintenance braking.

A braking assistance device for a vehicle includes an object sensing unit for sensing an object, an intersection entry determination unit for determining entry of a host vehicle into an intersection, and a braking assistance execution unit for executing braking assistance by a braking device so as to avoid or mitigate collision with the object. If the host vehicle is determined to be entering the intersection, the braking assistance execution unit determines, based on a sensing result from the object sensing unit, a traffic environment at the intersection, and controls execution of the braking assistance in accordance with the determined traffic environment.

Brake assistance apparatus and brake assistance control method for vehicle

In a vehicle control apparatus, an object recognizing block recognizes an object which is present around a vehicle. In cases where there is a possibility that the vehicle will collide with an object recognized by the object recognizing block, the apparatus performs automatic braking control which brakes the vehicle. If the driver depresses the accelerator pedal in a predetermined depressing state, a braking controlling block cancels the automatic braking control. When an operation determining block determines that there is a driver's predetermined shift-lever position change, with which the driver's predetermined shift-lever position change is carried out during a driver's accelerator pedal depressing operation, the braking controlling block responds to a driver's accelerator depressing operation by not cancelling the automatic braking control or by making cancellation of the automatic braking control more difficult.

The avoidance operation controller uses a region which is narrower in a direction perpendicular to the travelling direction and parallel to a horizontal direction as the determination region when it is the situation that there exists no moving object than when it is not the situation that there exists no moving object.
