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 is prohibited in, 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.

The braking support device includes: detection units for detecting a state around a host vehicle; a braking support control unit for executing braking support by a braking device according to the detected state; and a vehicle stop control unit for maintaining a stopped state of a host vehicle after the host vehicle is stopped by the braking support control unit, and for releasing the stopped state of the host vehicle after a predetermined period has elapsed. The vehicle stop control unit, in a case where by using the detected state it is determined that it is desirable to maintain the stopped state of the host vehicle beyond the predetermined period, the vehicle stop control unit does not release the stopped state of the host vehicle until an operation by a driver is detected.

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.

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.

Control determines whether or not two objects represent the same object, in which one object is detected at a first position in front of a vehicle by an electromagnetic wave sensor and the other object is detected at a second position in front of the vehicle by image sensor. The control further determines whether or not the other object is partially excluded from an image acquired by the image sensor, in which a part of the object may have been outside the imaging region of the image sensor. The control changes a determination condition used for determining whether or not the objects represent the same object, such that the object whose part is excluded from the acquired image is more easily determined as the same object, compared with an object determined that such a part is not excluded from the acquired image.

An ECU determines that detected first and second objects are identical as an identical object based on a first position of the first object and a second position of the second object, and calculates the position of a target object that is determined as the identical object. The ECU determines whether a current situation is such that a reliability of the identicalness determination is at a predetermined level or higher. In a case of determining the current situation to be such that the reliability is at the predetermined level or higher, the ECU calculates the position of the target object based on a first distance and a second orientation. In a case of determining the current situation not to be such that the reliability is at the predetermined level or higher, the ECU calculates the position of the target object based on a second distance and the second orientation.
