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.

Braking control device

In a collision avoidance apparatus for a vehicle, a collision avoidance controller is configured to calculate a movement trajectory of a moving object moving on a road crossing a road that the vehicle is traveling on from a succession of locations of the moving object, calculate a movement trajectory of the vehicle using a speed of the vehicle, determine whether the movement trajectory of the moving object is a trajectory of a moving object likely colliding with the vehicle, and in response to determining that the movement trajectory of the moving object is a trajectory of a moving object likely colliding with the vehicle and that the moving object fails to be recognized by a camera due to a view of the moving object being obstructed, calculate a risk index for determining a collision avoidance measure and employ the collision avoidance measure in dependence upon the risk index.

Collision avoidance apparatus for vehicle

In an apparatus for controlling a vehicle equipped with an autonomous sensor and a communication unit, an object detector is configured to determine whether a predefined mobile-object condition is met, where the predefined mobile-object condition indicates that a mobile object detected from detection information received from an external device via the communication unit and a mobile object detected from detection information acquired from the autonomous sensor are the same object. An occupant assister is configured to perform occupant assistance for assisting an occupant of the vehicle, and configured to, in response to a detection accuracy condition being met, determine a mode of occupant assistance as a first mode, and in response to neither the detection accuracy condition nor the mobile-object condition being met, determine the mode of occupant assistance as a second mode is different from the first mode.

Provided is a vehicle braking support device. 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.

Vehicle braking support device and braking support control method

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

A driving support system mountable to an own vehicle includes an object detection sensor detecting a first object, a communication unit performing communication with a second object around the own vehicle, a direction determining unit determining whether a first direction from the own vehicle to the first object is the same as a second direction from the own vehicle to the second object with which the communication unit performs communication, an identity determining unit determining whether the first object is identical with the second object based on information acquired by the object detection sensor and the communication unit when the first direction is the same as the second direction, and a driving supporting unit performing driving support based on information acquired from an object determined in advance between the first object and the second object when it is determined that the first object is identical with the second object.

When there is a possibility of collision between a host vehicle and objects positioned in a detection region in front of the host vehicle, an ECU implements collision avoidance control for preventing the host vehicle from colliding with an object. The ECU detects the objects positioned in the detection region and judges whether, among the detected objects, there is an object that the host vehicle has overtaken and that is capable of moving within a prescribed range in the vehicle width direction of the host vehicle. If it is judged that the host vehicle is turning to the left or to the right after it has been judged that the host vehicle has overtaken an object, the actuation timing of the collision avoidance control is advanced.
