Abstract: Systems, methods, and other embodiments described herein relate to improving alert activation for rear collision avoidance. In one embodiment, a method includes responsive to detecting a target object that is located behind a subject vehicle, determining, by the subject vehicle, characteristics about a surrounding environment of the subject vehicle, including of the target object. The method includes analyzing the characteristics to identify lateral free space next to the subject vehicle that is an area without obstruction beside the subject vehicle. The method includes modifying a collision threshold for activating an alert to the target object according to the lateral free space.

Abstract: 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.

Abstract: System, methods, and other embodiments described herein relate to improving alerts to a passenger about hazards when exiting a subject vehicle. In one embodiment, a method includes, in response to identifying a target in a surrounding environment of the subject vehicle, estimating a target path of the target. The method includes selectively adjusting an activation threshold for providing an alert according to a curvature of the target path. The method includes activating the alert to inform the passenger of a hazard associated with the target according to whether the target path satisfies the activation threshold.

Abstract: In a diagnostic apparatus, a diagnostic unit diagnoses whether there is vertical misalignment. The vertical misalignment is misalignment of the probing beam with respect to a designed beam axis position in a vertical direction, i.e. a height direction, of the vehicle. Based on detection performance information representing whether target detection performance by the beam sensor is likely to be lower than a predetermined detection performance, a determining unit causes the diagnostic unit to execute diagnosis of the vertical misalignment upon the detection performance information representing, as a first detection state, that the detection performance is not likely to be lower than the predetermined detection performance. The determining unit disables the diagnostic unit from executing diagnosis of the vertical misalignment upon the detection performance information representing, as a second detection state, that the detection performance is likely to be lower than the predetermined detection performance.

Abstract: A diagnostic apparatus includes an obtaining unit for obtaining horizontal misalignment information indicative of whether there is horizontal misalignment in a probing beam. The diagnostic apparatus includes a diagnostic unit for diagnosing whether there is vertical misalignment. The vertical misalignment is misalignment of the probing beam with respect to a designed beam axis position in a vertical direction. The vertical direction corresponds to a height direction of the vehicle. The diagnostic apparatus includes a determining unit for determining, based on the horizontal misalignment information, whether the diagnostic unit executes diagnosis of the vertical misalignment. The determining unit causes the diagnostic unit to execute diagnosis of the vertical misalignment upon the horizontal misalignment information representing that there is no horizontal misalignment. The determining unit disables the diagnostic unit from executing diagnosis of the vertical misalignment upon the horizontal misalignment information representing that there is horizontal misalignment.

Abstract: An apparatus for detecting axial misalignment of a beam sensor calculates, based on a result of first target recognition tasks by a beam recognition unit and a result of second target recognition tasks by an image recognition unit, a percentage of the number of times at least one preceding vehicle, which is running in front of an own vehicle, is recognized by the pair of the first and second target recognition tasks to the number of times the at least one preceding vehicle is recognized by at least the image recognition task. The apparatus detects misalignment of the beam axis of the beam sensor in the vertical plane including the beam axis of the beam sensor in accordance with the calculated percentage.

Abstract: In an apparatus, an attention region defining unit defines an attention region near a blocking obstacle upon the blocking object being determined to be located between the own vehicle and the target object based on the results of the detection operations. The blocking object at least partly blocks a view from the own vehicle. A determiner determines whether the target object is located in the attention region. An obtaining unit obtains, upon it being determined that the target object is located in the attention region, a detection history of the target object by the object detection sensor before the target object is determined to be located in the attention region. An adjuster adjusts, based on the obtained detection history, a predetermined procedure of recognition for the target object upon it being determined that the target object is located in the attention region.

Abstract: An object type determination apparatus mounted in a vehicle. In the apparatus, a detection unit detects an object present forward of the vehicle. A height estimation unit estimates a height of the object detected by the detection unit from a road surface. A determination unit uses the estimation result of the height estimation unit to determine, according to one of a plurality of predefined criteria, whether or not the object is an object for which a collision avoidance process is performed. A complex environment estimation unit estimates a likelihood that a complex environment is present forward of the vehicle. A criterion selection unit selects the one of the plurality of predefined criteria used by the determination unit on the basis of the estimation result of the complex environment estimation unit.

Abstract: 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.
