摘要： When a likelihood of a collision between an object and an own vehicle is determined to be present, an vehicle control apparatus calculates an object width indicating a size of the object in a lateral direction and an overlap ratio indicating a proportion of an amount of overlap in the lateral direction between the calculated object width and a determination area that is virtually set ahead of the own vehicle. Based on the calculated overlap ratio, an operation timing for a collision avoidance control is set. The object width is changed when the overlap ratio is less than a predetermined threshold such that the object width is less than the object width when the overlap ratio is greater than the predetermined threshold. The operation timing for the collision avoidance control is set based on a new overlap ratio calculated based on the determination area and the object width after change.

摘要： A vehicle control apparatus accumulates a history of timings of avoidance operations performed by a driver of with respect to objects that are at prescribed distances ahead of a host vehicle, and calculates a distribution of the timings of the avoidance operations. Based on the distribution of the timings of the avoidance operations, the vehicle control apparatus sets the output timing of a warning to the driver such that interference does not occur between the avoidance operation and an avoidance operation that is actually performed by the driver, and furthermore the vehicle control apparatus judges the risk of a collision with the host vehicle, with the judgement based on the position of an object that is ahead of the host vehicle, and changes the output timing of the warning based on results of the judgement of risk.

摘要： A system and method for providing target selection and threat assessment for vehicle collision avoidance purposes that employ probability analysis of radar scan returns. The system determines a travel path of a host vehicle and provides a radar signal transmitted from a sensor on the host vehicle. The system receives multiple scan return points from detected objects, processes the scan return points to generate a distribution signal defining a contour of each detected object, and processes the scan return points to provide a position, a translation velocity and an angular velocity of each detected object. The system selects the objects that may enter the travel path of the host vehicle, and makes a threat assessment of those objects by comparing a number of scan return points that indicate that the object may enter the travel path to the number of the scan points that are received for that object.

摘要： In a pedestrian determining apparatus, an object detecting unit detects, based on waves reflected by an object, the object as a radar-based object. The reflected waves are generated based on reflection, by the object, of radar waves transmitted ahead of the own vehicle. A likelihood calculating unit calculates, for the radar-based object, a likelihood of the radar-based object being a pedestrian crossing ahead of the own vehicle. A pedestrian determining unit determines whether the likelihood is equal to or higher than a predetermined threshold, and determines that the radar-based object is a pedestrian crossing ahead of the own vehicle if the likelihood is equal to or higher than the predetermined threshold. The likelihood calculating unit sets the likelihood for the radar-based object to be lower if the radar-based object is detected as a part of an object group arranged at regular intervals than otherwise.

摘要： Disclosed herein are an autonomous emergency braking system and a method of controlling the same, capable of autonomously performing emergency braking using information detected by a radar sensor. The autonomous emergency braking system includes a radar sensor and an ECU. The radar sensor transmits a radio wave and receives a wave reflected from an object in front of a vehicle, so as to detect the object in front of the vehicle. The ECU receives object detection information from the radar sensor, and stops or puts off autonomous emergency braking when the number of times the object is detected within a predetermined distance is equal to or greater than a predetermined number of times, based on the received object detection information.

摘要： Example metal bridge detection systems and methods are described. In one implementation, a method receives LIDAR data from a LIDAR system mounted to a vehicle and receives camera data from a camera system mounted to the vehicle. The method analyzes the received LIDAR data and the camera data to identify a metal bridge proximate the vehicle. If a metal bridge is identified, the method adjusts vehicle operations to improve vehicle control as it drives across the metal bridge.

摘要： In an object detection apparatus, a first region definition unit defines a first object region including a first detection point representing a relative position of a first object detected by a millimeter-wave radar with respect to a reference point in an XY-plane. An X-axis direction of the XY-plane is a vehicle widthwise direction, and a Y-axis direction of the XY-plane is a vehicle lengthwise direction. A second region definition unit defines a second object region including a second detection point representing a relative position of a second object detected based on a captured image with respect to the reference point. A region size modification unit modifies the size of the first region in the presence of axial misalignment of the radar. A determination unit determines that the first and second objects are the same if there is an overlap of the first and second object regions in the XY-plane.

摘要： A radar apparatus is provided to receive a transmission wave reflected by a target object by antennas. The radar apparatus includes a signal analysis unit to analyze reception waves, and to obtain amplitudes and phases of the reception waves, at a frequency with which reception strength shows a peak. The radar apparatus also includes a direction detection unit to detect a direction of the target object based on the phases of the reception waves, and an estimated amplitude and phase output unit to output estimated amplitudes and estimated phases of reception waves to be received, assuming that the target object exists in the detected direction. The radar apparatus further includes a comparison unit to compare the amplitude or phase obtained by the signal analysis unit with that output by the estimated amplitude and phase output unit.
