A method and system for identifying an object in one space monitored by at least one radar transceiver. The method comprises storing intervals of critical distance values (10) associated with the position of a fixed object upon which a time-varying radio signal shadow may be generated, which may be confused with a moving object. Through successive radar detections, the signals are processed and generate a measurement range profile (40), from which a background range profile (41) is extracted to obtain an object range profile (50). The distance of a possible detected object (60) is determined from the analysis of the object range profile. If the distance of the object (4) is external to the critical intervals (51), the object is classified as valid (55). If the distance is internal to the intervals, the detected object may be a shadow and unless further checks are performed, its presence is not indicated.

An object-detecting device includes a first detector, an object tracker, a second detector, and an axial misalignment determiner. The first detector detects a distance between a moving body and an object and an orientation of the object relative to the moving body based on detection information acquired from detection sensors including a search wave sensor that searches a detection region with a search wave. The object tracker tracks the same object passing through a different detection region based on the detection information. The second detector detects at least either one of a height of the object or a lateral distance of the object as object information based on the detection information. The axial misalignment determiner determines whether axial misalignment has occurred in the search wave sensor based on the distance and the orientation of the object detected by the first detector based on the detection information from the search wave sensor and the object information detected in a different detection region by the second detector.

A method, system and computer program product for intelligent tracking and transformation between interconnected sensor devices of mixed type is disclosed. Metadata derived from image data from a camera is compared to different metadata derived from radar data from a radar device to determine whether an object in a Field of View (FOV) of one of the camera and the radar device is an identified object that was previously in the FOV of the other of the camera and the radar device.

A method for distance control of a subject vehicle in relation to a front vehicle. The method includes setting, by an adaptive cruise control of the subject vehicle, an automatic distance control mode, wherein: a front object in front of the subject vehicle is detected by an environmental detection system of the subject vehicle, the front object is recognized as the front vehicle, and a distance to the front vehicle is regulated to an adaptive cruise control (ACC) target distance. The method further includes establishing that a safe following driving situation is present based on at least one criteria being met. The method additionally includes outputting, to a driver upon establishing that the safe following driving situation is present, a display signal, and setting, upon input of a confirmation signal by the driver, an automatic distance control platooning mode.

A system for tracking the movement of an object includes a radar device having a first field of view. The radar device generates radar data indicating one of a range corresponding to a distance of a moving object within the first field of view from the radar device and a range rate corresponding to a rate at which the distance is changing relative to the radar device. The system also includes an imager having a second field of view at least partially overlapping the first field of view in an overlap field of view. The imager generates imager data measuring, when the object is in the second field of view, an angular position of the object relative to the imager in at least one dimension. In addition, the system includes a processor combining the radar data and imager data, when the object is in the overlap field of view, to identify a track of the object in at least two dimensions.

An electronic device that selectively performs a predefined action is described. The predefined action can be any action performed by the electronic device, such as changing the power state of the electronic device or a component, change the state of a display, initiating a process, ending a process, etc. During operation, the electronic device may transmit a wireless signal. Then, the electronic device may receive a wireless-return signal associated with an object, which can indicate a time-of-flight of the wireless signal between the electronic device and the object. Moreover, the electronic device may determine a range between the electronic device and the object based at least in part on the wireless-return signal. When the range between the electronic device and the object is less than a threshold value, the electronic device may determine: whether the range between the electronic device and the object is varying and/or whether to perform the predefined action.

An approach is provided for detecting a presence of a physical divider on a road segment. The approach, for example, involves receiving sensor data from a vehicle traveling a road segment. The sensor data indicates a distance from the vehicle to the physical divider, a cross-sensor consistency of detecting the physical divider between at least two sensors of the vehicle, or a combination thereof. The approach also involves determining that the sensor data indicates the presence of the physical divider based on determining that the distance is within distance criteria, the cross-sensor consistency is within consistency criteria, or a combination thereof. The approach further involves updating data provided by a physical divider signal from the vehicle to indicate the presence of the physical divider on the road segment.
