摘要： The object recognition device includes at least one sensor, a data reception unit, and a setting unit. The sensor detects an object present in a detectable range and transmits object data including a plurality of physical quantities indicating a state of the object. The data reception unit receives the object data from the sensor. The setting unit generates prediction data which predicts current object data based on at least a part of past object data received by the data reception unit and a motion model in the object, and sets a association possible region for determining a association between the prediction data and the current object data based on a plurality of physical-quantity delay times each corresponding to each of the plurality of physical quantities included in the prediction data.

摘要： There are provided an object recognition apparatus that raises the recognition accuracy for a surrounding object and a vehicle control apparatus, and an object recognition method and a vehicle control method. An object recognition apparatus receives object data, which is a state value of the object, from a first sensor for detecting a surrounding object; compares estimation data obtained through estimation of a state value of the object, based on recognition data calculated in a past period, with the object data, and determines whether or not the object data is data in a low-resolution state; then, in accordance with the determination result, calculates the state value of the object by use of object data and estimation data and then generates the state value as recognition data, so that the recognition accuracy for an object is raised.

摘要： In this object recognition device, an association between a first object detection result and a second object detection result is taken in a region excluding an occlusion area. When the first object detection result and the second object detection result are determined to be detection results for an identical object, a recognition result of the surrounding object is calculated from the first object detection result and the second object detection result. Thus, occurrences of erroneous recognition of an object can be decreased as compared to a conventional object recognition device of a vehicle.
