摘要： Methods and systems for out-of-distribution (OOD) detection in autonomous driving systems are described. A method for use in an autonomous driving system may include filtering feature vectors. The feature vectors may be filtered using a first filter to obtain clusters of feature vectors. The method may include assigning one or more images to a respective cluster based on a feature vector of the image. The method may include filtering a subset of the images using a second filter to determine a classification model. The method may include storing the classification model on a vehicle control system of a vehicle. The method may include detecting an image using a vehicle sensor. The method may include classifying the detected image based on the classification model. The method may include performing a vehicle action based on the classified detected image.

摘要： Disclosed are a road feature point extraction method and system. The road feature point extraction method comprises: acquiring map information for the current position of a vehicle, wherein the map information comprises the attributes of the current road and the attributes of the next road section; comparing the attributes of the current road with the attributes of the next road section to determine the road type of the next road section; and extracting, in conjunction with the road type of the next road section and the map information corresponding to the next road section, a road feature point representing a road scene on the next road section, and outputting the name of the extracted road feature point and information of the relative distance between the road feature point and the vehicle.

摘要： Disclosed are a data fusion method and apparatus for a vehicle sensor, the method comprising: reading a parameter attribute set of each target detected by a sensor arranged on a vehicle, wherein the parameter attribute set at least comprises one or more of the following: longitudinal velocity, longitudinal distance and transverse distance; generating an attribute combination according to the read parameter attribute set of each target detected by each sensor; and determining an overlap ratio of the parameter attribute set in each attribute combination, and carrying out data fusion based on the overlap ratio so as to obtain a first data fusion list, wherein the first data fusion list comprises the overlap ratio of each attribute combination and the parameter attribute set corresponding to the overlap ratio of each attribute combination. The method simplifies determination logic of a subsequent decision-making system and improves security and operating efficiency of the whole system.

摘要： Methods and systems for decision making in an autonomous vehicle (AV) are described. A vehicle control system may include a control unit, a perception unit, and a behavioral planning unit. The behavioral planning unit may include an intent estimator that receives a first set of perception information from the perception unit. The behavioral planning unit may include a motion predictor that receives the first set of perception information from the perception unit. The behavioral planning unit may include a function approximator that receives a second set of perception information from the perception unit. The second set of perception information is smaller than the first set of perception information. The function approximator determines a prediction, and the control unit uses the prediction to control an operation of the AV.
