  • Patent number: 10936886
    Abstract: The present teaching relates to method, system, medium, and implementation of estimating a pose of an object in autonomous driving. Stereo images are obtained from a scene via at least two cameras. Objects present in the scene are then detected from the stereo images. For each object detected, a plurality of feature points are identified and depth information associated with the feature points are obtained. An orientation of each object is then estimated based on the feature points and depth information of the object and the pose of the object is then estimated based on the orientation and additional features of the object.

  • Publication number: 20200353926
    Abstract: The present teaching relates to method, system, and medium, for operating a vehicle. Real-time data related to the vehicle are received. A current mode of operation of the vehicle and a state of the driver present in the vehicle are determined. A first risk associated with the current mode of operation of the vehicle is evaluated based on the real-time data and the state of the driver in accordance with a risk model. In response to the first risk satisfying a first criterion, a second risk associated with switching the current mode to a different mode of operation of the vehicle is determined based on the state of the driver. The vehicle is switched from the current mode to the different mode when the second risk satisfies a second criterion.

  • Publication number: 20200192360
    Abstract: The present teaching relates to method, system, and medium, for switching a mode of a vehicle. Real-time data related to the vehicle are received, which include intrinsic/extrinsic capability parameters, based on which a set of tasks to switch from a current mode to a different mode is determined. A first duration of time required for the switch is determined based on a first risk evaluated with respect to the current mode and the real-time data. A task duration time needed by a driver to complete the task is estimated for each of the set of tasks. A second risk for the switching is estimated based on the required first duration of time and a total task duration times needed to complete the set of tasks. The switch is carried out when the second risk satisfying a criterion.

  • Publication number: 20190389379
    Abstract: The present teaching relates to method, system, and medium, for generating an augmented alert in a hybrid vehicle. First information indicating an upcoming switch in an operating mode of the vehicle is received, which specifies a set of tasks, arranged in an order, to be completed by a driver in the vehicle to achieve the upcoming switch, and a task duration for each of the set of tasks by which the task is to be completed. A current state of the driver is obtained and used to determine a set of warnings to alert the driver to perform the set of tasks. Each warning corresponds to a task in the set of tasks and is created based on the current state of the driver. A warning schedule is generated based on the set of warnings in the order of the set of tasks and transmitted so that warnings in the warning schedule are delivered to the driver.

  • Publication number: 20190206075
    Abstract: The present teaching relates to method, system, medium, and implementation of determining depth information in autonomous driving. Stereo images are first obtained from multiple stereo pairs selected from at least two stereo pairs. The at least two stereo pairs have stereo cameras installed with the same baseline and in the same vertical plane. Left images from the multiple stereo pairs are fused to generate a fused left image and right images from the multiple stereo pairs are fused to generate a fused right image. Disparity is then estimated based on the fused left and right images and depth information can be computed based on the stereo images and the disparity.

  • Publication number: 20190185010
    Abstract: The present teaching relates to method, system, medium, and implementation of route planning for an autonomous driving vehicle. A source location and a destination location are first obtained, where the destination location is where the autonomous driving vehicle is to drive to. One or more available routes between the source location and the destination location are identified. A self-aware capability model is instantiated with respect to the one or more available routes and is predictive of the operational capability of the autonomous driving vehicle with respect to each of the one or more available routes. Based on the self-aware capability model, a planned route to the destination location is then automatically selected for the autonomous driving vehicle.

  • Publication number: 20190187707
    Abstract: The present teaching relates to method, system, medium, and implementation of lane planning in an autonomous vehicle. Sensor data are received that capture ground images of a road the autonomous vehicle is on. Based on the sensor data, a current lane of the road that autonomous vehicle is currently occupying is detected. Information indicating presence of a passenger in the vehicle is obtained and used to retrieve a personalized lane control model related to the passenger. Lane control for the autonomous vehicle is planned based on the detected current lane and self-aware capability parameters in accordance with the personalized lane control model. The self-aware capability parameters are used to predict operational capability of the autonomous vehicle with respect to a current location of the autonomous vehicle.
