  • Publication number: 20190184898
    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 task of the set of tasks by which the task is to be completed. A set of warnings to alert the driver to perform the set of tasks is determined based on a current state of the driver, wherein each warning corresponds to a task in the set of tasks. 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: 20190187701
    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: 20190185011
    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. Lane control for the autonomous vehicle is planned based on the detected current lane and self-aware capability parameters in accordance with a driving 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. The driving lane control model is generated based on recorded human driving data to achieve human-like lane control behavior in different scenarios.

  • Publication number: 20190184997
    Abstract: The present teaching relates to method, system, and medium, for operating a vehicle. The method includes the steps of receiving Real-time data related to the vehicle are received. A current mode of operation of the vehicle is determined. A first risk associated with the current mode of operation of the vehicle is evaluated based on the real-time data in accordance with a risk model. If the first risk satisfies a first criterion, a second risk associated with switching the current mode to a different mode of operation of the vehicle is determined. The vehicle is switched from the current mode to the different mode if the second risk satisfies a second criterion.

  • Publication number: 20190185013
    Abstract: The present teaching relates to method, system, medium, and implementation of human-like vehicle control for an autonomous vehicle. Recorded human driving data are first received, which include vehicle state data, vehicle control data, and environment data. For each piece of recorded human driving data, a vehicle kinematic model based vehicle control signal is generated in accordance with a vehicle kinematic model based on a corresponding vehicle state and vehicle control data of the piece of recorded human driving data. A human-like vehicle control model is obtained, via machine learning, based on the recorded human driving data as well as the vehicle kinematic model based vehicle control signal generated based on vehicle kinematic model. Such derived human-like vehicle control model is to be used to generate a human-like vehicle control signal with respect to a target motion of an autonomous vehicle to achieve human-like vehicle control behavior.

  • Publication number: 20190184897
    Abstract: The present teaching relates to method, system, and medium, for presenting a warning to a driver. An instruction indicating an upcoming change in an operating mode of the vehicle is obtained, wherein the instruction specifies a set of tasks to be completed by the driver and a task duration associated with each task. Information of a current state of the driver is obtained and used to determine a warning to be used to alert the driver to perform the change, wherein the warning includes warning content and indication of at least one media to be used to deliver the warning content. A warning schedule is generated to comprise a set of warnings, each warning corresponding to one task, and arranged in an order based on an order of the tasks. The warning schedule is transmitted so that each warning of the set of warnings is executed.

  • Publication number: 20140121011
    Abstract: A system for mobile simulated real-time player vs. player (PvP) gaming provides a user interface (UI) to a mobile device for simulated real-time player vs. player (PvP) gaming. A player selects an opponent and issues a challenge to the opponent's record on a song from the opponent's song list. The challenger then performs a simulated real-time challenge to the opponent's record on the song. If the challenger wins the challenge he/she is awarded bonus points. If the challenger loses, he can issue another challenge for the original song. To play a second round, the challenged player from the first round challenges the original challenger's record on the song. Winners get the right to a new challenge. Losers can purchase the right to a new challenge. Gameplay proceeds in a chain in which the players play alternating rounds.

    Abstract: An asynchronous, multiplayer game provides a user interface (UI) to a mobile device for asynchronous multiplayer gaming. By way of the UI, a team opens a game by selecting an opponent and provides notice to its team members of the newly-opened game. After team members join the game, opponents trade strategic and tactical moves asynchronously. In an embodiment, opposing guilds fight wars against each other to occupy fortresses held by an opponent and capture the opponent's rations.
