  • Patent number: 11572079
    Abstract: An apparatus and a method for controlling a velocity of an autonomous driving vehicle is provided. The method includes steps of: obtaining information of an environment surrounding the vehicle when an obstacle is detected to be on a planning path of the vehicle; obtaining an initial reference velocity profile of the vehicle; determining a safety factor based on the initial reference velocity profile, the information of the environment and information of the vehicle, wherein the safety factor at least comprises a safety distance between the vehicle and the obstacle for the vehicle to follow the obstacle; determining an optimized reference velocity profile based on the information of the environment, the information of the vehicle and the safety factor; and performing the step of determining the safety factor by using the optimized reference velocity profile as the initial reference velocity profile and the step of determining the optimized reference velocity iteratively.

  • Publication number: 20200363816
    Abstract: A method for controlling a vehicle using a model predictive controller generating consecutive sets of reference states at a calculation frequency. In one embodiment, the method comprises: receiving a trajectory reference for guiding movement of the vehicle; generating, in a calculation cycle repeated at the calculation frequency, a set of reference states based on an initial state of the vehicle at a start time of the calculation cycle and the trajectory reference; sending the set of reference states to a second controller; detecting, by the second controller at a detection frequency equal to or higher than the calculation frequency, an updated state of the vehicle; generating a vehicle control parameter value based on the updated state of the vehicle and a reference state of the set of reference states; and controlling the vehicle using the vehicle control parameter value.

  • Publication number: 20200341474
    Abstract: A method and device for generating an autonomous driving trajectory of a vehicle are provided. The method comprises: acquiring information of an external environment wherein the vehicle is currently traveling; defining an envelope based on the information of the external environment, wherein the envelope defines a predicted travelable region of the vehicle in a subsequent predetermined time period; generating a reference path for the subsequent predetermined time period based on the envelope; and modifying the reference path based on a current lateral state of the vehicle or a road marker within the external environment, so as to generate the autonomous driving trajectory of the vehicle.
