  • Patent number: 11410332
    Abstract: A map system is a system for autonomously navigating a vehicle along a road segment and includes at least one processor. The processor acquires at least one image representing the environment of the vehicle from the imaging device, acquires the brightness of the environment of the vehicle, analyzes the image to calculate the position of the landmark with respect to the road on which the vehicle travels, determines the position of the own vehicle based on the position of the landmark calculated from the image and the map information stored in the server, and emits an illumination light in a direction in which a presence of the landmark is estimated when the brightness is equal to or less than a predetermined threshold value.

  • Patent number: 9581981
    Abstract: A method for a continuation model predictive control (CMPC) of a system determines at least a part of a preconditioner using an approximate coefficient function and determines a solution vector by solving a matrix equation of the CMPC with a coefficient matrix defined by an exact coefficient function at a current time step of a control using an iterative method with the preconditioner. The approximate coefficient function applied to a vector approximates a result of an application of the exact coefficient function to the vector. A control signal for controlling the system is generated using the solution vector.
