  • Patent number: 11789444
    Abstract: A movement control method for a multi-vehicle system for moving multiple vehicles to target positions individually set for the vehicles includes: acquiring first positions of the vehicles; determining control input for moving the vehicles from the first positions to second positions away from the target positions by a first distance or more while the vehicles satisfy a predetermined condition; and updating the first distance to be a shorter distance when a distance between the second position and the target position of each of the vehicles becomes equal to or more than the first distance and within an updating distance.
    Type: Grant

  • Patent number: 11556135
    Abstract: A method of controlling movement of multi-vehicle includes acquiring a constraint condition under which vehicles move and a calculation cycle for calculating movement routes of the vehicles; acquiring a position of each vehicle; specifying a target position for each vehicle; calculating, based on the position of each vehicle, the target position, and the constraint condition, a movement route for prediction steps of each vehicle; determining, based on the movement routes of the vehicles, a driving condition of each vehicle from a current time to a unit time; and controlling movement of each vehicle. Calculating the movement route including performing optimization calculation based on an evaluation function, evaluation of which becomes higher as a deviation between the vehicle and the target position for each prediction step becomes smaller, and the constraint condition, to calculate the movement route.

  • Patent number: 10338922
    Abstract: A second core calculates an intervening variable that is defined by an inner function, when a time derivative of a state variable is expressed by a function having the state variable, the inner function, and an observable input variable as independent variables. A first core calculates a function by using respective values of the state variable, the intervening variable, and the input variable, and obtains a value of the state variable by time-integration of a value of the function. In the calculation of the function, the value of the state variable calculated in previous time, a value of the intervening variable calculated by the second core in the previous time, and a value of the input variable inputted in this time are used.
