Abstract: An autonomous vehicle control device configured to determine a control input for causing an automatic driving to travel along a target trajectory determined based on an estimated current location of the vehicle by repeatedly performing a predetermined calculation, wherein the controller estimates the current location by correcting the location of the vehicle on the map data based on the relative location of the vehicle on the traveling road, and adjusts a predetermined parameter in the predetermined calculation in accordance with the amount of correction so that the number of repeated calculations is reduced when it is determined that the estimation of the current location is not accurate based on the amount of correction of the location at that time.

Abstract: A control device for causing a vehicle to travel by autonomous driving based on a target path calculated based on a current position on map data of a vehicle estimated by a map data, a behavior detection sensor, and an external detection sensor, wherein a current position of the vehicle is estimated by correcting a position on map data of the vehicle in accordance with a relative position of the vehicle on a roadway, a correction amount at that time is obtained, a change in a correction amount is predicted by map data and an external detection sensor, and a control gain in a control input when the vehicle is caused to travel by autonomous driving is changed in accordance with the change, thereby changing a characteristic of the traveling control.

Abstract: A control mode of speed control includes a first control mode in which an actual speed is caused to follow a target speed through active use of a brake and a second control mode in which the actual speed is caused to follow the target speed while use of the brake is suppressed. An autonomous driving system changes a threshold value to a value larger than a value in the first control mode when the control mode is switched from the first control mode to the second control mode, and changes the threshold value to a value smaller than a value in the second control mode when the control mode is switched from the second control mode to the first control mode.
