Abstract: The present invention provides a moving object controller and a moving object control method capable of selecting a movement plan based upon detection accuracy of external information. A moving object controller 100 includes a plan generation unit 110 that generates at least one movement plan based upon external information on an external world of a moving object 1 and internal information on an internal part of the moving object; an accuracy estimation unit 120 that estimates detection accuracy of the external information based upon the external information, the internal information, and predetermined past information, among the movement plans generated by the plan generation unit; and a plan selection unit 130 that selects a movement plan of an execution target from among the movement plans generated by the plan generation unit based upon the detection accuracy of the external information estimated by the accuracy estimation unit.

Abstract: The present invention relates to methods and apparatuses for performing driving assistance for a controlled vehicle, involving determining a longitudinal acceleration target value on the basis of a lateral acceleration of the controlled vehicle and one or more setting parameters, and controlling a longitudinal acceleration of the controlled vehicle on the basis of the calculated longitudinal acceleration target value. According to the invention, a lateral acceleration acting, during cornering, on a proceeding vehicle, which moves in the longitudinal direction on the road ahead of the controlled vehicle, is estimated, and the one or more setting parameters for the calculation of the longitudinal acceleration target value are set based on the estimated lateral acceleration acting on the proceeding vehicle during cornering.
