  • Patent number: 11827239
    Abstract: In an autonomous driving control apparatus, a control unit controls autonomous driving that causes a vehicle to travel along a scheduled travel route. A storage unit stores driving-operation modules. Each of the driving-operation modules is comprised of a modularized set of a sequence of input/output operations used by a corresponding driving operation carried out by the autonomous driving. The control unit determines the scheduled travel route, and determines, in accordance with the scheduled travel route, at least one selected driving-operation module from the driving-operation modules stored in the storage unit. The control unit performs the at least one selected driving-operation module to thereby cause the vehicle to perform the autonomous driving.

  • Publication number: 20220379894
    Abstract: A driving support device includes a prediction unit, a trajectory determination unit, and a necessity determination unit. The prediction unit is configured to predict an increase degree of an inter-vehicle distance between other vehicles in response to the cut-in of the subject vehicle, and determine whether the lane change is permissible based on the increase degree. The necessity determination unit is configured to determine whether a necessity level of the lane change is within an acceptable range. The prediction unit is configured to cancel the determination whether the lane change is permissible based on the increase degree when it is determined that the necessity level is within the acceptable range, and determine whether the lane change is permissible based on a linear prediction of a behavior of the other vehicles.

  • Patent number: 9802263
    Abstract: In an electrical discharge machine that applies a voltage between an electrode and a workpiece to generate electrical discharge, an electrode holder holds the electrode. An ultrasonic motor has a fingertip that comes into contact with electrode holder, and moves electrode holder in a driving direction by moving the fingertip in an annular manner at an ultrasonic-range frequency. A roller bearing guides the movement of the electrode holder in the driving direction. A control circuit controls a position of the electrode in the driving direction by driving the ultrasonic motor, and moves the electrode holder based on an abnormality occurring in resistance against the movement of the electrode holder in the driving direction such that the electrode holder is moved by a movement distance equivalent to when the largest roller element among a plurality of roller elements of the roller bearing rolls and rotates once without sliding or longer.
