Abstract: A control device that comprises a processor that executes instructions to cause a mobile object to travel autonomously is provided. The processor controls the mobile object based on a conditions-varying travel path so that an automated control of the mobile object does not change even if travel conditions of the conditions-varying travel path vary. The processor also executes instructions to determine a route to a destination. The processor determines the route using automated-driving map information that comprises a travel path other than the conditions-varying travel path when the mobile object travels by automated driving. The processor also determines the route using manual-driving map information that comprises the conditions-varying travel path when the mobile object travels by manual driving.

Abstract: A vehicle control device, a vehicle control method, and a non-transitory computer readable storage medium capable of increasing the traveling safety in the case where an overtaking vehicle approaches in the traveling control of the own vehicle are provided. A vehicle control device includes: a recognition part, recognizing an overtaking vehicle presumed to overtake an own vehicle from rear of the own vehicle in an own lane in which the own vehicle travels; and a driving control part, automatically controlling at least acceleration and deceleration of the own vehicle, and, in a case where the overtaking vehicle is recognized, determining a traveling velocity of the own vehicle based on a number of lanes of a road on which the own vehicle travels.

Abstract: According to an embodiment, a vehicle control device includes a recognizer configured to recognize surroundings of a host vehicle, and an avoidance controller configured to able to execute first avoidance control for avoiding contact with a physical object recognized by the recognizer according to braking of the host vehicle and second avoidance control for avoiding the contact with the physical object recognized by the recognizer according to movement of the host vehicle in a vehicle width direction. When the contact between the host vehicle and the physical object is avoided, the avoidance controller selects either the first avoidance control or the second avoidance control on the basis of a lane type of a host vehicle lane recognized by the recognizer and preferentially executes the selected avoidance control.

Abstract: A control device includes a travel controller configured to cause a mobile object to travel autonomously. The travel controller controls the mobile object such that a behavior in which control details for the mobile object do not change even if travel conditions of a conditions-varying travel path in which the travel conditions vary according to a time period vary is performed.

Abstract: A control device detects an object that is present in a traveling direction of a road on which a mobile object is traveling, controls a behavior of the mobile object, acquires an operation state of a turn signal, causes, when a degree of proximity between the mobile object and the detected object is less than a reference, the mobile object to move in a direction intersecting the traveling direction when a predetermined time has elapsed from starting of operating the turn signal obtained from the operation state of the turn signal, and causes, when the degree of proximity is equal to or greater than the reference, the mobile object to move in the direction intersecting the traveling direction before the turn signal is operated or before a predetermined time has elapsed from starting of operating the turn signal.

Abstract: A motor driving device and driving method of the same used to surely suppress the influence of counter electromotive force is provided. The motor driving device 100 includes an auto-decay portion 141. The auto-decay portion 141 controls a path of a electric current flow in a motor coil when supplying the electric current and when decaying the electric current. The influence of counter electromotive force generated in a stepping motor 200 can be suppressed by the auto-decay portion 141 configured to control so that a ratio or an decay time of a slow decay mode and a fast decay mode of previous cycle is different from a ratio or an decay time of the slow decay mode and the fast decay mode of current cycle.
