Abstract: A two-way communication device system includes: a first two-way communication device; and a second two-way communication device installed at a different location from the first two-way communication device and configured to communicate with the first two-way communication device The two-way communication device system creates an operator input operation history when an input operation is received for the first time, transmits an input signal to the second two-way communication device, creates an other-device input operation history when an input signal is received for the first time, maintains a first state when both the operator input operation history and the other-device input operation history do not exist, a second state when only one of the operator input operation history and the other-device input operation history exists, and a third state when both of the operator input operation history and the other-device input operation history exist, and deletes both the operator input operation history and the

Abstract: Based on schedule information indicating one or more events to be occurred and information relating to a location associated with each of the one or more events, a navigation method estimates an area and time at which congestion may be likely to occur in the vicinity of the location. Furthermore, the navigation method presents to a moving body information which is based on the estimated result of the area and the time, and which is related to a movement plan when moving using the moving body.

Abstract: Provided is a moving vehicle which enables a user to easily recognize that the moving vehicle is stopped due to the user's own clothing or the like being determined as an object, thereby enabling the user to cancel the stopped state and return to a moving state. A moving vehicle on which a person rides and which stops moving if the distance to an object is equal to or less than a first predetermined value, said moving vehicle comprising: a sensor (124) for detecting the distance; a determiner (125) for determining, if the distance is equal to or less than a second predetermined value smaller than the first predetermined value, a state in which the field of view of the sensor (124) is blocked due to the clothing covering the sensor (124); and a notifier (128) that, if said state is determined by the determiner (125), issues a notification.

Abstract: According to a control method for an electric vehicle of the present invention, when an electric vehicle (100) moves at a first velocity and approaches an object (200) on the basis of instructed information, the electric vehicle (100) is temporarily stopped at a position at which the distance between the electric vehicle (100) and the object (200) is a first stopping distance, after which the velocity is switched to a second velocity that is slower than the first velocity, the electric vehicle (100) is caused to approach the object (200), and the electric vehicle (100) is stopped at position at which the distance between the electric vehicle (100) and the object (200) is a second stopping distance that is shorter than the first stopping distance.

Abstract: A moving body includes a frame, a pair of right and left first wheels, a pair of right and left second wheels, a pair of right and left first parallel links connecting the first wheels and the second wheels, and a second parallel link connecting the pair of right and left first parallel links. Furthermore, a height changing unit connects the second parallel link and the frame and changes a position of the frame in a height direction with respect to the second parallel link, and a controller controls the height changing unit so as to maintain a height of the frame from a road surface.

Abstract: An electric vehicle includes a first instructor operated by a first operator; a second instructor operated by a second operator; a third instructor performing an instruction of deceleration or stop by determining a possibility of collision; a controller for selecting one of instructions from the first instructor, the second instructor, and the third instructor; and a driver driving according to the instruction from the controller, in which in a case of receiving the instructions from at least the first instructor and the third instructor, the controller preferentially selects the instruction from the third instructor to the instruction from the first instructor.

Abstract: A mobile unit which suppresses an increase in weight and/or costs and/or a decrease in reliability is disclosed. In a mobile unit capable of turning movement, a right-hand part and a left-hand part are involute shaped, and a center point of a base circle of the involute shape passes through at least one axis among center axes of turning movement.

Abstract: A parking lock device includes: a transmission shaft supported by a first case and a second case and connected to drive wheels; a parking gear fixed to the transmission shaft; and a parking pole engageable with the parking gear. A cover member is fixed to an inner wall surface of the second case. The cover member covers at least an outer peripheral surface of the parking gear with a predetermined clearance therebetween in a state where the second case is joined to the first case. When the second case to which the cover member is attached in advance is joined to the first case to which the parking gear is attached in advance, the cover member is guided by the outer peripheral surface of the parking gear. Thus, the second case 13 can be joined to the first case easily.
