Abstract: A system includes: one or more storage devices that store specific position information indicating a specific position where an autonomous vehicle has a possibility to require remote support; and one or more processors configured to set a first target route as a target route, determine whether an abnormality has occurred in a remote support system, when the abnormality is detected in the remote support system, search for an alternative route that is a route to the destination based on the specific position information, the alternative route having a smaller number of the specific positions to be passed through by the autonomous vehicle than the first target route, when the alternative route is found, change the target route from the first target route to the alternative route, and control the autonomous vehicle.

Abstract: A vehicle control system is applied to a vehicle equipped with a magnetic sensor configured to detect a magnetic marker on a road. The vehicle control system executes a self-driving control by which self-driving of the vehicle is controlled. The vehicle control system executes a retreat traveling control using the magnetic marker in response to the occurrence of an abnormality in at least part of components and functions necessary for the self-driving control. The magnetic marker provides guidance information by which the vehicle is guided to a safe area. In the retreat traveling control using the magnetic marker, the vehicle control system acquires the guidance information from the magnetic marker detected by the magnetic sensor and causes the vehicle to travel toward the safe area and stop at the safe area based on the guidance information thus acquired.

Abstract: An autonomous driving system includes one or more storage devices configured to store specific position information indicating specific positions at which there is a possibility that remote assistance is required; and one or more processors configured to: determine presence or absence of an abnormality in a remote assistance system configured to provide the remote assistance to an autonomous driving vehicle; set, when an abnormality is detected in the remote assistance system, any one of the specific positions on a target route from a current position of the autonomous driving vehicle to a destination as a limit position based on the specific position information; set a target retracting position such that the target retracting position is included in the target route from the current position to the limit position; and control the autonomous driving vehicle such that the autonomous driving vehicle stops at the target retracting position.

Abstract: A vehicle includes an outside sensor configured to acquire information on an outside circumstance of the vehicle, a vehicle height adjusting device configured to adjust a vehicle height, and a control device configured to control the vehicle. The control device is configured to control the vehicle height adjusting device such that the vehicle height becomes a vehicle height corresponding to a platform condition at a predetermined stop position when the vehicle stops at the predetermined stop position. The control device is configured to control the vehicle height adjusting device based on a height of an obstacle such that the obstacle does not interfere with the vehicle when the obstacle is detected at the predetermined stop position by the outside sensor.

Abstract: An automatic driving system, that switches a driving state of a vehicle from automatic driving to manual driving due to a driver's operation during automatic driving of the vehicle, includes an electronic control unit configured to: determine whether a turning-off condition is satisfied when a direction indicator under the automatic driving is in a turned-on state and the driver's operation is performed; switch a driving state from the automatic driving to the manual driving and maintain the turned-on state of the direction indicator when the direction indicator is in the turned-on state and the driver's operation has been performed; determine whether the turning-off condition is satisfied based on a position of the vehicle under the manual driving or a traveling state of the vehicle under the manual driving; switch the direction indicator from the turned-on state to the turned-off state when it is determined that the turning-off condition is satisfied.

Abstract: A vehicle control system includes an actuator and an electronic control unit. The electronic control unit is configured to determine one of the following conditions is satisfied: (i) an adjacent vehicle has started; (ii) a first timing at which the preceding vehicle has started does not indicate a second timing at which a slipping-by vehicle has been lost; and (iii) a second preceding vehicle has started. The electronic control unit is configured to start the host vehicle by using the actuator when at least one of the conditions is satisfied.

Abstract: The present invention provides an inkjet recording head cartridge and an inkjet recording apparatus that have a simple structure and high reliability. Since individual flow passages in which ink emission orifices are formed are communicated directly with a rectangular ink supply chamber, it is prevented that a bubble of such a size as to cause printing defects rises through an ink supply chamber and blocks the individual flow passages. Also, since ink heated within the ink supply chamber is moved upward to the ink tank chamber by convection and grows an air lump sealed beforehand, it is prevented that a bubble will grow in the ink supply chamber. Furthermore, by allocating a large cross-sectional area to the ink supply chamber, it is prevented that meniscus oscillation of the ink emission orifices is amplified by pressure oscillation caused by ink emission and causes a printing defect. Therefore, reliable printing can be performed with a simple construction.

Abstract: The present invention provides a liquid jet printing head, a method of manufacturing the same, and a liquid jet printing apparatus, which allow stable, high speed, and continuous printing. A liquid jet printing head provides an inflow of liquid from an inlet to a common chamber, then along with the surface of heating elements of a heating element substrate and with a wall of a housing to separate channels. Liquid drops will be ejected by heating the heating elements. Since liquid may flow linearly from the inlet to the separate channels in accordance with the present invention, smooth flow promotes evacuation of bubbles through a nozzle, while cooling the heating element substrate with liquid flowing along with the substrate. The present invention provides thereby stable printing with high speed, continuous ejection (printing) of liquid drops.
