Abstract: When a non-operable notification is output from any of a plurality of operating vehicles, an operation schedule creator creates a substitute vehicle introduction operation schedule based on planned stopping times and a target velocity determined by a normal operation schedule, as an operation schedule to be provided, to each of operating vehicles other than a non-operable vehicle which has output the non-operable notification, when the operating vehicle passes an operation schedule updating location for a first time after the non-operable notification is output.

Abstract: A receiver includes a large diameter main body portion, and an intermediate member side small diameter portion. A wall thickness of the intermediate member side small diameter portion is smaller than a wall thickness of the main body portion. As a result, heat capacity of the intermediate member side small diameter portion is reduced. As a result, it is possible to complete brazing between the intermediate member side small diameter portion and the intermediate member, at the same time as brazing among tanks, tubes, and fins. A desiccant enclosed in a flexible bag can be taken in and out through the intermediate member side small diameter portion.

The body includes a first inlet, a second inlet, and outlets including a first outlet. The switcher is capable of switching a passage configuration to a state in which a fluid that has flowed in from the first inlet flows out of either one of the outlets and a state in which the fluid that has flowed in from the second inlet flows out of either one of the outlets.

Abstract: In a driving control device that controls a driving system for a vehicle, a voltage monitoring unit determines an abnormality in voltage detection and a current monitoring unit determines that power is supplied to the battery when a battery has a current value on a charge side relative to a predetermined value. When the voltage monitoring unit determines that the voltage detection is abnormal, a running control unit controls a rotating electric machine in such a manner that the vehicle is brought in a fail-safe running state. A power supply control unit controls a power supply source to be in a power supply prohibition state. A switch control unit cuts off a switch, in a case where it is determined that power is supplied to the battery during the power supply prohibition state of the power supply source.

Abstract: An accelerator pedal system includes a pedal lever, a lock mechanism, an actuator, and an ECU. The lock mechanism can restrict the operation of the pedal lever. The actuator switches between a locked state in which the operation of the pedal lever is restricted by the lock mechanism and an unlocked state in which the operation of the pedal lever is not restricted. The ECU includes a lock operation determination unit and an actuator control unit. The lock operation determination unit resumes the locked state by the drive of the actuator after a release from the locked state due to the step-on operation of the pedal lever during the automatic drive control in the locked state, when (i) the automatic drive control is continued or (ii) a resuming of the automatic drive control is detected.

Abstract: A voltage detection apparatus includes a capacitor and first and second differential voltage detection circuits.

A fault determining unit determines a fault in the first or second differential voltage detection circuit based on a first voltage that is inputted from a first input terminal and a second voltage that is inputted from the second input terminal. A voltage output circuit is supplied a third reference voltage from a third output terminal between the first output terminal and the second output terminal, and outputs a third voltage to a third input terminal between the first input terminal and the second input terminal.

Abstract: A controller includes first and second setting sections. The first setting section sets a first duty-cycle, which is a percentage of a switch-on time period of a drive switch in one switching-cycle, by peak current-mode control to control a reactor current to be a current-command value generated based on an AC-voltage value. The second setting section sets a second duty-cycle, which is the percentage of the switch-on time period of the drive switch in one switching-cycle, by average-current-mode control to control an average value of the reactor current to be the current-command value. The controller operates the drive switch at the first duty-cycle when an absolute value of the AC-voltage value is equal to or more than a threshold less than an amplitude of the AC-voltage value, and operates the drive switch at the second duty-cycle when the absolute value of the AC-voltage value is less than the threshold.

In the first energization process, electric current is supplied from the first storage battery to the second storage battery via the first inverter, at least one of the armature windings and the second inverter. In the second energization process, electric current is supplied from the second storage battery to the first storage battery via the second inverter, at least one of the armature windings and the first inverter.

The main detection element is arranged at a position closer to the detection center than the sub detection element. The package is arranged at a position where a center of the package deviates from the detection center.

Abstract: In an abnormality detection device for detecting whether there is an abnormality in either of an optical sensor and a camera that are used to detect objects around a vehicle, a correlation value calculation unit calculates a correlation value between at least one of a reflection intensity image that is detected by the optical sensor emitting light toward surroundings of the vehicle and then receiving reflected light of emitted light and a background light image that is detected by the optical sensor receiving light from the surroundings of the vehicle while the optical sensor is emitting no light, and a captured image of the surroundings from the camera. An abnormality determination unit is configured to, in response to the correlation value calculated by the correlation value calculation unit being out of a predefined range, determine that there is an abnormality in either of the optical sensor and the camera.

Abstract: In response to confirmation request from an onboard terminal in a state where updated data after start of a temporary road change is available, a map update server distributes the updated data and instructs the onboard terminal to temporarily use the updated data. In response to the confirmation request in a state where the updated data after end of a temporary road change is available, the server instructs the onboard terminal to use the updated data from before the start of the temporary road change. In response to being instructed to temporarily use the updated data, the terminal uses the updated data that has been distributed. In response to being instructed to use the updated data from before the start of a temporary road change, the terminal temporarily uses the updated data by using map data from before the start of the temporary road change instead of the updated data.
