    摘要: A controller of a power supply control is configured to: in response to a failure of a main power supply being detected, execute a fail-safe control in which a connector is interrupted and electric power from a backup power supply is supplied to a second load; in response to a state value indicating a charging state of the backup power supply decreasing to a first threshold during the fail-safe control, execute an advance notice process for giving a user advance notice that a vehicle will be stopped; and in response to the state value decreasing to a second threshold which is smaller than the first threshold and which indicates a safety limit of the backup power supply, execute a power supply stop process for stopping supply of the electric power from the backup power supply.

    摘要: An image processing apparatus includes a controller configured to: (i) perform image recognition of a camera image to identify a signal region in which a traffic light exists in the camera image, the traffic light including an arrow light; (ii) identify a candidate region of the signal region, the candidate region satisfying (a) a first condition related to a color component of the arrow light and (b) a second condition related to a luminance component of the arrow light; and (iii) determine that the arrow light of the traffic light is turned on when a size of the candidate region that has been identified is smaller than a predetermined size.

    摘要: An image processing apparatus includes a controller that determines a light color of a traffic light from a camera image. The controller is configured to: (i) perform image recognition of the camera image to identify a signal region in which the traffic light exists in the camera image; (ii) set a plurality of different spatial intervals between detectors that detect pixels in the signal region having respective color components of respective lights included in the traffic light; (iii) generate a plurality of feature maps indicating a feature amount for an arrangement pattern of each of the respective color components based on detections of the signal region by the detectors using the plurality of different spatial intervals; and (iv) determine the light color of the traffic light based on the plurality of feature maps.

    摘要: A power source supervisory apparatus is provided with a connection path that connects between a first path and a second path, an inter-path switch SW provided on the connection path, a current limiting element disposed to be in series to the inter-path switch SW on the connection path enabling a conduction from a first path side to a second path side under a current limiting state and obstructing conduction from the second path side to the first path side, a supervisory unit that supervises occurrence of a voltage drop on the first path in a state where the inter-switch is closed, and a switch operation unit that opens the inter-path switch SW when the supervisory unit determines that a voltage drop occurs on the first path.

    摘要: A power supply control device includes: a connection device provided in an inter-system line that connects a first system and a second system; and a controller configured to control the connection device. The controller is configured to control the connection device to cut off the inter-system line in response to a power supply failure of the first system or the second system being detected, execute a confirmation process for confirming a failed system based on changes in voltages of the first system and the second system in a first period, and execute, in a case where the failed system cannot be confirmed in the confirmation process, an estimation process for estimating, as an abnormal system, a system with a greater possibility to be abnormal, based on changes in voltages of the first system and the second system in a second period longer than the first period.
