  • Patent number: 10316780
    Abstract: A controller of an air-fuel-ratio sensor includes a control unit, a voltage-abnormality detecting unit, and a short-circuit-abnormality detecting unit. The control unit controls a current and a voltage of a gas sensor element through a plurality of terminals connected with the gas sensor element. The voltage-abnormality detecting unit changes, when at least one of voltages of the plurality of terminals is out of a predetermined range, a voltage level of an output voltage. The short-circuit-abnormality detecting unit causes, when the voltage level of the output voltage changes from a first voltage into a second voltage, a control unit to perform for a predetermined time a protective operation that suppresses currents from the control unit to the plurality of terminals, and detects, when the voltage level of the output voltage is the second voltage after the protective operation is released, a short-circuit abnormality.

  • Patent number: 10300911
    Abstract: A vehicle control apparatus that is mounted in a vehicle issues a warning to a driver of the vehicle to stop the vehicle in a case where the collision has occurred between the vehicle and an object. The vehicle control apparatus stops the vehicle regardless of an operation by the driver after issuing the warning to the driver, in a case where the vehicle is not detected to be stopped. Thus, while giving a priority on prompting the driver to voluntarily stop the vehicle, it is possible to prevent the driver from fleeing a scene of the accident or the like.

  • Patent number: 10296322
    Abstract: A controller according to an embodiment includes a main processing unit and a storage. The main processing unit shifts, when receiving an updating request of a control program during executing this control program, to program shifting through a restart in a state where a device power source is held. The program shifting starts an updating program for updating the control program instead of the control program. The storage is configured to be able to hold information while the device power source is held. The main processing unit causes the storage to store, before the restart, update requesting information indicating that the updating request is received, causes the storage to store a history of the restart, and performs a start determination on the updating program on the basis of the update requesting information and the history that are referred after the restart.

  • Patent number: 10227062
    Abstract: A water-droplet detecting apparatus according to an embodiment includes a setting unit, a first extraction unit, a second extraction unit, and a determination unit. The setting unit sets concentric circles having a center at arbitrary one point of a captured image of an image capturing unit. The first extraction unit extracts candidate pixels based on gradients of pixels on a circumference of each of the concentric circles. The candidate pixels are candidates for pixels that are estimated to indicate a water droplet adhered to the image capturing unit. The second extraction unit extracts one or more candidate circles based on the candidate pixels extracted by the first extraction unit. The one or more candidate circles are candidates for circles that indicate a shape of the water droplet. The determination unit determines whether or not the water droplet is adhered based on an extraction result of the second extraction unit.

  • Patent number: 10223384
    Abstract: A drive recorder sends to a server a moving image file showing a situation of surroundings of vehicle in a moment at which large acceleration occurred. The server determines, based on moving image file, whether or not to prohibit from being overwritten moving image file showing surroundings of vehicle in a moment at which an event occurred. Based on a determination result determined by the server, the drive recorder prohibits from being overwritten an image data set showing the moment 1) at which the event occurred or 2) optionally before and/or after the event occurred including the moment at which the event occurred. Thus, the drive recorder can surely prohibit the image data set to be prohibited from being overwritten. Moreover, it is possible to effectively use a storage area of a memory by allowing overwriting image data set that does not necessarily need to be prohibited from being overwritten.
