  • Patent number: 11625927
    Abstract: An abnormality determination apparatus is mounted on a vehicle. A person is identified in a captured image acquired from a camera that captures a range including a driver seat of the vehicle. It is determined whether a person other than the driver of the vehicle is present in an operable range set as a range in which a steering wheel of the vehicle is enabled to be operated, based on a result from identifying a person. An abnormality process assuming that the driver of the vehicle is in an abnormal state is executed in response to determining that the person other than the driver is present in the operable range.

  • Patent number: 11626780
    Abstract: An electronic control device includes a plurality of control circuit units, a signal line, and a sneak-in suppression circuit. The plurality of control circuit units are connected to separate grounds, respectively. The signal line connects a first control circuit unit and a second control circuit unit. When a system is defined as a combination of a component and a ground corresponding to a control circuit unit, the sneak-in suppression circuit suppresses a sneak-in of electric power from the ground of one system (i.e., a subject system) to the other system connected by the signal line for preventing a cascading failure.

  • Patent number: 11624308
    Abstract: In a control apparatus, a heater adjuster performs a regeneration task of causing a heater to heat a sensing member of a particulate matter sensor to burn particulate matter deposited on the sensing member to thereby remove the particulate matter from the sensing member. The heater adjuster performs a deposition reduction task of maintaining, for a predetermined duration, a temperature of the sensing member at a deposition reduction temperature that reduces additional particulate-matter deposition on the sensing member. The predetermined duration is defined from completion of a regeneration task to a time when an environmental condition around the particulate matter sensor is determined to be stable. The heater adjuster stops the heater from heating the sensing member if a condition determiner determines that the environmental condition around the particulate matter sensor is stable.
