摘要： An analog-to-digital conversion system includes: a first conversion device configured to communicate with a first analog-to-digital converter configured to convert a first analog signal into a first digital signal; a second conversion device configured to communicate with a second analog-to-digital converter configured to convert a second analog signal into a second digital signal; a first reference low power supply; and a second reference low power supply. The first conversion device is configured to correct the first digital signal, based on a variation amount of a second reference low voltage or a second reference low current. The second conversion device is configured to correct the second digital signal, based on a variation amount of a first reference low voltage or a first reference low current.

摘要： An abnormality detection system configured to detect abnormal communication includes a first electronic control unit, a plurality of second electronic control units, a plurality of connector connection portions, and a processor. The connector connection portions are provided on a communication path between the first electronic control unit and the second electronic control units. Each connector connection portion includes a first connector portion and a second connector portion. The processor is configured to determine that, when abnormal communication occurs, one of the connector connection portions that is experiencing abnormal communication with all the second electronic control units connected to the second connector portion and that includes the second connector portion connected to the largest number of second electronic control units is abnormal.
