Abstract

An on-board network system includes a plurality of controllers connected to a bus, a detecting unit that detects an error that occurs, a measuring unit that measures a degree of error occurrence detected by the detecting unit, and a communication controller that reduces a communication speed and a communication data amount of at least one of the controllers from a first speed and a first data amount to a second speed and a second data amount, when the error occurrence degree becomes equal to or larger than a first degree. The communication controller reduces the communication speed and the communication data amount, such that a first communication time it takes for data to be transmitted at the first speed in the first data amount is longer than a second communication time it takes for data to be transmitted at the second speed in the second data amount.
