|Applicants:||HITACHI AUTOMOTIVE SYSTEMS, LTD.
|Title:||ONBOARD NETWORK DEVICE|
Illicit data transferred over an onboard network can be detected by means of a simple configuration without increasing the data processing load in an onboard device, even during complicated control such as automatic driving. An onboard network device 1 has a communication monitoring unit 2, a status acquisition unit 3, and a determination method setting unit 4. The communication monitoring unit 2 monitors data passing through a network 6, and changes the communication monitoring method in accordance with the status of the automobile acquired by the status acquisition unit. The communication monitoring unit 2 has a communication determination unit 7, and determines, according to the determination method set in the determination method setting unit 4, whether or not there are any abnormalities in the data passing through the onboard network device 1 via the network 6.
