Control signal networks in vehicles using dedicated cables such as twisted wires or fiber optics cables have been built for communicating between electronic control units (ECUs). However, there are problems such as the increase of the weight of the cable harness and the difficulty to insure the reliability of the complicated network architectures. Therefore, communication systems using in-vehicle power lines have been investigated. In our previous work, we proposed an impulse detection method by using two-state hidden Markovian-Gaussian noise model for noise on in-vehicle power line. However, the simulation results showed that the proposed method has low accuracy with the impulse detection when there are no impulses in observed noise sequences. In this manuscript, we propose information criteria to decide whether impulses are included in the noise sequences or not statistically and show that the proposed criteria improve the impulse detection accuracy by computer simulations. |
