PROBLEM TO BE SOLVED: To acquire information needed for wake estimation from an on-vehicle LAN even if a protocol of the on-vehicle LAN is previously unknown.SOLUTION: A wake estimation device 10 comprises a positioning operation unit 11, a wheel speed detection unit 12 and a wake operation unit 13. The positioning operation unit 11 calculates the GPS speed of a vehicle on the basis of an observation amount obtained from a GPS. The wheel speed detection unit 12 detects vehicle information in correlation with the GPS speed as wheel speed from vehicle information flowing in the on-vehicle LAN. The wake operation unit 13 calculates a wake of a vehicle on the basis of the observation amount and the wheel speed.SELECTED DRAWING: Figure 1 |
