Communication system, one or more servers, and a program for one or more servers

摘要

PROBLEM TO BE SOLVED: To add determination of real time property to a technology to cause one or more servers outside a vehicle to diagnose an on-vehicle device.SOLUTION: A communication system includes: a control device mounted on a vehicle together with an on-vehicle device which acquires and transmits inspection data necessary for diagnosing the on-vehicle device; and one or more servers installed outside the vehicle that receives the inspection data transmitted by the control device, and diagnoses the on-vehicle device by controlling an actuator mounted on the vehicle using the received inspection data. The one or more servers determine by state SB whether or not a time required for the communication between the control device and the one or more servers exceeds a predetermined reference value, and based on the determination that it exceeds the predetermined reference value, suspends the diagnosis of the on-vehicle device by transitioning from state SB to state SA.SELECTED DRAWING: Figure 13
