The Car Information Central Control System (CICCS) proposed in this paper aims at automatic control of Car Functional Control Systems (CFCSs) in the course of driving and lessening thus the dependence on driver's ability. At certain conditions, it centralizes the control over all kinds of existing CFCSs according to facts, driver's experience and intentions, so that increases car's active safety, comfort and global performance. This paper mainly discusses the architecture and principle of monitoring system in CICCS and its possible insertion to the currently existing networked control system.
