Claim:
1. A vehicle monitoring system, comprising: a first sensor, wherein the first sensor comprises a speed sensor for detecting a vehicle speed; a second sensor for detecting the speed limit of the road the vehicle is on; a head unit, wherein the head unit comprises a screen; at least one smart unit, wherein the smart unit comprises a processor, a transmitter, a receiver, a display and an input device; wherein the first sensor is capable of generating a first signal for the detected vehicle speed and then sending the first signal to the head unit; wherein the second sensor is capable of generating a second signal for the detected speed limit and then sending the second signal to the head unit; wherein the head unit is capable of receiving and analyzing the first signal and the second signal, and generating an analysis result, and then displaying a warning or sending the analysis result to the smart unit if the vehicle status is abnormal; wherein the head unit is capable of recording the analysis result in a log which is accessible to the smart unit and is sent to the smart unit periodically or in real-time; wherein the head unit is programmed to process different signals from respective sensors in a parallel manner; wherein the communication between the first sensor and the head unit takes place in real-time; wherein the communication between the second sensor and the head unit takes place in real-time; and wherein the smart unit is authorized by the head unit and capable of displaying the analysis result and the log in audio or visual format; wherein the head unit is configured to recognize whether the vehicle status is abnormal by comparing the first signal with a plurality of predetermined values or a plurality of standard values; wherein the predetermined values are set by the user; wherein the standard values are set by the second signal derived from the second sensor; wherein the head unit is capable of determining whether the vehicle is speeding by comparing the detected vehicle speed and the predetermined values or the standard values.
