Vehicle monitoring vehicle monitoring system and method

The present invention discloses a vehicle monitoring system and method, the system comprising a vehicle and a cloud server, wherein the vehicle includes: a relative position detecting means for detecting a vehicle between a sprung mass of the structural member and the unsprung mass structural member relative position and generates a relative position signal; vehicle wireless communication device; alarm devices; control means, the control means transmits the relative position signal to a cloud server in real time by the vehicle wireless communication device, and receives the determination result cloud server feedback, and when the judgment result is bad when the road or the vehicle needs maintenance, the control means alarm; cloud server for recording the relative position of the vehicle transmitting the signal, and generates a relative position between the structural member and the mass of the mass of unsprung structure - time curve, and based on the curve is determined whether the road is bad road and / or vehicle maintenance needs. The invention can dynamically monitor the condition of the car, help to improve driving safety and extend the life of the vehicle.
