Abstract

The various embodiments herein provide an automatic vehicle load monitoring system and navigation monitoring system. The system comprises a weight sensing device attached to a base of a vehicle, and wherein the weight sensing device is a load cell, a compression spring attached to the weight sensing device and to a suspension spring of the vehicle, a voltage conversion unit attached to the weight sensing device to convert an output resistance of the load cell into a voltage, an automatic vehicle location (AVL) system connected to the voltage conversion unit to receive the output voltage from the voltage conversion unit and a central server connected to the AVL to receive a vehicle location data and a voltage data for computing a vehicle load at an instant. The vehicle location data and the vehicle load at any instant is communicated simultaneously to a driver of the vehicle.
