DEVELOPMENT OF A FLEET MANAGEMENT SYSTEM FOR AN OFF-HIGHWAY VEHICLE V.Jagannathan 1.a* , B.Jaiganesh 2.b & S.Sudarsanam 3.c Mahindra & Mahindra Limited, Mahindra Research Valley, Mahindra World City, Anjur PO, TN, India Corresponding author Email- V.JAGANNATHAN@mahindra.com Managing an off-highway vehicle fleet during validation is a challenging task. Complexity is acquainted when more than 100 vehicles with different horse power (hp) & with different product configuration working across India and other parts of countries. Traditionally, a tractor validation involves data collection such as usage hours (Hour meter reading on cluster), locations etc. which are recorded in spread sheet and updated to the respective project owners on daily basis through mail communications. A manual recording and consolidation of tractors validation status is prone to error, reiterative work, consumes more resource and effort. Moving towards digitalization, IT enabled system for updating the tractor validation status on daily basis was added with advantage of huge data storage capacity, history data retrieval and data access anytime & anywhere, a step ahead to traditional method but with few limitations of not knowing health of the system on real time basis. This paper proposes a fleet management system with a focus to provide tractor real-time location and remote monitoring of tractor performance data along with vehicle diagnostics monitoring systems. A Fleet Management System (FMS) architecture was designed and developed with a web-based solution, aimed at gathering the information of tractor's status and location in real-time. Geographic Information System (GIS) is embedded for understanding the exact position of the tractors in real-time. Geofencing technology was also incorporated for tracking tractor and ensuring that they remain in the predetermined boundaries. Latest technologies are embedded to the tractor for providing detailed equipment usage and health measures. Parameters like usage hours, locations, fuel consumption, engine temperature, oil pressure, engine speed in rpm, torque, and engine warning lights are monitored in real time basis. The combination of the GPS and GPRS provides continuous and Real-time tracking of data signals from the vehicle. Real time data is integrated and transmitted to a web server. This Fleet management system (FMS) had contributed less downtime by providing more statistics for creating better preventative, predictive maintenance strategies. Moreover, it has also improved test scheduling, tractor operating efficiency and effectiveness during field validation. This fleet data logging is remotely controlled via web-based application, saving time and increasing the reliability of the testing process. Limitations do exist in the operating areas, an off-road vehicles (Tractors) are generally deployed in very remote locations contrary to any on road vehicles (Cars and buses), hence network connectivity and loss of data is a concern. To overcome this limitation a logic written to the hardware in a such way that if GPRS has no signal in remote location, GPS data is still written to a file on the memory card inbuilt to the logger and this can be retrieved from the memory card anytime. A trigger is set for the system to push the data when logger comes to the GPRS zone again. An additional unique feature of the system is that it automatically sends daily reports updating on the latest fleet activity and fleet statistics. Our proposed FMS is a real time with an ability to handle more than 100 tractors with fast response. Integrated with data analytics for providing real time analysis upon big data, which simplify the strategy for faster decision making.
