By real time tracking system, the vendor gets control to the transportation process and reduces risk to the drivers.

2) Environment-Friendly Operations

It is stated that an idling vehicle emits over 10 million tons of carbon dioxide into the air. Considering the strict transportation laws all over the world, the main objective of implementing the IOT automotive solution is to monitor the driver’s performance and monitor fuel utilization along with all standard features of fleet management.

Crossing the speed limit while driving has a harmful effect on the environment along with that it also causes excessive wear and tear and in addition to fuel costs. Implementing IOT technology in automotive industry, the company can get real-time automated alterations and can track driver’s behaviors, which is extremely helpful in minimizing objectionable behaviors.

3) Predictive & Preventive Maintenance

Predictive diagnostics solutions based on IoT technology for automotive are designed to notify the driver of any future breakdown or failure of some of the vehicular systems in advance. Predictive maintenance systems continuously monitor, collect, record, transfer, analyze and evaluate data from in-vehicle sensors – in sync with various vehicular parts – to keep track of the vehicle’s functional metrics. The vehicle’s sensors gather data like engine temperature, speed, acceleration, tire pressure, fuel level, engine-oil, brake fluid level, emissions, and other aspects and evaluate them against their ideal limit for the type of vehicle, and notifies the drivers or operators instantly in case of any discrepancy.

How does Predictive Maintenance for Automotive sector work?

Below are some of the benefits of predictive maintenance systems:
