Telematics Gateway is a vehicle diagnostics system that allows users to monitor the key parameters of a vehicle from anywhere. Parameters such as location, working duration, engine performance, engine parameters need to be continuously monitored to prevent failures of such vehicles and extend the life of the vehicle.

With such off-road vehicles such as forklifts, cranes often leased out by manufacturers and often used for long hours in extreme working conditions, it is important for the owners to monitor their location and the parameters to effectively control the usage. Heavy-duty and off-road vehicles are used in large industrial spaces such as power plants, manufacturing units, construction sites with rough environmental and operating conditions, which makes them vulnerable to sudden failures and frequent breakdowns.

iWave introduced the gateway to cater to such rugged applications with a wide range of input interfaces:

  • 4 CAN Interfaces (CAN FD / HS CAN / LS CAN)
  • RS232
  • RS485
  • Analog and Digital Inputs
  • Automotive Ethernet

Integrated with a cellular 4G Modem and various other wireless connectivity options such as Wi-Fi and Bluetooth, the telematics gateway enables data transfer from the vehicles to the cloud platforms. Through Bluetooth, you can also configure the gateway as an Electronic Logging Device and connect to the driver’s phone to monitor the driving time and safety.

The data collected through the CAN bus, sensors, and other data parameters can be collected on the gateway and parsed onto an IoT Cloud Platform for further data analytics and modeling. Integrated with a powerful NXP i.MX 8 application processor with an internal memory of 8GB, the gateway also provisions for data storage in regions of no connectivity.

The gateway is integrated with the J1939 protocol for compatibility with heavy-duty vehicles and commercial trucks. The J1939 standard was standardized by the SAE, creating a uniform language on the CAN bus across the industry. This standard includes the digital annex (DA) which defines thousands of signals that could be used on the CAN bus, a subset of which are for EV-specific signals (such as high voltage, battery state of charge, vehicle charging status, and more).

The protocol support allows the Telematics Gateway to retrieve diagnostics information and real-time data from the vehicle’s interconnected ECU system offering the following key advantages:

• Easy access to diagnostics data for quick detection and troubleshooting of failures

• Remotely access efficiency and critical statuses of machines

• Ensure vehicle uptime with preventive /predictive maintenance

• Immediately notify negligent use, damage, and attempt of theft

Manufacturers and asset owners have a need to remotely monitor their assets on the field while gaining valuable insights from the cloud platform to determine the occurrence of any failure and take preventive actions to reduce the time of such assets. This can help manufacturers schedule preventive maintenance visits, acquire spare parts and other inventory, and allocate the right technician for efficient service, effectively increasing customer satisfaction and loyalty, while reducing costs.

The Telematics Gateway also encompasses 9 axis sensors and temperature sensors that can enable applications such as E-Call, Driver behavior analysis, Idling time, and other key features that can enhance the experience. Ruggedized Telematics Gateway is designed to operate in harsh environments and conditions like strong vibrations, extreme temperatures, and wet or dusty conditions.

Few reasons why a Telematics Gateway is necessary for owners of heavy-duty trucks and off-road vehicles:

• Increased customer satisfaction through fewer breakdowns and better diagnostics

• Reduced fuel, maintenance, and operating costs

• Predict emergency breakdowns and service time with simpler dispute handling
