Reference Design For A Smart Real-Time Vehicle Tracking System

Reference design for a smart vehicle tracking system based on GPS/GSM/GPRS. The reference design can predict accidents and car burglaries and share multiple data such as location, speed, time, etc. over GPRS to the web server application.

The STEVAL-IEG001V2 from STMicroelectronics is a smart vehicle tracking system reference design based on GPS/GSM/GPRS technology. The reference design allows developers to easily create a GPS/GSM/GPRS-based vehicle tracking system, by providing a complete hardware and software solution with a clear and easy-to-use interface. It uses the STM32F401RE microcontroller, which is a powerful 32-bit Arm Cortex-M4 MCU, and it also includes a GSM/GPRS modem and GPS receiver, as well as a range of other interfaces and peripherals.

This unit features a 3-axis accelerometer and yaw/pitch/roll gyroscope L3GD20. Reference design can senses car lift using the MEMS and thus predict vehicle theft. In case of vehicle crash (detected using MEMS), the vehicle status and location parameters are logged within the microSD card and the same information is sent to the admin by text message, thereby implementing black box functionality. The system consists of a vehicle unit (installed inside the vehicle) and a remote web server application where the vehicle status and movement data can be viewed in an intuitive way on the map.

Features of STEVAL-IEG001V2:

  • Real-time vehicle tracking through GPS/GSM/GPRS. Vehicle location co-ordinates acquired using a Telit GPS module and sent over GPRS to web server-based fleet tracking application
  • The vehicle states are defined as parked, in-journey, off journey and break
  • Vehicle location and status tracking on web-based GUI application using APIs by third-party map provider OpenStreetMap
  • Graphical display of information including vehicle status, location coordinates, speed, distance covered, GPS strength, GSM signal strength, time and date
  • Car lift alarm for anti-theft feature (sensed using MEMS)
  • Black box functionality: in case of vehicle crash (detected using MEMS), vehicle status and location parameters are stored in the microSD card and a text message is sent to the admin “Mobile Number” informing of the alarming situation.

This reference design has been tested by STMicroelectronics. It comes with required design resources such as Gerber files, schematics, BoM, etc. You can find additional data about the reference design on the company’s website. To read more about this reference design click here.
