OBD GPS Tracker

 

Objective: The client wanted to develop a small low cost device that could plug into the OBD connector of any post 1996 vehicle. Once installed the device would provide geo-tracking and automatically call 911 in the event of an accident or panic alarm by the operator.

 

Result: Our role was to work closely with the client's engineering team and be responsible for software development for the embedded controller. Having a through understanding of both the hardware and software requirements, we were able to identify hardware/software tradeoffs and quantify the potential effect on the total system performance.

 

Device that plugs into vehicle OBD port and includes GPS & GSM.Building on our past experience with TI's ARM 9 processor product line and the TI DSP/BIOS RTOS software suite, Original Technology was able to quickly bring up a multi-tasking environment on the TI AM1806 Sitara processor and develop interface drivers for the GSM, GPS, OBD, Audio, accelerometer, and other custom peripherals. These peripherals used a combination of USART, I2C, SPI, I2S, and high speed parallel interfaces. In addition the AM1806 two PRU's were used to offload high speed I/O functions and only interrupt the application when a complete packet of data was transferred.

 

By combining a mixture of C and assembly and incorporating code exported from MATLAB, the multi-tasking software was able to automatically detect a crash event, categorize the severity of the event, contact 911, and report—not only the location of the vehicle but the vehicle type and the severity of the crash.

 

 

Our Mission is to provide innovative solutions and quality products to our clients, while  providing them with the tools necessary for their success.
