With an increased demand for advanced analytics in CAN-based vehicles and a growing requirement for analytics on the edge, iWave has developed a proprietary ISO 15765 stack, enabling a simple and customizable API for handling diagnostics data over the ISO 15765 CAN network. ISO 15765 is an international standard and is the most widely used communication protocol in passenger and commercial vehicles since 2008. The protocol defines exactly how messages are exchanged in a vehicle’s interconnected ECU system.
The ISO 15765 stack developed by IWave, based on the ANSI C source code inherently supports all the specifications of ISO 15765 protocol, in addition to the extended four variations of ISO 15765-4 CAN. The stack supports both 29-bit and 11-bit CAN identifiers with standard baud rates of 250 kbps and 500 kbps, allowing the device to interpret all ISO 15765 standard messages from Vehicle ECU. The stack effectively determines the underlying ISO 15765-4 CAN be supported by the vehicle and initiates communication to receive and decode the data frames.
We enable full customization of the stack, integrating customer-specified feature sets and fine-tuning to meet end application requirements. Our comprehensive software development solutions involving protocol stack development, integration, optimized configuration tuning, and application development ensures faster deployment and time to market of the OBD II solution.
With the ISO 15765 protocol stack, the OBD II device can communicate directly with the vehicle and retrieve critical parameters specified by the manufacturer. Parameters such as speed, engine data, and emission data obtained in the form of Diagnostic Trouble Codes (DTC) are decoded and sent to customer-specified Cloud-based applications for analysis. Any rare occurrences /defects can be easily detected by analyzing the codes, thereby enabling efficiency in the vehicle’s remote management and overall performance.
The following are the key features of OBD II ISO 15765 CAN Stack:
In addition to the ISO 15765 protocol stack, the iWave OBD II device supports the SAE J1939 protocol stack allowing high-speed communication and diagnostics of data from heavy-duty vehicles.
