The client, a trusted and reputed Automotive Tier-I Supplier of steering and driveline components, approached our Automotive Embedded Services team to resolve a very challenging embedded software development issue.
This hurdle was a grave one-it had the potential to derail the product roadmap of their futuristic Electronic Power Steering (EPS) system.
Here is the complete success story!
Our client had successfully embarked on their journey of designing an advanced Electronic Power Steering (EPS) system for Commercial vehicles. The following critical phases of product development lifecycle were already complete:
However, the customer encountered a major roadblock during software porting.Due to limited on-chip memory (RAM and ROM) of DsPIC 30F4011 platform, it became imperative for the customer to port highly-optimized embedded software to the EPS system.
Re-designing or changing the hardware platform would have impacted the bottomline of the project negatively, leading to substantial financial loss. Also, the DsPIC Microchip platform was best suited for the required EPS application, meaning that the only feasible resolution was an Optimized Embedded Software.
After several engineering workshops with the customer for understanding and analyzing the EPS system, Team Embitel was able to overcome the hurdle with the help of following solution:
Society of Automotive Engineers (SAE) J1939 is the vehicle bus recommended practice used for communication and diagnostics among vehicle components.
SAE J1939 is used in the commercial vehicle area for communication throughout the vehicle, with the physical layer defined in ISO 11898.
