Development of Network Connectivity Interface APIs for 3-Wheeler Vehicle Control Unit

About the Customer:

The client is a prominent Electric Vehicle 3-Wheeler Original Equipment Manufacturer (OEM) based in India. As part of their continuous efforts to enhance the performance of their EV fleet, the client needed a robust and efficient solution to optimize the network connectivity and reduce runtime delays in their Vehicle Control Unit.

Business Challenges:

The client’s existing Vehicle Control Unit implementation was experiencing latency issues in network connectivity, which affected the overall performance of their 3-wheeler EVs. These delays in communication, coupled with network recovery challenges, were critical bottlenecks that needed to be addressed in real-time.

The client required a solution that would not only reduce time latency but also handle network errors efficiently and ensure smooth network recovery during runtime. A reliable, scalable, and time-efficient solution was paramount to ensuring optimal performance.

Embitel’s Solution:

Embitel Technologies addressed these challenges by developing network connectivity interface APIs specifically designed for the 3-wheeler VCU. Our approach focused on the following key areas:

  1. Network Recovery and Error Handling: We implemented a robust solution to handle network recovery and error management dynamically during runtime. This ensured that any network disruptions or failures were managed swiftly, minimizing downtime and optimizing system performance.
  2. AT Command Integration: The solution incorporated an AT command table, with AT commands being managed using a state machine. This non-blocking approach ensured efficient communication between the system and the network, reducing latency.
  3. Defined Error Codes: To enhance error management, we defined specific error codes that allowed the system to identify and respond to network issues quickly and effectively.
  4. Optimized Runtime Delay: Through careful design and implementation, we successfully reduced runtime delays, ensuring smoother network operations for the VCU. This was a critical improvement, significantly enhancing the client’s EV control system performance.
