Automotive Electronic Control Units (ECU) Solutions

Ans. In our 11+ years of automotive ECU software development journey, we have successfully delivered projects designed on some widely deployed microcontrollers:

Here’s a detailed list of MCUs, based on which we have delivered several automotive projects:

• TI Microchip NXP- Automotive Sun-roof System
• Renesas NXP MC Platform– Motor Control Systems
• ST Microelectronics– Automotive Sunroof System
• NXP MPC Micro Series– Electronic Power Steering (EPS) ECU
• Infineon – Battery Management System for Electric Vehicles, DC to DC Converter for Solar powered EV charger

Ans. First, we can custom-develop the Board Support Package (BSP) packaged with the all the low-level drivers and APIs to facilitate the integration.

If no customization is needed in the BSP software provided by the chip vendor, we can partner with you for the development of all the interfaces that may be required for the integration of application software.

If you wish to migrate your application software to a new microcontroller platform, we can also provide BSP customization/development and driver development support for this.

As part of the integration support, the following will also be the part of project deliverables

• Enhanced APIs to help the application get the required data from base software modules
• API documents, if the integration needs to be executed by your in-house team

Ans. Yes, we will provide in-vehicle network compliance tests for CAN or LIN. This test is performed w.r.t to a protocol parameter in order to test the system under stress conditions.

For instance, LIN will be communicated with 500 Kbps of data rate, a lot of signals will be passed simultaneously, and several error scenarios will be created in the testing tool. We will investigate the software and its behavior under such test conditions.

CAN/LIN Project Reference: We have partnered with one of our US based customer for CAN and LIN compliance testing of an automotive roofing system.

Based on the results of the test-case scenarios, our team was able to deliver a stable software solution. CAN/LIN compliance testing helped us to ensure that the software stack was tested to perform as expected, under all vehicle environments and operating conditions.

Ans. Yes. We have partnered with many customers for integration of third-party stack, with the existing application software and MCAL drivers.

If you have the third party stack and want us to develop a Bootloader based on the stack, our team has the required expertise to deliver the same.

We can also develop the low-level drivers required to facilitate the integration

These are the components that we offer as an integration service, following are the details:

• MCAL development and integration
• Communication Stack (UDS, Bootloader etc.) integration

Ans. We provide development support for a range of automotive control units. Some of the automotive ECUs for which we have partnered with OEMs and suppliers are:

• Body Control Module
• Motor Controller- DC Motor, BLDC Motor, Induction Motor
• Electric Vehicle ECUs – Battery Management System,
• ECUs for Adaptive Lighting systems

Ans. The following are the details of the control algorithm that we can develop for the motor control system. We can provide support for both open and closed loop control systems:

• Field Oriented Control Algorithm: can be developed by manual coding or by Model Based Development (MBD) with MATLAB
• Proportional Integral (PI) Algorithm
• Proportional Integral Derivative Algorithm for closed-loop control system using MATLAB
• Current Regulation Algorithm
• Speed Control Regulation Algorithm
• Soft Start/ Soft Stop Algorithm for controlled motor starting and stopping

Ans. We are fully equipped to handle any 3rd party tool-specific unit testing requirements. The 3rd party tools, for which we have provided support to our partners, include RTRT, PolySpace, MxDev tool, QAC and more.
