3. FAQs | Electronic Control Unit
Q1. Can you share your team’s experience with different microcontrollers for
automotive ECU development?
Ans: We have delivered several automotive ECU design projects, based on a
wide range of microcontrollers, during our 12+ years of automotive product
engineering services journey.
Here’s a list of all MCUs, along with the use case, with which our team has
hands-on experience:
• TI Microchip NXP- Automotive Sun-roof System
• NXP MPC Micro Series– Electronic Power Steering (EPS) ECU
• Renesas NXP MC Platform– Motor Control Systems
• Infineon – Battery Management System for Electric Vehicles, DC to DC
Converter for Solar powered EV charger
• ST Microelectronics– Automotive Sunroof System
Q2. How can your team support us for integration of an application software
to an existing microcontroller platform?
Ans. We offer multi-faceted support that starts with Board Support Package
(BSP) development. We will partner with you to develop all the low-level
drivers and APIs required for the integration.
If you already have a BSP provided by the chip vendor, we can help you with
the necessary BSP customizations (if any) and also develop all the interfaces
needed for integration of the application software with the micro-controller
platform.
As part of the integration support, the project deliverables will consist of:
• APIs to help the application fetch the required data from base software
modules (BSW)
• API documents, to help your in-house team execute the integration

Q3. Can Embitel provide CAN/LIN compliance testing services?
Ans: Yes, our automotive ECU development services also include in-vehicle
network compliance tests for LIN and CAN.
The system is tested under stress conditions to check its stability.
For example, we will send data at 500 Kbps through LIN or send multiple
signals simultaneously. Many such error scenarios will be created in the
testing tool and software’s behavior will be investigated under these stress
conditions.
Project Reference: We performed CAN and LIN compliance testing of an
automotive roofing system for one of our US based customer.
The result of the test-case scenarios helped our team to deliver a stable
software solution. We could also ensure that the software stack performed
as expected, under all vehicle environments and operating conditions.
Q4. Can you help us integrate 3rd party stacks (eg. Vector Tool based
software stacks) with existing application software and low-level drivers?
Ans: Yes, we can provide support for integration of 3rd party stacks with
MCAL Layer and application software. Following components are offered as
part of integration service:
• Communication Stack (UDS, Bootloader etc.) integration
• MCAL development and integration

Q5. For what kind of automotive ECUs can you provide development support
for?
Ans. We provide support for development of a wide range of automotive
control units. Enlisted below are a few automotive ECUs for which we have
partnered with OEMs and suppliers:
• Body Control Module
• Motor Controller- DC Motor, BLDC Motor, Induction Motor
• Electric Vehicle ECUs – Battery Management System,
• ECUs for Adaptive Lighting systems
Q6. Which control algorithm software have you developed for the Motor
Control system?
Ans. Embitel has the experience and expertise on a plethora of control
algorithms for the motor control system. We develop algorithms for both open
and closed loop control systems:
Have a look at some of the software we have developed for motor control
systems:
• Field Oriented Control (FOC) Algorithm: Developed by both manual coding
or Model Based Development (MBD) with MATLAB
• Proportional Integral (PI) Algorithm
• Speed Control Regulation Algorithm
• Proportional Integral Derivative (PID) Algorithm for closed-loop control
system using MATLAB
• Soft Start/ Soft Stop Algorithm for controlled motor starting and stopping
• Software Start/Stop Algorithm
• Current Regulation Algorithm

Q7. Does Embitel provide support for tool-specific testing services?
Ans. Yes, we have the expertise in handling any 3rd party tool-specific unit
testing requirements. The 3rd party tools that we have provided support for,
include QAC, RTRT, MxDev tool, PolySpace, and more.
Q8. Can you provide support for HMI development and other PC utility tools
development for vehicle diagnostics and ECU re-programming applications?
Ans. Yes, we do possess all the required skill-set for development of PC based
interface software.
We have developed Human Machine Interface (HMI), configuration tools,
mobile apps, PC utility tools to help our customers manage ECU
reprogramming and vehicle diagnostics applications
HMI Project Reference: We developed a configuration tool for a customer to
create codes for thousands of signals in a CAN DBC. If done manually, it would
have taken 30-40 days to complete this task. However, it took just a few
minutes to complete the same task, using our configuration tool.
Q9. Is calibration protocol support provided as part of ECU software
development services?
Ans. Yes, Calibration protocol support for both XCP and CCP based calibrations
are provided. In addition, we also provide UDS based vehicle diagnostics
calibration.
