Automotive Embedded Systems
Objective of Course :
The behavior of today’s automobile is a product of the embedded systems that control every aspect of its behavior from engine to navigation to interior temperature.
This course addresses modeling and implementation of advanced technology automotive engines for improved fuel economy and emissions, and improvements in systems engineering processes for the design of automotive embedded systems.
The student completing the course shall be very highly competent in the automotive domain trained for the latest technologies. They will have a thorough understanding of all the design and system constraints in the domain of work.
Orientation for the Automotive Mechanics :
Intent: To make the students completely aware of the different components of the automotive- Engine, Drivetrain, Suspension, Steering, Brakes, Instrumentation, Electric/ Electronics, Motion Control, Comfort (ergonomics), Infotainment
System approach to control systems :
Intent: Defining the behavior of the sensors and actuators in terms of time and frequency response and the design considerations in open loop and close loop systems.
Interfacing to the real world: Sensors and transducers:
- Classification of sensors – position, speed, pressure etc. on basis of their measuring variables and principle.
- Cover the major sensors-
- Position – fuel level, steering wheel angle, Ultra sonic, ranging radar.
- Acceleration/ Speed- Hall-effect phase, Piezo electric, inductive type sensors
- Pressure- micro mechanical, high pressure sensors
- Gas sensors – air quality, two-step lambda oxygen sensor, broad-band lambda oxygen sensor
- Temperature Sensors
- Software: sensing, sampling and algorithms
- Drives and Motors
Embedded Systems design :
- 8/16/32 bit Microcontrollers,
- RTOS- uCos-II, Vx Works
Protocols :
CAN, LIN, FlexRay and all the other technologies used around these like Bluetooth and USB
Testing Automotive software:
Intent: to orient students to the process of automotive testing- hardware, software- blackbox and whitebox testing on a load test box that shall be part of Institute infrastructure.
Mode: Assignments based. Students will design and complete their test cases and get evaluated.
Standards:
NIST, MISRA C, J1939, introduction to Flexray,Need and standards shall be covered in detail.
Model Based design and testing
Intent : The current trend of industry is its shift towards model based designing. Students will have training to do modeling on Matlab/ Simulink/ Labview and testing on same.
Case Study:
Current auto trends ABS(Antilock Braking system), Electronic steering, X-by-Wire, auto park feature (and more can be added)
This shall not be a separate topic but will be carried along in the curriculum. But student can be evaluated on any one topic of their interest.
Special Hardware/ Software Requirements:
- ECU (Electronic/ Engine Control Unit)
- Test box with input pots and sensors
- Automotive controllers: 16 bit controllers like MSP430, HCS12 series and 32 bit series like C2000 series.
- MATLAB/ Simulink software
- Certain sensor boards shall be available for testing/ project purpose.
- SAE India membership
