AUTOMOTIVE IN EMBEDDED SYSTEM

1. EMBEDDED
SYSTEM
BY
N.R.VETRIVEL
UNIT-”5”
TOPIC: AUTOMOTIVE EMBEDDED SYSTEM

2. Automotive Embedded System are the one where
electronics take control over the mechanical
system.
 Wiper control.
 Mirror control.
 Airbag control.
 ABS(Antilock Braking System).

3. ECU(Electronic Control Unit)
It built around microcontroller ,DSP or Hybrid
of two is called ECU.
•First automotive fuel injection was
introduced byVolkswagen(1968).
Types of ECU:
1. High Speed Electronic Control Unit (HECU).
2. Low Speed ElectronicControl Unit (LECU).

4. High Speed Electronic Control Unit
--Fast Response.
1.ABS
2.Fuel Injection.
3.Steering Control
4.Transmission control unit
5.Engine Control

5. Low Speed Electronic control unit
Slow Response
1.Audio controller.
2.Door glass controls.
3.Wiper control
4.Seat control system.
5.Sun roof control unit.

6. Automotive Communication Buses
By making use of serial bus communication.
Types:
1.Controller Area Network (CAN)
2.Local Interconnect Network (LIN).

7. Controller Area Network(CAN)
 It is proposed by Robert bosch.
 “pioneer” Embedded solution
provider.
 It supports Medium & High speed data
transfer.
 Employed in safety system like Air bag
control, Engine control, GPS.

8. Local Interconnect Network(LIN)
 Single slave communication interface.
 Low speed up to 20kbps.
 Employed in Mirror control,AC control,Seat
position control.

9. Key players of the
Automotive Embedded market
1. Silicon providers -> Chips (i.e.)
Microcontroller,ADC, DAC, IC chips etc.

10. 2. Solution provider->BOSCH,DENCO,
INFOSYS.
3.Tools & Platform providers->Embedded
software and embedded hardware.
