The document provides an overview of an engine control unit (ECU) and proposes features for a new low-cost ECU design project. An ECU uses a microprocessor to process sensor inputs and control parameters like fuel mixture, ignition timing, and other engine functions. Modern ECUs are sophisticated and expensive. The proposed new design aims to reduce costs by using an affordable ARM controller as the core system running on an RTOS kernel and combining CAN, FlexRay, and LIN networks to connect various sensors to monitor the car environment.

1. Engine Control Unit A condensed overview By Nikhil P Karthikeyan S Adarsh A

4. Wheel speed sensors and Throttle position sensors: Using rotary sensors and potentiometers.

5. Collision avoidance: This is achieved by obstacle detection sensors placed at appropriate places and detecting the potential obstacles.

6. Airbag deployment :Using crash sensors and by measuring the deceleration.

8. Hill climb assist: This system reduces the effort put in by the driver to control the brake and thus helps bring down the number of accidents on slope terrain as the driver concentrates only on clutch and accelerator . This can be done using IR sensors and gyrometer

10. Control of ignition timingAn ECU can adjust the exact timing of the spark (called ignition timing) to provide better power and economy.

12. The low cost LPC110X ARM controller acts as the core of the system running a RTOS Kernel.

13. We seek to use a combinational network of CAN, FLEXRAY and LIN for communication purposes

14. A complex network of sensors each interconnected to give a sense of the car environment
