Adaptive Cruise Control

Specific Objectives :

1-Explain principle of the adaptive cruise control and function.

2-Describe the components of adaptive cruise control system.

3-Demonstrate the advantages & Disadvantages

What is adaptive cruise control

How does ACC work

Adaptive cruise control that activates :automatically if

A) The vehicle is cruising above 40 MPH

B) At a steady state for more than 10 seconds

C) The user has enabled the auto set function

Components of an ACC system1 )Adaptive cruise control Module – That major function

of the adaptive cruise control module is to process the radar information and define whether a forward car is present.

2 )Engine Control Module – That essential function of the Engine Control Module to draw information from the adaptive cruise control

3 )Brake Control Module – That is an essential function of the Brake Control Module is to define car speed through each wheel and to slow the car via stratify the brakes when requested via the adaptive cruise control Module.

4 )Instrument Cluster – The main function of the Instrument Cluster is to remedy the Cruise switches and send their information to the adaptive cruise control and engine control modules.

5 )CAN – The observer area Network (CAN) is an automotive standard network that uses two wire bus to transfer and receive the data.

Main components of ACC Switches and pedals

Processor or mini computer

Sensor

Electronic vacuum actuator

location the components

Headway control unit

Millimeters-wave radar

Processing unit and stereo camera

•Monitor the engine load using a vacuum sensor to measure the intake manifold absolute pressure.

This vacuum sensor will help maintain intake manifold absolute pressure at a preset level.

Monitor the vehicles speed sensor and engine tachometer signal.
