The document discusses the components and functions of an adaptive cruise control system. It explains that the adaptive cruise control module processes radar information to detect vehicles and define speed. The engine control module communicates with the adaptive cruise control module. The brake control module slows the vehicle when requested by applying brakes individually. The instrument cluster sends switch information to the modules. Questions at the end ask about the principle, components, advantages, disadvantages and features of adaptive cruise control.

2.  Come in time.
 Work in groups.
 Find out the lesson information.
 Respect others answers and opinions.
 Arrangement the classroom before you
departure.

5. 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

8. 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

9. 1) 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.

10. 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.

13.  Switches and pedals
 Processor or mini computer
 Sensor
 Electronic vacuum actuator
