CHAPTER 6: CONCLUSIONS
After a period of implementation of the graduation project, the group has completed
the model of the Lighting, Door lock, Power window, Windshield wipers and washer
system of Hyundai I10/ Xcent 2018 and repair the training model Automotive power
window and power door lock system. During the process of researching and implementing
the topic, the group has absorbed a volume of specialized knowledge about body electrical
systems, thereby helping the members better understand about the electrical systems of
modern vehicles. The group has achieved some results as follows:
+ Building the theoretical basis of the model of the door lock, power window,
lighting, wiper and washer system.
+ Build a model about automotive body electrical system and repair - upgrade a
model.
+ Build practice sheets to help students practice about errors on the system.
Thereby, teachers can use the model for teaching, helping students in the later class
to have closer access to the body electrical systems of modern cars, closer to reality.
