CHAPTER 1: OVERVIEW OF THE TOPIC 1.1 Reason for choosing the topic

In an era where the automotive industry is growing and changing constantly, mechanical control systems are gradually being replaced by electrical controls

Therefore, our group implements the topic: DESIGN AND MANUFACTURE OF

TEACHING MODEL OF THE MITSUBISHI TRITON 2019 LIGHTING, DOOR LOCK CONTROL, WIPER AND WASHER SYSTEMS to contribute to improving the

understanding of automotive electronic and Electrical systems

1.2 Research purposes

In order to understand the structure and operating principle of the lighting, door lock control, wiper and washer systems

Design and making model

Design troubleshooting, practice sheets then apply it to tasks such as diagnosing, maintaining, and repairing cars in the future

With the goal of DESIGNING AND MANUFACTURING OF TEACHING MODEL

OF THE MITSUBISHI TRITON 2019 LIGHTING, DOOR LOCK, WIPER AND WASHER SYSTEM, the main research method is the method of document research Then, we design

and manufacture the model base on the knowledge that we study to meet the initial objectives

CHAPTER 2: THEORETICAL BASIS 2.1 Overview of the car door lock system

Today, with the continuous development of society in general and the automobile industry in particular, cars have become one of the essential and valuable assets for people Therefore, ensuring the safety and property of customers is a task as well as a challenge for the manufacturer, and an in-vehicle system whose main function is to ensure the safety and property of the user that is the door lock system And along with the increasingly modern development of the automobile, the door lock system also undergoes a process of evolution from the most rudimentary structure to the most perfect, modern level, from mechanical control to remote control, by smart key even from a smartphone

2.1.1 Classification

Mechanical door lock system: It is a popular door lock system on old cars, this type

is completely controlled by a mechanical transmission mechanism, there are 2 common types of opening/locking of the mechanical door lock system: Pin the key to the door lock

on the outside of the car or pull the knob on the inside of the car door

Figure 2 1: Mechanical door lock system

Electric door lock system using a switch inside the car: This type uses an electric system and electric motors to open and close the car door, controlled through the push buttons to unlock the door at the driver's door

Figure 2 2: Electric door lock system inside the car

Door lock system using remote key: Remote control door locking system is a system that sends remote control signals from the remote controller in combination with the key

to control the opening and closing of the car when near or far from the vehicle

Figure 2 3: Door lock system with remote key

Door lock system using a smartphone: This system is very modern, comfortable, and safe, just a sensor attached to the vehicle can be wirelessly connected to a personal mobile phone for identification The user can even use his voice to open the car door This

is the newest system available today and may be widely used in the future

Figure 2 4: Door lock system with mobile application

2.1.2 Overview of the remoted control door lock system

Remote door lock control system is a system that when operating will send signals from the remote control attached to the key to lock/unlock the car doors even when standing far away from the vehicle When the door control signal receiver receives the signal emitted from the remote controller, it sends the control signal to the controller The controller will send the signal to the combination relay then controls the motor to lock/unlock door based

on the received signal This system was first developed by Siemens in 1995 and introduced

by Mercedes-Benz in the S-class sedan “Keyless Go” in 1997

The combination relay will control the door lock motors based on the lock signal or unlock In addition to this function, the combination relay also has a return function, repeat

function, alarm function, auto-lock function and other functions Depending on the type of vehicle, people design to suit the needs of users

2.1.3 Functions of remote door lock control system

2.1.3.1 Function to lock/unlock all doors on the vehicle

Use the remote control to press the lock or unlock button to lock/unlock 1 or all car doors, this is a function applied on most modern models with remote control by electricity

2.1.3.2 Two-step unlock function

Press the unlock button for the first time to open the driver's door then press it a second time within 3 seconds to unlock all the remaining doors This function is applied

on some high-end cars with the purpose of avoiding the situation when the driver unlocks all the doors, the bad guy takes advantage of the opportunity to enter the back door of the car with bad intentions

2.1.3.3 Feedback or snooze function

The hazard warning light (turn signal) will flash once when locked and flash twice when unlocking to indicate that the vehicle lock/unlock function has been successfully activated Some models of cars, if the user forgets the key in the car, the car will make a sound warning the driver to avoid forgetting the key in the car

2.1.3.4 Function to check the operation of the remote controller

When pressing on the remoted control switch to lock/unlock the car door or the luggage compartment door, the remoted control operation indicator light comes on to inform indicates that the system is active, however, if the battery is depleted this light will not bright This function is also to recognize the battery capacity of the lock to diagnose the failure of the remoted control door lock system

2.1.3.5 Function to open the luggage compartment door

Press and hold the luggage compartment open button on the remote control for about

1 second to open the luggage compartment

2.1.3.6 Power window opening and closing function

If the vehicle's lock/unlock function is pressed and held for 2.5 seconds or longer without the key in the vehicle, all doors will open/close as long as the switch is held and stop when released

Some cars don't have this function

2.1.3.7 Alarm function

Finding a car in a large parking lot will be very difficult if it is at night with limited visibility and light, which will make it difficult for drivers Therefore, the designer integrates an alarm function, if holding the car open switch of the remote control for longer

than about 2 to 3 seconds will activate the alarm system (the headlights and turn signals will flash)

2.1.3.8 Function to turn on the lights in the car

The lights in the car will come on for about 15 seconds at the same time as when the doors are unlocked with the remoted control switch

2.1.3.9 Auto lock function

If no doors are opened within a period of 30 seconds after they are unlocked by the remoted control switch, all doors will be locked

2.1.3.10 Repeat function

If one door is not locked according to the control of the remote controller, the controller will issue a lock signal after 1 second

2.1.3.11 The function of warning the car door is ajar

If any one of the vehicle's doors is left open or ajar, the pressing the door lock switch

of the remote control will make the door lock buzzer sound for about 10 seconds

2.1.3.12 Protection function

The rotation code changes according to the fixed law used as part of the radio waves transmitted from the remote control The remoted control receiver that receives the vehicle's control signal stores the rotation code when receiving the signal from the remote control and uses this code to compare with the vehicle's code when receiving the next radio signal from the remote control thereby increasing protection

To prevent the car door from being unlocked by operating the control switch (manual operation on the vehicle) with a bar or equivalent through the gap between the window glass and the door frame when the window is open, perform the following operation: This door locking operation with the remote control (including automatic locking) will confirm the door lock protection function and remove the manual door opening function

2.1.3.13 Remote controller identification code registration function

This function facilitates the registration of the four remote control identifiers into the EEFROM built into the remoted control receiver In case you want to record the identification code, check the registration code number, or lose the key, the identification codes can be deleted and the remoted control function does not work

Some car models allow receiving up to 8 identification codes

2.1.4 Requirement

The remoted control door lock system needs to:

+ Meet all operations in all weather conditions

+ Accurate, durable, fast operation, and high safety and reliability

+ Easy to use and convenient for all ages

+ Easy inspection and replacement, convenient installation and disassembly + Convenient repair service

2.1.5 Classification of wireless door lock control system

Classify by control key layout:

+ Type of key combined with the control key: the type of key and control is integrated into one, this type is compact and simple, suitable for those who like neatness However, this type has disadvantages that if the key is damaged or the remote control is damaged, the whole set of keys must be replaced

+ Type key and control remote separated: this type of private car key and separate control key are often found on cars There is no wireless lock function and an extra remote control is installed, so there is an extra key to control This type of use has the disadvantage that you have to carry both keys with you, so it will be difficult if you forget one of them

+ Type control with the smart key: this type of system is equipped with the Immobilizer system, the button start system is a system that interferes with the engine control system to prevent the engine from starting when the key is not correct This type has high safety and protection, often used on new and high-end cars The system uses an additional shortwave for two-way communication with the vehicle, and key code recognition to control the opening of the engine starting systems

Classified according to the structure of the actuator structure:

+ Door lock system using motor mounted with actuator: This is the original of system and is widely used on new cars today The motor is directly controlled and is built into the actuator

+ Door lock system using door mouse: used on older cars without a remoted control system Lock/Unlock is controlled through the door gun, which indirectly affects the actuator
