1.0 INTRODUCTION Car’s wiper is a part of car to remove any item that suddenly appears on the front mirror. Every car in this world has a pair of wipers. Wiper has many types depends on the company that produces it. It also has its quality value, the more quality of the product the higher the price will be. Many components involves on it when install the wiper at car. Wiper can be produce by certain material. Almost all the wiper are create with alloy and rubber because this material can hold longer and corrosion resistance. How effective the existing wiper in the market? Nowadays, accident always happened in our country because of the careless from the driver itself. Sometimes technical problem also can lead to accident. One of the technical problems is occur during wet season. The accident will occur when the driver view had been blocked by the rain or snow hitting their windshield. This may give an effective effect to the driving itself. In our country the climate is hot and humid all along the year, so the road is at high risk during the rainy season. If we look back, there was no product in our local market that can keep all this remote controls in a place. Therefore, appear an idea to design a Rain Tracker Wiper Control. Figure 1: Rain Tracker Wiper Control 1 1.1 OBJECTIVE The objectives of this product are: 1. To automatically start or stop the wiper if it should be starts or stops by raindrop. 2. To automatically control the speed of wiper squeak when the windshield getting dry by raindrop. 3. To make sure the drive more safe & easier. 1.2 PROBLEM STATEMENT 1. If we look at the road the driver sometimes not alert with the raindrop. 2. Drivers sometimes face the different weather. So this product can help detect the size of raindrop either it was heavy rain. If there is no time to get much movement to adjust their car wiper as it is raining. 3. There are some driver that low ability that need a few or limits movement when conducting the wheel, this Rain Tracker will help this driving more safely and helpful. 4. Driver sometimes cannot expect what, where, or when the rain will stop. So they actually forget to turn off the wiper that still work on. This Rain Tracker was design to stop automatically if they were no raindrop on the windscreen. 5. Weather cannot be control so the risk of the driver to meet with rain is high. So if using the not quality front mirror in their car, sometimes the view are dim when the rain too heavy. 6. Wiper is sensitive part in the car component; if the speed of the wiper is not parallel with the flow of the rain maybe it can cause the problem to the wiper. 7. Only a wiper control to on the wiper, if the switch if broken it can cause a problem when raining. 2 1.3 SCOPE Our project scope will focus on to make sure these products are fully working automatically controlling the windscreen wiper. The function and the type of component are included. There are several cars which we will discuss in project which uses in our country. Only for common examples of the design and briefly discuss about the material and the installation, as there have many types of material use. The historical and the development of the design will not be mentioned in our research project. 1.4 THE DESIGN PROCESS Below is the steps process in designing the product: Figure 2: Flow of design process 3 Flow chart Background research Searching for information and data Investigate the system Analyze the system Develop design and functionality Submit the final draft report Chart 1: The flow of the process to generate the project 4 2.0 FUNCTION OF PRODUCT This Rain Tracker Wiper Control has many functions such as: To keep the driving safe and easier. - When the driver drives their car and suddenly raining, this Rain Tracker can work on the spot when its sensor detects the raindrop. Can automatically control the speed of wiper squeak depend on the speed of rain. - The speed of raindrop can be unexpected, but if using Rain Tracker the sensor can detect the speed of rain drop and control the speed of wiper depend on the raindrop. Can help the drivers reduce their movement when driving. - When the wiper works automatically, the driver can concentrate on driving. Can be install to all type of car that having a terrible change of weather at their country. - This product can be installing in any types of car and not for certain type only. It means either Toyota, Honda, Nissan or any brand of car can use this product. Can make customer easy to continue their journey. - The driver can drive properly without thinking that they will forget to open the wiper if raining because the Rain Tracker can help them to switch on the wiper automatically. It also can decorate the back wind screen wiper. - This product not just helps to detect the raindrop but also can be functioned as a decoration to the car to look more modern with new concept. 5 2.1 INSTALLATION INSTRUCTION 1. GET A WIRING DIAGRAM FOR YOUR VEHICLE - If the instructions refer to either the HSS or GSS diagrams included with this manual, write specific vehicle wire colors on the diagram. If the instructions call for external components, they are usually included in the accessory kit. 2. TEST THE EXISTING WIPER SYSTEM - Make sure that the existing wiper system works in off, intermittent (if so equipped), slow, and fast modes of operation, and the wash motor works. 3. LOCATE THE WIPER SYSTEM PARTS - You will likely need to remove access panels. You can often trace wires from the switch or motor, or listen for clicking relays when the wiper system is in intermittent mode. 4. MOUNT THE RAIN TRACKER ACTIVATION / SENSITIVITY SWITCH - The supplied round activation switch turns the Rain Tracker on to default sensitivity. Mount the switch before you connect the switch wires to the Rain Tracker. Select a mounting location in a dash knock-out panel, or in an under-dash panel (available at auto parts store.) To mount the round activation switch, drill a hole (5/8 inch or ¾ inch depending on switch model supplied) and file the hole slightly larger until the switch can press in appropriately. File a locating notch as needed. Other styles of (SINGLE POLE) switches are available from Radio Shack and other suppliers. 6 5. INSTALL THE RAIN TRACKER INTERFACE MODULE - Make sure the location you select for the module will not conflict with the operation of any equipment, such as accelerator or brake cables. Use the wiring diagram as a guide in connecting the Rain Tracker interface module into the existing wiper system. - Connect the wires as shown in the diagram. If the diagram requires that you make a chassis ground connection, find a suitable metal frame member and screw, and make sure that it is free of paint. Bad grounds are the most common problems we encounter when troubleshooting Rain Tracker installations. - Plug in the interface connector so that its locking ramp engages the locking ramp on the interface module. 6. INSTALL THE SENSOR - Select a coupler mounting location within the area swept by the wipers, and out of the shade band. Just below the mirror mount is usually a good location. Tip: mark the location with a piece of masking tape on the outside of the windshield, and stand back from the vehicle to make sure the mark is level. Prime the sensor mounting location with isopropyl alcohol. Figure 3: Installation sensor process 7 7. INSTALL THE SENSOR CABLE - Connect one end of the sensor cable to the sensor, and route the cable under the head liner and down the vehicle's trim to connect it to the interface module. 8. SECURE THE INTERFACE MODULE - Use cable ties to secure the interface module to a bracket or convenient location. Reinstall access panels as needed. 9. TEST THE RAIN TRACKER SYSTEM WITH A SPRAY BOTTLE OR GARDEN HOSE - Turn the ignition to accessory mode. Use the wiper control switch to verify that all manual modes (off, slow, fast, and wash) work. Put the system in Rain Tracker mode by turning on the activation switch. Spray a light mist at the sensor and verify that the Rain Tracker runs the wipers in intermittent mode. Spray more water and confirm operation in steady slow and fast speeds. Figure 4: Wiring diagram 8 2.2 TROUBLESHOOTING 2.2.1 SENSOR SENSITIVITY ISSUES i) WIPES TOO MUCH - Make sure the Rain Tracker is in an area that is being completely cleared by the wipers. Sometimes at the edges of wipe patterns the wipers leave a film of water, and this will make the Rain Tracker wipe too much. Also, worn wiper blades will cause excessive follow-up wipes. ii) WILL NOT SENSE RAIN OR WIPES TOO LITTLE - Make sure the Rain Tracker coupler is properly mounted to the windshield, and is reasonably free of air bubbles. Note that the Rain Tracker will not see through the red tape- the coupler must be mounted to the glass. Also, the glass just over the sensor should be free from windshield treatments. 2.2.2 VEHICLE INTERFACE ISSUES Check Ground First - Check that the Rain Tracker is getting a good ground. Use a multi-meter to verify that the resistance between the black ground wire on the Rain Tracker interface connector and the vehicle chassis is less than two ohms.
