In Learn How Windshield Wipers Function (Part 1), I have discussed the inner workings of a windshield wiper. For the second part, I will
- Typically, cars follow the same suit, and the design will have two blades moving together.
- For it to clean effectively, one swivels from the driver’s side of the car, and the second blade swivels from the middle. This is referred to as the Tandem System, and it is designed to keep foreign elements away from the driver’s point of view.
- However, for some car manufacturers like Mercedes, these brands use only one wiper that will cover the entire window. This system is called the Single Arm, and it is designed for an adequate coverage. Remember, this is more complex than the dual-wiper systems. Some cars are installed with a single wiper in the middle of the windshield.
- Next, let’s talk about the wiper controls. Generally, you can choose from the following: low speed, high speed, and an intermittent setting. If you choose either low or high speed, the electric motor will continually run. However, in the intermittent setting, the wipers will temporarily stop in between each wipe. For most cars, there’s just one intermittent setting. Meanwhile, other vehicles may include 10 different settings that you can set in any interval.
- Wiper settings can get a little too complicated. Because if it is too fast, the windshield becomes too dry and the wipers will make a squeaking sound. If the wiper is too slow, your view will filled with snow or raindrops.
- Moreover, you also consider that the water hitting your windshield will vary as the car accelerates and slows. You have to be attentive to make sure that the wipers are properly working depending on the situation. That’s why automakers have come up with a solution with the invention of the rain-sensing wiper.
- Manufacturers have tried to remove the wiper controls through the detection of rain vibrations. Some even use technology that will stop raindrops to form. Thus, there’s NO need to wipe your windows. However, these inventions have problems too, and they never materialized.
- There is a new wiper system that does a wonderful job of detecting water on the windshield is a rain sensor system. Typically, the sensor is installed in the interior part of the windshield, which is close to the rearview mirror.
- The sensor will emit an infrared light to the windshield. If the windshield is dry, the light will just bounce back. If water is present, the infrared lights will reflect to other directions. The wetter the windshield, the less infrared light will bounce back to the sensor.
- This kind of system is usually found on numerous General Motors cars, such as the Cadillac models. It can be switched off in case you need to wash or repair your car.
Wiper blades are essential to keep your auto glass any elements and to avoid distractions while you drive. This was discussed on Why Windshield Wipers Are Essential to Driving.
