Basic automatic headlights work through sensors that detect how much light is outside the vehicle. Most times, these sensors are located on the dash of the vehicle. The headlights turn on when the sensors detect a certain level of darkness.Know More
Adaptive headlights are one type of automatic headlight. Adaptive headlights rotate when the vehicle is turning so that the road in front of the driver is always well lit. They use sensors to detect the speed of the vehicle, how far the driver has turned the steering wheel and the yaw, or the rotation of the vehicle around a vertical axis. Some adaptive headlights also sense when the brightness of the headlights needs to be adjusted. Generally, the sensors in adaptive headlights do not turn on if they are not needed, such as if the vehicle is parked or in reverse.
There are limitations to automatic headlights. Sometimes they do not turn on during heavy rain or fog, as the light sensor still detects enough light. Automatic headlights do not immediately turn on in cases of sudden darkness, such as if the vehicle drives through a dark tunnel. In these cases, it is important for drivers to use their best judgment and manually turn on their headlights if needed.Learn more about Car Parts & Maintenance
A temperature sensor measures the hotness or coolness of an object. The sensor’s working base is the voltage that’s read across the diode. The temperature rises whenever the voltage increases. The sensor records any voltage drop between the transistor base and emitter. When the difference in voltage is amplified, the device generates an analogue signal that’s proportional to the temperature.Full Answer >
Central locking systems work through the use of a central computer in the car called a "body controller," which relays signals to the locks of the vehicle and monitors whether they are locked or unlocked. This system is a form of power door locks.Full Answer >
A muffler reduces the exhaust noise of a vehicle by blocking and reflecting sound waves. Inside the muffler is a series of baffled chambers and perforated barriers that break up the high-velocity sound waves as they flow through the device, reducing the overall noise level.Full Answer >
Automotive air conditioning works as a self-contained looping process within the vehicle that changes the state of the refrigerant to both a gas and liquid. A high- and low-pressure system completes the process and blows cool air to the vehicle's passenger cabin.Full Answer >
