Windshield Information

The Windshield

Today’s windshields are a safety device just like seat belts and airbags. Windshields are normally made of AS1 laminated safety glass and two layers of heat treated glass with a strong PVB lamination film layer between them. This gives the windshield its strength and integrity needed for safety in modern windshields that can contribute up to 30% of the  vehicle’s roof integrity. They are typically installed by a bonding procedure to the pinch weld with urethane, or locked in by a rubber gasket. Motorbike windscreens are often made of a strong high-impact acrylic sheet and in some cases can actually have a higher impact tolerance than some glass.

Antennas

They have been using integrated circuitry in Windscreens for a while from just a wire in the lamination or printed directly on the frit band.  They are more common on rear or side quarter glass, but we still find some antennas on some of the windshields normally near the top of the glass.

Rain Sensor

Automatic WipersCars equipped with an automatic rain sensor will automatically trigger the windshield wipers and adjust their speed to conditions as necessary. Normally there is an AUTO function on your windshield wiper control stick if you have one. The first use was a device used to close the convertible top and raise the open windows to protect the interior of an automobile from rain and to support the automatic mode of windscreen wipers back in 1951.

Condensation Sensor

Condensation SensorCondensation Sensor is used to detect the presence of small amounts of water or ice on your windshield. Once it senses any condensation it is supposed to defrost the inside of your windshield automatically. These are normally located beside the rear view mirror in a small plastic housing with vents.

Lane Departure Warning System Cameras

Subaru Lane Departure Warning System SensorsLane departure warning system is a mechanism designed to warn the driver when the vehicle begins to move out of its lane (unless a turn signal is on in that direction) on highways. All the new technology that they are integrating into newer vehicles are supposed to help against distractions while helping to create a semi-autonomous vehicle. Because this system may also interact with your cruise control or other systems in the vehicle it is important that it is functioning properly for your safety.

Advanced driver-assistance system

Advanced driver-assistance system, or ADAS is the next step to fully autonomous driving. This system is fastest-growing segments in automotive electronics, especially on our Ontario highways. This system can rely on 5G data networks & multiple computer networking inputs, the vehicle takes all this information and makes thousands of calculations per second.
The system also controls;

• adaptive cruise control
• anti locking braking systems&lt
• Collision avoidance(Pre-crash system)
• Emergency brake assist (EBA)
• Intelligent speed adaptation
• Lane change assistance
• Lane departure warning system (LDWS)
• Traffic-sign recognition
• Vehicular communication systems

So it is easy to see how the ADAS is a safety concern if it is not calibrated properly after a windshield installation. The calibration can be done in shop and should be added to any windshield claim.
