ADAS (Advanced Driver Assistant Systems) are systems developed to simplify the driving process through various assistant tools. The features ADAS incorporates are designed to improve driver safety and are commonly incorporated in the driving experience through voice guidance and visual feedback. ADAS technology can detect some objects, do basic classification, alert the driver of hazardous road conditions, and in some cases, slow or stop the vehicle. This level of ADAS is great for things like blind spot monitoring, lane change assistance, and forward collision warnings. (ADAS can incorporate a larger range of systems than are described here).
Many newer vehicle are equipped with some type of ADAS. Some of the systems sensors may be attached to your “windshield”. Such as Rain/Light sensors and Forward Collision Alert cameras etc… The sensors/cameras on your “windshield” work with other sensors located around your vehicle to provide information to the onboard computer and driver. If one sensor is out of calibration it can cause others sensors in that array not to function as intended by the manufacturer.
