Collision Avoidance System A collision avoidance system uses proximity sensors and/or cameras to detect objects in a vehicle’s path. It measures the distance between the vehicle and any object in its path and automatically controls the braking and engine speed to prevent an accident. Systems may also have emergency steering or rear automatic braking to help avoid collisions. The collision avoidance system may also be referred to as an automatic emergency braking system (AEBS) or a forward collision warning (FCW) system. Blind Spot Warning System A blind spot warning system uses proximity sensors to detect vehicles to the rear in adjacent lanes while driving, Figure 38‑10. The proximity sensors are typi- cally in the rear bumper. The driver is typically alerted with lights in the side-view mirror. The lights will turn orange and/or flash until the vehicle is beyond the M2020/Shutterstock.com Figure 38-7. As of May of 2018, all vehicles sold in the United States must include backup cameras. Drivers can back up safely and prevent tragic accidents, such as backing over a child. This backup camera shows a panoramic view of the area behind the vehicle. It superimposes yellow lines to indicate the vehicle’s direction of travel. gunsan gimbanjang/Shutterstock.com Front camera Side camera Electronic control module Rear camera Side camera Video connection Display Dmitry Dven/Shutterstock.com Figure 38-8. Surround view camera systems use multiple cameras to produce a composite image of the objects surrounding a vehicle.

Adaptive cruise control uses multiple sensors to detect the distance of the car ahead of the driver’s vehicle. If the driver is too close to the leading vehicle, the system will first adjust the vehicle’s speed and apply the brakes if necessary.
