Vehicles with front and rear cameras also provide visual warnings of obstacles. Cross Traffic Warning: A visual, audible, or haptic alert if an object is currently out of camera range, but appears to be moving into it. In addition to warnings and alerts, some collision avoidance systems assist drivers in mitigating imminent risks.
These systems will override the driver, changing the throttle of the vehicle or applying the brakes. The tools to inform these systems are similar to alerts, including radar, lasers, and cameras, however the response of the vehicle is more proactive.
Collision avoidance features that actively assist drivers include:. Adaptive Cruise Control: More preventative than reactive, these systems use radar or lasers to adjust your cruise control speed via throttle to maintain an appropriate distance from the vehicle in front of you.
Automatic Emergency Braking AEB : Brakes are automatically applied based on feedback from sensors in order to prevent a collision or minimize collision speed. Rear Automatic Emergency Braking: Brakes are automatically applied to prevent the vehicle from backing into an object using a cross-traffic monitoring system or sensors like radar or lasers. Pros Among the many benefits of CAS, this technology can make drivers safer by scanning the roadway for imminent danger.
Cons Inconsistency is one of the biggest disadvantages of collision avoidance systems because it is difficult for the technology to recognize every possible scenario that can happen on the road.

Get started today with a free estimate. A collision avoidance system CAS , sometimes referred to as a collision prevention system, can help you prevent or reduce the severity of a car collision. The system may use artificial intelligence AI , dash camera, and GPS technologies to help you identify an imminent collision. If a collision is about to occur, a CAS notifies you via sound, light, or both, so you can act quickly to prevent an accident.
If your vehicle gets too close to a car in front it, the forward collision prevention system alerts you about an impending crash.
A lane departure warning system notifies you if your car starts to drift out of its lane. In addition, a lane departure warning system can provide real-time blind-spot detection to reduce your risk of a blind-spot collision.
An automatic braking system automatically activates your car brakes if it senses an object near your vehicle. The system applies a small amount of braking power, and you can apply additional braking power as needed to slow down or stop your car. In doing so, adaptive cruise control helps you maintain a safe distance from the vehicle ahead of you. Rear automatic emergency braking uses a cross-traffic monitoring system, radar, or lasers to detect objects behind your car. ESC uses an onboard computer that monitors sensors across your vehicle that help manage wheel braking and acceleration.
Think about the questions below. If the pedestrian in front of you crosses the street, how will your forward collision warning system respond? My forward collision warning system may not detect the pedestrian as he crosses the street, meaning I would not receive a warning. I should never solely depend on my forward collision warning system, but should constantly scan the road ahead to watch for pedestrians and other hazards. Many forward collision warning systems struggle to detect vehicles ahead of you when driving through snow, rain or fog.
In these situations, your system may not be able to see through the falling snow. Similarly, your sensors may become covered by snow or ice during a storm, causing it to not function at all.
After a snowstorm, you come outside and see your car covered with snow. When clearing the snow off of my vehicle, I should always make sure to clear any snow on the vehicle to ensure sensors are clear.
This will allow the system to function appropriately. I should be especially mindful when using my forward collision warning system in these conditions, as emphasized by the Road Conditions challenge. Some forward collision warning systems, particularly those that are laser- or camera-based, may not function properly during situations with glare or low light, or when lighting changes drastically. In the image to the right, for example, your forward collision warning system may struggle to detect vehicles while driving through the tunnel, as well as when the lighting changes abruptly at either end.
Imagine yourself driving at dusk, as shown in the image to the right. Because of the high glare and overall low light conditions, my forward collision warning system may not be able to detect the vehicles in front of me, so I should be especially cautious and constantly scan the road ahead.
