Adaptive cruise control or in short ACC is a term most of you might have heard of it various times but not all of you might know what it is or what it does. To clarify Adaptive cruise control is a combination of cameras, sensors, radars and much more sensitive electronics that together form a system to assist the vehicle to maintain a safe following distance and speed from the vehicle in front without the need for human interaction. In this article we will be going through various sub-topics like how does Adaptive cruise control works, what are its merits and demerits, does Adaptive cruise control comes in the category of level 1 ADAS or level 2 ADAS?

Adaptive cruise control other names

Adaptive cruise control is advertised by automobile companies with many different names to make it look more unique than that used in other cars, some of these names include

  • Radar cruise control
  • Automatic cruise control

How Adaptive cruise control works?

As mentioned earlier ACC uses a combination of sensors, cameras and even radar to measure the distance of your car from the one ahead of you. By the use of any of the devices mentioned above the system regularly monitors the distance between both the cars and tries to maintain a constant number between the two, which is achieved by the application of brakes and accelerator. In case the distance between the car starts increasing the system senses it and to compensate acceleration is provided to the car, however, in case of closing in on the gap between the cars, the system applies brakes whose intensity depends on the speed on which the distance between the two is decreasing.

Merits of an ACC

Although the Merits aren’t many or some sort of a life changer but are quite significant. The first being that this system allows the driver to take a small break from focusing on the road and relax his/her eyes and mind from the road ahead, second merit is that it allows a smooth flow of traffic on highways and also reduces the chances of accidents.

Demerits of an ACC

The demerits of ACC are also quite similar in number with the first being that this system isn’t fully autonomous and still requires human attention behind the wheels to get the best results, in case of any problem where the system fails to come up with any proper solution, it will display a warning sign on your dashboard including a beep sound to get your attention. The second demerit is that the system fails to work properly in case of various weather conditions such as snow, rain and fog and can even fail in closed spaces like tunnels.

Difference between Cruise control and Adaptive Cruise control

Some of you might think that Cruise control is the older version of the Adaptive Cruise control system, which in a sense is partially true, as originally this system wasn’t designed for cars in mind. Originally the cruise control system was designed for ships and aeroplanes where the pilots or captain leave their ships or aeroplanes at a predefined speed as there isn’t much of a chance of collision in mid-air or a vast ocean. However, when this technology came to cars, where moving at a fixed speed isn’t always ideal as the car Infront of you might reduce the speed at any time causing accidents, if not paid attention. So, to overcome this problem Adaptive Cruise control was developed which is only feasible on roads.
