Overall, the future of cruise control technology holds promise for creating a more seamless and enjoyable driving experience, with a focus on safety, comfort, and sustainability. So, if the car in front of you slows down, you'll need to step in and adjust your speed manually. This trusty system comes standard on most cars and is great for saving some fuel on those long road trips. Today, drivers can choose from a range of cruise control systems, each with its own unique features and functionalities.
Adaptive Cruise Control
If that car slows down, ACC slows your car down to keep a safe distance. Of course, as with any technology, there are some tips and considerations to keep in mind when using cruise control. First and foremost, always stay attentive and be ready to take control of the vehicle when necessary. Cruise-control is fantastic, but it doesn’t replace our responsibility as drivers.
Reduces Fatigue
The invention of cruise control can be traced back to the late 1940s and early 1950s, when engineer Ralph Teetor developed the first-speed control system. This innovative feature was designed to help drivers maintain a steady speed, reduce fatigue while driving, and improve fuel efficiency. Over the years, cruise control technology has undergone significant advancements, leading to the development of sophisticated systems like adaptive cruise control. Well, it depends on the road and your driving style but Generally speaking, yes it does help. If you’re on a flat highway with little traffic, cruise-control can keep your speed steady and avoid unnecessary acceleration and braking which can result in an average of 7-14% increased fuel economy. But if you’re on a hilly or curvy road, or in heavy traffic, cruise control can actually waste more fuel by trying to maintain a constant speed.

Speed Settings
Tapping the knob in the opposite direction will decelerate the vehicle. As a safety feature, the cruise control system will disengage as soon as you hit the brake pedal. Cruise-control is a feature found in some vehicles that allows the driver to maintain a constant speed without needing to keep their foot on the accelerator.
The 77-GHz Autocruise radar system made by TRW has a forward-looking range of up to 492 feet (150 meters), and operates at vehicle speeds ranging from 18.6 miles per hour (30 kph) to 111 mph (180 kph). Delphi's 76-GHz system can also detect objects as far away as 492 feet, and operates at speeds as low as 20 mph (32 kph). This factor helps the cruise control respond quickly to changes, such as hills. If the car in front suddenly speeds off, however, your car won’t routinely follow it. Instead, the ACC system will hold the pre-set speed until you change it, or it catches up with another vehicle.

That dream came true, and today, Karl covers everything from model reviews to features and how-to guides, while he has represented CarBuzz at global launches for models like the Lexus RZ and Audi SQ8. Before buying a particular model with ACC, it's worth going for an extended test drive to ascertain if the feature improves your driving experience. Notably, a laser-based sensor can struggle during storms or other periods of low visibility.
By now, you may have picked up on a potential drawback of cruise control — keeping a steady speed is harder to do (and possibly dangerous) when there are other drivers in front of you. It's always a good idea to consult your owner's manual for guidance on how to use cruise control. As with many vehicle functions like switching on lights, operating the ventilation system, or even using the indicator, each automaker does things slightly differently. You will set your desired speed as well as the gap you'd like to maintain from the preceding vehicle.
Adaptive Cruise Control (ACC)
The cruise control system controls the speed of your car the same way you do -- by adjusting the throttle position. But cruise control actuates the throttle valve by a cable connected to an actuator, instead of by pressing a pedal. The throttle valve controls the power and speed of the engine by limiting how much air the engine takes in (see How Fuel Injection Systems Work for more details).
From grinding and rattling to thumping and squealing, you can learn how to decode... Whether you're on a camping trip or need a rest far from home, these cars have enough interior space and comfort for a decent snooze. Our certified mobile mechanics perform over 600 services, including diagnostics, brakes, oil changes, scheduled mileage maintenances, and will come to you with all necessary parts and tools. Surprisingly, the most common "failure" is the system being turned off. If the cruise control is not operating for you, check that you haven’t turned it off. Keep yourself tuned in to the Indian automotive scene via Twitter, Youtube or RSS feeds.
Some vehicles do have the ability to apply the brakes, and cars with adaptive cruise control usually have this function built-in. As you approach your desired speed, your throttle will slow down, which helps keep your speed at the correct setting on your cruise control system. The driver must manually bring the vehicle up to speed and use a button to set the cruise control to the current speed. If you’re driving too close to the car in front, it will warn you in two stages. First, it will alert you with visual and acoustic signals, and then with a short braking jolt. Some units employ a laser, while others use an optical system based on stereoscopic cameras.
The cruise control system actually has a lot of functions other than controlling the speed of your car. For instance, the cruise control pictured below can accelerate or decelerate the car by 1 mph with the tap of a button. There are also several important safety features -- the cruise control will disengage as soon as you hit the brake pedal, and it won't engage at speeds less than 25 mph (40 kph). Adaptive cruise control is a more advanced technology that enables you to set a specific speed while the system automatically reads the traffic ahead and keeps your car at a safe following distance. With cruise control engaged, there's generally a "Set" button which locks in your current speed, so you can remove your foot from the accelerator.
This provides comfort and can help reduce driver fatigue when driving long distances on the highway. This feature allows drivers to adjust the vehicle speed easily, so they don’t have to constantly press the accelerator pedal. This is very convenient when driving long distances on relatively straight toll roads or highways. It’s important to remember that cruise control is not a substitute for attentive driving. Drivers should always remain aware of their surroundings and be ready to take control of the vehicle at any time.
Intelligent cruise control goes even further, using artificial intelligence to learn the driver’s behaviour and adjust the speed of the vehicle before the driver takes action. Stop-and-go cruise control is ideal for use in heavy traffic and can bring the vehicle to a complete stop if necessary, while speed limiters are designed to limit the maximum speed of the vehicle. Each type of cruise control system has its own advantages and disadvantages, and drivers should choose the one that best suits their needs. The main buttons are set, coast, accelerate, cancel, on, and off, and some new cars have maximum and minimum speed buttons as well. Speed limiters can be installed in vehicles as a safety feature, particularly in commercial vehicles like trucks and buses.
Cruise control as we know it today was invented in the late 1940s, when the idea of using an electrically-controlled device that could manipulate road speeds and adjust the throttle accordingly was conceived. One of the main advantages of using cruise control is improved fuel efficiency. By maintaining a constant speed, cruise control helps reduce fuel consumption, leading to better gas mileage. Rapid acceleration and deceleration, on the other hand, can lead to increased fuel consumption. Now, if conventional cruise control is your old reliable friend, then Adaptive Cruise Control (ACC) is like that friend's tech-savvy younger cousin. ACC isn't just maintaining your set speed, it's also keeping an eye on the car in front of you.
