Cruise Control In Cars Explained And How To Safely Use It LOOP
Table Of Content
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.

The driving style makes a lot of difference in this hybrid vehicle.
Imagine getting all sorts of excited to go on a long road trip that you’ve always dreamed of taking with your best buddies. The road is literally straight for hundreds of kilometers, and the thought of driving for 4-5 hours straight tires you out before you even get behind the wheel. Many cars use actuators powered by engine vacuum to open and close the throttle. These systems use a small, electronically-controlled valve to regulate the vacuum in a diaphragm.
Automotive Electronics Explained
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.
How to set cruise control
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 moment you do that, you will realize that your car gives you an ample amount of luxury, great overall mileage, a comfortable ride and a nice command on a highway. I remember, last month I went on the same route, and I got a mileage of 14.5 km/l via the same vehicle while this time we got around 19 km/l. A PID control system uses these three factors -- proportional, integral and derivative, calculating each individually and adding them to get the throttle position.
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.

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.
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.

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.
Moreover, on rough or loose terrain, the system may struggle to maintain control. Another drawback is that relying on cruise control can encourage drivers to pay less attention to the road, increasing the risk of accidents. Adaptive cruise control is just a preview of the technology being developed by both companies.

This feature allows you to maintain a constant speed even when you’re not pressing the accelerator. Moreover, it can aid in preventing speeding and improving fuel efficiency by minimizing unnecessary acceleration and braking. The system uses sensors and radar to detect the distance between the driver’s car and the vehicle ahead. If the vehicle ahead slows down or stops, the ACC system automatically applies the brakes to slow down or stop the car, maintaining a safe distance. When the road clears or the vehicle ahead moves faster, the ACC system accelerates the car to the driver’s set speed or the maximum speed limit.
