Adaptive cruise control improves upon conventional cruise systems by not only maintaining a preset speed, but also by automatically keeping a safe distance between your car and the vehicle in front of it. Using forward-pointed sensors, cameras, or both, adaptive cruise control maintains your preset speed while constantly monitoring the vehicle in front of you. However, the kicker is, it automatically slows and accelerates to maintain a predetermined following distance. More sophisticated adaptive cruise control systems can bring your car to a full stop If necessary.
Check your car’s controls
If it has autonomous emergency braking, you car will stop if the vehicle in front of it suddenly stops. In icy conditions and when driving in fog, you need more control over your speed. It can also be dangerous in heavy rain when there’s a risk of aquaplaning. Before you start, make sure that you learn where all the controls are and what they do. It can be dangerous to fumble around with unfamiliar buttons while you’re driving. If the car in front suddenly speeds off, however, your car won’t routinely follow it.

Adaptive cruise control (ACC) is the latest type of cruise control that’s becoming widely available in cars. ACC maintains your speed but incorporates sensors to measure the distance to the car ahead. Once you set a distance, the ACC adjusts your speed to ensure you stay at that distance — usually a car length or two. Traffic jam assist is a type of adaptive cruise control that some cars have.
Capacitors Basics
If necessary, the system will bring your car to a complete stop. Some units employ a laser, while others use an optical system based on stereoscopic cameras. Regardless of the technology, ACC works day or night, but its abilities can be hampered by extreme conditions, such as heavy rain, fog, or snow. The system is made up of the steering wheel controls, an input from a speed signal, an output to hold the speed steady, and an output to shut the system off.
What is adaptive cruise control?
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. If it’s raining heavily or the road is icy, it’s best to turn off cruise control and rely on manual driving. However, it’s a tool designed to make the driver’s task easier and less stressful.
Wait for a moment when it’s appropriate to use cruise control before turning it on. Check that the road is clear, that weather conditions are good, and that you’re on a highway or a road where you won’t have to stop or change speed often. If conditions are right to use cruise control in your car, turn on the system.

For example, if you come up behind a slower moving car, the ACC will automatically slow your speed down to keep a safe distance from the car in front. If the car in front of you speeds off, the ACC won’t speed up to follow but will instead steadily increase your speed until it reaches the limit you’ve set. This is like a more advanced version of cruise control which users lasers, sensors or radar at the front of the car to detect other cars. There’s some evidence that cruise control can make your driving more fuel efficient. It can be hard to maintain a constant speed, so cruise control helps you to drive without constantly accelerating and decelerating. With adaptive cruise control, the vehicle will also automatically slow down and speed up to maintain a safe position in traffic.
Adaptive cruise control vs. standard cruise control
This also looks out for nearby hazards, such as pedestrians, cyclists and other motorists, whilst also reading road signs and detecting traffic lights. The bumper-mounted radar, which is already used in autonomous cruise control, looks out for vehicles in front of and behind the car. The earliest variants of cruise control were actually in use even before the creation of automobiles. The inventor and mechanical engineer James Watt developed a version as early as the 17th century, which allowed steam engines to maintain a constant speed up and down inclines. 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. It's pretty basic and doesn't have any fancy bells and whistles.
The result is that the closer the car gets to the desired speed, the slower it accelerates. Also, if you were on a steep enough hill, the car might not accelerate at all. Controlling the speed of a car is a classic application of control system theory. The cruise control system controls the speed of the car by adjusting the throttle position, so it needs sensors to tell it the speed and throttle position. It also needs to monitor the controls so it can tell what the desired speed is and when to disengage.
First, let's start with one of the most basic control systems you could have -- a proportional control. In the past 25 years, huge leaps in sophistication propelled cruise control to a point where some drivers may be confused by exactly what it is and how it works. Here, we will clear up any confusion about its functions, benefits, and limitations to help you on your car buying journey. Cruise control is one feature you’ll want from a good car for road trips and other frequent highway driving. It can not only potentially help you get better gas mileage but also make driving much more comfortable. This can be really useful in busy speed-limit zones so you can speed up and slow down with the flow of traffic without ever breaking the speed limit.
This is achieved by measuring the error – how fast your car is moving relative to the speed that’s been set on your cruise control system. Super Cruise is a next-level driver assistance feature available on certain GM vehicles. Your car’s Antilock Braking System works hand-in-hand with your cruise control system, and any fault with the ABS system will typically take your cruise control offline until it’s fixed.

Cruise control is what many Americans demand, owing to our extensive road network. As autonomous vehicles become more sophisticated, cruise control technology is evolving to support higher levels of automation. For example, some autonomous vehicles are equipped with advanced cruise control systems that can navigate complex traffic scenarios, merge onto highways, and even change lanes autonomously. It allows cars to talk to each other, coordinating their speeds to maintain a safe distance. It's like having a well-coordinated team of cars all working together to make the traffic flow smoother and reduce congestion.
We also wouldn’t advise you to use cruise control at night or if you’re feeling a bit tired. With less to do behind the wheel, there’s more danger that you’ll fall asleep. Different makes and models of cars may work in slightly different ways, but many vehicles will follow the same basic steps.
