When the car is going 55 mph, the throttle position opening will be only half of what it was before. 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.

Hyundai Sonata Adaptive Cruise Control Review: How Well Does the Tech Work?.

The Green Revolution on Rails: The Rise of Hybrid Electrical Systems in Train Design
In the picture above, you can see two cables connected to a pivot that moves the throttle valve. One cable comes from the accelerator pedal, and one from the actuator. Adaptive cruise control operates very similarly, but with the addition of more high-tech sensors and features. These sensors, which usually include a radar, will look ahead of your car to see what’s in front of it.

Cruise control technology plays a vital role in the development of autonomous vehicles, or self-driving cars. In autonomous vehicles, cruise control systems work together with other advanced driver assistance systems (ADAS) to enable the vehicle to operate without direct driver input. These systems include lane-keeping assist, automatic emergency braking, and collision avoidance systems. The cruise control system controls the speed of your car the same way you do – by adjusting the throttle (accelerator) position. However, cruise control engages the throttle valve by a cable connected to an actuator, rather than by pressing a pedal.
How To Set Cruise Control
All these sensors act perfectly in unison and obtain accurate data of the car’s location, thus providing additional safety. Using the input from the radar sensors, the computer unit measures the distance of the car ahead and calculates the speed relative to it. If there are multiple vehicles in the sensor’s field of coverage at the same time, it automatically selects which of the vehicles the system should track. The driver must manually bring the vehicle up to speed and use a button to set the cruise control to the current speed. However, there are several disadvantages to consider when using cruise control. In hazardous weather conditions, such as ice or snow, using cruise-control can be dangerous.
Adaptive Cruise Control
More advanced adaptive cruise control systems use camera or radar-based sensing to determine the traffic situation in front of your vehicle, and can automatically apply the brakes to maintain a pre-set following distance. 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. So, the best way to save gas is to use cruise control wisely and adjust your speed according to the road conditions.
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. Cruise control is a system within a vehicle that enables drivers to establish and sustain a specific speed without having to continuously press the accelerator pedal. The system uses electronic sensors to track the vehicle’s speed and automatically regulate the throttle and brakes to maintain the predetermined speed. Cruise controle is generally employed during extended trips on highways, where sustaining a constant speed can decrease driver tiredness and boost fuel economy. It is a common feature in modern automobiles, trucks, and other types of vehicles.

Cruise control, especially adaptive cruise control, is a great and convenient feature in our cars. This system – together with the integral factor of your PID system – ensures that you have all the acceleration you need to maintain the perfect speed. Together, these three factors are behind the entire cruise control process and form the basis for all modern cruise control systems. 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. In many cases with modern cars, it’s generally easier and more cost effective to just opt for a unit equipped with cruise control from the factory.
How Does My Car Accelerate When Using Cruise Control?
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. 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. Picture it like a synchronized dance on the highway, where every car knows its place and keeps the right distance. Imagine a future where traffic jams could be a thing of the past.
A wheel alignment makes sure your tires contact the road in the correct way... Have you ever been confused as to the sounds coming from your vehicle when you brake? From grinding and rattling to thumping and squealing, you can learn how to decode...
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.
For drivers who find difficulty in maintaining a steady speed and frequently experience big fluctuations, using cruise control can cut fuel use by over 40 per cent. While cruising, even a highly competent driver who isn’t using cruise control will tend to slow down and speed up in a repeated cycle, possibly several times per minute. Though fluctuations in speed may be slight, they do cause your engine to use more fuel than required.

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). 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.
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. Additionally, most cruise control systems allow you to adjust your speed using buttons. The system uses a forward-facing camera and sensors to detect the speed and distance of the vehicle in front of the driver.
