What Is The Cruise Control System And How Does It Work In Cars?
Table Of Content
Cruise control is widely available as standard equipment on most modern vehicles. 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. You just set the speed you want, and it'll keep your car cruising along at that speed, no problem. It's perfect for those long drives on open highways, but it doesn’t automatically react to other cars on the road. There are also various sensors on the steering wheel, brake and clutch (on in manual car) which will disengage the system incase the driver needs to take control of the vehicle again. However, it’s a tool designed to make the driver’s task easier and less stressful.
Understanding the Basics
To deactivate the system, the driver can either apply the brakes or turn off the cruise control switch.Standard cruise controle can be found on many vehicles, from entry-level models to high-end luxury cars. Cruise control, also known as speed control, is an electronic system that allows you to maintain a specific speed without manually controlling the accelerator pedal. The system uses sensors and electronic components to control the throttle and keep your car moving at a desired speed. First introduced in the late 1950s, cruise control has since become a standard feature in most modern vehicles you see on the road today. The driver can set the cruise control with the cruise switches, which usually consist of ON, OFF, RESUME, SET/ACCEL and COAST. These are commonly located on the steering wheel or on the windshield wiper or turn signal stalk.

Depending on the year, make and model, cruise control may be available for add-on or retrofit. Professional installation is recommended, and you’ll want to talk to a professional about the specific availability of parts and integration for your vehicle. Using cruise control also reduces wear and tear on both your engine and transmission by running things more smoothly and steadily, and reducing workload on both components. Drivers who have the most difficulty managing their cruising speed could be using 60 per cent more fuel than they need to. A governor was used by James Watt and Matthew Boulton in 1788 to control steam engines, but the use of governors dates at least back to the 17th century.

Each type of cruise control system has its own advantages and disadvantages, and drivers should choose the one that best suits their needs. Cruise control is convenient for long stretches of driving and it can keep you from speeding if you set your speed to the correct limit. However, if the road conditions are rainy or snowy, cruise control can be dangerous. To use cruise control safely, it’s best to know when you should and shouldn’t use it. [9] Using cruise control on the highway makes your driving more predictable to other drivers.

A graphic on the driver information screen displays a representation of the changing minimum distances as you use the button to scroll through them. This factor helps the cruise control respond quickly to changes, such as hills. If the car starts to slow down, the cruise control can see this acceleration (slowing down and speeding up are both acceleration) before the speed can actually change much, and respond by increasing the throttle position.

On the other hand, adaptive cruise-control is like having a smart companion. It uses sensors to detect the distance to the vehicle in front of us and automatically adjusts our speed to maintain a safe following distance. It’s a great feature for those highway drives with heavy traffic. Cruise control is a system that allows the driver to set their car to drive at a specific speed. The driver selects the speed, then takes their foot off the accelerator, and the vehicle will cruise at the set speed.
In this post, we'll explore how cruise control works, its benefits, and how to use it safely to make your driving experience more comfortable. On the latest vehicles fitted with electronic throttle control, cruise control can be integrated into the vehicle's engine management system. Modern "adaptive" systems include the ability to automatically reduce speed when the distance to a car in front, or the speed limit, decreases. In a proportional control system, the cruise control adjusts the throttle proportional to the error, the error being the difference between the desired speed and the actual speed. So, if the cruise control is set at 60 mph and the car is going 50 mph, the throttle position will be open quite far.
No matter how fancy your cruise control is, these systems can be greatly influenced by external conditions like weather and traffic, and they should always be used as aids, not replacements, for attentive driving. The purpose of a cruise control system is to accurately maintain a speed set by the driver without any outside intervention by controlling the throttle-accelerator pedal linkage. Speed control existed in early automobiles such as the Wilson-Pilcher in the early 1900s. 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. Originally, cruise control was offered as a luxury feature, but as inventors and engineers improved the system, cruise control eventually became as widespread as it is today.
Does cruise control save fuel?
Cruise control is far more common on American cars than European cars, because the roads in America are generally bigger and straighter, and destinations are farther apart. Speed limiters can be installed in vehicles as a safety feature, particularly in commercial vehicles like trucks and buses. These vehicles are often required by law to have speed limiters installed, as they can help prevent accidents caused by excessive speed. In addition, speed limiters can help improve fuel efficiency and reduce wear and tear on the vehicle’s engine and brakes. 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.

Conversely, if you go up a hill, the reverse occurs – the level of acceleration that is detected by the PID system sinks, and the system responds by opening up the throttle.

On lengthy journeys, cruise control can help reduce driver fatigue. Moreover, it can aid in preventing speeding and improving fuel efficiency by minimizing unnecessary acceleration and braking. 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.
For example, it won’t accelerate as hard in certain situations and it’ll accelerate harder when necessary.

For example, the Set and Accelerate functions are often incorporated into the same button or toggle. Although individual carmakers may provide differing controls, the fundamentals of a basic cruise control system remain the same. That is, the driver manually sets and then can adjust the desired speed, while the cruise control system automatically responds to the driver’s input via steering-wheel-mounted controls. In some modern cars, the cruise control system is enhanced with additional sensors and algorithms that enable it to adapt to the surrounding traffic and road conditions. These advanced systems are known as adaptive cruise control, intelligent cruise control, or active cruise control. For most drivers, using cruise control on the highway at 80 km/h can reduce fuel consumption by about 20 per cent.
If the cruise control in your vehicle suddenly kicks off, a few things may be to blame. This was my 4th long drive on my Hycross and I learnt a lot of things about this hybrid vehicle in this specific trip. Yesterday, I got an overall average of 18.9 km/l on my drive from Delhi to Punjab. I noticed the same average of 18.9 km/l by using the tank-to-tank method and I had filled normal petrol from Indian Oil in this car.
At its core, cruise control involves a series of sensors that monitor the vehicle's speed and a control unit that regulates the throttle. When the driver sets the cruise control to a specific speed, the system adjusts the throttle to maintain that speed. If the car begins to slow down because of an incline (e.g. going up a hill), the system will open the throttle to accelerate. Conversely, if the car starts to speed up due to a declin (e.g. going downhill), the system will close the throttle to decelerate. The cruise control takes its speed signal from a rotating driveshaft, speedometer cable, wheel speed sensor from the engine's RPM, or internal speed pulses produced electronically by the vehicle.
