Cruise control is a feature that comes in handy when you drive at a constant speed. It is an electric system that allows you to set your car to a specific speed, letting you take your foot off the accelerator pedal. Another great benefit to using cruise control is that you are going to have greater fuel efficiency. Your vehicle will consume much less fuel if you cruise at a steady speed rather than accelerating at each section of the open road. When you accelerate sharply, it makes your engine use more energy, and you could be using 60% more fuel than one who uses cruise control. Ultimately, it's not hard to save on fuel if you let your vehicle automatically maintain a steady cruising speed.
Why Use the Cruise Control System?
There are several variations of semi-autonomous cruise control that include additional convenience features for the driver. 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.
What Is Cruise Control In A Car and How It Works
Here, the cruise control system maintains throttle pressure, even in situations where it should be released instead. Older cable-based cruise control systems seem more prone to this rare problem, in which the cable can slip or bind, making the throttle stick into position. More modern vehicles with electronic throttle and monitoring systems make this problem even less likely.

If you wish to use cruise control within city limits, adaptive cruise control will be a better choice. You must note that you do not use the cruise control system in adverse weather conditions like heavy rains, thunderstorms, and snow. During these conditions, the visibility on the road is very low, making it unsafe for the car to cruise at high speed.

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. The throttle valve controls the power and speed of the engine by limiting how much air it takes in (since it’s an internal combustion engine).
Do not attempt to set cruise control when you are traveling over the speed limit. Luxury automakers such as Tesla and Audi are implementing the newest rendition of cruise control on their latest vehicle models – Semi-autonomous Cruise Control. It works largely the same as adaptive cruise control, but assists drivers with lane guidance and steering.
What Does Cruise Main Mean in a Car? Everything You Need To Know!
The system constantly maintains the speed set by you (driver) irrespective of road conditions. For example, if there’s an incline ahead, cruise control adjusts the throttle accordingly to maintain the same speed. Cruise control in a car replicates the inputs of a driver to control the vehicle’s speed.
Advantages & Disadvantages Of Adaptive Cruise Control
However, an additional limiter can be added as an option in many European-made cars, as well as Tesla, Ford, and Nissan. Drivers are still required to keep their foot on the pedal to keep their vehicle in motion, but will not be able to accelerate past a predefined speed limit. Controlling the speed of a car is a classic application of control system theory.
This factor helps the cruise control respond quickly to changes, such as hills. Cruise control offers several benefits to drivers, especially during long road trips or highway driving. One of the main reasons you should consider using the cruise control system is its fuel efficiency. As mentioned earlier, the main button to turn on this system is Cruise Main, but this is not the only control you need to switch on for moving your car to the cruise control system. Here we have listed all the controls and buttons you need to know of to use the cruise control system effectively.
The main system, however, cannot function completely just by pressing the cruise main button. You have to set the other settings of the system, decide on the speed, and perform multiple other operations before you can finally use this system. You might want to turn off your adaptive cruise control for a few reasons. Maybe you’re approaching a stop sign or traffic light and must slow down. Or perhaps you’re going downhill and don’t want the car to speed up too much. You won’t have to worry about constantly adjusting your speed or worrying about traffic.
The cruise control symbol is one such symbol that may be confusing or unfamiliar to some drivers. In this blog post, we will discuss what the cruise control symbol means and how to use it. Cruise control is safe when operated in safe driving conditions, by drivers with valid licenses who are sober and able to drive and use cruise control.
It connects to the throttle control seen in the previous section, as well as several sensors. The diagram below shows the inputs and outputs of a typical cruise control system. 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. On an engine, the governor uses centrifugal force to adjust the throttle position to adapt the engine's speed to different loads (e.g., when going up a hill).
It automatically controls the car’s steady speed by taking the control of the throttle body. It comes in cars having a drive-by-wire system where an electronically controlled throttle body is manipulated by a cruise control computer. The cruise control computer is a small computer that you can fit under the hood or in the cabin behind the dashboard. 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. Tapping the knob in the opposite direction will decelerate the vehicle.
