According to the research, cruise control reduces the mental workload of the driver. It reduces fatigue and increases the comfort of driving on a long-distance. The cruise control is also good to avoid speed violations. It resists the temptation to speed up the car.
Fortunately, on this page, you can learn everything you need to know about cruise control. In this powerful article, you are going to quickly learn what is cruise control in a vehicle, how does it work, and its types.
What Is Cruise Control In Vehicle
What is cruise control?
Cruise Control also known as speed control or auto cruise is a system that allows you to keep the car at a constant speed without holding the foot on the accelerator pedal. Technically, it is an electronic feature that reprograms the car’s setting to keep the car at a constant speed regardless of pressing and holding the foot on the accelerator pedal.
It is a kind of driving on auto-pilot mode. It automatically controls the car’s steady speed by taking the control of the throttle body. Cruise control comes in the 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 is fitted under the hood or in the cabin behind the dashboard.
In the early mechanical linkage throttle body, two cables are used for operating the cruise control, one cable goes to the accelerator pedal, and the second cable goes to the vacuum actuator to operate the throttle body for cruise control.
This vacuum actuator also pulls the cable connected to the accelerator pedal and actuates the throttle butterfly valve. The modern cruise control systems have a memory feature that means, it remembers the last time the cruise control system was canceled.
You can resume the previously canceled speed by tapping on the RES button. With the activated cruise control system, you can override the speed of the car by pressing the accelerator pedal. But once, you take the foot off from the accelerator pedal, the cruise control reduces the speed until it reaches the last SET speed.

Some cars do not engage the cruise system below a certain speed, typically less than 40 km/h or 25 mph.
How Does Cruise Control Work
Cruise control is an electronic system that keeps your car at a constant speed. It is activated by pressing the cruise control ON button while you are in driving. When the cruise control is activated, it manipulates the throttle valve electronically to maintain the desired speed.
The cruise control system has a group of buttons placed sometimes on the steering wheel or the windshield wiper or turn stalk or have separated stalk to SET the speed and increase or decrease the speed of the car.
The cruise control system can accelerate or decelerate the car 1 km/h or 1mph (depending upon the car manufacturers which unit they use) with the tap of a button. Tap the button ten times to go 10 km/h or mph faster.
Types Of Cruise Control
Below are the three types of cruise control.
- Regular Cruise Control
- Adaptive Cruise Control
- Predictive Or Semi-Autonomous Cruise Control
1. Regular Cruise Control
Regular or standard cruise control is a type of cruise control system that has all the features except increasing or decreasing the speed automatically. The regular cruise control sets, cancels, resumes, increases, and decreases the speed manually.
But it does not increase or decrease the speed of the car automatically if it comes across another car in front of you. The car does not sense another car ahead of you to slow or speed up, because there is no camera or radar fitted in front of the car.
2. Adaptive Cruise Control
Adaptive cruise control is an improved version of regular cruise control. It has many features; it holds a set speed as well as increases or decreases the car’s speed automatically. It slows down the car if it detects another vehicle in front of you and maintains the distance behind the car ahead of you. It even brings the car to a stop position by applying brakes.
The adaptive cruise control system uses a camera system or a nose-mounted radar system or laser at the front of the car, which detects the car ahead of you, typically up to 200 meters.
3. Predictive Or Semi-Autonomous Cruise Control
The predictive or semi-autonomous cruise control system has all the features as an adaptive cruise control system has. It has an additional feature of a GPS to assist the steering using lane guidance. The GPS directs the car about road conditions like slope, corner to slow or stop the car automatically.
