Quick acceleration and deceleration change the vehicle’s momentum drastically and wastes fuel. So, using cruise control is most fuel-efficient on level highways and long uphill and downhill grades. However, you need to manually control the gear shifts when the vehicle slows down or accelerates when the system is engaged. Typically, the cruise control button is located on the steering wheel for easy access. However, the location of the button may vary depending on the make and model. However, almost all vehicles costing above Rs. 5 lakhs are equipped with cruise control.

By means of ultrasonic sensors, radar, and a windshield camera, the vehicle will maintain a consistent distance from the one ahead in traffic while staying oriented on the road. The driver takes full manual controlwhen the congestion clears or Traffic Jam Assist otherwise becomes unsuitable for the situation. Cruise control is a feature allowing the driver to set a predetermined speed, which the system’s computer maintains until the driver adjusts the speed, taps the brake, or disengages the system.
Adjust speed as necessary
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. The cruise control system controls the speed of your car the same way you do -- by adjusting the throttle position. But cruise control actuates the throttle valve by a cable connected to an actuator, instead of by pressing a pedal. The throttle valve controls the power and speed of the engine by limiting how much air the engine takes in (see How Fuel Injection Systems Work for more details). Another major benefit of using cruise control is that you will experience greater fuel efficiency.
Cruise control vs adaptive cruise control: Key differences
Braking capacity while the system is active differs, but typically, the driver will be alerted to brake heavily if necessary (if a driver ahead does the same for instance). However, it’s a tool designed to make the driver’s task easier and less stressful. On the other hand, neither conventional nor adaptive cruise control relieves the driver of the ultimate responsibility of safely driving the car. When used appropriately, conventional and adaptive cruise control are safe.

Rather more complex than that, though, is the question of exactly how it keeps the vehicle moving at a specific speed. If you've ever wondered how cruise control works, what the pros and cons of using it are, how it's developed since its introduction, and/or when to use it, this is just the piece for you. After turning on cruise control, you’ll need to set your desired speed. Many systems set the cruise control at the current speed, while others require you to manually set one. You can increase and decrease this speed as needed without interrupting the mechanism.

If the vehicle ahead slows down or speeds up, ICC automatically adjusts the speed of the driver’s car to maintain a safe following distance. Unlike regular speed control, ICC can also bring the car to a complete stop and resume driving when the vehicle ahead starts moving again. Cruise-control is most effective during extended journeys on expansive, straight highways, such as interstate highways, where vehicles are maintaining a relatively steady pace. It is not suitable for use in stop-and-go traffic, inclement weather conditions like snow, ice, or heavy rain, or on narrow, winding roads with frequent changes in speed limits. Disengaging cruise control in these scenarios could require significant time and attention, potentially leading to accidents. Cruise control is an electronic device within your vehicle that controls the speed of your vehicle.
Types of Cruise Control Systems
While it can help reduce driver fatigue and improve fuel economy on long drives, it requires the driver to remain attentive and adjust the speed manually if necessary. Therefore, it is important for drivers to use it responsibly and not rely solely on the system to maintain a safe driving experience. 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.

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... As mentioned earlier, cruise control also has some cons, which are listed below.
What is adaptive cruise control?
It uses GPS and map data to see into the future and predict what's coming up on the road, like hills or curves, and adjusts your speed accordingly. This means you get a smoother ride and better fuel efficiency, but it all depends on the quality of the GPS and map data. If that's a bit out of date, your fortune-telling cruise control might not be so accurate.
Stop-and-Go Cruise Control is an advanced form of speed control, Unlike other types of cruise controle systems. It can maintain a safe distance from the vehicle ahead, even in stop-and-go traffic. This type of cruise controle is designed to help drivers reduce stress and fatigue when driving in heavy traffic conditions. The system uses sensors and cameras to detect the distance and speed of the vehicle ahead.
Cruise control offers several benefits to drivers, especially during long road trips or highway driving. Adaptive cruise control, which monitors the ever-changing road ahead continuously via radar or laser, is potentially better equipped to handle congested roads. There's no definitive answer on whether that's the case, however, because this feature is very different from vehicle to vehicle. Cruise control systems, even adaptable cruise control, may not always detect these streets correctly, causing accidents. Heavy, or stop-and-go traffic is not ideal for safely using cruise control.
They help reduce driver fatigue by maintaining a steady speed and allow for safer changes in seating position. Some drivers use cruise-control to avoid unintentionally exceeding speed limits, thus promoting safer driving habits and potentially reducing the risk of speeding tickets. Additionally, these systems can enhance fuel efficiency by maintaining a constant speed, which can lead to cost savings over time.
However, unlike conventional cruise control, this new system can automatically adjust speed in order to maintain a proper distance between vehicles in the same lane. This is achieved through a radar headway sensor, digital signal processor and longitudinal controller. If the lead vehicle slows down, or if another object is detected, the system sends a signal to the engine or braking system to decelerate. Then, when the road is clear, the system will re-accelerate the vehicle back to the set speed. 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.
Ultimately, it’s not hard to save fuel if you let your vehicle automatically maintain a constant cruising speed. It’s an electrical system that allows you to set your car to a specific speed and take your foot off the accelerator. Cruise control is a system that automatically controls the speed of a motor vehicle. The system is a servomechanism that takes over the throttle of the car to maintain a steady speed as set by the driver.
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. While knowing how to use cruise control can reduce leg fatigue, it can require more mental concentration. The car will maintain speed even if road conditions change, so you must carefully pay attention to the road and traffic. When you’re using your car’s cruise control feature, don’t forget your defensive driving skills.
Instead, a computer linked to various sensors and throttle controllers controls the function via a wireless system. This newer technology can automatically adjust speed to match the speed of the vehicle in front while maintaining a safe distance. 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. Predictive Cruise Control is like the fortune teller of cruise control systems.
