In fact, utilizing the system can be quite dangerous if you’re not careful. 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. However, you need to manually control the gear shifts when the vehicle slows down or accelerates when the system is engaged. Adaptive cruise control is the more advanced version of the standard automatic cruising system.
How Cruise Control Systems Work
It is a system that accurately maintains the speed set by the driver without any external intervention. It automatically controls the speed of a car and only allows the vehicle to hit a speed set by the driver. You can even find this feature in the top-spec variants of some of the affordable hatchbacks and sedans.
Wheel Alignment vs. Balance: What’s the Difference?
As you can see, cruise control is a great way to relieve much of the stress that comes with everyday driving. The constant rate of speed can also drastically improve fuel efficiency for longer drivers. Cruise control has had a positive impact on the driving industry for 70 years and shows no signs of disappearing anytime soon. 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.

This typically includes ACC and another technology like lane-centering assist or lane-keeping assist. With these technologies, the vehicle can steer, accelerate, and brake on its own in certain conditions. Level 2 still requires the driver’s hands on the wheel and eyes on the road. Once the cruise control is active, you’ll need to use your gas or brake pedal to bring the car to the speed you want and then use the “set speed” button to lock in your speed. Make sure your speed is within your area’s established speed limits.
How to set cruise control
It adjusted the vehicle's speed by engaging the throttle with the help of an actuator that is controlled by a cable. The throttle valve is responsible for the power and speed generated by the engine. So, depending on the speed set by the driver, the system automatically adjusted the throttle position. Cruise control (also known as speed control, cruise command, autocruise, or tempomat) is a system that automatically controls the speed of an automobile.
What Is Cruise Control In Vehicle
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. 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 your 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. Drivers must still be vigilant in paying attention to the road and their surroundings, and be prepared to take over control of the vehicle if necessary.
Speed Limits
Heavy, or stop-and-go traffic is not ideal for safely using cruise control. When engaging cruise control on the highway, ensure your lane is clear and there are no vehicles stopping ahead. This factor helps the cruise control respond quickly to changes, such as hills. However, almost all vehicles costing above Rs. 5 lakhs are equipped with cruise control. Gone are the days when this feature was limited to premium vehicles.
The benefits of using the cruise control feature are better fuel efficiency and reduced foot fatigue during long drives. 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.
What Is the Difference Between Adaptive Cruise Control and Self-Driving?
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. This modern feature uses sensors and radar to maintain a safe distance from the vehicle ahead, adjusting speed automatically.
Once you’ve reached your desired speed, engage the cruise control. This step will vary widely based on your vehicle make and model, however, many cruise control settings are accessible from the steering wheel controls. Controlling the speed of a car is a classic application of control system theory. The cruise control system controls the speed of the car by adjusting the throttle position, so it needs sensors to tell it the speed and throttle position. It also needs to monitor the controls so it can tell what the desired speed is and when to disengage. Before engaging the cruise control in a car, remember that the system is not intended to be used in adverse weather conditions.
The most important input is the speed signal; the cruise control system does a lot with this signal. First, let's start with one of the most basic control systems you could have -- a proportional control. The brain of a cruise control system is a small computer that is normally found under the hood or behind the dashboard.

It is also good to avoid speed violations and resists the temptation to speed up the car. As stated earlier, some systems will bring your vehicle to a complete stop to match traffic flow. Even more intelligent systems can then accelerate as the traffic flow resumes. By the early 1990s, Japanese carmakers were adding a form of forward collision warning to their cruise control, but it was still up to the driver to react and apply the brakes. Not until Mercedes-Benz developed its Distronic cruise control did cruise control with self-braking make its first public appearance. When carmakers pitched cruise control to the American public more than half a century ago, they framed it as a way to maintain a safe, consistent speed on the highway and a path to conserving fuel.
When cruise control is no longer needed, or you need to quickly make a maneuver, simply apply pressure to the brakes to disengage the system. Once deactivated, you will be in full control of your vehicle once again. 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). Step 4 - Keep your eyes on the road as it is very easy to get distracted when the car is accelerating automatically.
Ford’s Co-Pilot360 includes adaptive cruise control with stop-and-go and lane-centering. It’s less about hands-free driving and more about reducing driver fatigue and enhancing safety. This system is excellent for everyday driving, offering features like speed sign recognition and evasive steering assist. Tesla’s FSD Beta represents a leap forward in autonomous driving technology. It’s not just a cruise control system but an advanced driver-assistance system capable of navigating complex driving scenarios. Key features include automatic lane changes, stop sign and traffic light recognition, and the ability to navigate city streets.
It can not only potentially help you get better gas mileage but also make driving much more comfortable. Cruise control offers several benefits to drivers, especially during long road trips or highway driving. Cruise control technology not only adds convenience to driving but also significantly impacts safety and efficiency. This section delves into the real-world implications of using cruise control, supported by safety statistics and research findings. Discover expert insights and practical tips on using cruise control effectively. This comprehensive guide covers everything from basic operations to advanced features, safety tips, and troubleshooting.
