There are several variations of semi-autonomous cruise control that include additional convenience features for the driver. PREDICTIVE SPEED ASSIST ALERTSIf the speed sign recognition system detects a speed limit below the minimum adaptive cruise control set speed, a tone sounds and the system returns to standby mode. Once familiar with your car’s cruise control system, you can try it out. Wait for a moment when it’s appropriate to use cruise control before turning it on. Check that the road is clear, that weather conditions are good, and that you’re on a highway or a road where you won’t have to stop or change speed often.
Wet or Icy Conditions
Then, when the road is clear, the system will re-accelerate the vehicle back to the set speed. 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. 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.

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. Cruise control has come a long way since first invented and patented by Ralph Teetor in 1950, who originally named it the “Speedostat”. Chrysler Corporation was the first manufacturer to offer the groundbreaking mechanism as an option on several of its luxury vehicle models nine years later.
Adaptive Cruise Control (ACC)
It’s more advanced than traditional systems but still requires driver attention. 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. Cruise control is a handy feature for drivers that allows you to maintain a constant speed without having to keep your foot on the gas pedal. 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.
This innovative feature was designed to help drivers maintain a steady speed, reduce fatigue while driving, and improve fuel efficiency. Over the years, cruise control technology has undergone significant advancements, leading to the development of sophisticated systems like adaptive cruise control. Adaptive cruise control uses sensors around the vehicle’s exterior to maintain speed while keeping a safe following distance from the car ahead. The system will slow you down and speed you up as the flow of traffic fluctuates throughout your commute, removing a lot of the stress from daily driving.

General Motors’ Super Cruise system is available in select Cadillac models and provides hands-free driving assistance on compatible highways. It uses LiDAR map data, high-precision GPS, and a driver attention system to ensure safety. Unlike Tesla’s FSD, it’s limited to highway use but excels in hands-free driving comfort and safety.

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.
As you’re learning how to operate a vehicle, understanding cruise control will help increase your comfort behind the wheel and knowledge of driving. Some ACCs can only slow down slowly by using less throttle, while others can take control of the brakes and actively brake. If it has autonomous emergency braking, you car will stop if the vehicle in front of it suddenly stops. In icy conditions and when driving in fog, you need more control over your speed. It can also be dangerous in heavy rain when there’s a risk of aquaplaning. In the past, you’d only find it in luxury cars but it’s now a common feature in most new cars on the market.
Many cars use actuators powered by engine vacuum to open and close the throttle. These systems use a small, electronically-controlled valve to regulate the vacuum in a diaphragm. This works in a similar way to the brake booster, which provides power to your brake system. Driving while fatigued is never a good idea, but even less so while using cruise control. Utilizing the system may add to your fatigue, as you give your vehicle more control of the journey. If you’re even the least bit tired, you should never turn on cruise control.
Many of us would admit that we’re not very consistent in maintaining a steady speed on the road, even on motorways. Cruise control is designed to be used on A-roads and motorways that don’t have frequent stops and turns to negotiate. Founded in 1937, Progressive is the third largest personal car insurer in the U.S. with over 26 million drivers enrolled. Life Lanes helps you do just that, from owning a car and home to other life moments and adventures.
CANCELING THE SET SPEEDPress the button, or tap the brake pedal to cancel the set speed. If the car in front suddenly speeds off, however, your car won’t routinely follow it. Instead, the ACC system will hold the pre-set speed until you change it, or it catches up with another vehicle.
Occasionally, you may encounter issues with your cruise control systems. Common problems include cruise control not engaging or disengaging unexpectedly. Possible causes may include a faulty brake light switch, malfunctioning sensors, or issues with the control module.
