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. For example, Audi's Traffic Jam Assist technology can be activated in tandem with its adaptive cruise control, thereby supporting the driver in conditions that aren't optimal for the latter. 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.
Instrument Checks and First Drive
Initially, the system used a cable to control the accelerator (throttle valve). 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. 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.

Electra, the navigation and telecommunications relay payload, can provide UHF coverage to Mars landers and rovers on the surface using its nadir-pointed (pointed straight down at the surface) antenna. Chefs work all day in the galley to prepare thousands of meals for the guests on board each of Royal Caribbean’s ships. When you pull into ports like Perfect Day at CocoCay, pay attention to the announcements to learn if you’ll be disembarking on the port or starboard side of the ship.

Because you don’t have to keep your foot on the accelerator, it’s easier to nod off – and lose control of your vehicle. On slippery roads – that includes snow, ice, heavy rain and hailstorms – as this increases the chances of sliding. 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).

The car also sports another set of eyes in the form of a standard camera that points through the windscreen. This also looks out for nearby hazards, such as pedestrians, cyclists and other motorists, whilst also reading road signs and detecting traffic lights. The bumper-mounted radar, which is already used in autonomous cruise control, looks out for vehicles in front of and behind the car. If you’re driving too close to the car in front, it will warn you in two stages. First, it will alert you with visual and acoustic signals, and then with a short braking jolt. Some units employ a laser, while others use an optical system based on stereoscopic cameras.
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). Cruise control is far more common on American cars than European cars, because the roads in America are generally bigger and straighter, and destinations are farther apart.
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. If you experience any problems with your cruise control, it's best to have a qualified technician diagnose and repair the issue for you.
How to Use Cruise Control on a Car
However, the location of the button may vary depending on the make and model. Step 4 - Keep your eyes on the road as it is very easy to get distracted when the car is accelerating automatically. 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. The 77-GHz Autocruise radar system made by TRW has a forward-looking range of up to 492 feet (150 meters), and operates at vehicle speeds ranging from 18.6 miles per hour (30 kph) to 111 mph (180 kph). 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).
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. There are several variations of semi-autonomous cruise control that include additional convenience features for the driver. Cruise control can be installed on manual transmission cars, but it requires a more advanced system than the one used for automatic transmissions. Manual transmission cruise control systems are typically more expensive and less common.
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.
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. Adaptive cruise control is a more advanced technology that enables you to set a specific speed while the system automatically reads the traffic ahead and keeps your car at a safe following distance. 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.
This action captures the current speed of the vehicle and sets it as the target speed for the cruise control system to maintain. 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. Now, if conventional cruise control is your old reliable friend, then Adaptive Cruise Control (ACC) is like that friend's tech-savvy younger cousin. ACC isn't just maintaining your set speed, it's also keeping an eye on the car in front of you. If that car slows down, ACC slows your car down to keep a safe distance.
For example, you may refrain from driving the car at cruising speeds when it’s raining heavily. The low visibility and unpredictable road conditions make it unsafe to drive at such speeds. So, always be mindful of the weather condition and your surroundings before engaging the system. As you can see, cruise control is a great way to relieve much of the stress that comes with everyday driving.
As mentioned earlier, cruise control also has some cons, which are listed below. While wheel alignment and balance both contribute to a smoother ride, the services are quite different. 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...
Experienced drivers, of course, will probably be familiar with the basics of what cruise control does, even if they haven't really used it themselves. 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. Gone are the days when this feature was limited to premium vehicles. Even vehicles with affordable price tags are equipped with intelligent features. Sometimes you may get confused between cruise control and speed limiter as both are related to the car's speed.
It allows the driver to maintain a constant speed of 25 mph without holding their foot on the accelerator. Although the feature has been around for 70 years, automotive manufacturers continue to improve upon the technology to provide drivers with increased comfort, luxury, and convenience whenever they’re behind the wheel. Most systems will prevent the vehicle from increasing engine speed to accelerate beyond the chosen speed. However, they will not apply the brakes in the event of overspeeding downhill, nor stop the car from going faster than the selected speed even with the engine just idling.
