On the latest vehicles fitted with electronic throttle control, cruise control can be integrated into the vehicle's engine management system. Modern "adaptive" systems include the ability to automatically reduce speed when the distance to a car in front, or the speed limit, decreases. 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. Modern cruise control is electronic and uses a computer to control your car’s speed.

It can not only potentially help you get better gas mileage but also make driving much more comfortable. 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. Another inventor named Harold Exline, working independently of Riley, also invented a type of cruise control that he first installed on his car and friends' cars. 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).

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.
Adaptive cruise control
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. If conditions are right to use cruise control in your car, turn on the system. If it’s your first time using your car’s cruise control system — or if you’re not 100% sure how to turn on cruise control in your car —the process starts before you crank the engine.

The system is a servomechanism that takes over the car's throttle to maintain a steady speed set by the driver. Cruise control is a feature on some vehicles that allows the driver to take their foot off the accelerator while the onboard computer maintains the vehicle’s speed. Within cruise control, you can typically also adjust your speed up and down using buttons. Speed control existed in early automobiles such as the Wilson-Pilcher in the early 1900s. One potential downside to using cruise control is that it can result in the driver having a reduced reaction time when they must respond quickly to an unexpected situation on the road.

All cruise control systems must have the capability to be turned off explicitly and automatically when the driver depresses the brake pedal and often also the clutch. Cruise control systems frequently include a memory feature to resume the set speed after braking and a coast feature to reduce the set speed without braking. When the cruise control is engaged, the throttle can still accelerate the car, but once the pedal is released, it will slow down the vehicle until it reaches the previously set speed. Automatic braking systems use either a single or a combination of sensors (radar, lidar, and camera) to allow the vehicle to keep pace with the car it is following, slow when closing in on the vehicle in front, and accelerate to the preset speed when traffic allows. Some systems also feature forward collision warning systems, which warn the driver if a vehicle in front—given the speed of both vehicles—gets too close within the preset headway or braking distance.
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. Speed 2 falls far short of its predecessor, thanks to laughable dialogue, thin characterization, unsurprisingly familiar plot devices, and action sequences that fail to generate any excitement. However, there is one movie from her illustrious career that Bullock regrets starring in. The 59-year-old has featured in a wide range of super successful films, including the likes of The Blind Side and The Lost City.

The cruise control systems of some vehicles incorporate a "speed limiter" function, which will not allow the vehicle to accelerate beyond a preset maximum; this can usually be overridden by fully depressing the accelerator pedal. 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. The throttle position was automatically adjusted by a vacuum control that opened and closed the throttle based on input from the speedometer cable rather than through an adjustable control on the dashboard.[10][11] The unit would shut off anytime the brakes were applied.
Motorbiscuit reminds drivers that cruise control is not a hands-free driving feature. Distracted driving is a bad driving habit that can lead to crashes, so always stay alert. Adaptive cruise control (ACC) is the latest type of cruise control that’s becoming widely available in cars. ACC maintains your speed but incorporates sensors to measure the distance to the car ahead. Once you set a distance, the ACC adjusts your speed to ensure you stay at that distance — usually a car length or two. For example, some cars have a combined button to set the initial speed and accelerate.
According to Scientific American, cruise control in cars has been around since the early 1900s, but it’s changed over time. Early versions were mechanical, using a second throttle lever mounted to the steering wheel. The cruise control takes its speed signal from a rotating driveshaft, speedometer cable, wheel speed sensor from the engine's RPM, or internal speed pulses produced electronically by the vehicle. Most systems do not allow the use of the cruise control below a certain speed - typically around 25 or 30 mph (40 or 48 km/h). The vehicle will maintain the desired speed by pulling the throttle cable with a solenoid, a vacuum-driven servomechanism, or by using the electronic systems built into the vehicle (fully electronic) if it uses a 'drive-by-wire' system. Wait for a moment when it’s appropriate to use cruise control before turning it on.
Others have fine-tuning buttons that you can click to increase or decrease your speed by a set amount, often one mph. The driver must manually bring the vehicle up to speed and use a button to set the cruise control to the current speed. Modern cruise control (also known as a speedostat or tempomat) was invented in 1948 by the blind inventor and mechanical engineer Ralph Teetor.[4][5] He came up with the idea due to being frustrated by his driver's habit of speeding up and slowing down as he talked. Cruise control is one feature you’ll want from a good car for road trips and other frequent highway driving.
Accelerating with the cruise control system in a car is like using the pedal in terms of acceleration rates and should feel familiar. Slowing down is akin to taking your foot off the gas and won’t slow the car as fast as applying the brake. When decelerating using the cruise control, give yourself adequate time to change speeds or use the brakes to slow down and hit the “set speed” button again. To use cruise control, you can typically press buttons on your steering wheel to activate the system, set your speed, adjust your speed up or down within the system, and deactivate the system. Using cruise control lets you set a speed for your car to maintain even if you take your foot off the gas. Cruise control can also prevent speeding and increase fuel efficiency by limiting unnecessary acceleration and braking.
