Whats The Difference Between Normal And Adaptive Cruise Control

Adaptive Cruise Control | New Car Technology | Autotrader

Modern cruise control was invented in 1948 by the American engineer Ralph Teetor. Fun fact, the first car to offer cruise control was the 1958 Chrysler Imperial, and the automaker marketed the feature as auto-pilot.

Basic cruise control automatically presses the acceleration pedal or holds it at a certain spot, enabling drivers to take their foot off the pedal in specific situations. Over the years, auto manufacturers improved the feature set by leaps and bounds.

For example, my old 2011 Toyota Tacoma has cruise control, but its nothing fancy. I can turn it on, set a speed, then manually click the control stem up/down to increase or decrease my speed if neededbut it barely works. Once I tap the brake, its all over, and everything shuts off. However, there is a resume button I can easily tap to let the system instantly go back to my previously set speed. Thats about the extent of its control.

And while thats moderately helpful, driving with ACC is a vastly better experience. Adaptive cruise control isnt anything new, either. Unfortunately, the feature was reserved for more expensive luxury vehicles back in 2011.

Challenge #: Curving Roads

Your ACC system looks directly in front of you for other vehicles. Because it only looks forward, your ACC system may have trouble detecting traffic on curving roads.

In the image to the right, see how ACCs field of view works when the road curves. Its view may include traffic in another lane. It may also miss vehicles in your own lane. In situations like this, your ACC system may not react appropriately to the traffic around you. In the example, your ACC system may unexpectedly slow down if it detects the semi in the other lane.

What Would You Do?

Look at scenario in the image below. Imagine yourself driving the blue vehicle. Think about the questions shown below.

  • As you approach the curve, how might your ACC system respond?
  • How should you respond?
  • How might your ACC system respond? When Car A goes around the curve, my ACC system may not detect it and the system may unexpectedly accelerate.
  • How should you respond? If my system accelerates, I should maintain a safe speed manually until the road is straighter.
  • Which Ford Models Have Adaptive Cruise Control

    Most cars have utilized the cruise control feature for many years it allows drivers to set their vehicle to a certain speed, and it will maintain that speed as long as the feature is activated. However, in more recent years, cruise control received an upgrade.

    With Fords Adaptive Cruise Control feature, not only can drivers select the cruising speed of the vehicle, they also have the ability to set the distance between their vehicle and the one in front of them. When the car in front of you slows down, yours will too and it automatically picks its speed back up when traffic does. Adaptive cruise control consistently upgrades to become even more intuitive for drivers.

    But which Ford models are equipped with this incredible safety technology?

    Challenge #: Merging Traffic

    ACC systems detect other vehicles directly in front of you. Because of the systems field of view, ACC may not detect a vehicle that is in your lane but not directly ahead of your car. This can include vehicles that are merging into or out of your lane. In the example, Car A may be outside of your ACCs field of view and yet still in front of you.

    What Would You Do?

    Look at the scenario in the image below. Imagine yourself driving the blue vehicle. Think about the questions shown below.

  • How might your ACC system respond?
  • How should you respond?
  • How might your ACC system respond? If Car B moves into its field of view too quickly, my ACC system may brake unexpectedly or shut off.
  • How should you respond? I should monitor the system and traffic, and take control manually if necessary.
  • The Smart Buy Average Market Price

    What is adaptive cruise control, and how does it work?

    The Smart Buy Average Market Price is a proprietary mathematical calculation based on actual recent transactions either in your local area or nationally. It provides a statistically accurate understanding of what other buyers are paying for the vehicle you have selected and as you have configured it. Adjustments to the calculation beyond make, model, and trim are normalized based on detailed, anonymized transaction information. This accounts for the fact that most or all recently-sold vehicles included different option combinations than your specified vehicle configuration. The data underlying the Smart Buy Average Market Price calculation are filtered for extreme outliers and subjected to a weighted averaging process that considers factors such as the recency of transactions and the timing of data lags. In certain instances, the calculated result is adjusted to take account of abrupt changes in the market that may not yet be fully reflected by recent transaction prices. In all cases where the Smart Buy Average Market Price is shown there is sufficient sample size and transaction detail to be statistically reliable.

    Adaptive Cruise Control: What Is It And How Does It Work

    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. Although the fuel savings were minimal, both claims were accurate.

    Simple to use, all you need to do is turn on the system in your vehicle, reach your desired cruising speed, and set it. The system then assumes control of the accelerator, maintaining the set speed until the driver engages the brake. Easy peasy.

    Automotive engineers tweaked around the edges of cruise control for the next 35 years. However, cruise control didnt evolve much beyond the first system that found its way into the 1958 Chrysler Imperial.

    In essence, not only did the 1999 S-Class introduce the driver-aid technology adaptive cruise control , but it also set the cornerstone of the foundation for self-driving vehicles.

    Cruise control is still the more prolific of speed controls offered on todays new cars, but adaptive cruise control has started gaining ground. More car models provide it as standard or as an available option. But, what exactly is adaptive cruise control, and how does it work? Lets see.

    What Is The History Of Adaptive Cruise Control

    The first semblance of ACC was debuted by Mitsubishi on its Diamante sedan in 1995. Dubbed Preview Distance Control, the system utilized a Lidar and a camera to detect if the distance to the vehicle ahead was closing and would ease off the accelerator or downshift the transmission to reduce the cars speed.

    Its limitation, however, was the absence of control over the brakes. Therefore, if the distance to the car in front was reducing rapidly as in emergency braking or coming to a complete halt, the system could only produce a warning for the driver to intervene and apply the brakes manually.

    Nonetheless, the motoring worlds wait for a proper ACC system came to an end in 1999 as Mercedes-Benz introduced Distronic in the W220 S-Class. This would represent the first, true ACC as all Mercedes-Benz cars of the time incorporated stability control, meaning that provisions for autonomous braking were readily available and could be integrated with the ACC for full functionality.

    Adaptive Cruise Control Can Follow A Vehicle To A Stop

    On most vehicles, Adaptive Cruise Control can follow a vehicle ahead to a stop. When the vehicle ahead starts moving again, you should check that its safe to proceed and then either press the accelerator pedal or RESUME button to continue driving. For very brief stops, Adaptive Cruise Control will automatically resume and follow the vehicle ahead.

    Adaptive Cruise Control has limited braking capability, so if the vehicle youre following stops too suddenly, youll get an alert to take action by quickly applying the brakes yourself.

    If your vehicle has the Driver Attention System on the steering column, Adaptive Cruise Control may automatically resume and follow the vehicle ahead for longer stops, if the system detects that youre paying attention to the road.

    How to Use Adaptive Cruise Control (ACC) with Low-Speed Follow

    One of the main advantages of adaptive cruise control like the one found in the BMW 3 Series is how easy it is to use. With buttons located on the steering wheel, drivers have control right at their fingertips. These buttons allow the driver to adjust the ACC and set the speed at which they want to travel.

    Once set, the ACC will keep your car in motion while maintaining a safe distance from the traffic around you. While using your ACC, your car will optimize its fuel efficiency by traveling at a constant speed.

    It’s also super easy to turn the cruise control off and get back in charge of your vehicle. The moment a driver touches the brakes or accelerator, the ACC automatically turns off, and you regain control. It’s that simple.

    Many ACC systems have their flaws, however, and some can encounter quite a few issues. Some sensors might not work as they are meant to in tricky weather conditions, which is a reason to maintain full control in such circumstances.

    Apart from the weather, another drawback of ACC is the loss of concentration a driver may experience. Cars with adaptive cruise control are basically driving themselves, which means the driver can become complacent when observing the road.

    Gone are those punishing commutes where your foot hurts from stopping and starting in traffic. ACC takes care of that all you need to do is stay alert and look out for potential hazards.

    How Does It Work

    Parts related to a typical ACC system

    Like standard cruise control systems, ACC keeps your car at the speed you set, as long as there is nothing in front of you. A sensor unit is added to determine the distance between your car and other cars in front you.

    Speed and distance sensors. ACC uses information from two sensors: a distance sensor that monitors the gap to the car ahead and a speed sensor that automatically accelerates and decelerates your car. ACC uses information from these sensors to adjust your speed and maintain the set distance from the car in front of you.

    Looking under the hood: Radar-based systems. Lets take a look at one ACC technology: radar-based ACC. Some ACC systems send radar waves that reflect off objects in front of your car. Based on the radar reflection, ACC uses distance, direction and relative speed to detect if the car is within the distance you set. ACC predicts the path of your car and then decides whether any of the vehicles ahead are within your set distance.

    Adaptive Cruise Control In Cars

    Adaptive Cruise Control Explained

    Adaptive Cruise Control , also known as Dynamic cruise control, is an advanced version of cruise control. It is used in modern vehicles to maintain distance from the preceding vehicle. It can control the speed and braking system to avoid collisions. The normal cruise control system can only maintain the speed pre-set by the driver. However, the adaptive cruise control system can accelerate or brake as per the situation, after the pre-set speed.

    In this guide, we will discuss ACC in detail.

    HOW IT WORKS

    The ACC works differently from ordinary cruise control systems. It works on a pre-set speed limit. It adjusts the vehicle speed according to the traffic and preceding cars. It usually works on the basis of sensors that are located at the front of ACC. These sensors continuously monitor the road and preceding vehicles.

    If a slower speed vehicle comes in front of the car it will reduce the acceleration or engage the braking system. Similarly, if a vehicle changes lanes or speeds up, the Adaptive Cruise Control will accelerate accordingly.

    However, if the road is empty it will drive the car at the maximum speed set by the driver. It can be activated at a speed of 30 km/h or above. Whereas, adaptive cruise control with stop and go feature can be activated below 30 km/h.

    TYPES OF ADAPTIVE CRUISE CONTROL

    The ACC is getting modernized with time and new technologies are being used in the system. Following are the different types of ACC currently used in commercial vehicles.

    Cars Under 30 Lakh With Adaptive Cruise Control And Advanced Driver Assistance In India

    A few carmakers recently made headlines by introducing advanced driver assistance system and adaptive cruise control features in Indian cars. Note that even many luxury cars in India do not have these features. Here´s a little lowdown on how these two features work.

    Now regular cruise control helps maintain your car at a set speed without regular acceleration input from the driver. This helps reduce fatigue for the driver on long journeys. However, this is not a very useful feature even on Indian highways, where sudden emerging traffic is always a possibility. Moreover, the feature switches off the moment brakes are applied. But adaptive cruise control not only maintains speed of the car, but it also maintains safe distance from the car in front and behind you without any acceleration or braking input from the driver.

    ADAS also includes a Lane Keep Assist feature, which is different from a Lane departure warning feature. The Lane Keep assist doesn´t warn, it briefly takes control of the car to help maintain lanes while driving. These two features make your journey smoother, safer and enhance your driving experience. Presently, the Indian market consists of only three budgeted cars to have this feature.

    History Of Adaptive Cruise Control

    U.S. News says Mitsubishi first introduced adaptive cruise control in Japan in 1992. This was a lidar-based distance detection system that detected objects that were getting too close. It was labeled as ‘Debonair’ and it was programmed to provide a warning to the driver about oncoming objects. The main difference was that it was the driver’s job to apply the brakes and reduce their speed.

    However, two years later in 1995, the Mitsubishi Diamante featured an upgraded approach to the Debonair called ‘Preview Distance Control.’ Unlike the original technology, this laser-powered system could adjust a driver’s speed by downshifting or controlling the throttle. The driver was still responsible for applying the brakes.

    From the early 2000s onward, big names in the car industry, such as Ford, BMW, Mercedes, Cadillac, Volkswagen, Infinity, Hyundai, Toyota, and Audi, created their versions of adaptive cruise control in their vehicles. These individual features have evolved into a high-tech system with automatic braking and speed control.
