The traffic jam assist can accelerate, decelerate and brake when driving at low speeds to keep pace with the traffic ahead. Traffic jam assist is a type of adaptive cruise control that some cars have. It’s designed to help reduce driver fatigue in stop-start traffic.
Is Adaptive Cruise Control Worth It?
However, like a stood-up date who is all dressed up with nowhere to go, you will not find Level 3-designated highways as of yet. Aftermarket systems provide a taste of ACC and advanced driver assist capabilities. But overall, OEM automaker ACC integration delivers a smoother and more reliable driver experience.
How does Adaptive Cruise Control work?
Radar-based sensors can be hidden behind plastic fascias; however, the fascias may look different from a vehicle without the feature. For example, Mercedes-Benz packages the radar behind the upper grille in the center and behind a solid plastic panel that has painted slats to simulate the look of the rest of the grille. Yes, many modern Adaptive Cruise Control systems come with stop-and-go technology that can bring your vehicle to a complete stop and then resume driving when traffic starts moving again.

The ACC proposed by Kesting et al. partially eliminates the unrealistic behavior of IDM in cut-in situations. However, since the ACC proposed by Kesting et al. inherits the instability of IDM under homogenous traffic flow condition [16]. Moreover, an ACC, which is proprietary to Nissan, was described by Shladover et al. [17]. Since this ACC is simplified representation for computation efficiency in simulation, it is not able to describe the ACC car-following behavior in the field test.

Level 0 (No Driving Automation)
But, what exactly is adaptive cruise control, and how does it work? ADAS adaptive cruise control automates reactions in situations that would otherwise necessitate driver intervention. Without the need for driver engagement, the system can minimise driver fatigue-related incidents more than regular cruise control while maintaining a safe gap from vehicles ahead on the road. For example, if you come up behind a slower moving car, the ACC will automatically slow your speed down to keep a safe distance from the car in front.
It’s no surprise that an automaker obsessed with safety was an early adopter of adaptive cruise control. Volvo was also one of the first automakers to pair the technology with autonomous emergency braking, allowing a car to both automatically follow a vehicle in front and brake if it encounters an obstacle. Volvo’s latest Pilot Assist II system doesn’t need to track a vehicle ahead, can a keep a car centered in its lane, and can operate at speeds up to 80 mph. It maintains a set speed for your vehicle, like a conventional cruise control system, but it also adjusts the speed based on the traffic flow. Better systems can come you a full stop in heavy traffic and continue when congestion lightens. This technology can make cruise control more useful by taking some (but not all) of the workload off the driver.
Adaptive cruise control (ACC) is a driver assistance system that establishes a maximum speed for automobiles and automatically decreases the vehicle’s speed when traffic is detected in front of it. There are systems that can be hard-wired into a vehicle to limit its top speed (a 70mph limit in vans, for example), or there are driver-activated systems. You can set a maximum speed for your vehicle, but you maintain control of the car's accelerator at all times. When you approach your set maximum, the car will simply stop accelerating. Once upon a time, cruise control was the preserve of high-end luxury cars, but as the technology has become more affordable, car makers have rolled it out on more mainstream models.
While the future of autonomous vehicles is promising and exciting, mainstream production in the U.S. is still a few years away from anything higher than Level 2. Not because of technological capability, but because of security—or the lack thereof. Cruise control can trace its origins back to the 17th and 18th century, when engineers developed 'speed control' systems for steam engines.
Understanding ADAS: Automatic Emergency Braking (AEB)
Adaptive cruise control helps drivers adjust the speed of their vehicle. Adaptive cruise control automatically controls the acceleration and braking of a vehicle. They begin with no automation and wrap up with full automation, including vehicles without pedals or steering wheels. 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.

An autonomous car is a vehicle capable of sensing its environment and operating without human involvement. Almost two years ago, Audi (Volkswagen) announced that the next generation of the A8―their flagship sedan―would be the world’s first production Level 3 vehicle. It features Traffic Jam Pilot, which combines a lidar scanner with advanced sensor fusion and processing power (plus built-in redundancies should a component fail). The Society of Automotive Engineers (SAE) defines 6 levels of driving automation ranging from 0 (fully manual) to 5 (fully autonomous). Dean has been part of the Auto Express team for more than 20 years, and has worked across nearly all departments, starting on magazine production, then moving to road tests and reviews. He's our resident van expert, but covers everything from scooters and motorbikes to supercars and consumer products.
By monitoring other vehicles and objects on the road, adaptive cruise control enables a safe and comfortable driving experience. It does so by helping the driver keep a steady vehicle speed at a given moment. The driver can set their preference regarding certain factors, such as the distance to the car in front, driving mode – for example, economical, sporty or comfortable – and others. Together with information about speed limits, road curvature, accidents data and more, these choices influence the automatically selected speed. Subaru’s EyeSight system uses cameras instead of radar, bringing down its cost and making installation of the hardware a bit easier.
Tesla’s Autopilot, GM’s Super Cruise and Ford’s BlueCruise go one crucial step beyond that by allowing you to drive without a hand on the wheel. The GM and Ford systems are geofenced to operate in only specific stretches of highway, whereas Tesla’s system operates more freely (for better and for worse). Tesla also does not monitor the driver’s attention as Super Cruise and BlueCruise do. The Lincoln version of BlueCruise, called ActiveGlide, is pictured in action below. Here’s a rundown of the terms the various carmakers use for ACC, even those that simply call it adaptive cruise control.
Additionally, if dirt, snow, or ice are on the sensors, they won’t work. 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.
