Although the state of autonomous driving today is Level 2, a few carmakers are on the precipice of Level 3. For example, Tesla’s Enhanced Autopilot, Ford’s BlueCruise, the Mercedes Drive Pilot, and General Motors’ Super Cruise bring the potential for Level 3. A few over-the-air software tweaks will turn the potential into reality. 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. We won’t take you through all levels of driving automation. They begin with no automation and wrap up with full automation, including vehicles without pedals or steering wheels.
Can I Add Adaptive Cruise Control to My Car?
Although the fuel savings were minimal, both claims were accurate. General Motors autonomous car unit, Cruise, has started to offer driverless rides to residents of San Francisco as it moves toward the launch of a full-fledged robo-taxi service. Radar-based sensors can be hidden behind plastic fascias; however, the fascias may look different from a vehicle without the feature.
What Carmakers Call Their Adaptive Cruise Control Systems
It can use radar, laser, binocular computer vision systems, a forward-aimed camera, or some combination of these technologies to track the traffic ahead of your vehicle. It senses when that traffic flow slows or stops, reacting to maintain the preset following distance. Mercedes offers one of the most comprehensive adaptive cruise control and driver-assistance suites of any automaker. Its latest Distronic Plus system can keep up with traffic, but also brake the car to a full stop in stop-and-go situations.

The complexity of adaptive cruise control systems puts them beyond the reach of the aftermarket. Radar-based ACC is often sold together with a precrash system,[43] which warns the driver and/or provides brake support if there is a high risk of a collision. Also in certain cars, it is incorporated with a lane maintaining system which provides a power steering assist to reduce steering input burden on corners when the cruise control system is activated.

The system then assumes control of the accelerator, maintaining the set speed until the driver engages the brake. Every ACC system works slightly differently, says Kelly Funkhouser, manager for vehicle technology at CR. For example, the Hyundai Elantra SEL ($22,795 with destination fee) offers its Smart Cruise Control with Stop and Go in its optional Convenience Package ($1,900). It also includes forward collision warning with automatic emergency braking, Junction-Turning Detection, navigation, wireless phone charging, heated front seats, and more. On the other hand, the same ACC system is standard for the $27,395 Elantra Limited. Is anyone surprised that carmakers can’t seem to agree on a single term for adaptive cruise control?
Multi-sensor systems
ACC systems allow you to set a desired speed until your vehicle encounters slower-moving traffic. Then it will brake to maintain a set distance from the car ahead. Once the traffic starts moving again or if there is no longer a car in the lane ahead, ACC will accelerate to resume the previous set speed. Although ACC systems may take some getting used to, our survey respondents told us they appreciated the stress relief the feature brings.
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. Simple to use, all you need to do is turn on the system in your vehicle, reach your desired cruising speed, and set it.

Installation cost depends on the sophistication of the system and the vehicle model. This is particularly true if you do a lot of highway driving. Moreover, the more sophisticated systems with full stop and start or a low-speed traffic-jam feature work great for city driving. Typically, ACC gets included in a trim level or some sort of optional driver-assistance package on new cars.
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. Not all systems work at low speeds, so drivers who plan to use ACC in slow traffic should check the limitations of any system they plan to buy. These particular systems will often have the words “traffic jam” or “stop and go” in their name.
” We can sort of forgive Mercedes for its Distronic cruise control. Some call it adaptive cruise control as the root and then tack something onto it. 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.
The driver must be prepared to resume control in case of an emergency but otherwise doesn’t have command of the car. That is, the driver’s hands can be off the steering wheel and their attention elsewhere. In addition to following traffic and automatically keeping a car in its lane, Autopilot can execute lane changes with the flick of a turn signal, and negotiate some highway off-ramps. Tesla’s ability to pull data from cars using the system and launch over-the-air software updates means Autopilot has significant potential to improve over time. Like systems available from other automakers, Cadillac’s Super Cruise allows the car to accelerate, steer, and brake without driver intervention on highways. But Cadillac is the only automaker to specifically claim that drivers can take their hands off the wheel.
GPS data can inform the system of geographic features such as a freeway offramp. A camera system could notice driver behavior such as brake lights and/or a turn signal. The systems use lasers, radar, cameras, or a combination of those. If traffic slows to a stop, most ACC systems will bring the car to a complete stop, then bring it back up to speed when traffic gets going again. Others work only within certain speeds and/or might not start to accelerate automatically.
