Adaptive cruise control is one of the first steps in moving towards autonomous driving vehicles, as it allows the vehicle to regulate speed and braking on the highway to maintain a set following interval behind the detected car ahead. Today’s video looks at how Honda implements this system on their vehicles, as well as how Collision Mitigation Braking Systems work. Both systems rely on a millimeter wave radar as well as a monocular camera to detect objects ahead. So how does adaptive cruise control work?
The primary purpose of the system is to travel at the speed selected by the driver, just like traditional cruise control. However, if the vehicle detects another car in front of it that is traveling at a slower speed, the vehicle will reduce its speed to match that of the detected car and a then maintain a selected interval behind the car. The system works by emitting radar waves which bounce off of vehicles ahead and return to the unit. This informs the system of the distance between the two vehicles; changes in that distance inform the system of the vehicles’ relative speeds. So how does the Collision Mitigation Braking System work? The goal of the system is to alert the driver if a collision with a detected vehicle is likely, and then to apply the brakes to reduce the severity of a collision if it’s unavoidable. The system scans up to 330 feet of the road in front of the vehicle and works in three stages if the driver begins to come close to a vehicle detected ahead. Is the kind of technology you’ll be looking for in your next car purchase?
Volvo has always done things a little differently than BMW and Mercedes. Rather than hold back updates and release them all in “mid-cycle refreshes,” Volvo prefers to let the changes dribble out slowly year after year.
For more than a century people have been using cars, trucks and other personal vehicles to transport themselves, other people and goods from one location to another. In fact, the motorized vehicle went from being a luxury to a necessity in many parts of the world where public transportation and other options are limited. As a result of this dependence, it’s vital the automobiles on the road are kept in good repair. The work needed to do so has changed a great deal since the first cars hit the road, and is likely to continue evolving along with the rest of the industry.
