City Safety, which encompasses all autonomous braking functions, demonstrates Volvo’s unwavering commitment to safety. The latest addition was Automatic Braking at Intersections. Its operation is very useful both in urban areas, with street crossings and dense traffic, as well as at road crossings, where vehicles travel at higher speeds.
This is acknowledged by Lotta Jakobsson, Specialist at the Volvo Cars Safety Center Our studies on the data on these types of accidents show that a significant number of them could have been prevented or mitigated if the turning vehicle had been equipped with a safety system. automatic braking This strategy brings us closer and closer to our goal of no one being killed or seriously injured in a new Volvo.
Volvo City Safety thus detects some imminent dangers while driving to save our lives. One of them is when we are driving on the road and we are going to take another road that opens to the left, but before turning we have not seen a vehicle coming from the front. Another, when we are in danger of colliding with other vehicles traveling in the same direction.
It may be difficult that we do not see a truck driving slower in front of us, but it is easier not to notice the motorcycle or moped driving in front, perhaps very close to the line of the shoulder. In this case, the system can avoid a collision if the speed difference is up to 50 km / h. In case it is greater, automatic braking helps mitigate the consequences of the accident.
Cyclists also benefit from Volvo’s City Safety system, as the car detects any unexpected maneuvers they make in front of the vehicle and can avoid an accident or run over when the speed difference is up to 45 km / h (if higher, mitigates the consequences of it). And even pedestrians can appreciate this set of safety solutions since the car detects who is walking in front of the car and can avoid an accident or run over at speeds of up to 45 km / h (or reduce damage if the car circulates faster).
To prevent these accidents, the City Safety system combines the work of a fast, sensitive camera with highly advanced exposure control with that of radar. The camera is integrated into the upper part of the windshield and works even in very low light conditions. The radar, for its part, detects the objects in front of the car and determines their position, movement and distance. By crossing this information with that of the camera, which detects what obstacle it is, a central control unit assesses the risk and acts accordingly.
If the danger is imminent but can still be avoided without complications by the driver, the car turns on a light signal on the lower part of the windshield and a call sign on the clock panel, to which an acoustic signal is added. When the driver reacts to the warning, the system remains alert and can increase stopping power if it deems it appropriate. And if it does not react, the system can act on its own, autonomously activating the braking at its maximum power. Jakobson concludes by noting that statistics show that about 90 percent of all accidents are caused by distracted drivers.
Because City Safety remains alert, even if the driver is distracted or tired, it helps reduce collision rates considerably. The truth is that we have confirmed a documented reduction of frontal collisions by car, traveling at low speed, after following traffic situations by more than 20 percent Our goal is, of course, continuously extend City Safety’s automatic braking technologies to cover more objects and more traffic situations.
