When
Active Brake
Active brake function is a vehicle traveling in the normal case of non-adaptive cruise, a dangerous situation such as a vehicle can encounter unexpected active itself produce a braking effect so that the vehicle deceleration (the vehicle is provided with such a function, but does not necessarily stop the vehicle completely brakes) to enhance the safety of driving technique. But now various car manufacturers are not uniform nomenclature of this technology, such as Toyota’s Pre-Crash Safety system called Pre-Collision System, referred to as PCS; Honda’s CMBS (Collision Mitigation Brake System) and Mercedes-Benz pre-safe system, etc. .
City Safety system
City Safety system (City Safety) was introduced by Volvo Cars crash technology, City Safety as a new active safety technology it can help drivers avoid rear-end collisions at low speed common in urban traffic. Volvo Car Corporation estimates half of this technology can avoid rear-end collisions, can maximize avoid losses.
“Volvo” City Safety “system.”
works
there are statistics show that 75 percent of rear-end accident occurred at about 30km / h speed, and Volvo of this “city safety” system, it is these accident nemesis: when the vehicle speed reaches 30km / h, the system will automatically start, by monitoring traffic conditions lidar system on the front windshield, especially in the case of 6 meters before the front. The current car brakes, stop, or when there are other obstacles, the system will first automatically force on the brake system to help the driver make shorten the braking distance before action; or it can adjust the steering wheel to change the vehicle travel path to avoid obstacles. Of course, if the distance is already very close to the obstacle, the system automatically without the need for an emergency brake operation by the driver.
“Volvo City Safety Detailed”
According to Volvo, said analysis to calculate the speed of the system up to 50 per second times, can accurately analyze accordance with aspects of distance and vehicle speed, the brakes need to be able to avoid accidents at what time. And the system can be used normally during the day and night, however, and some other radar devices, as in fog, rain and snow is going to be subject to certain restrictions.
