What is active braking / active safety systems?

.

1 describes the basic active braking / active safety system

automotive safety system mainly in two ways: active safety system and a passive safety systems. Active safety systems include ABS, ESP and other electronic equipment, the passive safety system according to the energy absorbing structure of a vehicle body, safety belts, airbags and the like. Today, active safety systems cutting-edge technology has been developed to pre-crash safety system, which is the most typical is active braking system. The world’s first standard on models such technologies is the Volvo City Safety City Safety automatic braking system, in addition, it has a similar equipment on the Mercedes-Benz, Subaru, Lexus like high-end models, the initiative to have the brakes popular trend.

there are statistics show that 75 percent of rear-end accident occurred at about 30km / h speed, and the Volvo’s “City Safety “system, it is these incidents 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.

At present, we can understand that appear on automobile security configuration, representative of active braking technology are the Subaru EyeSight, Volvo City Safety, Mercedes-Benz Pre-safe system, Lexus Pre-CollisionSystem (PCS) Volkswagen Adaptive Cruise Control (ACC), Infiniti Distance Control Assist (DCA). As aThe latest item of active safety technology that can help drivers avoid rear-end collisions at low speed common in urban traffic.

in all the media long test drive, have come to this conclusion: Volkswagen Adaptive Cruise Control (ACC), Volvo and Subaru EyeSight CitySafety the like assistive technology is particularly suitable for driving traffic congestion cities, as urban driving long blockage will make driver distraction, with this function can avoid rear-end after the accident; but when driving in high speed, these active braking technology systems can achieve active deceleration can reduce losses and risks.
