What is pre-crash safety system?

pre-crash safety system can automatically detect obstacles in front, the estimated likelihood of a collision. If the system determines that a collision is very likely, the siren will sound. The system can also automatically adjusted by a series of safety systems: pre-crash brake assist system, emergency steering assist system, Vehicle Dynamics Integrated Management system as much as possible to avoid a collision. If the system determines that a collision is unavoidable, it will advance a front seat belt to tighten, the brakes start to reduce the maximum injury.

Collision warning system

2.FCW before

Forward Collision Warning (FCW) forward collision warning system can be monitored by the radar system timing ahead of the vehicle, determines the distance between the vehicle to the preceding vehicle, and relative orientation speed, when there is a potential risk of collision warning the driver. FCW system itself will not take any action to avoid a collision or braking control of the vehicle. Detailed

3. Benz PRE-SAFE system

Benz PRE-SAFE safety early warning system, also called pre-Security. The accident showed that: most of the traffic accident, from discovery to the actual situation of impact, nearly one-second time interval, and the existing security systems, such as airbags, seat belt tensioners, just a thousandth of a second to start up. Time interval sufficient to initiate a more secure preventive measures to protect the safety of passengers.

PRE-SAFE safety warning system through the ESP and BAS sensors to predict danger and triggers preventive measures to protect the driver and passengers. Driving in, due to oversteer or understeer generated slipping hazard, PRE-SAFE safety warning system will be activated, such as driver and front passenger seat belt can be pulled back by the electric security retractor tension. Once the strike is unavoidable, this feature ensures that the front airbags start, the front occupants are sitting in the best position of protection, so that the airbag play better protective effect. And, PRE-SAFE system can be restored in advance over the front seat to state: if the seat is too far forward, PRE-SAFE system to automatically move back; Meanwhile, if the inclination of the seat back does not apply, the system was adjusted to be the best angle. These seats built by a motor driven mechanical devices is completed. When the vehicle starts to slip, sunroof will automatically shut down. After the danger, can pull back the seat belt retractor will be restored to its original settings, sunroof will reopen.

4.PCS pre-crash safety system

As long as the vehicle starts a PCS will run automatically, continuously detect obstacles in front of radar, the system detects when there is an obstacle within a safe distance, and determines when possible with a collision, an alarm will sound, and tighten the front seat belts. If after alerting the driver has not respond, the system determines when a collision is inevitable, the brake is applied will be appropriate, as far as possible to reduce the collision damage.

in order to secure known for Volvo,Its own pre-crash safety system, as CWAB (Collision Warning with Brake Support)

Volvo CWAB camera system, while detecting radar, the radar 150 is responsible for detecting the preceding vehicle range, the photographing lens in the meter is responsible for vehicle dynamics within 55 meters ahead. When too close to the vehicle in front or middle of the road when a pedestrian, will pass similar brake lights warning lights to alert drivers attention. If the risk of collision alert is still increasing, the brake support is activated. Brakes can shorten the response time, the pre-filled hydraulic braking pressure enhancement, in the case of not sure that the driver brakes hard effective braking can be realized. If the driver does not brake and systematic implementation of the foreseeable impending collision, the brakes will be activated automatically take braking measures.
