1. The collision warning system
According to the survey research, in all known accidents in rear-end accidents accounted for one-third of the total. Consequently, Volvo Car Corporation in solving the problem of rear-end collisions Furthermore, the introduction of new Collision Warning with Auto Brake (Collision Warning with Auto Brake). The new system can reduce the maximum possible speed at the time of the collision, reducing the risk of injury to both the occupants in a collision.
compared with the 2006 launch of the radar collision warning system with brake assist function based on the new Collision Warning with Auto Brake functions on a technical level and on a higher level, which is based on radar detecting cameras and front of the vehicle. The warning system uses the Data Fusion (data fusion) techniques, the information obtained from the radar and camera in conjunction with the analysis of more effective role. When the collision approaches, the accuracy of the information sufficient to achieve the car automatically determine and automatic braking. The system is set in radar and cameras to enable mutual recognition in critical condition when the automatic braking.
If the vehicle belt warning system of approaching the vehicle in front and the driver does not pay attention when located in the red warning light will flicker on the windscreen and audible, alert the driver to take action. 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 is not braking systems found embodiment imminent collision, the brake is activated.
Function
automatic brake function is to reduce the impact speed as much as possible, thereby reducing the chance of injury two vehicle occupant. For example, if the collision speed from 60 km / h to 50 km / h, the impact force will be reduced by about 30 percentage, it is sufficient to determine the occupant is injured or slightly injured. In some cases even the automatic brake function RAHelp entirely avoid a collision.
