Fiat’s City Brake Control safety system, which automatically applies the brakes to avoid collisions and is active at speeds up to 30 km/h (19 mph) has won the Euro NCAP Advanced 2013 award.
Optional on Fiat Panda and 500L,the innovative active safety system detects the presence of vehicles or obstacles in front of the car and automatically applies the brakes if the driver fails to do so in order to avoid the collision or to reduce its consequences.
Fiat designed the City Brake Control system to provide assistance in city traffic and is always on when the car is moving at a speed from 5 to 30 km/h. Activated whenever the engine is started, the system can be deactivated and reactivated as the driver prefers.
The system uses a LIDAR (Light Detection And Ranging)-type laser sensor located on the upper part of the windshield to interface with the ESC (Electronic Stability Control) system. Depending on certain parameters (such as road surface conditions, vehicle dynamics and trajectories, position of obstacles and condition of the tires, etc.), by cutting in the system can completely avoid or mitigate the consequences of a collision (Collision Avoidance or Collision Mitigation).
The device integrates three functions: Automatic Emergency Braking (AEB); Prefill; and Brake Assist. While respecting the wishes of the driver who remains in full control of the car, the AEB activates emergency braking when a collision appears inevitable and the driver fails to react, thereby actually anticipating his/her reaction.
The Prefill function instead prefills the braking system to provide a quicker response both when Automatic Emergency Braking system cuts in and the driver brakes. Brake Assist, on the other hand, recognizes emergency situations and—if the collision becomes more imminent—the system makes hydraulic brake assist function more sensitive, thus the braking pressure is boosted to provide a shorter braking distance.
