For the 2015 model year, Chrysler Group’s Full-Speed Forward Collision Warning-Plus system will be available on the redesigned Dodge Charger full-size sedan, the all-new Chrysler 200 mid-size sedan and the Jeep Cherokee mid-size SUV.
Full-Speed Forward Collision Warning-Plus, the latest iteration of Chrysler Group’s most advanced driver-assist feature, benefits from a “unique pairing of radar and camera technologies,” the automaker said.
“Chrysler Group takes seriously its commitment to providing innovative and intuitive driver-assistance features to the mainstream market segments,” said Mark Chernoby, senior vice president of engineering and vice president of the Product Committee. “Accordingly, our engineers seek to develop the most effective means to deliver on that commitment.”
Chrysler Group’s radar and camera technologies combine to determine whether a frontal impact with another vehicle is imminent. The two must agree or the system will not activate. Such redundancy is designed to prevent false-positive readings.
Once Full-Speed Forward Collision Warning-Plus determines a frontal impact appears imminent, the system pre-fills the vehicle’s brakes and transmits two simultaneous warnings to alert the driver that intervention is required. One warning is audible, and the other appears on the brightly lit, thin-film transistor (TFT) display of the vehicle’s instrument cluster.
If the driver doesn’t respond, the system triggers a brief brake application as a tactile alert. If the driver remains unresponsive and the collision risk persists, the vehicle’s brakes are steadily and firmly applied to slow forward progress. This intervention is intended to provide more driver-reaction time and, if there is no response, help reduce crash energy in the event of a collision.
If the driver responds with inadequate brake force, Full-Speed Forward Collision Warning-Plus triggers Advanced Brake Assist. This automatically increases brake force for better performance.
If an imminent collision is detected at speeds below 20 mph, the system may deploy maximum brake force and bring the vehicle to a full stop.
Full-Speed Forward Collision Warning-Plus joins a growing list of autonomous-intervention features available on Chrysler Group vehicles. That list includes Lane-Departure Warning with Lane-Keep Assist and Adaptive Cruise Control-Plus with Full Stop.
