June 26, 2014 , Auburn Hills, Mich. - Full-Speed Forward Collision Warning-Plus is the latest iteration of Chrysler Group’s most advanced driver-assist feature, which benefits from a unique pairing of radar and camera technologies. This affords greater precision and reliability than those systems that employ singular solutions to object-detection.

“Chrysler Group takes seriously its commitment to providing innovative and intuitive driver-assistance features to the mainstream market segments,” says Mark Chernoby, Senior Vice President, Engineering and Vice President, Product Committee. “Accordingly our engineers seek to develop the most effective means to deliver on that commitment.”

Chrysler Group’s radar and camera technology combine to determine if 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 more prevalent with competitive systems that use either radar or camera technology.

Once Full-Speed Forward Collision Warning-Plus determines a frontal impact appears imminent, it 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 is boldly displayed on the brightly lit thin-film transistor (TFT) display of the vehicle’s instrument cluster.

If there is no driver response, the system triggers a brief brake application as a tactile alert. If the driver remains unresponsive and the collision risk remains, 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 Advance Brake Assist, which automatically increases brake-force for improved performance. However, if the driver has not responded, the collision risk remains, brakes will be automatically applied to slow the vehicle. This helps reduce crash energy.

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.

For model-year 2015, Full-Speed Forward Collision Warning-Plus will be available on the redesigned Dodge Charger full-size sedan, the all-new Chrysler 200 mid-size sedan and the acclaimed Jeep Cherokee mid-size SUV.

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.
 
The following is a comprehensive glossary of key safety, security and advanced-technology features on 2015 Chrysler Group vehicles:
 
Driver warning and assist, chassis control and brake systems
 
  • Advance Brake Assist: If inadequate force is applied to brakes in response to signal from Full-Speed Forward Collision Warning-Plus, Advance Brake Assist automatically increases brake-force
     
  • Adaptive Cruise Control-Plus with Full Stop: Helps maintain distance from vehicle ahead; under certain traffic conditions, system can bring vehicle to full stop without driver intervention
     
  • All-speed traction control system: While driving, helps keep wheels from spinning during acceleration from a stop or at speed by applying brakes alone or in combination with engine torque limitation
     
  • Anti-lock brake system (ABS): Senses and prevents wheel lockup, offering improved steering control under extreme braking and/or slippery conditions
     
  • Blind-spot Monitoring (BSM): Uses dual ultra-wideband radar sensors to aid driver when changing lanes, passing or being passed; blind-spot vehicle presence noted via illuminated icons in side-view mirrors and driver-selectable audible chime
     
  • Brake assist: System applies maximum braking power in emergency braking situations, minimizing stopping distance
     
  • Brake-lock differential system (BLDS): Allows the vehicle to maintain forward motion if one or two wheels lose traction by selectively and aggressively applying brakes to the spinning wheels
     
  • Brake-throttle override: Standard-equipment on every Chrysler Group vehicle, it allows driver to stop the vehicle when throttle and brake inputs occur simultaneously; electronic throttle control also reduces engine-power output
     
  • Brake/park interlock: Prevents transmission from being shifted out of “Park” unless the brake pedal is pushed
     
  • Brake traction-control system (BTCS): Helps to keep wheels from spinning during acceleration from a stop or during slow speeds by applying individual brakes to the slipping wheel(s)
     
  • Electronic brake-force distribution (EBD): Optimizes stopping distances and control under all vehicle loading conditions by regulating braking pressure, front-to-rear
     
  • Electronic Roll Mitigation (ERM): Uses input from electronic stability control (ESC) sensors to anticipate potential rollover conditions; applies brakes individually and modulates the throttle position to help driver maintain control
     
  • Electronic stability control (ESC): Enhances directional control and stability of vehicle in various driving conditions; activation occurs when steering-wheel angle differs inconsistent with vehicle; automatically reduces throttle input and/or selectively deploys brakes to counteract oversteer or understeer
     
  • Full-speed Forward Collision Warning-Plus: Radar and camera technology combine to determine if frontal impact appears imminent; if so, system pre-fills brakes, then transmits audible and visual warnings for driver to intervene; no driver response triggers brief brake application as tactile alert; if driver remains unresponsive and frontal collision risk remains, brakes are applied to slow vehicle before impact; system may bring vehicle to full stop if imminent frontal collision detected at speeds below 20 miles per hour
     
  • Hill-start Assist: Assists drivers when starting from a stop on a hill; maintains brake pressure for short period of time after driver’s foot is removed from the brake pedal; if throttle is not applied within short period of time thereafter, brake pressure will be released

  • ParkSense Parallel/Perpendicular Park Assist: Features ultrasonic sensors on the bumper to find and guide driver into parking space; guidance system automatically controls the steering angle while driver controls gear position, brake, and accelerator; parallel parking possible on either side of the car; to accommodate perpendicular parking, vehicle is backed into the space
     
  • ParkSense rear park assist systems with stop and release: ln reverse, at low speeds, ultrasonic sensors detect stationary objects; if imminent collision is detected, system will provide momentary, autonomous brake pulse; below 4.4 mph, system will bring vehicle to a stop before releasing

  • Rear Cross Path (RCP) detection: In parking-lot situations, warns drivers of lateral traffic when backing out of parking spaces; automatically activates any time a vehicle is in reverse gear; driver alerted of approaching vehicle(s) via illuminated icons on side-view mirrors and driver-selected audible chime
