Welcome to the jeepExperts.com In-Depth web page on the WK2 Jeep Grand Cherokee ahead collision wrning plus system. Did we miss something? get in contact with us and tell us!
The Forward Collision Warning Plus (FCW+) system with mitigation supplies the driving force with audible warnings, visible warnings (inside the EVIC), and will apply a brake jerk to warn the driving force when it detects a possible frontal collision. The warnings and restricted braking are meant to offer the driving force with sufficient time to react, keep away from or mitigate the potential collision. The minimal pace for FCW activation is 5 mph (10 km/h).
The major sensors used for FCW embrace the ahead dealing with radar situated within the entrance of the automobile within the grill texture and the ahead dealing with digital camera situated contained in the automobile close to the rear view mirror. The ahead dealing with radar utilizing enter from a number of different sensor to know each driver intent and automobile dynamics. These sensors included steering wheel angle, automobile yaw fee, brake swap standing, and throttle enter. If the system determines the driving force is actively driving and conscious of the environmental situations, it’s going to suppress the warning assuming the driving force is in management. Environmental elements even have influence on the perform together with snow, rain, fog, highway situation and highway slope.
NOTE: FCW screens the knowledge from the ahead wanting sensors in addition to the Electronic Brake Controller (EBC), to calculate the chance of a ahead collision. When the system determines {that a} ahead collision is possible, the driving force will likely be supplied with audible and visible warnings and will present a brake jerk warning. If the driving force doesn’t take motion primarily based upon these progressive warnings, then the system will present a restricted degree of energetic braking to assist gradual the automobile and mitigate the potential ahead collision. If the driving force reacts to the warnings by braking and the system determines that the driving force intends to keep away from the collision by braking however has not utilized ample brake drive, the system will compensate and supply further brake drive as required.
Availability: Optional on the 2014 Grand Cherokee Limited and Overland fashions, Standard on the 2014 Grand Cherokee Summit. Not accessible on Laredo or SRT.
The Forward Collision Warning system is meant to carry out the next:
– If the system detects the collision is probably going it’s going to proceed via the next progressive steps (The system will likely be suppressed if the driving force intervenes.)
- Step 1 Pre-fill the brake system – This brings the brake pads nearer to the rotors to permit faster response time for the automobile to cease.
- Step 2 – Audible and Visual warning (“!Brake!” message within the Cluster together with chimes from the Radio)
- Step 3 Brake Jerk – This is a haptic warning to the driving force in the event that they haven’t responded to the audible/visible warning
- Step 4 Collision Mitigation braking – Apply 1.5 seconds of .3G braking which is roughly 1/3 of the utmost braking functionality of the automobile.
If the driving force doesn’t reply to any of those steps the automobile will proceed towards the thing and doubtlessly influence the thing in entrance. Advance Brake Assist If the driving force does press the brake at any time throughout these steps and the system determines extra brake drive is required to keep away from or mitigate the influence, the system will complement further brake drive as required.
The Forward Collision Warning system will not be meant to do the next:
- The system won’t carry the automobile to an entire cease!
- The system can not account for all driving situations!
- The Active Braking won’t react on stationary licensable automobile except decided by each the Forward Facing Camera and Radar.
- The Active braking won’t react on Street Signs, Guard Rails, Pedestrians, Animals, or different stationary objects. You will obtain an audible and visible alert just for these objects if situations are met.
NOTE: The FCW alerts could also be triggered on objects aside from autos similar to guard rails or signal posts primarily based on the course prediction. This is anticipated and is part of regular FCW activation and performance.
NOTE: It is unsafe to check the FCW system. To forestall such misuse of the system, after 4 Active Braking occasions inside a key cycle, the Active Braking portion of FCW will likely be deactivated till the following key cycle.
NOTE: The FCW system is meant for on-road use solely. If the automobile is taken off-road, the FCW system must be deactivated to stop pointless warnings to the environment. If the automobile enters 4WD Low Range, the FCW system will likely be routinely deactivated.
Radar/Camera Fusion
To cut back the variety of false positives in earlier methods, Chrysler has built-in Forward Facing Camera data with radar data to enhance the robustness of the system.
– These enhancements embrace redundant data to substantiate automated braking on stationary licensable autos that are categorized as Cars, Trucks, Motorcycles, and Trailers.
– The ahead collision warning system will nonetheless present an audible/visible warning solely on stationary objects which aren’t categorized as autos if the situations are met.
– Automatic Braking will likely be supplied on shifting objects with Radar solely classification. This is similar quantity of braking as most ACC braking.
NOTE: The system will not be designed to interchange attentive driving, it’s only supplied as help to the driving force. Please see the proprietor’s handbook for extra data.
Turning FCW ON or OFF
NOTE: The default standing of FCW is “On”, this enables the system to warn you of a potential collision with the automobile in entrance of you when you’re farther away and it applies restricted braking. This provides you essentially the most response time to keep away from a potential collision.
- The ahead collision button is situated under the local weather controls, on the swap panel.
- To flip the FCW system OFF, press the ahead collision button as soon as to show the system OFF (led activates).
- To flip the FCW system again ON, press the ahead collision button once more to show the system ON (led turns off).
Changing FCW Status
The FCW characteristic has three settings and may be modified inside the Uconnect® System Screen:
NOTE: The FCW and energetic braking settings can solely be modified when the automobile is in PARK.
1. Far
- The default standing of FCW is the “Far” setting.
- The far setting supplies warnings for potential collisions extra distant in entrance of the automobile, permitting the driving force to have essentially the most response time to keep away from a collision.
- This setting is designed to offer early warnings per NHTSA (National Highway Traffic Safety Administration) suggestions.
- More cautious drivers that don’t thoughts frequent warnings could want this setting.
NOTE: This setting provides you essentially the most response time.
2. Near
- Changing the FCW standing to the “Near” setting, permits the system to warn you of a possible frontal collision when you’re a lot nearer.
- This setting supplies much less response time than the “Far” setting, which permits for a extra dynamic driving expertise.
- More dynamic or aggressive drivers that need to keep away from frequent warnings could want this setting.
3. Off
- Changing the FCW standing to “Off” prevents the system from warning you of a potential collision with the automobile in entrance of you. The FCW system state is stored in reminiscence from one key cycle to the following. If the system is turned OFF, it’s going to stay off when the automobile is restarted.
Turning Active Braking ON or OFF
- The Active Braking characteristic has two settings and may be modified inside the Uconnect® System Screen:
- On
- Off
- Changing the Active Braking standing to “Off” prevents the system from offering restricted autonomous braking, or further brake help if the driving force will not be braking adequately within the occasion of a possible frontal collision.
NOTE: If FCW is about to “Off”, “FCW OFF” will likely be displayed within the EVIC.
FCW Limited Warning
If the system turns off, and the EVIC shows “ACC/FCW Limited Functionality” or “ACC/FCW Limited Functionality Clean Front Windshield” momentarily, there could also be a situation that limits FCW performance. Although the automobile remains to be drivable beneath regular situations, the energetic braking is probably not totally accessible. Once the situation that restricted the system efficiency is not current, the system will return to its full efficiency state. If the issue persists, see your licensed vendor.
Service FCW Warning
If the system turns off, and the EVIC shows:
- ACC/FCW Unavailable Service Required
- Cruise/FCW Unavailable Service Required
This signifies there’s an inside system fault. Although the automobile remains to be drivable beneath regular situations, have the system checked by a licensed vendor.
| WARNING! Forward Collision Warning (FCW) will not be meant to keep away from a collision by itself, nor can FCW detect each sort of potential collision. The driver has the duty to keep away from a collision by controlling the automobile through braking and steering. Failure to observe this warning might result in severe damage or demise. |
