Welcome to the jeepExperts.com in-depth web page on the WK Generation Jeep Grand Cherokee SensibleBeam headlamp dimming system. Did we miss something? Please get in contact with us and inform us about it!
The SensibleBeam system gives elevated ahead lighting at night time by automating excessive beam management via using a digital digital camera mounted on the within rearview mirror. This digital camera detects automobile particular gentle and mechanically switches from excessive beams to low beams till the approaching automobile is out of view. The result’s an clever, high-beam headlamp management system that significantly improves nighttime-driving security. SensibleBeam optimizes using a automobile’s headlamp system so as to present the utmost quantity of sunshine doable for any driving state of affairs.
To make the transition from low to excessive beams and again once more much less distracting and extra aesthetically pleasing, SensibleBeam is designed to slowly fade the excessive beams on and off. However, if site visitors out of the blue seems, similar to when cresting a hill or rounding a nook, the system will instantly flip off the excessive beams.
Low Beams Alone Not Sufficient
SensibleBeam is a significant breakthrough in nighttime driving security as a result of it maximizes using the automobile’s excessive beams. Recent developments in headlamp know-how have centered on making low beams brighter. However, as a result of low beams level downward and illuminate the highway in entrance of the automobile, they’re not as efficient as excessive beams at illuminating obstacles a whole bunch of toes upfront of the automobile. High beams level outward, not downward, considerably enhancing the motive force’s capacity to detect hazards at a better distance.
In addition, it’s simple to “out drive” your low beams. Even average speeds could also be too quick to react to highway hazards as a result of your low beams gained’t illuminate them far sufficient upfront. Studies present that at 50 mph, a minimal whole lamp depth of 75,000 candela (cd) is required to light up the motive force’s ahead view so as to assist make sure that the motive force can see and react to potential hazards within the highway forward.
Drivers Are Hesitant to Use Their High Beams
Drivers, for quite a few causes, hesitate to make use of their excessive beams. In truth, a U.S. Department of Transportation examine discovered that high-beam headlamps are used lower than 25% of the time through which driving situations justify their use.
Why People Don’t Use Their High Beams:
1. They overlook
2. They worry forgetting to modify them off when oncoming site visitors seems, probably annoying or briefly “blinding” different drivers
3. They’re unable to modify them off quick sufficient
4. Complacency
SensibleBeam prevents these issues and ensures optimum use of a automobile’s excessive beams. The system maximizes ahead imaginative and prescient by mechanically turning on the automobile’s excessive beams when no different automobile site visitors is current, and reverting them again to their low-beam depth when detecting both the headlamps of oncoming site visitors or the taillamps of previous automobiles.
Problems with Previous Systems
For years, the automotive trade has looked for lighting options that maximize ahead imaginative and prescient with out producing oncoming glare. Previous “automated” high-beam controls programs abruptly modified from excessive to low beams and didn’t work properly attributable to nuisance switching from non-vehicle gentle sources. They have been additionally unable to successfully see previous automobile taillamps, and couldn’t distinguish many kinds of gentle sources inside an ample time interval.
SensibleBeam solves the problems with earlier programs and has carried out properly in demonstration take a look at drives.

2. Push again on the multi-function management lever as soon as once more to re-activate the system.
NOTE: Broken, muddy, or obstructed headlights and taillights of automobiles within the discipline of view will trigger headlights to stay on longer (nearer to the automobile). Also, filth, movie, and different obstructions (sticker, toll field, and many others.) on the windshield or digital camera lens will trigger the system to operate improperly.
When the SensibleBeam system is enabled, it’s darkish sufficient to justify use of excessive beams, the automobile is shifting over 20 mph, and no different site visitors is current, the excessive beams will steadily activate. When the system detects an approaching automobile’s headlamps or a previous automobile’s back lights, the high-beams will flip off.
Depending on the driving state of affairs, SensibleBeam could fade the high-beams on and off, or management them off immediately. The high-beam indicator on the instrument panel will illuminate as quickly because the high-beams begin to come on, and can stay on till the high-beams have pale off utterly. All SensibleBeam-equipped automobiles, nevertheless, will rapidly flip off the high-beams if the system detects the sudden presence of car lights forward. SensibleBeam doesn’t forestall the motive force from utilizing the high-beams manually. Flash-to-pass remains to be useful with SensibleBeam.
The lighting management swap, positioned on the left stalk, have to be within the Auto place labeled “A” on the stalk. The system can return to guide management by pulling the stalk in direction of rearward. A partial pull will momentarily energy the excessive beams (flash-to-pass). A whole pull will override SensibleBeam. A message will briefly seem within the reconfigurable show to verify. Also, the excessive beams will change from on to off, or off to on, with a whole pull. SensibleBeam will solely activate the high-beams when touring at speeds in extra of 17 mph (27 km/h). If the high-beams are on whereas decelerating and approaching a full cease, the system will flip them off at roughly 15 mph.
SensibleBeam senses lighting situations instantly forward of the automobile. In sure conditions, similar to hills or winding roads, it might be extra snug manually overriding the system as a result of the automobiles in entrance will not be in SensibleBeam’s discipline of view.
