Rear parksense vs rear cross path detection?

I'm debating getting the AT group package as the cross path and blind spot monitoring has my eye.

However is there much difference between rear parksense and rear cross path detection? Or difference in responsiveness?

Thanks

Re: Rear parksense vs rear cross path detection?

Rear cross path can alert you if a car is coming across your path before you back out of a parking space. Very helpful, especially if parked next to larger vehicles that you can't see around. Rear park sense just beeps as you get closer to something as you back up. Blind spot monitor is awesome also. I would definitely recommend getting the option.

Ok thanks. I can disable the other auto brake features through uconnect correct that comes with this package on newer 2014/2015's?

Thanks

Re: Rear parksense vs rear cross path detection?

I don't know about the disabling of autobrake, but I sure wouldn't! While there is an occasional false positive in my FCW on a sharp curve with a guard rail and just above a certain speed, that feature kicks in well before I can get my food on the brake fully when there really is a need to stop quickly. It's a head-start system that can give an edge in avoiding a rear-end collision when traffic in front of you suddenly hits the brakes. Obviously, that's a subjective opinion and yours may be different.

Re: Rear parksense vs rear cross path detection?

I wonder if FCW is self learning,mine does not sound off as often as it used too at false sightings.

I don't think it is because I have one place about 1/2 mile away that gets the most "falsies". It seems to be speed sensitive in that respect and sometimes the angle I take into that curve.

Re: Rear parksense vs rear cross path detection?

That, too, 14'....way too many pedestrians these days just love to walk behind vehicles with the backup lights on. Proves beyond a doubt that Darwin had the right idea...

In addition to the above, there is an inherent difference in the technology behind the features. The Parksense system uses short range ultrasonic transducers. They can only detect proximity and only a few feet away. The cross path sensor system is actually two mid-range Doppler RADAR transceivers located at the back fenders. They are highly sensitive and can easily detect human size targets at distances of 20-30ft. As those are Doppler devices, they can differentiate a moving object perpendicular to the vehicle axis. This system really makes up for the limited visibility you have in the JGC and helped me avoid numerous close call situations. The whole Bosch driver safety assistance system in the Jeep (long range radar FCW/ACC, mid-range cross path radar sensors and the front multi-purpose camera) is probably one of the most invaluable features in my vehicle.

Re: Rear parksense vs rear cross path detection?

I definitely vouch for the fcw and rear cross path detection. On numerous times there's been a pedestrian walking or a car coming that it's alerted me to that I'm sure would have been a collision. I live in the dc metro area and people here drive way too fast through garages.

The fcw saved me from one certain accident on the hwy. I was switching lanes and did a quick look to my blind spot and the car in front slammed on its brakes. Fcw kicked in and I was able to stop within inches, which would have also been an accident if not.

Makes me sound like a bad driver but I'm not-
