Enabling Pilot Assist and Adaptive Cruise Control

[IMAY2023]

I don't remember the exact years / models but Volvo had a front radar on the grill for acc.  With intelliSafe launch, volvo replaced the radar with camera under the rear view mirror both for lane keep assist and ACC/ PA  "shooting 2 birds with 1 stone"  

This actually has brought exactly the limitation we are all mentioning. " Camera does not recognize the changes fast enough like the front radar therefore cannot react on it" 

I'll give another example. 
Many times on the road while ACC was following the car normally according to set distance, the car in front of me, pulls over or changes lane (to right or left wouldn't matter) for any reason.  The car icon on ACC display disappears thinking the road is free and my car accelerates although there is another car in front of me.  The problem is camera locked on the previous car that changed the lane and it takes time to lock on the second car. Many times especially in city, I have to hit the brakes my self because drivers always move to more free lane when approaching to traffic lights.  Well, we all do it, and many times we do it suddenly. 

The only mitigation I found for this, increase the following distance to max, it's annoying in the city traffic 40mph but that would give enough time to Camera to lock on the second car.  

I think this is exactly why, volvo returned the front radar with 2023 models.

I think you’re thinking about Tesla. They’re the ones who got rid of radar in favor of a full camera implementation.

Volvo so far has been radar all the way along with camera for lane detection, signs etc.

No, VOLVO S60 move the integrated radar from the Camera location to the front pumper. from 2023+ models. 90 and xc60 series have this from 2022+ and XC40 2021+ .   Forward aimed Radar (FLR).   Some modules are used for multiple peeresses such as back corner sensors are used for BLIS and Cross Traffic Collision mitigation when backing up.   I don't know if VOLVO uses FLR for both collision mitigation and add  support to ACC.  Some models also have front corner radars (F. cross traffic).
