does anyone know if its possible to have your car cruze control connected to your jammers. Such that it turns off cruze the instant a threat is registered. This would start decelerating the car much faster than my reaction time. Thus allowing for better, quicker JTK

The concept is great, but each car system functions differently, and needs special programming to allow the jammer take control of the speed and brakes

ALP does have an output that you can use to kill your stereo during an alert so I would imagine there is probably a way with a relay or such to have it control that function if you can get access to the cruise circuit in the car. That said it would have to be a custom type solution as most cars are different.

I don't think automakers will be exposing their speed control systems to remote control by any means, ever. Not intentionally. Personally, I think you'd be nuts to even try working around that.

you might be able to wire up a relay to kill power to the cruise control circuit during an alert... then reset after the alert... as far as taking control of it via another means might be risky. and you would have to see if your cruise control has a dedicated circuit... i would hope that if the circuit loses power the system would shut off...

What does it matter since cruise control disables when you step on the brake. You should be immediately braking once you get a laser hit. Plus, any deactivation of CC before you touch the brakes will really not reduce the speed at all. Maybe 1-3mph

You won't be saved by alerts you don't get.

With caution; this could work. In theory and as a thought experiment;
Jammer alert could be allowed to activate the cruise cancel button.

Here's where I believe there are diminished returns on that effort.
Because vehicles are all trying to be efficient, they tend to remain close to the set speed and slowly decelerate when cruise is cancelled. (Unless there's a hill or extra weight being towed)

Cancelling cruise automatically probably wouldn't accomplish much in 2-3 seconds. Try it.

Activating brakes is a seriously bad idea IMO. Some of the issues to deal with would be: Brake lights, brake modulation, people following too close.

But, there is an interface that can make all of that work more smoothly. An aware and practiced driver. :)

Yes, it is very easy to do! It is called your right Foot on the brake pedal! This device works whether using CC or manually controlling the gas pedal. It also is the fastest safest way to reduce speed!

You could probably go through the OBD++ port. But be very careful.

Easiest way is probably as stated earlier. Applying 12v to the brake pedal switch (or whatever voltage it uses), cancel switch, or a normally on relay (turns off when power is applied).

But human reaction times are about 0.5 seconds registering the alarm and moving from gas to brake. With an automatic, it's not going to slow down as much as you think. In a manual, you might shave a few mph but depends what gear you're in.

To make it effective, as the trend is 4seconds to kill, you'd have to work on the brakes rather than cruise control to make it effective.
I say don't f**k with the brakes man. You get a false or an error, or even a real alert, and you're not paying attention, you'll end up worse off for it and possibly a car up your backside.
Before I brake I often glance in the rear view. I've often hit the brakes and looked behind to see the person behind hasn't noticed and I've had to release it to gain space from the back. Saved my car a few times. You can't guarantee they aren't on their phones texting and not watching. You'll have to check your brake globes are always working, and things like that.
Cruise control is a better option but probably worthless and a waste of time and effort if your car has good roll.

Many vehicles utilize 2 switches on the braking system. One for the brake lights and one to deactivate the cruise control. Keep this in mind.
The cruise switch takes less travel and pressure where as the brake switch needs more travel and pressure.

This is something I have been thinking about, as well...
The BMW cruise control features "braking" with a full down-push on the respective toggle which is very convenient for applying the brake without actuating the brake lights. A constant down-push of the toggle will decelerate the vehicle all the way down to 20 MPH before no longer functioning.

Now, if one were able to discern from schematics or looking at that toggle's wiring, it seems possible to accomplish the braking on an ALP alert. That being said, any alert would actuate the braking and could get very annoying.

Deactivating the cruise control isn't going to do much, maybe shave off 1 mph before your foot gets to the brake anyway. And based on what I have seen in the ALP as far as software reliability is concerned, the last thing I'm ever going to allow it to do is take control of my car in any way.
