Sounds a lot like a Tekonsha Prodigy trailer brake controller, it uses some nice accelerometer technology. Don't know how much an accelerometer costs which may be cheaper. Only thing is you would have to leave it on all the time which might drain your battery if you connect it to constant 12v to use with EOC. Or maybe connect it to a timer that will leave it on longer than your longest EOC then shut off. If you don't EOC, then connect it switched with ignition and call it good.
