I've got an idea for a predictive type of braking system. The general theory is great, however I am not a Mechanical Engineer at all ... just an idea incubator :tongue2: Anyway ... my idea requires the use of deceleration of the vehicle. Are there typically sensors already on the car that measure the actual rate of deceleration? My system depends greatly on knowing exactly how quickly the car is slowing down - either through applying the brake pedal, emergency brake or simple downshift/deceleration. It's my understanding this information should be able to be gathered from any car with ABS as the ABS system has many different monitors related to braking and deceleration. Can someone tell me if this is true and if so, what these monitors are, what they measure and what unit they use to measure? Useful info would also be how one may tap into this. If you can't provide specifics, I'd be happy to just have better direction. I would outline my whole idea here, but I'd really like to get a prototype and patent it before I go blabbing about it on the internet. I'm sure you understand. Sorry if I posted this in the wrong forum too ... I was trolling around looking for the best place to post and this seemed best.
