Cruise Control?

I need an engine throttle/ speed cruise controller. I have plenty of Hitec digital servos to use for this so that’s what I want to use.l that way i can program direction, speed and travel limits. My problem, I know nothing about the electronic and programing side to make the servos move. Is there someone out there that can help me with this? program, write software, mostly. I can build the circuit boards and buy all the supplies and make it worth your time. There are comanys making these for what i need. But they are in the $1100 range.There is a few different way I have thought about this working and I want to doo it the easiest way possible. Speed set ranges with be between 5mph-20mph.

1: GPS speedometer/ servo controller, with three dashboard buttons. One for set, resume, and stop. Set button: saves and sets the speed until the power is shut off from the unit. Resume button: controls the servo to resume the preset speed weather it’s from a dead stand still, or over speed so it slows the throttle. Stop button: zeros all controls to the throttle servo, but does not kill the saved preset.

2: portable device app. Use the phone GPS to control the servo via Bluetooth control. All the buttons will be in the app. Will fail safe servo zeroing for and weak signal warnings or automatic servo zeroing if the single acts funky. Device will never be more than 2ft from the receiver.

3: RPM control. Everything the same as #1 except I use the RPM to control the speed instead of “physical distance in time” as with the GPS.( no transmisson, so there will be no gear shifting with hight RPM? This can be done with the signle wire from the ignition coil, or optical or magnetic crankshaft senors.

Hi Brady3d,

That’s a complex and dangerous project which should not be controlled by simple R/C type components.
It will require a lot of research and development on your side as we cannot provide consulting for such customer project.

Best regards,

Depending on the country you’re in and if this is something for the road you have to comply with certain bits of legislation. In the UK I’m almost 100% that cruise control MUST be calculated from wheel speed not RPM or GPS. It will also need to control the ABS systems as well as engine control so it’s not quite as simple as you’d think but it all depends on what it’s for.

If it’s for something like a pedelec bike or recumbant then it’s not prone to the same laws as cars and is pretty simple to control plus you can add in a simple kill switch for it really but if it’s a car I’d be really, really careful because a 1.5 ton car even at 10mph can cause a whole world of hurt.

I dont mess with cars. Its for a boat. Vibration moves the throttle handles so it’s only set perfect for a minute or two before it moved its way back to idle.
