So.... Endless ride, how we doing?

An accelerometer could come in handy here.

I want to stay away from the need of extra components for the time being until it’s absolutely necessary. Shit I wish @Lee_Wright did a mellow break down to make sure they’re not using some sort of accelerometer to pull it off.

The very worst case is this feature will only support the VESC 6, Unity and StormCore since they have populated 3-axis accelerometer and 3-axis gyro (which is used really nicely in the VESCT TOOL Logging from what I’ve seen).

@Bavioze

i think @Jamie42 created almost the perfect mode, dont know if he shared it or something though.

After doing so stalking (just went to the old forum and see which GitHub he forked I found this:

GitHub - Jamie4224/FireFly-Nano-Remote: A remote used to control an electric...

His explanation of how it works for future reference:

@Jamie42

Thanks for the pointer @Bavioze

Here’s my approach to it:

I modified the FireFly Nano software to include an “endless” mode. Here is how that works:

1. Enable it through the menu on the remote.
2. Push 13 km/h+ for 2 seconds
3. The board goes into cruise control. This means that the speed will be kept at which yoh were after pushing faster than 13 km/h for 2 seconds. E.g. the hardest you can push is your max cruise speed.
4. The board will cruise for 20 seconds
5. The board will go into “coasting” mode, waiting to slow down till the speed is lower than 13 km/h.
6. You can push to activate cruise again, step 1.

While this is activated you still use your remote, telemetry and the current state “cruise”, “pushing”, “coasting” is visible. But, you can’t push thw throttle. When you brake the board disables cruise immediatly and goes into coasting and brakes as hard as you push the brakes.

Speeds and times can be adjusted ofcourse, stoppihg because of a “current spike” activated by a foot on the ground is also possible.

@Jamie42

Forgot to mention; There’s a max speed setting. When you reach this max speed to board goes into ESTOP mode where brakes are gradually applied. You can set the strenght of this feature.

Edit: Remote is always the master override. When you brake on the remote, “pushing” mode can’t be engaged.

Edit 2: For me this is a police mode. Board works as normal, throttle available. When I see police I switch to endless quickly. The police here accept this and see it as an electric supported bike as you first have to do something yourself, like the electric bike.

Seems like he made some strides towards endless mode recently:

From. quick glance , I’m unsure

and it works like so:

Endless ride - when remote is off and speed is over 12 km/h for 3 seconds,
cruise control will be activated when speed drops below 12 km/h.
Slide the board backwards while standing on it or foot brake
to produce a spike in the current and stop the board.

From looking at this receiver.cpp file he takes any speed above 23km/h as downhill

and applies a braking force of 127 / 5 * 0.1 to the throttle until it’s stopped

I have to look more into it but this mode doesn’t seem like a 1:1 endless ride implementation that I’m going for.

It’s a nice implementation of the timed cruise control concept me and @Brenternet where thinking of earlier. Any thoughts on his implementation? Auto Braking should only occur in the PUSHING state that can only be entered into if the current speed is past a certain RPM. If it’s within an okay region (past the pushing state threshold but under the pushing state speed limit) and the throttle aint being messed with, then the ENDLESS MODE state will start its timed cruise control. After a certain amount of time passes (or if the throttle is messed with) it will enter the Coasting state until it reaches back under the pushing speed threshold.

One thing though is I don’t get how a user will be able to push during the coasting state. It seems that the user will have to wait until the Coasting state goes back to the normal state to have their pushing accepted. Also instead of pulling back the speed to the max push speed, it opts for braking, which I guess can work if you set a high enough limit but can get annoying if the limit is low and brakes while you’re trying to push on flat land.

@Jamie42 any insight into your implementation?
