TSDZ2 OSF for all displays, VLCD5-VLCD6-XH18, LCD3, 860C-850C-SW102.
- Thread starter mbrusa
- Start date
I think the TSDZ2 has a small engine with weak cooling. I see the maximum constant power somewhere on the border of 250W. In the short term, maybe 750 W, but I quite doubt the dimension of the gearbox. I have a temperature limit of 70C and an off limit of 85C. Power limited to 460W and I have no problem with a cadence of about 70 to warm the engine on a plane to this limit. about 10km. Later it starts to limit me, is it normally such a fairly fast warm-up? I'm not even talking about going uphill. assist only 3 on hybrid. Otherwise I like this engine. :thumb: We could share our settings together, it could help others.
The previous version of the firmware with similar settings worked well even in the most difficult conditions. I think the problem of Mosfeet's burnout is in the PWM frequency. At the time of the burnout of the controller, the load on the engine was not large. I don't know exactly what changes were made in the new version. But I think that too high a PWM frequency can cause combustion..

You are right. Setting the limits to 20A 900W doesn't mean that they will be used, so could work well, but as said the controller hardcoded limit is 18A, so OSF 20A limit will not work, it should be lower than 18A for effectivity.Lii said:
I too think that the catastrophic failure has to do with (wrong) timing. But it is strange that the only the stock version of OSF has this.
No complains with other display versions or older mspider65 BT version.
According to the mosfet datasheet, the current can be much higher than 20A. The main limitation can be the motor winding, which will get very hot. But this will only work at a relatively low PWM frequency. At a higher frequency, the mosfet will not have time to quickly open and close, it will start to heat up. At some moment, one key in the pair will already open and the second will not have time to closeing. The characteristics of the opening and closing speed of these mosfets are not very fast.

Assuming that cruise mode is enabled how does one actually engage the function whilst riding with VLCD5? The manual is silent on that detail.
You can enable cruise mode only with display, not with configurator.raylo32 said:
enable:
Level 3 - 2+2+2 clicks, wait E04 stop flashing
disable:
choose assistent mode you want, for example:
"power assist"
Level 2 - 2 clicks, wait E02 stop flashing

OK, I knew to enable it in the menu (but that is one parameter that I never see the digit change to "1", it stays 0. Maybe I need to be moving for this to take??) I had assumed, apparently wrongly, that there would be a one button 1-click or hold method to actually engage it that would be less distracting whilst riding and that activating a brake would drop out of cruise back into the previous mode (I am using Hybrid). Looks like this is not going to be very useable after all if I have to keep going deep into the menus just to turn it on and off and again to get back to my preferred mode.
I saw a youtube video where they engaged cruise by holding down the "down" button for a long press. but I am not sure what firmware that particular TSDZ2 user had.

Yes, it was a cruise control demo.
So the way you describe it the bike will keep the cruise speed up until I change the mode again or hold down the brakes? I mean I can always cut the motor out and slow with the brake but when the brake is released I would still be in cruise mode and the bike will accelerate? This sounds very dangerous.

This link says to hold down the power button to activate cruise. This is on a 2019 version of OSF as near as I can tell. Probably not the VLCD5 back then since the OSF has only more recently been ported to the OEM displays.
And BTW, I have walk assist off. I don't see any need for that function. If I can't push my bike I shouldn't be on it!

I do have brakes sensors installed and enabled. I haven't tried this on the road yet, I was just trying to enable the function on the work stand to be ready to try on the road. But I see now why that failed and why I don't see the status digit change.
What would be really nice... and perhaps impossible with this particular hardware?... is to program this to work like in a car with an easy way to engage whilst riding with one operation of a button at current speed, and disengage with tap of the brake... without affecting the base pedaling assistance mode.

"Yes, but you only can enable "cruise without pedaling" if you have "brake sensor" enabled.
Normally you have to pedal a tiny bit.
If you stop pedaling without brakes the motor stops too."

In EU countries it is forbidden to have an ebike without pedaling, like with a throttle or cruise control as you propose.raylo32 said:
Such a bike is from another category (small motorcycle) and for that you need a registration, special ensurance, safety additions and a vehicle approval by the goverment.
In some countries they check on regular base ebikes by the roadside for that and check too if the speedlimit of 25km/h can't be changed by the user. (that is why I like the (hidden) streetmode off

Well, you pretty much have that cruise function now in OSF... except that it is exceedingly cumbersome to engage... and since it takes you out of your base riding mode, exceedingly cumbersome (and dangerous looking through the menu for the desired assist mode?) to disengage. But the speed maintaining aspect, which is what the regulators might object to, is there if it is enabled.

I guess that is better than poring through the menus. I can't see using the cruise. All this menuing... and/or power cycling the motor would be just too distracting unless one knew he had, say, 10 miles uninterrupted running ahead. And when do we EVER have that?

And hey, I am NOT busting the developers' chops. They are doing great work... and there may be some hardware and/or software reason the cruise operation has to be this way. It's just not a rider friendly function that can quickly and easily engaged and canceled depending on constantly changing riding conditions.
This is just relative, because you setup your desired default settings with the configurator and use only some other settings for example on road or off road or disable streetmode on the road.raylo32 said:
If you have some practice with menu handling on the display it isn't that bad.
Only as a starter it is overwhelming to click so many times to change something.
For XH18 and Vlcd5 that clicking can be done easy and relative fast, but with Vlcd6 you need to push the button 2 seconds everytime.
if you want easier acces to different modes, than a choice for 860C or BT interface with smartphone should be better.

Sure you get better at it. But no matter how good you get it seems totally unnecessary and unnecessarily distracting to deal with whilst underway. Unlike most all the other parameter selections this one really should be a heads-up function to be safe and useful.... SINCE YOU ARE MOVING! Just like in your car. IMO.
Elinx said:
I have tried the cruise mode a few times with XH18 (level switch is a rotating handle), but with level 0 or stop pedaling the bike stops. It didn't feel dangerous for me.raylo32 said:
Speed up from level 0 to level 4, stop pedaling and go to level 0 is almost like a throttle

What you said is the crux of this...I am sure at some point I will "try" this feature. But, again, IMO it is a novelty feature and isn't going to be very useful, and IMO, not as safe as it should be. Takes only a split second to go off a bike path into a ditch or less of a split second to hit a road curb whilst interacting with the screen. Not to mention the inconvenience when you want to go back to the default mode. Why not just hold a current speed at the touch (or 2?) of a button and release it with the next brake tap? What could have been... Oh, well.
