New option for self cancelling turn signal (TSCU)

[Guest]

Looks like this new company is coming out with a unit. My left sometimes works and my right almost never. Took a look at my box today and cleaned up some of the corrosion but not much different so I am looking at options. Not sure why this feature is not on all new bikes when it has been around for decades on my bike

Nice concept, but the website design makes it hard to follow what's happening and how it works.

For about $100, you had really better WANT to have cancelling signals.

In decades of actually using sefl-cancelling indicators, I found the timer aspect was the most important, with distance sensing being nice to have, but sometimes both of them actually cancelling too soon or even too long. No system is perfect, and it can't mind read, let alone read the traffic or road for the rider.

In view of that, I see a simple timer would address at least 90% of the self-cancelling needs and would be trivial to cost and fit.
A timer will always turn off - it reverts to off, so can't leave signals flashing, and is inherently fail-safe. No need for distance,angle, throttle, load, speed, etc - all that is so much extra complication for the sake of having it, and really if the rider is such a muppet he depends on the machine doing his thinking for him, he really shouldn't be out on a bike.

I tried a while back and there seemed to be general apathy toward a lighting controller. Granted I was looking at it as a SSPB add-on because there just did not seem to be enough interest in this type of stuff. I'm not sure if the M-unit has a turn signal cancel or not? All you need is a speed input and control over the blinkers.

Wouldn't it also be nice if CARS had self-cancelling signals?

The first bike that I remember having self-cancel was the '76 Yamaha XS750. Its system was based on time and distance and worked decently. Many bikes since then have had one refinement or another of that system, but I have yet to see a car that works on either. The only cancelling feature on cars is movement of the steering wheel, which means that you can turn on your signal in Miami, it will still be flashing as you go past New York.

My GS850GL has self-cancelling turn signals and I like them quite a lot. One of my favorite features of the bike, actually. One that I always missed when I had the 750E. The unit is very simple, it turns off the signals after a certain distance, and presumably once the bike has reached a certain speed. I find that this works really well. My main complaint is that sometimes they will turn off too soon while traveling down a long left turn lane. I remedy this by hitting the switch again every few seconds until I either make the turn or come to a stop.

In the states, a timer alone wouldn't do it since we have so many stop lights with wildly varying wait times. There's one intersection on my daily commute that usually has me sitting there for up to four minutes.

This newfangled Safer Turn unit sounds interesting, but my impression is that even with a lot of smarts built in (microcontroller, accelerometers, connections to the bike's controls and engine state, etc) it's still going to get "when do I want the blinkers on or off" wrong a lot of the time. And if it did, I don't see myself paying over $100 for the convenience.

I stumbled across this guys post today and found this thread to post it on. It is way over my head, just passing info on.

That's just a pretty simple 555 timer. It'll flash the lights okay but for auto-cancelling the circuit needs to tap into the speedometer so it knows speed/distance. And for incandescent bulbs, you'd need a MOSFET or something to handle the higher current.
