congenitally stupid . . . . and ignorant too! (me, that is)
Don't get me wrong... I luv my spyder, but what happened yesterday could have ended up really bad, not only for me but for the poor soul that I could have hit... not to mention my poor husband who would have watched it all. However, now that I have calmed down and put some thought into it I realize that I actually felt this starting Tuesday while I was on my way to the dealer for the second update, however it was very windy when I went that day and since it was just a brief glitch I just thought it was wind blowing me around... now I realize it was this problem just starting. This was before my second update.
..............
God has a way of looking out for us crazy people... that's why I have survived for so long LOL. This problem will be fixed and life will go on. I am just very happy no one got hurt... this time.
Pitmon, You did good! in a truly scary situation. My hat is off to you not only for your skill, but your attitude as well.
I had a very odd thing happen with my steering today as well.
............
In layman's terms, the bike's computer was reading that the steering was running off-center and was trying to correct it by pulling it to the left. The graphic was like looking at a clock. The hour hand should have been reading 12 o'clock, but it was displaying 1 o'clock.
That was reset to the 12 o'clock position, and my Spyder seems to be rolling along OK.
And thank you PhantomLady for sharing your experience and results - clear, concise and helpful ( to my understanding, at least )
I was told by a former BRP test rider that the power steering is an active part of the Stability Control System. It is designed to prevent the rider from turning the bars too sharply at higher speeds. This is to prevent the rider from possibly loosing control and flipping the vehicle from turning too much. . . . . . . .
During normal riding the operator makes many subconscience "corrections" with the bars to keep the vehicle going straight. BRP thinks that the steering is "locking" and there by hindering these small "corrections" causing the driver to force the handle bars too far in either direction and "oversteering" , resulting in a loss of control situation.
Way2Fast, I think the information you are relaying is correct, the steering is probably an integral part of the VSS. I also agree that the problems should be reported, though I would do it in this order: Dealer, BRP, NHTSA. The owner should use their own judgement as to the time interval between those 3 parties, but it should be reported, even if it is fixed after the first call.
One of my areas of technical expertise is in control systems... Following is a simple Control Systems 101 discourse so as to explain what I think may be happening here.
.................
Regardless of whether my hypothesis of cause is or is not on point, it is obvious to me that the feedback control system driving the power steering motor is, indeed, generating some very spurious control signals.
QM, an excellent hypothesis. And given some of the comments and experiences mentioned above and in other threads, besides "programming" issues, failing power steering units and/or failing sensors make this a highly variable situation as far as solutions go.
I have had some experience with programming and tuning PID controls myself, and your explanation makes very good sense.
. . . . . . .
At those times operator experience and skill must take over. I'm very glad Pitmon had that experience and skill in this situation.
Scotty, I could not agree more.
Now, here is what I have to add.
I did a stupid thing! From what I have read, I was am not alone.
After having the first update done (with my scheduled maintenance) I rode home and rode for the next few weeks as I alway had. As it became clear there were various results from the update ( no change, same but different, negative changes and positive changes ) I realized how stupid I had been since getting the update. I should have rode the Spyder like I did when I first bought it and was breaking it ( and me ) in. In effect, I had a "new" Spyder --- how it ran, how it handled, the parameters for conditions that would effect it were changed.
I have worked on integrating complex systems, including the type of automation that Quadmaniac and Scotty mentioned - like those in the Spyder. I should have known better and exercised better judgement. That was stupid on my part. Small changes can have major implications - some of them totally unintended. Even adding luggage ( additional weight ) or handlebar anti-vibration inserts, can and will change how the Spyder handles and performs - sometimes radically in specific conditions.
I do think BRP and the dealers performing the updates should have advised people to pay attention and to carefully test handling and performance in their everyday riding routines, in effect saying, "
You should treat your Spyder like you did when you first started riding - it may react differently from what you have experienced in the past. You may have to adjust or relearn some skills." These updates are being done to improve the quality of the Spyder's safety and in some cases, performance. But things can go wrong - both with the update AND with the mechanical aspects of the Spyder, which could be interdependent or coincidental.
You may feel this makes things "too uncertain" or "unreliable" and that it is not "right" or is just "too complex" and "inconvenient". Please, make your own call and do what you think is right for you. For me, I like what Pitmon and Scotty said; "
This problem will be fixed and life will go on." and "
At those times operator experience and skill must take over." So, I am going to watch it, practice, and repeat my advice from above;
"
You should treat your Spyder like you did when you first started riding - it may react differently from what you have experienced in the past. You may have to adjust or relearn some skills."
