Please see 'Verify Throttle Adjustments' in section 3.7 of the Guide.ColinB wrote:...the auto cruise still does not work. It will catch, but comes out of cruise mode after 3-4 seconds. Any suggestions on where to look?
Some 'hunting' at certain speed is not unusual, but in my experience it generally occurs under a light load (e.g. climbing a small incline) under partial throttle but this is very dependent on the controller/motor and vehicle weight. It's a little odd that you are noticing so much - particularly on the flat. Are there other limit flags in play besides 'W'? Have you tried increasing the both up and down ramping a bit?ColinB wrote:I'm using the throttle in the Power mode (so throttle is percentage of max power.) I've been tuning it with the gain settings, but can't get it perfectly smooth. How smooth should I expect it to get? It is roughest when the motor isn't having to work hard to maintain speed, say at half throttle on level ground. (Not super rough, but can still hear and feel it pulsing.) Adding throttle to accelerate is smooth.
Also - if your controller has a built-in throttle delay then the CA throttle corrections will be delayed and roughness will result as the CA continually overshoots because its actions appear to have no immediate effect and it adjusts still further to urge the controller on. What motor/controller do you have?
