Print this reportAdded RMS check of ACC@IP for engaging STRONGDAMP filters on VIS guardianThough Kenta may report detailed situation, they found filters in the STRONGDAMP state cannot be engaged when ACC signals of the IP stage have large RMS: e.g. a case that VIS guardian goes to LOCK_ACQUISITION too soon after locklosses. In order to avoid this issue, a new state, "ACC_CALM_DOWN (1190)", was prepared for checking RMS of ACC signals before entering the STRONGDAMP state. Today I enabled this state only for Type-B suspension because Type-A suspensions were used for another commissioning activities. I will enable it for Type-A tomorrow or weekend.
----- Precisely, this new state is inserted between ALIGNED and OPEN_ISC states and RMS@IDAMP_{L,T,Y}_IN1 smaller than the threshold is required for going up to upper states. A escape path for going back to lower states (e.g. ALIGNED) is availalbe for a case that RMS cannot be calm down for some troubles. Threshold for this check can be set in params{A,B}.py same manner as other thresholds for ISOLATING, ALIGNING, etc.

Print this reportI applied this update for all Type-A suspensions.
Now all suspensions that have IP and IDAMP path were updated. This issue was closed.
