ValveAutoCalibrationStatus

PVED-CL Communication Protocol, version 1.38 Technical Information
Data field (continued)
Bytes Encoding
The spool position set-point unit is a scaled value in the range -1000 to 1000, corresponding from -7 to 7 mm
nominally.
The scaled steering actuator position/steered wheel position (Yact) range is -1000 to 1000, corresponding to the
steered wheel end-lock positions. Requires that the wheel angle sensor is correctly calibrated.
The message is transmitted as a response to the StartValveAutoCalibration command. Allows monitoring
the progress and status of the valve auto-calibration.

Value/Range Description
Description
extended message identifier (XID)
Related to StartValveAutoCalibration command:
− invalid auto-calibration request
− invalid starting spool position set-point request
− invalid spool position set-point increment size request
− invalid minimum wheel angle difference threshold request
− invalid time-out period value request
Auto-calibration status/error codes:
− invalid wheel position for further auto-calibration related activities
− missing steering wheel sensor signal
− steering wheel in use
− missing steered wheel feedback sensor signal
− wheels found moving for the starting spool position set-point
– wheels not moving at maximum allowed spool position (right
direction)
– wheels not moving at maximum allowed spool position (left
direction)
– unable to update dead-band parameters
− the previously requested commit data process has not finished yet
− commit data process has failed due to the cross-parameter check
failure
− commit data process has failed due to the EEPROM write failure
− commit data process has not started on time
− commit data process has not finished on time
– unknown error (contact technical support)
− the commit data process has started
– auto-calibration in progress
− auto-calibration completed
