3.6 STATE TRANSITION REQUIREMENTS DESCRIPTION
3.6.1 Steering wheel related conditions
•
STW_ON (Steering wheel in use):
The PVED-CLS detects the steering wheel to be in use when,
1. |Steering wheel velocity| > threshold value for P3583 (STW in use - Velocity threshold)
AND
| Steering wheel position difference | > threshold value for P3584 (STW in use - Angle
threshold), where;
Where,
| Steering wheel position difference | = Current steering wheel position - Last detected
steering wheel position at 0 RPM
2. OR
|Internal monitoring disengage | = Active
•
STW_OFF (Steering wheel is not in use):
The PVED-CLS detects the steering wheel is not to be in use when,
|Steering wheel velocity|
≤ threshold value for P3583 (Steering wheel Velocity threshold)
Or
|Internal disengage monitoring| = Inactive
3.6.2 Auxiliary steering device (AUX) related conditions
•
AUX_OL_ON (AUX open loop device in use):
The PVED-CLS detects the AUX open loop device to be in use when,
The AUX steering device is present in the system – P3239 set to 255
AND
The AUX steering device is enabled – see flags in the MMI messages in PVED-CLS communication
protocol,
AND
1.
The AUX steering device is a mini-steering wheel – P3240 set to 2
AND
|AUX mini-steering wheel velocity| > threshold value for P3646 (AUX mini-steering in use
– Velocity threshold)
AND
| Mini-steering wheel position difference | > threshold value for P3719 (AUX mini-steering
in use – Angle threshold), where;
| Mini-steering wheel position difference | = Current mini-steering wheel position - Last
detected mini-steering wheel position at 0 RPM (i.e. Last mini-steering wheel position
when mini-steering wheel speed was below P3646)
OR
