| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
rotor position sensor raw signals: vector length is oscillating.
|
Magnetic field distorted or electrical alert of rotor position sensor raw signals. Oscillations or jumps detected.
|
System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.
|
|
|
The alert is logged whenver the absolute deviation between the unfiltered RPS speed and filtered speed exceeds 711.2 rad/s, provided the actuator position is valid.
|
Implausible too high angle jump in RPS signal, alert is logged if an implausible high angle jump in the rotor position signal is detected while the actuator position is valid.
|
System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.
