DPB_a051_PSCVoltageImplausible
Description
Based on the motor current vector and speed the voltage vector is not plausible.
Condition
Based on the differential motor model equations the expected voltage vector is calculated from measured motor phase currents and motor speed. This is compared to the output of the field-oriented current controller. In case of large deviations the alert is triggered.
Clear Condition
Ignition off; wait 5 seconds; Ignition on
Potential Impact
System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.
Customer Facing Message 1
