|
EPAS reset. If reset more than 5 times then EPAS full loss of assist.
|
|
|
This alert is reported by the DeadlineMonitor (DM) if the elapsed time between two 250us task starts is out of the tolerated range on Core 1 then Safety Reset is initiated.
|
EPAS application operating system monitor detected out of tolerated range elapsed time between two 250us task starts on Core 1.
|
EPAS reset.
|
|
|
This alert is reported by the Deadline Monitor (DM) when at least one of the monitored tasks didn't finish or finished multiple times during its configured time frame on Core 1.
|
EPAS application operating system monitor detected task timeout or task finished multiple times during its configured time frame on Core 1.
|
EPAS reset.
|
|
|
This alert is reported when there is a motor overtemperature. Degradation parameters/estimator shall be checked, if those are correct, HW failure.
|
EPAS application diagnostics detected overtemperature (motor actuator).
|
EPAS full loss of assist.
|
|
|
This alert is reported by the ExceptionHandler_TC3x (EXCH) component when there is a watchdog timeout exception.
|
EPAS application component ExceptionHandler detected exception (watchdog).
|
EPAS reset.
|
|
|
This alert is reported in case a reset is caused by exception on core1.
|
EPAS application component ExceptionHandler detected exception (core1) which causes a guarded reset.
|
EPAS reset.
|
|
|
This alert is reported by the PlatformModeProvider_R12 (PMP) component if phase current QualityofService is CS_ERROR and tolerance timeout has elapsed or the PhaseCurrents have latent failure and MotorController is not operating.

EPAS rotor speed QoS is fauly or not reliable for longer than a tolerated time.
|
EPAS full loss of assist.
|
|
|
This alert is reported by the PlatformModeProvider_R12 (PMP) component when battery or DQ current QualityofService is CS_ERROR and tolerance time has elapsed or battery or DQ QoS latent failure with MotorContoroller operation mode is MOC_INACTIVE_OP_MODE.
|
Battery or DQ current QoS is faulty and tolerance time has elapsed or battery or DQ QoS latent failure with MotorContoroller operation mode is inactive.
