Ford_SYSR：FS_REQ0026_V2 DRL Control Strategy
100%
描述
The module will be capable of determining DRL state by either BCM LIN or by BCM ‘L/RF_DRL_LAMP_Ckt’ direct wire.
When direct wire control is used the parameter “DRL_POS_Trigger_DutyCycle_cfg” will trigger the DRL to go into lower intensity mode referred to position function when the direct wire duty cycle falls below the configured value. Values range between 10-41%, 200Hz.
If BCM DRL direct wire duty cycle >= “DRL_POS_TriggerDC_cfg”, it should be ‘DRL intensity’.
If BCM DRL direct wire duty cycle < “DRL_POS_TriggerDC_cfg”, it should be POS intensity, which is configured by parameter ‘ParkPos_Intensity_cfg’.
NOTE1: Set ‘DRL_POS_Trigger_DutyCycle_cfg’ significantly higher/lower than BCM DRL direct wire duty cycle value to avoid the sampling error. For example: If BCM DRL direct wire duty cycle of POS is 10%, ‘DRL_POS_Trigger_DutyCycle_cfg’ should be at least 15%.
NOTE2: POS duty cycle cannot be below 5%. Lower values will be ignored and 5% will be used instead.
NOTE3: “DRL_Intensity” should be 100% as default value.
