FORD LDM Localization

High beam (of any type) shall only activate if IGN is in Run or Start.

The high beam function shall be capable of being activated/deactivated in steady state between 0% and 100% using an output PWM at 200 Hz capable of 100 light level steps. The LDM shall activate all channels assigned to HB up to 100% when the ‘High_Beam_Status’ transitions from ‘0’ to ‘1’ within the time provided by ‘LDM_HB_RampingSpeed’ in both BCM_E_FC1 and BCM_E_FC2 EEL LIN command frames. This signal will command the LDM to fade at an Immediate (within latency requirement), Fast, Medium, or Slow speed, which are configured by the parameters ‘HB_fade_fast_spd_cfg’, ‘HB_fade_med_spd_cfg’, and ‘HB_fade_slow_spd_cfg’, respectively. In each, the fade is a set length of time set by parameter.

The list of fade times is below:

0x00= 100mS fading time
0x01= 200mS fading time
0x02= 300mS fading time
0x03= 400mS fading time
0x04= 500mS fading time
0x05= 600mS fading time
0x06= 800mS fading time
0x07= 1000mS fading time
0x08= 1250mS fading time
0x09= 1500mS fading time
0x0A= 1750 mS fading time
0x0B= 2000mS fading time
0x0C= 2500mS fading time
0x0D= 3000mS fading time
0x0E= 3500mS fading time
0x0F= 4000mS fading time
