7. DSRC OBU - Safety Applications
The DSRC OBU supports the below Safety Applications as per standard SAE J2945.
7.1 Emergency Electronic Brake Lights (EEBL)
The EEBL safety application warns the driver of the Host Vehicle (HV) in case of a
hard-braking event by a Remote Vehicle (RV) that is ahead and in the same lane or
an adjacent lane. The remote vehicle (RV) broadcasts a hard-braking event in the
BSM upon a hard braking maneuver. Upon receiving such event information, the HV
determines the relevance of the event to its own travel path and provides a warning
to the driver, if appropriate.
Figure 19. EEBL Use Case #1
EEBL Use Case 1: When remote vehicle abruptly brakes hard, then the host vehicle
receive a warning from the EEBL feature.
7.2 Forward Collision Warning (FCW)
The FCW safety application warns the driver of the host vehicle (HV) in the case of an
impending rear-end crash with a remote vehicle (RV) directly ahead in the same lane
and direction of travel. The FCW is intended to help drivers avoid or mitigate rear-end
vehicle crashes in the forward path of travel.
