485. BSM motorcycle overtaking

The EMT (Euro NCAP Motorcyclist Target) approaches the VUT (Vehicle Under Test) from behind, comes into the Blind Spot Monitoring (BSM) zone and then overtakes the VUT.


Map requirements: A road with at least two lanes in the same direction

Actors:

  • VUT : The ego vehicle is called VUT

  • EMT : The vehicle which overtakes the VUT


Maneuver description

In this scenario, the VUT drives on a road with the EMT in the adjacent lane with lateral distance of 1.5m from the lane marking, and approach the VUT from behind on the right or left.

485.1 Phase description

Initial drive: init_drive - The EMT and VUT both have initial drive of 2 to 5 seconds

Overtake drive: overtake_drive - The EMT starts with the distance of min_lon_distance and max_lon_distance of BSM zone from VUT. The VUT speed and EMT speed are constant throughout scenario. When the VUT triggers the left or right turn signal, the EMT present in the BSM zone is detected and BSM is engaged. At the end of the scenario, the EMT overtakes the VUT.The duration of the scenario is 5 to 9 seconds with tolerance of 2seconds.


485.2 FRun parameters

Configuration Type Range Description
turn_signal_state turn_signal_state [left_on,right_on] Turn indicator signal side
min_lon_distance length 2m Minimum distance from VUT for Blind Spot Monitoring Zone
max_lon_distance length 10m Maximum distance from VUT for Blind Spot Monitoring Zone


485.3 Events

  • vut_rel_distance_to_emt_event: The event is triggered until the emt is behind the vut and the event is off when the emt is ahead of the vut.

485.6 Checks

The check will fail if any of the following happen:

  • BSM is not in the active state during the scenario
  • BSM Alert did not trigger when the EMT was in the BSM zone
  • BSM alert triggered when the EMT was not inside the BSM zone
