Time To Collision (TTC) – means the remaining time before the VUT strikes the GVT,

assuming that the VUT and GVT would continue to travel with the speed it is travelling.

T

AEB

– means the time where the AEB system activates. Activation time is determined

by identifying the last data point where the filtered acceleration signal is below -1 m/s

2

,

and then going back to the point in time where the acceleration first crossed -0.3 m/s

T

FCW

– means the time where the audible warning of the FCW starts. The starting point

is determined by audible recognition

Vimpact – means the speed at which the VUT hits the GVT

Vrel_impact – means the relative speed at which the VUT hits the GVT by subtracting

the velocity of the GVT from Vimpact at the time of collision

2.2 Test Scenarios

Car-to-Car Rear Stationary (CCRs) – a collision in which a vehicle travels forwards

towards another stationary vehicle and the frontal structure of the vehicle strikes the

rear structure of the other.

Car-to-Car Rear Moving (CCRm) – a collision in which a vehicle travels forwards

towards another vehicle that is travelling at constant speed and the frontal structure of

the vehicle strikes the rear structure of the other.

Car-to-Car Rear Braking (CCRb) – a collision in which a vehicle travels forwards

towards another vehicle that is travelling at constant speed and then decelerates, and the

frontal structure of the vehicle strikes the rear structure of the other.

Car-to-Car Front Turn-Across-Path (CCFtap) – a collision in which a vehicle turns

across the path of an oncoming vehicle travelling at constant speed, and the frontal

structure of the vehicle strikes the front structure of the other.

Car-to-Car Crossing Straight Crossing Path (CCCscp) – a collision in which a

vehicle travels forwards along a straight path across a junction, towards a vehicle

crossing the junction on a perpendicular path. The frontal structure of the vehicle

under test strikes the side of the other vehicle.

Car-to-Car Front Head-On Straight (CCFhos) – a collision where a vehicle is

travelling along a straight path within its defined lane and strikes another vehicle

travelling in the opposite direction, which has drifted into the same lane as the original

vehicle. The frontal structure of the vehicle strikes the frontal structure of the other.

Car-to-Car Front Head-On Lane change (CCFhol) – a collision where a vehicle is

travelling along a straight path within its defined lane and strikes another vehicle

travelling in the opposite direction which has intentionally moved into the lane of the
