Part 3: Requirements for passenger vehicle 3D targets

1 Scope

This document specifies performance requirements for surrogate targets used to assess the system detection and performance of active safety systems.

This document specifies the properties of an omni-directional multi-purpose vehicle target for assessment of interaction in a variety of traffic scenarios.

This document specifies the properties of a vehicle target that will allow it to represent a passenger vehicle in terms of size, shape, reflection properties, etc. for testing purposes. This document addresses the detection requirements for a vehicle target in terms of sensing technologies commonly in use at the time of publication of this document, and where possible, anticipates future sensing technologies. It also addresses methodologies to verify the target response properties to these sensors, as well as performance requirements for the target carrier.

The vehicle targets specified in this document reflect passenger cars and, in particular, the smaller and more common B and C segment cars.

This document does not address the test procedures in terms of speeds, positions, or timing of events. Performance criteria for the active safety system are also not addressed.

3.1

subject vehicle

SV

vehicle with active safety system to be tested

ISO 19206-3:2021

3.2

vehicle target

VT

test device representing a vehicle, whose purpose is to activate sensor systems

Note 1 to entry: Vehicle target consists of a target structure (3.2.1) and optionally a target carrier (3.2.2).

Note 2 to entry: This document addresses test devices representing a vehicle having the necessary features to be recognised from any direction (3D vehicle target).

3.2.1

target structure

physical structure whose purpose is to maintain the shape and provide the relevant sensor signature representing a vehicle

3.2.2

target carrier

mechanical or electro‑ mechanical system used to move and/or support the target structure (3.2.1) according to a test protocol

Note 1 to entry: Target carrier may be self‑ contained within, or supporting the target structure or external devices connected with cables, beams, or similar structures. It can also be a self‑ propelled carrier.

Note 2 to entry: Target structure and target carrier may be integrated.

Note 3 to entry: Target structure fixation is included in the target carrier.

3.3

target axis system

axis system fixed in the reference frame of the target, so that the X axis is substantially horizontal and t

forward (with the target at rest), and is parallel to the target’s longitudinal plane of symmetry, and the Y axis is perpendicular to the target's longitudinal plane of symmetry and points to the left with the Z t t

axis pointing upward

Note 1 to entry: See Figure 2 for further explanation of the target axes X , Y , Z .

t t t

3.4

target coordinate system

coordinate system based on the target axis system (3.3) with the origin located at the target reference point (3.5)

Note 1 to entry: The position of the vehicle in the target coordinate system is described by coordinates x , y , z .

t t t

3.5

target reference point

point whose location relative to the external dimensions of the target, in its initial condition, remains constant

Note 1 to entry: to entry:

x = 0, y = 0 at the centroid of the area defined by a horizontal projection of the plan view of the target;

z = 0 at the ground plane.

3.6

measurement equipment

equipment used to record the position and motions of the vehicle target (3.2) relative to the subject vehicle (3.1)

Note 1 to entry: The measurement equipment is used to ensure that the test protocol is followed within prescribed tolerances and to record data documenting the function of the active safety system and allowing its performance to be assessed.
