ISO 19206 Road Vehicles - Test Equipment for the Evaluation of Active Safety Functions for Target Vehicles, Vulnerable Road Users and Other Objects

The standard “ISO 19206 Road vehicles - Test equipment for the evaluation of active safety functions for target vehicles, vulnerable road users and other objects”, also published by the International Organization for Standardization (ISO), consists of a series of sections published under the same title. Namely,

• The standard “ISO 19206-1 Part 1: Requirements for rear impact targets of passenger vehicles” describes the performance requirements for surrogate targets used to evaluate the system detection and activation performance of active safety systems. This standard specifies the characteristics of a vehicle target that will enable it to represent a passenger vehicle in terms of size, shape, reflectance characteristics and similar aspects for test purposes. It also addresses the detection requirements for a vehicle target in terms of the detection technologies commonly used at the time of publication of this standard and, if applicable, anticipated future detection technologies. It also addresses methodologies for verifying target response characteristics to these sensors and the performance requirements for the target carrier.

This document specifies the vehicle target specifications for simulating rear-end scenarios with greater than 50 percent overlap. The vehicle target specifications in this standard are intended to address current and anticipated test protocols for safety-critical events where the subject vehicle approaches from behind and from the forward path of the subject vehicle, approaching a stopped, braking, or slower moving vehicle. This standard does not address test procedures for speeds, locations, or timing of events. Performance criteria for active safety systems are also not addressed.

For the purposes of this standard, the following definitions apply in addition to the terms and definitions given in ISO 8855:

• The subject vehicle is the vehicle with the active safety system to be tested.
• The vehicle target is a test device representing a vehicle in the forward path of the subject vehicle used to test active safety systems.
• The target structure is the physical structure used to activate sensor systems that represents the body of a vehicle.
• A target carrier is the mechanical system used to move a target structure according to a test protocol. It may be self-contained or support the target structure or external devices connected by cables, beams, or similar structures.
• Measuring equipment is equipment used to record the position and movements of the vehicle target relative to the subject vehicle to ensure that the test protocol is followed within prescribed tolerances and to record data that documents the function of the active safety system and allows its performance to be evaluated.

This standard does not address test procedures in terms of speed, location or timing of events. Performance criteria for the active safety system being evaluated are also not addressed. According to this document, a relevant test procedure using pedestrian targets is included in the standard “ISO 19237 Intelligent transportation systems - Pedestrian detection and collision mitigation systems (PDCMS) - Performance requirements and test procedures”.

For the purposes of this standard, the terms and definitions given in ISO 8855 apply. In addition, a pedestrian target is a test device representing a pedestrian used to test active safety systems.

• “ISO 19206-3 Part 3: Requirements for passenger car 3D targets” describes the performance requirements for surrogate targets used to evaluate system detection and performance of active safety systems. This standard specifies the characteristics of a versatile multi-purpose vehicle target for the evaluation of interaction in a variety of traffic scenarios. This standard specifies the characteristics of a vehicle target that will enable it to represent a passenger vehicle in terms of size, shape, reflectance characteristics and similar aspects for test purposes. It also addresses the detection requirements for a vehicle target in terms of detection technologies commonly used at the time of publication of this standard and anticipates future detection technologies where possible. It also addresses methodologies for verifying target response characteristics to these sensors and the performance requirements for the target carrier. The vehicle targets specified in this standard reflect passenger cars and in particular the smaller and more common B and C segment cars. This standard does not address test procedures in terms of speeds, locations or timing of events. Performance criteria for an active safety system are also not addressed.

For the purposes of this standard, the following definitions apply in addition to the terms and definitions given in ISO 8855:

• The target axis system, the axis system is fixed in the target reference frame so that the axis is essentially horizontal and forward (when the target is stationary) and parallel to the longitudinal plane of symmetry of the target and perpendicular to the longitudinal plane of symmetry of the target and pointing to the left when this axis points upward.
• Coordinate system based on the target axis system, the origin is located at the target reference point.
• The target reference point is the point whose position relative to the external dimensions of the target remains fixed in the initial condition.
• Lateral path deviation is the position error of the target vehicle relative to the planned path and is measured perpendicularly from the planned path direction.
