This document specifies a method to evaluate the behaviour of a vehicle equipped with an autonomous emergency braking system (AEBS), or dynamic brake support (DBS) during several accidents scenarios, which occur during a straight line driving when the vehicle under test approaches another vehicle in the same lane, where the longitudinal axis of the two vehicles are almost the same.

The most important part of the vehicle behaviour during these accidents scenarios is the capacity to avoid or mitigate the collision.

A system requiring a driver intervention is not in scope of this document.

NOTE Depending on accidentology, only a part of the scenarios can be used for an evaluation of performance.

This document establishes a standard for the classification and application of modular simulation models with regard to vehicle dynamics in context of global vehicle without human driver. With the created framework a systematics was created, defining how the requirements of simulation models can be defined for certain application and driving manoeuvres. Thus, allowing to specify the requirements for simulation models for necessary applications and driving manoeuvres in a standardized way.


For this purpose, the proposed framework systematically divides the vehicle model into model classes and all model classes into different model types, corresponding to different model characteristics and common modelling methods. The vehicle dynamics manoeuvres were additionally structured and clustered. One can assign the manoeuvers to the model classes and model types using an allocation and requirement table. The standard thus also creates the basis for model recommendations relevant to vehicle dynamics with regard to Advanced Driver Assistance Systems and Automated Driving (ADAS/AD).


The application of the framework and the specification of the model requirements are the responsibility of the user or may be determined by other regulations and standards. The standard contains recommendations for selectable model characteristics in terms of adequate simulation quality with respect to performance tests and associated application patterns. With regard to functional testing, the recommendations can be adapted accordingly.

This document specifies a chassis dynamometer test procedure to determine the end of CD (charge-depleting) state and consumed electric energy during CD state.

The identification of the end of CD state is an important step for procedures to determine exhaust emissions and fuel consumption. Final determination of exhaust emissions and fuel consumption is not included in this document.

This document applies to vehicles with the following characteristics.

— The vehicles are hybrid-electric road vehicles (HEV) with an internal combustion engine (ICE) and an on-board rechargeable energy storage system (RESS) for vehicle propulsion which is supplied with electric energy from an external electric power source.

— A CD state, in which the electric energy in the RESS from an external electric power source is consumed, is followed by a CS (charge-sustaining) state in which the fuel energy is consumed sustaining the electric energy of the RESS.

— Only batteries are assumed as the RESS of a vehicle.

— The RESS is not charged while driving unless by regenerative braking and/or by generative operation driven via the ICE.

— External charge for the purpose of conditioning of the RESS is not included.

NOTE 1 Trolleybuses and solar powered vehicles are not included in the scope.

— The vehicle is classified as a passenger car or light duty truck, as defined in the relevant regional ADT standard.

— For the ICE, only liquid fuels (for example, gasoline and diesel fuel) are used.

NOTE 2 In the case of vehicles with ICE using other fuel [for example, compressed natural gas (CNG), hydrogen (H2)], this document can apply except the measurement of consumed fuel; otherwise the measurement method for those using the corresponding fuel can apply.

This document gives minimum safety, ergonomic, and performance requirements for Camera Monitor Systems to replace mandatory inside and outside rearview mirrors for road vehicles (e.g. classes I to IV as defined in UN Regulation No. 46). It addresses Camera Monitor Systems (CMS) that will be used in road vehicles to present the required outside information of a specific field of view inside the vehicle. These specifications are intended to be independent of different camera and display technologies unless otherwise stated explicitly. Advanced driver assistance systems (ADAS), such as parking aids, are not part of this document.

NOTE 1 Mirror classes V and VI (as defined in UN Regulation No. 46) are not in scope of this document since the requirements are already defined in UN Regulation No. 46.

NOTE 2 The definitions and requirements in this document are formulated with regard to a system structure, where one camera captures one legally prescribed field of view and one monitor displays one legally prescribed field of view. Of course, also other system structures (e.g. with one monitor displaying two legally prescribed fields of view) are within the scope of this document. For those systems, either the system supplier or the vehicle manufacturer has to prove that the resulting system fulfils the requirements given in Clause 6.

NOTE 3 Whenever the phrases "field of view" or "field of vision" are used, then both have the same meaning and are to be used in parallel.

This document specifies requirements for Automotive Ethernet Switch Semiconductors to define a minimum requirement set for such devices. This should give guidance to semiconductor vendors on designing suitable devices. This document does not aim to replace existing standard documents like the IEEE 802.1D Standard (IEEE Computer Society, 2004). It rather focuses on which features of existing standards are required and in what quantity.

This document covers requirements of different categories of requirements of Automotive Ethernet switches:

— General requirements (see 5.1)

— Address resolution (see 5.2)

— Virtual LANs (see 5.3)

— Quality of service and audio/video bridging (see 5.4)

— Time synchronisation (see 5.5)

— Filtering of incoming frames (see 5.6)

— Diagnostics (see 5.7)

— Interfaces (see 5.8)

— Configuration (see 5.9)

This document defines conformance for Automotive Ethernet Switch Semiconductors.

This document specifies requirements for Controller Area Networks (CAN) between the in-vehicle network and the diagnostic link connector of the vehicle. The network presumes the use of an external test equipment for inspection and repair diagnostics, and other possible use cases. This document does not specify any requirements related to the in-vehicle CAN network architecture. This document defines the requirements to enable the in-vehicle CAN network to successfully establish, maintain, and terminate communication with the devices externally connected to the diagnostic link connector.

This document places restrictions on those International Standards for the fulfilment of the regulations. It does not specify in-vehicle CAN bus architecture, but seeks to ensure that the vehicle's regulated CAN communications comply with external test equipment requirements.

This document is the entry point for DoCAN (Diagnostic communication over Controller Area Network). Based on the results of the initialisation, the external test equipment determines which protocol and diagnostic services are supported by the vehicle’s emissions-related system.

A human-shaped thermal manikin was designed to conduct assessments of the thermal environment from an ergonomic viewpoint. ISO 14505 part 2 defines the index of the environment, also referred to as the equivalent temperature, measured by such a manikin. Part 4 provides guidelines for extending this definition to predictive purposes and specifies a standard prediction method for the assessment of thermal comfort in vehicles using numerical calculations. Specifically, the following section sets forth a simulated numerical manikin as a viable alternative to the thermal manikin for the purpose of calculating the equivalent temperature.

This portion of ISO 14505 was written with the supposition this standard will be applied to various situations such as the following:

— in the case of experimental facilities that are not prepared,

— in the case of prototypes that are incomplete,

— in the case of conditions that are difficult to simulate in controlled experimental settings,

— in the case that occupants are extrapolated to unknown or virtual Environments.
