BS ISO 20530-1 This document defines the use cases and general requirements for supporting emergency services via P-ITS-S. Any automotive-related service providers can refer to this document for developing eCall service systems into eCall non-supportive vehicles.The P-ITS-S acts as a monitoring and data transmitting device which gathers a vehicle’s speed, impact
and airbag deployment signal to assess the accident occurrence and type of accident. Once gathered data has been determined as an accident, accident related information is sent to an emergency service centre.Only notable events, such as an airbag-deployed event, rollover and stationary accident, are concerned by this document. In addition, the vehicle data gathering device requirement and implementation methodology for the emergency service are not applicable to this document. 2，Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.ISO 13185-2, Intelligent transport systems 一Vehicle interface for provisioning and support of ITS services一Part 2: Unified gateway protocol (UGP) requirements and specification for vehicle ITS station gateway (V-ITS-SG) interface ISO 13185-3, Intelligent transport systems一Vehicle interface for provisioning and support of ITS Services一Part 3: Unified vehicle interface protocol (UVIP) server and client API specification ISO 2121Z Intelligent transport systems一Communications access for land mobiles (CALM)一Architecture.The accident detection system consists of the UVIP server, which is a part of an in-vehicle system and a P-ITS-S. The role of a P-ITS-S is to gather accident data from the UVIP server, to analyse this data, and send the location of the accident detected to the emergency service centre.The accident detection system implementation method differs according to G-sensor availability within a vehicle. Whether there is an in-vehicle or P-ITS-S G-sensor, impact data is gathered and sent to the P-ITS-S for the further accident determination process.The accident determination process differs according to the accident case (e.g. airbag deployed, rollover and stationary) as well as the required data. Required data is covered in use case cluster 2. Figure 1 shows the accident detection reference system.BS ISO 20530-1 pdf download.
