ISO 13185-2:2015规定了ASN的要求。车辆及其站点网关（V-ITS-SG）和游牧和/或移动设备（ND）之间基于1的协议，用于轻松交换车辆信息数据。 ASN。已指定基于1的协议来支持ND和V-ITS-SG之间的有线或无线连接。 V-ITS-SG和ND之间使用统一网关协议（UGP）。UGP支持多种功能，以提供 ·授权（数据隐私）， ·安全访问， ·V-ITS-SG和车内ECU识别， ·ASN中带有标识符和类型信息的实时车辆数据参数。1.格式，以及 ·ASN中带有标识符和类型信息的增强型车辆数据参数。 1.格式。

ISO 13185-2:2015 specifies the requirements of an ASN.1-based protocol between a vehicle-ITS-Station Gateway (V-ITS-SG) and a nomadic and/or mobile device (ND) to easily exchange vehicle information data. The ASN.1-based protocol has been specified to support a wired or wireless connection between the ND and V-ITS-SG. The Unified Gateway Protocol (UGP) is used between the V-ITS-SG and the ND. UGP supports several features in order to provide · authorization (data privacy), · secured access, · V-ITS-SG and in-vehicle ECUs identification, · real-time vehicle data parameters with identifier and type information in ASN.1 format, and · enhanced vehicle data parameters with identifier and type information in ASN.1 format.
