ISO/SAE 21434 defines cybersecurity risk management across the lifecycle of road-vehicle electrical and electronic systems. It matters to V2X because it gives independently developed systems a common technical contract.

Defines message sets and data elements used for dedicated short-range and connected-vehicle communications, including safety and mobility messages.

SAE J2847/1 defines messages used between plug-in vehicles and the grid for managed charging use cases. It matters to V2X because it gives independently developed systems a common technical contract.

SAE J2847/2 defines digital communication between a vehicle and an off-board direct-current charger. It matters to V2X because it gives independently developed systems a common technical contract.

SAE J2847/3 defines communications for a plug-in vehicle participating as a distributed energy resource. It matters to V2X because it gives independently developed systems a common technical contract.

SAE J2931/1 defines general digital communication requirements between plug-in vehicles and charging infrastructure. It matters to V2X because it gives independently developed systems a common technical contract.

SAE J2931/4 defines broadband power-line communication used for high-level vehicle-to-charger messaging. It matters to V2X because it gives independently developed systems a common technical contract.

SAE J2945/1 defines minimum performance and behavior for on-board V2V safety communication using SAE J2735 messages. It matters to V2X because it gives independently developed systems a common technical contract.

SAE J2953/1 defines interoperability and performance tests for vehicles, charging equipment, and their communication interfaces. It matters to V2X because it gives independently developed systems a common technical contract.

SAE J3161/1 defines minimum LTE-V2X on-board performance for V2V safety applications. It matters to V2X because it gives independently developed systems a common technical contract.

SAE J3216 defines a vocabulary and classes for cooperative driving automation that distinguish coordination among road users and infrastructure. It matters to V2X because it gives independently developed systems a common technical contract.

A SAE J2735 vehicle message carrying frequently updated motion and status data for safety applications.

A V2X message encoding intersection lanes, approaches, connections, and reference geometry.

A V2X-specific credential architecture for trustworthy, privacy-preserving message authentication.

A V2X message describing current signal indications and expected timing at a controlled intersection.
