AI Technical Summary
Technical Problem
Under the SOA architecture, vehicle software development cannot meet functional safety level requirements, affecting overall vehicle safety.
Method used
The functional safety service layer receives current scenario information of the vehicle, user requests, and requests from the main functional service layer. It determines whether the scenario is a hazardous scenario and verifies the consistency of the requests within the allowable fault time, and then passes them through to the functional abstraction service layer to achieve a safe state.
Benefits of technology
It improves vehicle safety, ensures timely response in dangerous scenarios, reduces information transmission time, and achieves a safe state and objectives.

Abstract
The application discloses a functional safety monitoring method and device of a vehicle, the vehicle, and a storage medium. The vehicle comprises a service-oriented SOA architecture, and the SOA architecture comprises a main function service layer, a functional safety service layer, and a function abstraction service layer. The application comprises the following steps: receiving current scene information, a user request, an intelligent driving request, and a main function service request of the vehicle; determining whether the current scene is a hazard scene, and determining whether the user request or the intelligent driving request is consistent with the main function service request; if the current scene is a hazard scene, and the user request or the intelligent driving request is inconsistent with the main function service request, then determining whether the user request or the intelligent driving request is consistent with the main function service request within a maximum allowed fault time; and if the user request or the intelligent driving request is consistent with the main function service request, then transmitting the main function service request to the function abstraction service layer. The application solves the problem that software developed based on the SOA architecture cannot meet functional safety level requirements, and enables the whole vehicle to reach a safe state and a safety target.
