AI Technical Summary

Technical Problem

The existing vehicle high-voltage activation state control is bound to the function execution state, which means that adding or changing functions requires modifying the control program, thus limiting the flexibility of vehicle functions.

Method used

It provides a high-voltage activation status request interface and a high-voltage power-on/off control module, decoupling the high-voltage activation status request interface from the function, and realizing independent control of the high-voltage activation status through interface input parameters, output parameters and arbitration procedures.

Benefits of technology

New and changed functions can be implemented without modifying the high-voltage activation state control program, improving the flexibility and responsiveness of vehicle functions.

Abstract

This application provides a method, system, and related equipment for controlling high-voltage activation status. The system includes a high-voltage activation status request interface and a high-voltage power-on / off control module. The high-voltage activation status request interface is used to determine the high-voltage activation request status of the entire vehicle and send the vehicle's high-voltage activation request status to the high-voltage power-on / off control module. The high-voltage power-on / off control module is used to control high-voltage components based on the vehicle's high-voltage activation request status and provide feedback on the high-voltage system status. This application's embodiment decouples the identification of the vehicle's high-voltage activation request status from the domain controller through the high-voltage activation status request interface, achieving decoupling between the high-voltage activation status request interface and the bound functions. This allows both new functions and changed existing functions to call the high-voltage activation status request interface without modifying the high-voltage activation status control program, improving the flexibility of adding new functions or changing existing functions in the vehicle.
