AI Technical Summary

Technical Problem

In the vehicle smart cockpit, the bus signal received by the system communication controller when the system-level chip is not ready cannot be accurately transmitted, resulting in the system communication controller being unable to report the signal data to the system-level chip in time, affecting the normal operation of the vehicle smart cockpit.

Method used

When the system-level chip is not ready, the bus signal obtained by the system communication controller is processed and the signal cache data required for reporting is stored locally, and the system-level chip is reported before reporting.

Benefits of technology

Data is cached by local storage of signals, errors and loss of signal data are avoided during transmission, normal operation of the vehicle's smart cockpit is ensured, and the risk of excessive load on the serial peripheral interface between the system communication controller and the system-level chip is reduced.

Abstract

The invention provides a signal processing method and device, a storage medium, a system communication controller and a vehicle. According to the signal processing method provided by the invention, the system communication controller at a vehicle intelligent cabin can obtain first working state information of a system-on-chip at the vehicle intelligent cabin; if the system-on-chip is identified to be in a non-ready state according to the first working state information, the system communication controller can process an acquired bus signal according to a preset signal caching strategy, and locally stores signal caching data required to be reported to the system-on-chip; therefore, the signal cache data can be reported after the system-on-chip is ready, the signal data reported to the system-on-chip by the system communication controller can be prevented from being mistaken and lost, and normal operation of the intelligent cabin of the vehicle can be guaranteed.
