Abstract

The invention discloses an abnormal recovery method and device for a vehicle-mounted multimedia and wireless module management system. The wireless module management system is set on a terminal device. The method includes the following steps: acquiring the first abnormality that occurs during the start-up process of the wireless module information; identify whether the first abnormality is one of the second abnormalities in the wireless module management system; if the first abnormality is one of the second abnormalities, control the wireless module management system to perform abnormal recovery. The method can control the wireless module management system to perform abnormal recovery when the wireless module starts abnormally, thereby effectively improving user experience, satisfying user needs, and reducing user complaints.

Description

technical field [0001] The invention relates to the technical field of communication abnormal recovery, in particular to a method and device for abnormal recovery of a vehicle-mounted multimedia and wireless module management system. Background technique [0002] For the vehicle system, Bluetooth (BT for short) and Wireless Local Area Networks (WLAN for short) are two important functions. [0003] In general, the vehicle multimedia system is mostly based on the android platform, and the Bluetooth and WLAN functions are realized through the firmware in the wireless module management system (WCNSS) provided by Qualcomm. At present, the car multimedia can enable Bluetooth and WLAN functions by calling the interface provided by the Android framework. When these two functions are abnormal, the relevant technology recovers abnormally by restarting the multimedia or restarting the BT / WLAN. However, for the abnormality inside the WCNSS, it will not take effect even after the user r...
