Abstract

The invention provides a software refresh control method and device and Internet of Vehicles equipment, which are applied to the technical field of automobiles. According to the invention, after a refresh instruction is obtained, the current SOC values of a target data packet and a storage battery are obtained, when target software corresponding to the target data packet is calculated and refreshed according to the target data packet, according to the electric quantity threshold of the storage battery, the size relationship between the current SOC value of the storage battery and the electricquantity threshold of the storage battery is compared, and if the current SOC value is not smaller than the electric quantity threshold of the storage battery, the target software is refreshed. According to the software refresh control method and device and the Internet of Vehicles equipment provided by the invention, the electric quantity of the storage battery is assessed before each piece of software is refreshed, and the target software is refreshed on the premise that the current SOC value of the storage battery is not smaller than the electric quantity threshold of the storage battery, so that deep discharge of the storage battery caused by software upgrading is avoided, and the normal service life of the storage battery is ensured.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a software refresh control method, device and Internet of Vehicles equipment. Background technique [0002] FOTA (Firmware Over-The-Air, software upgrade over the air) refers to providing software upgrade services for devices with Internet-connected functions through cloud upgrade technology to complete system repair and optimization. For in-vehicle electronic equipment, such as T-BOX (Telematics Box, Internet of Vehicles equipment), in-vehicle infotainment system, or other ECU (Electronic Control Unit, Electronic Control Unit) that needs to be upgraded, it is also possible to use FOTA technology to implement software after networking. Refresh upgrade. [0003] In the prior art, when the vehicle uses FOTA technology for software refresh, the control network of the whole vehicle is in the wake-up state, and the storage battery supplies power for each vehicle elect...
