Abstract

The present invention is applicable to the technical field of automotive electronics, and provided thereby are a data refreshing method and device, as well as a computer-readable storage medium, the method comprising: acquiring a communication protocol corresponding to the vehicle type of a current user vehicle (S101); analyzing the communication protocol, and acquiring communication-related parameters (S102); generating an optimal parameter set which matches the current user vehicle (S103); and refreshing an engine control unit (ECU) data file of the user vehicle according to the optimal parameter set (S104). It is possible to guarantee that data parameters in a communication process are well maintained by means of an optimal parameter set, thus improving the success rate of refreshing and achieving faster and better refreshing.

Description

technical field [0001] The invention belongs to the technical field of automotive electronics, and in particular relates to a data refreshing method, device and computer-readable storage medium. Background technique [0002] With the improvement of living standards, cars have become a necessity in people's lives, and the requirements for car performance are also increasing. ECU upgrades can improve the performance of car systems, such as improving car power, reducing fuel consumption, and reducing exhaust emissions. [0003] However, in the process of flashing the ECU, how to improve the success rate of ECU flashing is very critical, because once the flashing fails, the vehicle is locked or has no data at this time. Only after-sales service agencies can make the vehicle work again, the operation is cumbersome, wasting a lot of time and money, and if the refresh rate is usually low through some terminal devices, how to improve the success rate of ECU flashing is an urgent pro...
