Abstract

The invention discloses an upgrading method for a motormeter software. The upgrading method comprises the steps that a central control end acquires a motormeter upgrading package from an external memory device or an Internet, the motormeter end judges validity of a received motormeter upgrading package through length and ciphertext detection, and an upgrading zone bit value is set corresponding toa host processor and/or a co-processor in the motormeter upgrading package. The upgrading method achieves that the motormeter upgrade are independent of professional equipment and staffs, and a USB flash disk, a telephone and other external storage devices or the Internet can be used to upgrade the motormeter, thereby greatly improving the upgrading efficiency of the motormeter and reducing the upgrading requirements of the motormeter. The upgrading method has the advantages that the validity of the motormeter end acquiring the upgrading package is ensured, it is avoided that a failed upgradecaused by a transmission error leads to operation troubles of a motormeter end software, and the safety, reliability and stability of the software upgrading are improved.

Description

technical field [0001] The invention relates to a method for upgrading instrument software, in particular to a method and system for upgrading automobile instrument software. Background technique [0002] The instrument terminal is composed of various instruments, indicators, and driver warning lights and alarms, etc., providing the driver with information on vehicle operating parameters. Automobile instruments can be roughly divided into three generations according to the working principle. The first generation of instrumentation is a mechanical movement table; the second generation of automobile instruments is called electrical instrumentation; The instrument has more powerful functions, richer display content, and simpler wiring harness links. [0003] The full liquid crystal instrument in the third-generation all-digital automotive instrument has a rich and vivid instrument interface, diversified display content, and a high frequency of software upgrades. At present, i...
