Abstract

The embodiment of the invention provides an encoding and decoding method and device for a symmetrically distributed segment code screen. The method comprises the following steps: mapping all characteristics of all symmetrically distributed segment code screens to a single segment code screen in a non-repeated manner by adopting a method of mapping a single segment code screen by the symmetricallydistributed segment code screens; performing double / single matrix coding on the mapped single segment code screen to determine the number of pins, pin driving logic and double / single matrixes, and further decoding the corresponding double matrixes or single matrixes through a decoding circuit. The method has the characteristics of good applicability and strong practical guiding significance, and has wide popularization and application values for automobile electronic products (such as an automobile combination instrument and a central control display system) applying the segment code screen inthe engineering practice aspects of reducing the mold opening number, the cost and the maintenance and management workload of the segment code screen, enhancing the flexibility of system applicationand maintenance and the like.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automotive electronic control, and in particular to a coding and decoding method and device for symmetrically distributed segment code screens. Background technique [0002] As automobile consumption becomes more and more popular, consumer groups are gradually becoming younger, and young automobile consumers have higher and higher requirements for the comfort and entertainment of automobiles. It is widely used in automobiles, and its quantity is often one piece or multiple pieces arranged in pairs. At the same time, with the increasingly fierce competition in the automobile market, the development cycle of new models and the "price war" force manufacturers of automotive electronic components such as instrument clusters and central control systems to have shorter development cycles and lower costs. How to respond to the above-mentioned market-oriented demand for the widely used segme...
