Abstract

At present, there are many types of system products with independent functions in car borne electronic products. It is not convenient to use and install such many single functional products in limited space in a car. Moreover, it is too expensive to equip these single functional electronic products completely. Thus, using multifunctional information process technique including CPU with controllable software of multiple interfaces, SRAM, DRAM, and flash memory, the invention builds up kernel process unit with multiple interfaces. Multiple connector units of possessing functions of electrical controlled information exchange are connected to the said interfaces. Each connector unit can connect electrical controlled digital devices. Advantages are: simple structure, small size, easy of installation, networked and opened structure, sufficient space for combination between software and hardware inside car so that it is convenient to upgrade to new products.

Description

technical field [0001] The invention relates to the field of signal exchange and processing of electronic control information, especially the signal exchange and processing of vehicle-mounted multifunctional information. Background technique [0002] At present, in the automotive electronic product market, there are many types of products with perfect functions.
