Description

technical field [0001] The invention relates to an electronic control unit of an automobile engine, in particular to a 32-bit electronic control unit of a four-cylinder gasoline engine. Background technique [0002] Most of the main control chips of the current four-cylinder gasoline engine electronic control unit are 16-bit microcomputers, and the electronic control unit contains many analog circuit modules. With the increase of functions and performance of automobiles, strict requirements are put forward for electronic control units: more control objects require high control precision; control algorithms become more complex, requiring high-speed computing and processing capabilities and large-capacity storage space. The 16-bit microcomputer has been difficult to meet the needs of multitasking and processing complex algorithms, and the analog circuit is easily disturbed, resulting in poor system stability. Contents of the invention [0003] The purpose of the present inv...
