[0002] Automobile is a power-driven, non-track-borne vehicle with 4 or more wheels, mainly used for: carrying people and (or) goods; towing vehicles carrying people and (or) goods; special purposes, and automobile controller is one of the parts of automobile, and automobile controller is a type of controller.
[0003] A controller is a main command device that changes the wiring of the main circuit or control circuit and the resistance value in the circuit in a predetermined order to control the start, speed regulation, braking and reversal of the motor. It is composed of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. It is the "decision-making body" that issues commands, that is, it completes the coordination and command of the operation of the entire computer system. The controller is divided into a combinational logic controller and a microprogram controller. The two controllers have their own strengths and weaknesses. The combinational logic controller is difficult to design and has a complex structure. Once the design is completed, it cannot be modified or expanded, but it is fast. The microprogram controller is easy to design, simple in structure, and easy to modify or expand. To modify the function of a machine instruction, you only need to recompile the corresponding microprogram; to add a machine instruction, you only need to add a microprogram in the control memory, but it is executed by executing a microprogram. The specific comparison is as follows: The combinational logic controller is also called a hard-wired controller. It is composed of logic circuits and relies entirely on hardware to realize the function of the instruction.
