Is Automotive EMS the Same as ECU?
1 Answers
Automotive EMS is not ECU. Automotive EMS is the Engine Management System, while ECU is the Engine Control Unit. The former is a system, and the latter is a physical entity. Introduction to Automotive EMS: EMS is the Engine Management System, also known as the engine computer. Its principle involves converting physical information such as the amount of air inhaled by the engine, the temperature of the coolant, engine speed, and acceleration/deceleration into electrical signals through various sensors and their circuits, which are then sent to the vehicle's controller. Introduction to Automotive ECU: ECU is the Electronic Control Unit, also referred to as the "vehicle computer" or "on-board computer." In terms of its purpose, it is a specialized microcomputer controller for automobiles. Like a regular computer, it consists of a microprocessor, memory, input/output interfaces, analog-to-digital converters, as well as shaping and driving large-scale integrated circuits.
