The invention discloses a method and device for controlling an engine. The method includes the automatic engine revolution speed control process. In the automatic engine revolution speed control process, real-time parameters containing the current engine revolution speed, the current needed torque and the preset minimal vehicle speed are acquired; the corresponding relation between the fuel oil consumption rate and the engine revolution speed under the current needed torque is acquired; on the premise of the corresponding engine revolution speed not smaller than the preset minimal vehicle speed, the current optimal engine revolution speed with the optimal fuel oil consumption rate is acquired according to the corresponding relationship; the engine revolution speed of the engine is updated according to the current optimal engine revolution speed. The current engine revolution speed and the current needed torque are acquired, according to the corresponding relation between the fuel oil consumption rate and the engine revolution speed under the current needed torque, the vehicle speed of a vehicle is controlled to the degree that oil consumption is the lowest on the premise that the vehicle is kept in the preset minimal vehicle speed, and then the oil consumption is further optimized.
Description
technical field [0001] The invention relates to the field of mechanical control, in particular to an engine control method and device. Background technique [0002] ECU (Electronic Control Unit, electronic control unit), as an electronic control system of a special microcomputer controller for automobiles, can calculate, process and judge according to the signals input by each sensor, and then output instructions to control the actuators to perform corresponding actions, thereby realizing such as Fuel injection control (EFI), ignition control (ESA), idle speed control (ISC) or emission control, etc. [0003] The inventor has found through research that although the ECU technology in the prior art can realize various controls including the engine speed, there is no effective technical solution on how to further optimize the fuel consumption through the ECU technology. Contents of the invention [0004] The technical problem to be solved by the present invention is to provi...
