Abstract

The invention relates to a control method and device of an engine system, a storage medium and electronic equipment, the engine system comprises a motor used for adjusting a variable compression ratio mechanism and a power supply module, the power supply module jointly provides power for the motor and other electric devices in the engine system, and the control method comprises the steps that the output voltage Ub of the power supply module is obtained; when the output voltage Ub of the power supply module is smaller than a first preset value and larger than or equal to a second preset value, the compression ratio of the engine is adjusted to be smaller than or equal to a first compression ratio by adjusting the variable compression ratio mechanism, and then the motor is controlled to be powered off; when the output voltage Ub of the power supply module is smaller than a second preset value, the motor is controlled to be powered off. Therefore, when the power supply module is abnormal, the adjusting motor of the variable compression ratio mechanism can be cut off, and the compression ratio of the engine is not adjusted any more, so that the power consumption of the power supply module is reduced. And meanwhile, the first preset value and the second preset value are adopted for hierarchical control, and knocking and engine energy consumption can be reduced.

Description

technical field [0001] The present disclosure relates to the technical field of engines, and in particular, to a control method for an engine system, a control device for an engine system, a computer-readable storage medium, and an electronic device. Background technique [0002] With the deteriorating human living environment and the continuous development of automobile energy-saving and emission reduction technologies, the fuel consumption and emission regulations of passenger vehicles are becoming more and more strict. How to improve the energy efficiency of automobile engines and improve emissions is a long-term technical problem for internal combustion engine developers. There are many parameters in an internal combustion engine that are closely related, both complementing each other and restricting each other. Among them, the proposal of variable compression ratio technology provides the possibility for the development of internal combustion engine technology. Variab...
