Abstract

The invention belongs to the technical field of engines, and provides an engine lubrication control method and a control device applied to an oil-electricity hybrid drive vehicle and the oil-electricity hybrid drive vehicle. The method comprises the steps that the engine working mode of the vehicle is obtained, and if the engine working mode is a non-running mode, the current state of the vehicleand corresponding monitoring parameters are obtained; and if the monitoring parameters corresponding to the current state of the vehicle meet the corresponding preset conditions, a corresponding firstinstruction is sent to a motor oil pump of the vehicle, and the first instruction is used for indicating the motor oil pump to extract engine oil based on the working parameters of the first instruction and convey the engine oil to a friction pair of the engine. According to the engine lubrication control method, the control device and the oil-electricity hybrid drive vehicle, the friction pair of the engine of the hybrid vehicle can be fully lubricated in time in a non-running state, and the possibility of abrasion during starting and running of the engine is reduced, so that the engine is protected.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to an engine lubrication control method, a control device, an oil-electric hybrid drive vehicle and a storage medium. Background technique [0002] At present, gasoline-electric hybrid vehicles are developing rapidly and are becoming more and more popular in the market. On the one hand, gasoline-electric hybrid vehicles have the advantages of sufficient power of the fuel power system and strong battery life. On the other hand, electric vehicles also have the advantages of reduced energy consumption and low emissions, so they are welcomed by consumers. [0003] However, during the use of the hybrid electric vehicle, the friction pair of the engine of the hybrid electric vehicle has a higher loss than that of other types of vehicles. Contents of the invention [0004] In view of this, the embodiments of the present invention provide an engine lubrication control method,...
