Idle speed jitter control method, device, medium and device for hybrid electric vehicle

Abstract

The invention discloses an idle speed jitter control method, device, medium and device for a hybrid electric vehicle. The method comprises the steps of obtaining a first power required for charging apower battery of a target hybrid vehicle, a second power required for air conditioning consumption, a third power required for low voltage load consumption, and a fourth power required for transmission sliding wear consumption when the target hybrid vehicle is in a drive gear; judging whether the target hybrid electric vehicle is in an idle state; if yes, controlling the transmission of the targethybrid electric vehicle to neutral gear, controlling the engine of the target hybrid electric vehicle to output the first output power, so as to control with the idle speed jitter of the target hybrid electric vehicle; wherein the first output power is the sum of the first power, the second power and the third power. Obviously, this method can not only reduce the idle speed jitter of the target hybrid electric vehicle, but also improve the fuel efficiency of the engine.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to an idle vibration control method, device, medium and equipment of a hybrid electric automobile and the hybrid electric automobile. Background technique [0002] With the rapid development of the economy, hybrid electric vehicles use internal combustion engines and electric motors as hybrid power sources. Hybrid electric vehicles not only have the advantages of good fuel engine power, fast response and long working hours, but also have the advantages of no pollution and low noise by electric motors. , thus becoming a current research hotspot. In the prior art, in terms of controlling the idling jitter of the hybrid electric vehicle, the engine of the hybrid electric vehicle is basically used to control the idling jitter of the hybrid electric vehicle. In the control of the idling vibration of the hybrid electric vehicle, all the power loads will be loaded on the engine. At this ...
