Problems solved by technology

However, this method does not take into account that there is no clutch in the transmission system of some hybrid loaders, and because the hybrid loader also includes an energy management system, which drives the engine to start through the power battery, it is also necessary to consider the load of the power battery. The impact of the electric state on the automatic start and stop of the engine makes it difficult for the automatic start and stop control method of the engine in the prior art to be applied to a hybrid loader without a clutch

Abstract

The invention discloses an engine automatic start-stop control method and device for a hybrid power loader. The engine automatic start-stop control method comprises the steps that whether the currentcharge state of a power battery is greater than or equal to the preset charge state or not is judged; if so, a flameout signal is sent to an engine controller when a parking signal is received; and ifany preset start condition of an automatic start-stop mode is satisfied, a start command is sent to the engine controller; and when the actual engine speed reaches the start speed which is corresponding to and meets the preset start condition, an ignition signal is sent to the engine controller. The engine automatic start-stop control method and device use the charge state of the power battery asa standard in the automatic start-stop control through determining whether the current charge state of the power battery is greater than or equal to the preset charge state or not; and through addingan accelerator pedal start condition in the preset start conditions, an accelerator pedal is used for realizing the start of an engine in the automatic start-stop function, and the applicability of the hybrid power loader is enhanced.

Description

technical field [0001] The invention relates to the technical field of loaders, in particular to an engine automatic start-stop control method and device for a hybrid loader. Background technique [0002] With the development of science and technology in modern society, people pay more and more attention to energy saving and emission reduction, which makes hybrid loaders regarded as one of the main development directions of the loader industry in the future. Among them, the automatic engine start-stop control method has attracted more and more attention because it can make full use of the advantages of the electronically controlled engine of the hybrid loader and achieve the purpose of energy saving and emission reduction in the operation process. [0003] The automatic start-stop control method of the engine in the prior art is mainly aimed at the traditional structural characteristics of the traditional loader, and detects the clutch signal, the handbrake signal, the wheel...
