Abstract

The invention relates to a self-adaptive correction method for an engine accelerator pedal. The self-adaptive correction method comprises the following steps that an accelerator pedal signal is acquired according to an engine controller; according to the static working state of an engine, the engine controller conducts self-adaptive correction parameter calculation and assignment on the accelerator pedal signal, and the opening degree of the accelerator pedal is corrected according to actual requirements; according to the dynamic working state of the engine, the engine controller verifies an accelerator pedal opening correction value by monitoring the running state parameters of the engine, and the accelerator pedal opening calculation accuracy and reasonability are judged; and according to the static working state of the engine and the dynamic working state of the engine, the engine controller establishes an accelerator pedal signal credibility detection and fault diagnosis mechanism to carry out fault diagnosis on the accelerator pedal signal. The self-adaptive correction method has the effect that the accelerator pedal self-adaptive control parameters are calculated according to the accelerator pedal working state and the engine working state, the accelerator pedal opening degree is corrected, and the accelerator pedal opening degree redundancy and reliability are guaranteed.

Description

technical field [0001] The invention relates to the technical field of accelerator pedal control, in particular to a method, device and system for adaptive correction of an engine accelerator pedal. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] At present, in the application process of marine electronically controlled engines, due to the performance differences of domestic and international marine accelerator pedals, when marine electronically controlled engines are equipped with marine accelerator pedals, it is very easy to have mismatching accelerator calibration parameters. At the same time, in addition to the function of the accelerator pedal, the accelerator pedal of the marine engine also integrates the control function of the marine engine, which leads to errors and zero drift in the accelerator pedal signal, and the lack of redundancy of the accelerator peda...
