The invention provides an accelerator pedal filtering method and device. The accelerator pedal filtering method comprises the following steps that the driving demand state of a driver is determined; and under the condition that the driving demand state is a fast response demand state, signal filtering is carried out according to a preset fast response filtering parameter; under the condition thatthe driving demand state is a non-fast response demand state, a modified filtering parameter is calculated, and signal filtering is carried out according to a filtering parameter obtained by superposing the modified filtering parameter and a preset basic filtering parameter, wherein the basic filtering parameter is greater than or equal to the fast response filtering parameter. The accelerator pedal filtering method and device can realize fast response by using the smaller fast response filtering parameter under the fast response demand state. However, in the non-fast response demand state, the larger corrected filtering parameter is used for reducing instability and improving driving comfort. Based on the accelerator pedal filtering method, rapidly changing driving requirements can be applied, and engine performance can be improved.
Description
technical field [0001] The invention relates to the technical field of engine control, and more specifically, to an accelerator pedal filtering method and device. Background technique [0002] At this stage, in order to avoid signal interference, the accelerator pedal signal needs to be filtered before it can be truly used as the pedal input of the engine controller. [0003] However, the existing filtering method simply divides the opening of the accelerator pedal into multiple opening intervals, and uses different filtering parameters for signal filtering in different opening intervals. But this cannot adapt to rapidly changing driving demands and reduces engine performance. Contents of the invention [0004] In view of this, in order to solve the above problems, the present invention provides an accelerator pedal filtering method and device, the technical solution is as follows: [0005] A method for filtering an accelerator pedal, comprising: [0006] Determine the ...
