Embodiment Construction

[0045] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0046] Such as Figure 1 ~ Figure 3 Shown, the self-learning correction method of a kind of automobile pedal travel signal of the present invention is characterized in that, the method comprises the following steps:

[0047] S01, read the highest value of the reference signal, the lowest value of the reference signal, the high stroke correction value and the low stroke correction value;

[0048] Specifically, read the highest value of the reference signal, the lowest value of the reference signal, the high stroke correction value and the low stroke correction value are voltage values, wherein the maximum value of the reference signal is less than the maximum value o...

Abstract

The invention relates to the technical field of automobile signal correction, in particular to a self-learning correction method and system for automobile pedal travel signals. Comprising the following steps: S01, reading a reference signal maximum value, a reference signal minimum value, a high stroke correction value and a low stroke correction value; s02, reading a pedal travel signal, and judging whether the pedal fails or not; s03, when the pedal breaks down, a fault signal is output; s04, when the pedal does not break down, the range of the pedal travel signal is adjusted; s05, the pedal travel signal is converted into a temporary variable, and whether the numerical value is reasonable or not is judged; s06, when the numerical value is unreasonable, outputting a correct pedal percentage signal and returning to the step S05; s07, when the numerical value is reasonable, judging whether the maximum value of the reference signal is normal or not; s08, if not, correcting the maximum value of the reference signal and returning to the step S05; and S09, if the temporary variable is normal, converting the temporary variable into a pedal percentage signal and outputting the pedal percentage signal. The method has the advantages of simplicity, convenience, feasibility, complete functions and reduced implementation cost.

Description

technical field [0001] The invention relates to the technical field of automobile signal correction, in particular to a self-learning correction method and system for automobile pedal stroke signals. Background technique [0002] The car pedal is an important control part on the car, usually including the accelerator pedal, the brake pedal and the clutch pedal, through which the driver controls the car. There is a stroke sensor on the pedal of the car, which can convert the stroke of the pedal into a voltage signal, and the central control of the car can read the signal to issue a work command. However, it is difficult to ensure the consistency of the stroke sensor when it leaves the factory, and there are certain errors in itself. In the subsequent automobile production and assembly process, the car pedal is affected by the installation accuracy, and its initial position is also offset; in addition, the car pedal After long-term use, the movement of the pedal will produc...
