The invention provides an air pressure detection method, an air compressor inflating method and system and a vehicle. The air pressure detection method comprises the steps that the power supply voltage and the output voltage of an air pressure sensor are obtained; determining a first voltage threshold and a second voltage threshold based on the power supply voltage, and judging whether the output voltage is less than or equal to the first voltage threshold and whether the output voltage is greater than or equal to the second voltage threshold; when the output voltage is greater than the first voltage threshold and less than the second voltage threshold, determining an air pressure value of the to-be-tested component based on a pre-constructed air pressure conversion relation, the output voltage and the power supply voltage, and displaying the air pressure value on the instrument; when the output voltage is smaller than or equal to the first voltage threshold value or larger than or equal to the second voltage threshold value, fault reminding information is generated, and the fault reminding information and the set air pressure value are displayed on the instrument. Whether the barometric sensor breaks down or not can be determined, so that the accuracy of detecting the barometric value of the to-be-detected component through the barometric sensor and the instrument is improved.
