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.

    本发明提供了一种气压检测方法、空压机打气方法、系统及车辆,其气压检测方法包括:获取气压传感器的供电电压和输出电压;基于供电电压确定第一电压阈值和第二电压阈值,判断输出电压是否小于或等于第一电压阈值,以及输出电压是否大于或等于第二电压阈值;当输出电压大于第一电压阈值且小于第二电压阈值时,基于预先构建的气压转换关系、输出电压和供电电压确定待测部件的气压值,并将气压值显示于仪表;当输出电压小于或等于第一电压阈值或输出电压大于或等于第二电压阈值时,生成故障提醒信息,并将故障提醒信息和设定气压值显示于仪表。本发明可确定气压传感器是否出现故障,进而提高了通过气压传感器和仪表对待测部件的气压值检测的准确性。
