The invention provides an automatic tire pressure control method and device and an inflation/exhaust pump. The method comprises the steps that whether first current tire pressure of a tire reaches an inflation control condition or not is judged according to a first difference value between the first current tire pressure of the tire and preset target tire pressure; if the first current tire pressure reaches an inflation control condition, an inflation grade corresponding to the first difference value is obtained, and inflation duty ratios corresponding to different inflation grades are different; and inflating the tire according to the inflation grade until the tire pressure of the tire reaches the target tire pressure. According to the invention, the tire is inflated according to different first difference values between the first current tire pressure of the tire and the preset target tire pressure by adopting different inflation grades, so that the problem of overinflation caused by full-power inflation in the process of executing automatic inflation of the tire is effectively avoided; the driving safety of the automobile can be improved, the driving oil consumption of the automobile is reduced, and the driving experience of a user is improved.

    本发明提供了一种轮胎自动胎压控制方法、装置及充/排气泵,所述方法包括:根据轮胎的第一当前胎压与预设的目标胎压的第一差值判断所述第一当前胎压是否达到充气控制条件;若所述第一当前胎压达到充气控制条件,则获取与所述第一差值对应的充气等级,不同充气等级对应的充气占空比不同;根据所述充气等级为所述轮胎进行充气,直至所述轮胎的胎压达到目标胎压。本发明根据轮胎的第一当前胎压与预设的目标胎压的第一差值的大小不同,采用不同的充气等级为轮胎进行充气,有效避免了轮胎在执行自动充气过程中采用全功率充气造成的过充的问题,可以提高汽车的行车安全和降低汽车的行车油耗,提高用户的行车体验。
