The embodiment of the invention relates to the technical field of tire pressure detection, and discloses a tire pressure detection method, a tire pressure sensor and a storage medium, and the method comprises the steps that the current acceleration of a wheel is acquired, the current acceleration is cached to a sampling window, and the length of the sampling window does not exceed a preset length; according to the acceleration sequence in the sampling window, whether the vehicle is in a driving state or not is judged, and at least two accelerations in the acceleration sequence are different; and if the vehicle is in the running state, controlling a tire pressure sensor to improve the tire pressure detection frequency. The multiple accelerations of the wheels are cached by using the sampling window, misjudgment caused by too few acceleration detection times is reduced, whether the vehicle is in the driving state or not is determined through the acceleration sequence, the offset error of the sensor does not need to be considered, the offset error does not need to be calibrated, the detection of the motion state of the tire pressure sensor is more sensitive, and the driving safety is improved.

    本申请实施例涉及胎压检测技术领域,公开了一种胎压检测方法、胎压传感器及存储介质,其中方法包括:获取车轮的当前加速度,并将所述当前加速度缓存至采样窗口,其中,所述采样窗口的长度不超过预设长度;根据所述采样窗口中的加速度序列,判断车辆是否处于行驶状态,其中,所述加速度序列中至少两个加速度不同;若所述车辆处于行驶状态,则控制胎压传感器提高胎压检测频率。本申请使用采样窗口缓存车轮的多个加速度,降低加速度检测次数过少导致的误判,且通过加速度序列确定车辆是否处于行驶状态,不需要考虑传感器的偏置误差,不需要校准偏置误差,检测胎压传感器的运动状态更灵敏,以提升行车安全。
