The invention discloses an electric vehicle tire pressure monitoring method and system, and the method comprises the steps: obtaining a wheel speed signal of a front wheel of an electric vehicle through a wheel speed sensor installed at the front wheel of the electric vehicle, and obtaining a wheel speed signal of a rear wheel of the electric vehicle through a wheel speed sensor installed at the rear wheel of the electric vehicle; transmitting the wheel speed signal of the front wheel of the electric vehicle and the wheel speed signal of the rear wheel of the electric vehicle to a processing unit; enabling the signal processing unit to process the received wheel speed signals based on a frequency domain method and a wheel speed comparison method and judging whether the tire pressure of front and rear wheels of the electric vehicle is normal or not. Wheel speed signals are processed and calibrated in a mode of combining a frequency domain method and a wheel speed comparison method, whether the tire pressure of the electric vehicle is normal or not is monitored, repeated proofreading is carried out before alarming to the maximum extent, the accuracy is effectively improved, and the false alarm rate is reduced. According to the invention, the riding safety of the electric vehicle is improved, the probability of accidents is reduced, and the intensified tire wear and the reduced endurance mileage caused by the pressure loss of the tire are avoided.
本发明公开一种电动车胎压监测方法及系统,该方法包括:通过在电动车前轮安装的轮速传感器获得电动车前轮的轮速信号,通过在电动车后轮安装的轮速传感器获得电动车后轮的轮速信号;将所述电动车前轮的轮速信号和电动车后轮的轮速信号传输给处理单元;所述信号处理单元基于频域法和轮速比较法对收到的轮速信号进行处理,判断电动车前后车轮的胎压是否正常。本发明通过频域法和轮速比较法相结合的方式对轮速信号进行处理与标定,监测电动车胎压是否正常,最大限度的在报警前进行反复校对,有效的提高了准确率,降低了误报率。本发明提升了电动车骑行的安全性,减少事故的发生概率,避免在轮胎失压时造成的轮胎磨损加剧和续航里程减少。
