The embodiment of the invention provides a tire pressure control method and a tire pressure control device, and relates to the technical field of tire pressure control. The first state signal comprises a current vehicle speed, a current brake pedal position, a current driving mode, a current lateral acceleration, a current driving torque rotating speed, a current four-wheel pulse signal, a current four-wheel speed, a current forward acceleration, a current road surface temperature and a current tire pressure; calculating according to the first state signal to obtain a second state signal, wherein the second state signal comprises a current tire pressure change value, a current road adhesion coefficient, a current wheel bearing weight and a current braking deceleration; and finally adjusting the tire pressure according to the first state signal and the second state signal. According to the method, various state signals during vehicle driving are comprehensively considered, the appropriate tire pressure is comprehensively obtained and adjusted in real time, the method adapts to complex driving scenes, and the safety and comfort of vehicle driving are improved.

    本发明实施例提供了一种胎压控制方法及控制装置,涉及胎压控制技术领域,胎压控制方法首先获取车辆的第一状态信号,第一状态信号包括当前车速、当前制动踏板位置、当前驾驶模式、当前侧向加速度、当前驱动扭矩\转速、当前四轮脉冲信号、当前四轮轮速、当前前进加速度、当前路面温度和当前轮胎胎压;再由第一状态信号计算得到第二状态信号,第二状态信号包括当前胎压变化值、当前路面附着系数、当前车轮承载重量和当前制动减速度;最后根据第一状态信号和第二状态信号调整轮胎气压。即本发明全面考虑车辆行驶时的多种状态信号,综合得出合适的胎压并进行实时调整,适应复杂的驾乘场景,提高汽车行驶的安全性和舒适性。
