The invention discloses an automobile seat heating control method and system, and the method comprises the following steps: sampling data fed back by a temperature sensor, and calculating the sampled data to obtain an average value; if the average value is within a preset first threshold range, the heating module is closed; if the average value is within a preset second threshold range, acquiring the sampling temperature corresponding to the average value as the current sampling temperature; the target temperature is set to be compared with the current sampling temperature, the target temperature and the current sampling temperature are substituted into a PID algorithm, a PID output value is obtained through calculation, and a PWM duty ratio value for controlling heating is obtained through calculation according to the PID output value; and a signal corresponding to the PWM duty ratio value is converted into a low-frequency on-off signal through a high-frequency PWM-to-low-frequency on-off algorithm to control the heating wire to supply power. The data volume of parameter adjustment in the seat heating calibration process is reduced, and pulse radiation generated by high-frequency PWM is avoided while self-adaptive temperature adjustment is achieved.

    本发明公开了一种汽车座椅加热控制方法及系统,包括以下步骤:对温度传感器反馈的数据进行采样,并对采样的数据进行计算得到平均值;若平均值在预设的第一阈值范围内,则关闭所述加热模块;若平均值在预设的第二阈值范围内,则获取平均值对应的采样温度作为当前采样温度;设置目标温度以与当前采样温度进行对比,并将目标温度和当前采样温度代入PID算法,计算得到PID输出值并根据PID输出值计算并得到控制加热的PWM占空比数值;通过高频PWM转低频通断算法,将PWM占空比数值对应的信号转化为低频通断信号控制加热丝供电。减少座椅加热标定过程调参的数据量,并且在实现自适应温度调节的同时避免高频PWM产生脉冲辐射。
