The invention belongs to the technical field of automobiles, and particularly relates to a passenger car seat motor stalling judgment method and device. The judging device comprises a seat controller, a seat adjusting switch, a seat adjusting motor and a Hall sensor. The seat controller is connected with the seat adjusting motor through a wire harness. The seat adjusting switch is connected with the seat controller through a wire harness; the Hall sensor is arranged on the seat adjusting motor. According to the judgment method, a locked-rotor current threshold value of the seat motor is calibrated, and the signal state of the Hall sensor on the seat motor is collected; when the seat controller monitors that the current value of the current seat motor is larger than a locked-rotor current threshold value and a waveform signal of a Hall sensor cannot be monitored within a certain time, the seat controller can judge that the motor is in a locked-rotor state, and drive output control of the motor is cut off; therefore, the problem that the seat motor is damaged by locked-rotor current is solved.
本发明属于汽车技术领域,具体的说是一种乘用车座椅电机堵转的判定方法及判定装置。该判定装置包括座椅控制器、座椅调节开关、座椅调节电机和霍尔传感器;所述座椅控制器与座椅调节电机通过线束连接;所述座椅调节开关与座椅控制器通过线束连接;所述霍尔传感器设置在座椅调节电机上该判定方法通过对座椅电机的堵转电流阈值进行标定,以及对座椅电机上霍尔传感器信号状态的采集,当座椅控制器监测到当前座椅电机的电流值>堵转电流阈值,且一定时间内监测不到霍尔传感器的波形信号,座椅控制器会判定该电机处于堵转状态,切断该电机的驱动输出控制,解决了堵转电流对座椅电机造成损害。
