The utility model discloses automobile windshield wiper state detection device includes treater, pivot angle detection module and electric current detection module, and pivot angle detection module detects the amplitude of fluctuation of windshield wiper to the finishing ware sends the pivot angle signal in view of the above, and when the pivot angle signal was less than the setting value, the pivot angle undersize that the windshield wiper will be indicateed to the treater was in order to let the driver can in time change the working?effect that rain brush piece improves the windshield wiper, current detection module detects the current value of motor to the finishing ware sends the current signal in view of the above, if the treater receive only when having the electric current to flow through the motor the current signal and do not receive the pivot angle signal, explain then that the motor changes stifled, thereby the treater sent alarm signal suggestion driver motor and changeed stifled this moment, the
