A windshield wiper system includes a wiper arm, a wiper blade attached to the wiper arm, an output shaft attached to an end of the wiper arm, an actuator attached to the output shaft, a controller, a first sensor, a second sensor, and a third sensor. The controller is configured to activate the actuator, causing the output shaft to rotate and thus driving the wiper arm with the attached wiper blade in a sweeping motion across a windshield. The controller is also configured to receive signals from the first, second, and third sensors indicating the position of the wiper arm and the wiper blade.

A wiper linkage system directly transmits rotating force of a motor to one wiper arm. The wiper linkage system includes: a gear housing installed on a wiper motor, a pipe rod installed on the gear housing, a crank arm installed on an output shaft of the wiper motor, a first wiper arm installed on a first end of the crank arm by a rotating shaft, a pivot housing assembled with the pipe rod, and a second wiper arm operated by a link structure including a link unit coupled to a second end of the crank arm and the pivot housing. In particular, a first end of the pipe rod is fixed to a vehicle body by a pipe mounting.
