Devices, systems, and methods are provided for enhanced sensor cleaning validation. A device may receive a signal from a sensor indicative of an obstruction on the sensor. The device may activate a cleaning system at a degree of actuation responsive to the obstruction. The device may then obtain a first post-clean performance measurement of the sensor. The device may then adjust the degree of actuation of the cleaning system based on a degradation measurement between a baseline performance measurement associated with a clean performance baseline of the sensor and the first post-clean performance measurement.

In a vehicle wiper apparatus, rotation of an output shaft of a wiper motor is converted to reciprocal rotation of a pivot shaft, and a wiper member, attached to the pivot shaft, reciprocally rotates between closed and open positions. A nozzle, provided in the wiper member, sprays a cleaning fluid towards a front side in an advancing direction of the wiper member on at least one of forward and return paths of the reciprocal rotation. A washer pump supplies the cleaning fluid to the nozzle. A round-trip time of the wiper member is detected based on a detection result of a detecting unit that detects at least a state in which the wiper member is positioned in the closed position. The washer pump is controlled based on a detected round-trip time, and is operated during rotation of the wiper member on at least one of the forward and return paths.

A vehicle windshield wiper and washer activation system that allows the control of these devices from outside the vehicle. A remote switch or switches is provided at a convenient location, such as the side of the fender or in front of the grill. An optional wireless connection may also be provided. In the wireless embodiment, a separate actuating device such as a dedicated transmitter or smartphone is used to control the wipers and the delivery of washer fluid.
