The system comprises a controller, an electronic data processor, or both that are configured to control the wiper motor consistent with an operator-defined wiping intensity request. A user interface is configured to input the operator-defined wiping intensity request. In a learning mode, the electronic data processor can learn or record the operator-defined wiping intensity request associated with a respective operator identifier for a series of sampling intervals during operation of the vehicle. First, in the learning mode, a windshield clarity detector is configured to detect an observed clarity state of the windshield of a vehicle for the series of respective sampling intervals to augment the operator-defined wiping intensity request associated with a respective operator identifier. Second, in the learning mode for the series of sampling intervals, the electronic data processor configured to store in a data storage device the augmented observed clarity state of the windshield, and the operator-defined wiping intensity that are associated with a respective operator identifier.

A computer-implemented method causes data processing hardware to perform operations including, based on adjustment of a power mode of a vehicle from an ON state to an OFF state, and based on a current operation mode of a wiper system of the vehicle including an active state, storing the current operation mode of the wiper system. The operations also include, based on the stored current operation mode including the active state, and responsive to adjustment of the power mode of the vehicle from the OFF state to the ON state, operating the wiper system in an inactive state and generating a notification to a vehicle user. Furthermore, the operations include, based on the stored current operation mode being the active state, and responsive to passage of a threshold period of time after generating the notification to the vehicle user, operating the wiper system in the active state.

A vehicle includes a glass clearing system that performs method of clearing a glass surface of a vehicle. The vehicle includes a glass surface. The glass clearing system includes a glass clearing device and a processor. The glass clearing device is configured for clearing a glass surface. The processor receives a signal from a remote device indicative of an instruction for operating the glass clearing device, selects the glass clearing device, and activates the glass clearing device to clear the glass surface based on the instruction.

A wiper washer control apparatus includes an ignition sensor, a shift position sensor, a wiper driving unit, a washer spraying unit, a wiper lever detection unit, and a wiper washer control unit. The wiper washer control unit changes a control to be performed by the wiper driving unit to a delay mode when receiving information indicating that the traveling driver is in the started state from the ignition sensor, receiving information indicating that a shift position is in a parking range from the shift position sensor, and receiving information indicating that the delay mode is to be started from the wiper lever detection unit. The wiper washer control unit changes the control to be performed by the wiper driving unit to a spray mode when receiving, in the delay mode, information indicating that the spray mode is to be started from the wiper lever detection unit.

A system includes a dome, a wiper assembly, a position sensor and a control device. The wiper assembly includes a wiper blade configured to rotate around the dome. The position sensor may be configured to send a signal to a control device when a wiper blade passes the position sensor. The control device may include one or more processors configured to receive the signal from the position sensor and determine a location of the wiper blade relative to the dome based on the received signal.

Systems and methods for estimating wiper friction in a vehicle can include receiving, by a processor, sensor data indicating electrical power input to a wiper motor and a position of a wiper blade coupled to the wiper motor. Calculating, by the processor, an estimated wiper friction based on an energy balance model using the electrical power input and changes an energy of the wiper blade. Determining, by the processor, an average friction power loss over a defined calculation window of wiper blade movement. The method can also include providing, by the processor, the average friction power loss as an input to an automatic wiper control system.

A vehicle includes a front windshield wiper and a front windshield wiper actuator configured to actuate the front windshield wiper to wipe a front windshield of the vehicle. The vehicle includes a rear window wiper and a rear window wiper actuator configured to actuate the rear window wiper to wipe a rear window of the vehicle. A precipitation sensor configured to sense precipitation in front of the vehicle. A control system is configured to control a frequency of the front windshield wiper actuator and a frequency of the rear window wiper actuator based on an output of the precipitation sensor. The frequency of the rear window wiper may be proportional to the frequency of the front windshield wiper with adjustments for inputs such as vehicle speed, camera outputs, and current drawn by the rear window wiper actuator.
