A windshield wiper system for an aircraft is provided and includes a motor, an output shaft, a wrap spring and crank rocker mechanism (WSCRM) to which the motor and the output shaft are coupled and a controller. By way of the WSCRM, first directional rotation input to the WSCRM from the motor via a two-stage gear reduction is converted such that the output shaft drives wiper blade oscillation through a first sweep angle and second directional rotation input to the WSCRM from the motor is converted such that the output shaft drives wiper blade oscillation through a second sweep angle. The controller is configured to control the motor such that the first directional rotation is continuously or non-continuously input during first or second flight conditions, respectively, and the second directional rotation is continuously input during third flight conditions.

VEHICLE WIPER DEVICE AND VEHICLE WIPER DEVICE CONTROL METHOD

Provided is a vehicle wiper device including (i) a first motor that includes a first output shaft, that rotates the first output shaft to rotate a wiper arm back and forth about a pivot point of the wiper arm, and that causes a wiper blade coupled to a leading end portion of the wiper arm to perform a back and forth wiping operation between an upper return position and a lower return position on a windshield, (ii) a second motor that changes a wiping range on the windshield by the wiper blade, (iii) a rotation angle detector that detects a rotation angle of the first output shaft, and (iv) a controller that controls the second motor according to a rotation angle of the first output shaft detected by the rotation angle detector in a state in which a broad field of view should be secured on a front passenger seat side.

Wiper control mechanism

A method to reduce refreezing of meltable snow includes configuring a wiper arm to wipe the meltable snow from an ambient-facing surface of a window positioned on a vehicle. The method also includes configuring a sensor coupled to the wiper arm to gather and transmit a parameter on the vehicle and environment. The method also includes configuring a processor to receive the parameter, determine refreezability of the meltable snow based on the parameter, and define an action to be performed by the wiper arm.

Vehicle accessory operation based on motion tracking

A vehicle includes a vehicle computing system (VCS) and a vehicle accessory system that may be a window wiper mechanism, a power lift gate, a door lock mechanism, a convertible mechanism or a sunroof mechanism. The VCS communicates with an activity tracking band worn on a wrist of a vehicle occupant. The activity tracking device detects motion of the wrist of the occupant, and is capable of exchanging that data with the VCS. The VCS generates at least one output signal based on data from the activity tracking device. For example, a controller may activate a window wiper mechanism based on signals indicative of a detected long wiping motion.
