A motor device includes a motor having three-phase windings; a rotation speed detector detecting a rotation speed of the motor; a drive signal generator controlling a duty ratio not to exceed a duty ratio upper limit value, and performing control for an energization angle of each phase and performing advance angle control shifting the phase from a reference position to generate a drive signal corresponding to the duty ratio; and an inverter supplying alternating current to the windings based on the drive signal. The drive signal generator includes an advance angle/energization angle controller changing the energization angle to 120 degrees or less while performing advance angle control when the duty ratio is equal to or greater than the duty ratio upper limit value and the rotation speed is equal to or less than a predetermined threshold value in a state where the energization angle is greater than 120 degrees.

Provided are embodiments for a direct drive wiper system. The system includes a motor that is operably coupled to a wiper system to drive one or more wiper arms of the wiper system, and a gearbox, wherein an input to the gearbox is coupled to the motor and an output of the gearbox is coupled to the wiper assembly, wherein the gearbox is configured to convert an input from the motor to an output to drive the wiper system. The system also includes a brake and stopper mechanism that is coupled to the gearbox and the wiper system. Also provided are embodiments for a method for operating the direct drive wiper system.

When a first driver setting mode indicates an “OFF mode” or an “AUTO mode,” a VP accepts a light operation mode request from an ADK. When an operation is performed by a user, the VP changes an operation mode of a headlight in accordance with the operation by the user. When the operation by the user has not been performed, the VP changes the operation mode of the headlight in accordance with the light operation mode request.

The present invention relates to a wiper system for a glazed surface, with at least one main body which includes at least one blade rubber designed to come into contact with the glazed surface and at least one embedded motorized member for setting in motion, which is configured to drive a linear movement of the main body along the glazed surface.
