An advance angle correction method of a motor device includes: acquiring first advance angle correction information indicating a correspondence relationship between an advance angle correction amount and a rotation speed difference of a rotor of the motor calculated in advance based on a rotation speed change rate; measuring the rotation speed difference of the rotor; calculating a first advance angle correction amount for each rotation direction of the rotor as a first forward rotation advance angle correction amount and a first reverse rotation advance angle correction amount so that a rotation speed difference of an output shaft becomes smaller based on the first advance angle correction information and the rotation speed difference of the rotor; and storing the calculated first forward rotation advance angle correction amount and the first reverse rotation advance angle correction amount as advance angle correction information for each motor device.

A control device for a heater that is installed in at least a portion of a member constituting a part of an outer surface of a vehicle and that melts snow of the member by generating heat through energization, the portion through which a radio wave of a radar installed in the vehicle is transmitted, includes: a dirt determination value calculation unit that calculates a dirt determination value for determining whether dirt adheres to an outer surface of the portion of the member based on a reception level of a radio wave received by the radar; and a heater control unit that executes heating control to energize the heater when an outside air temperature is in a predetermined low temperature range and the dirt determination value is equal to or larger than a predetermined threshold value.

A raindrop recognition device is configured to recognize a raindrop on a transparent panel. The raindrop recognition device includes a storage unit, an image input unit, and an image recognition unit. The storage unit stores a trained model that is a machine learning model trained using, as training data, images of the transparent panel with adhered raindrops and images of the transparent panel without adhered raindrops. Image data of the transparent panel taken by a camera is input to the input unit. The image recognition unit is configured to calculate a value representing a raindrop likeness of an object on the transparent panel in the image data by inputting the image data to the trained model. The trained model is trained by training data including images of the transparent panel with uniform background and images of the transparent panel with light source.

A wiper motor including an electrically conductive housing in which a speed reduction mechanism is housed, a motor body housed within a yoke joined to the housing and having a power supply terminal that contacts a commutator so as to supply electric power to a rotor, and having a brush that includes a ground terminal having one end in contact with the commutator and another end connected to an electrically conductive partitioning wall of the housing that covers an opening in the yoke, a power supply line configured to supply electric power to the power supply terminal via a noise-suppression choke coil, a ground line connected to the partitioning wall and to ground, and a capacitor connecting the power supply line with the ground line, such that a noise component flowing through the ground line passes through the choke coil.

The present invention relates generally to the field of camera covers. More specifically, the present invention relates to a vehicle camera cover for exterior cameras of a vehicle. The cover is comprised of a base that is further comprised of a padded magnet or adhesive layer that allows the cover to magnetically or adhesively attach to the exterior surface of a vehicle. A magnetic base layer with a magnetic bottom surface further attaches to the top surface of the magnet layer, and is comprised of a hinge. A transparent lid further attaches to the hinge, wherein the outer surface of the hinge is comprised of a water-repelling coating. Therefore, the cover ensures precipitation or debris cannot obstruct, cover, or damage the exterior cameras of a vehicle, and wherein the cover can be removed as desired without damaging the exterior vehicle surface.

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.
