A motor device is provided that includes a motor, a drive signal generation portion configured to control a duty ratio indicating a drive output of the motor so as not to exceed a duty ratio upper limit value and generates a drive signal in accordance with the duty ratio, an inverter configured to output an output signal to rotationally drive the motor, a rotation speed detection portion configured to detect a rotation speed of the motor, an acceleration detection portion configured to detect whether the motor is accelerating or not, and an upper limit value setting portion configured to change the duty ratio upper limit value when a rotation speed of the motor exceeds a first threshold value and the motor is rotating under acceleration. The upper limit value setting portion sets the first upper limit value to gradually increase in accordance with an increase in the rotation speed.

The present disclosure relates to methods and systems for generating a trained learning algorithm configured to predict the presence of environmental conditions in image data, a vehicle for utilizing the algorithm, as well as methods and systems for generating the training data for the automated supervised training of a learning algorithm. In some embodiments the training data is in the form of labelled images generated by a camera device arranged on a vehicle, where the labels are indicative of an environmental sensor activation or deactivation signal, or a user-input signal which serve as a supervisory signal for the training of the learning algorithm.

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.

Ranging devices and vehicles include a LiDAR. The LiDAR is fixed to an inside of a vehicle cover, and a field of view of the LiDAR forms a projection area on the vehicle cover. A cleaning range of a wiper of the vehicle at least partially coincides with the projection area. Methods for cleaning a window of a LiDAR for a vehicle includes: regulating operating parameter of at least one of the wiper or the LiDAR such that a cleaning operation of the wiper cooperates with a detection operation of the LiDAR; and controlling the wiper to perform the cleaning operation.

A vehicle includes at least one camera configured to photograph an image around the vehicle, a memory configured to store image data input from the at least one camera, and a controller. The controller is configured to determine that a foreign material is present on the at least one camera and to output a warning message to a user when a brightness change rate of at least one pixel among each pixel of an image frame included in the image data is less than or equal to a reference value and is lower than an average brightness of other pixels except for the at least one pixel.

An imaging apparatus includes a receptacle, a lens that is received in the receptacle and has one surface exposed to an exterior of the receptacle as an exposed surface to capture light from the exterior of the receptacle, an imager that is disposed within the receptacle and inward from the lens and is configured to capture images of the exterior of the receptacle based on light captured by the lens, an imager substrate that is disposed within the receptacle and inward from the lens and is configured to control the imager, a wiper device that includes at least one lens wiper to wipe the exposed surface of the lens. Each of the at least one lens wiper includes a wiping member that includes a wiper rubber and a wiper blade, and the wiping member is positioned on the exposed surface of the lens in a standby mode, in which mode driving of the wiper device is suspended, thereby partially obstructing the light incident on the lens.

A product [11] includes a foldable clamshell-type housing [10] folded to a closed position to contain a pre-formed sensor pad [17] that was formed in situ therein when the housing [10] was in an open position, prior to closing. The housing [10] has an enclosed volume [12] bounded by relatively thin and flexible walls [23, 34], and outwardly extending tabs [18] which facilitate opening. This structure enables the user to easily open the housing [10] to remove the sensor pad [17], a cured silicone composition, by pushing inward on an outer surface of the outer wall [34] of a base section [15] of the housing [10]. This product [11] reduces the amount of manipulation needed to place the sensor pad [17] in a desired position, for example, during installation of a rain sensor system for a vehicle windshield.

A wiper control device includes: a wiper element; and a drive unit configured to control on/off of the wiper element. The drive unit is configured to decelerate a wiper by switching the wiper element from on to off to stop power supply from the wiper element to a motor of the wiper when a wiper angle reaches a deceleration start angle. The drive unit is configured to resume the power supply from the wiper element to the motor by switching the wiper element from off to on after the wiper angle reaches the deceleration start angle.
