Periodic, Repetitious Or Successive Operations Control Of Motor, Including "jog" And "inch" Control Patents (Class 318/443)
  • Patent number: 11180117
    Abstract: A wiper is controlled to sweep a surface area, e.g., a portion of a windshield, in front of a camera, e.g., a camera mounted inside a vehicle. An image captured from the camera after the wiper completes, e.g., immediately completes, the sweep of the surface area in front of the camera is used in generating a depth map. In some embodiments a first wiper is controlled to clear a surface area in front of a first camera while a second wiper is controlled to clear a surface area in front of second camera at the same time, and the first and second cameras are synchronized to initiate image capture at the same time, capturing images through recently cleared area, and the captured images are used to generate a depth map. A vehicle control operation, e.g., a direction, braking or speed control operation is performed based on the depth map.

  • Patent number: 10442401
    Abstract: Since a shape of a stator 44 is made mirror symmetric with respect to a rotor 45 as a 4-pole/6-slot type, rotational deflection of the rotor 45 can be suppressed. As the minimum number of poles and the minimum number of slots, which can suppress the rotational deflection of the rotor 45, a frequency of magnetic noises approaches a frequency of mechanical noises. Thus, it is possible to integrate the whole noises generated by the DR-side wiper motor 21 into a low frequency range thereof, and to make the acoustic sensitivity (dB) of a vehicle interior smaller. Since the stator 44 is fixed inside a housing 40 and mounting legs fixed to a vehicle body fixed portion are provided in the housing 40, the stator 40, which is a source of the magnetic noises, can be fixed to a vehicle via only the housing 40. Therefore, a brushless wiper motor with quietness improved further can be designed.

  • Patent number: 8453290
    Abstract: The present invention relates to a wiper apparatus in which it is easy to replace a wiper blade without this leading to any erroneous operation. When a wiper operation has been stopped by a wiper driving apparatus 31, the wiper driving apparatus causes the wiper arms to first move to a housing position and then stops the wiper arms. When wiper blades are to be replaced, an IG switch 33 is turned off during a wiper operation. If the IG switch 33 is turned off while the wiper arms are within a first stopping range, then the wiper arms are stopped at that position and the blades are replaced. If the wiper arms are stopped outside the first stopping range, then they are first moved to a bottom inverted position or a housing position and are then stopped.

  • Publication number: 20130127389
    Abstract: A method for the activation of a windscreen wiper motor is disclosed, in which the motor is connected to a wiper blade by a drive shaft, which moves the wiper blade between two reversal points of a wiping field in differing movement direction, where the rotation speed and direction of the motor, or the speed of the wiper blade, is detected by a sensor device and is supplied to a control device as an input value. The motor, before reaching the respective reversal point, is switched off, whereupon the drive shaft continues to rotate further by a castor angle up to a standstill, and the wiper blade moves further by a trailing distance. The actual speed of the wiper blade is compared at the switch-off time with a nominal speed, and the motor is operated further for a period of time when the comparison results in a difference in values.

  • Patent number: 8441222
    Abstract: A system for measuring current in an H-Bridge motor drive circuit and using that current to determine the output of a device powered by the motor. A particular embodiment is disclosed for a motor-driven fluid pump. Motor current is measured at predetermined pump pressures and flow rates to create calibration tables relating motor current to pump pressure. Once calibrated, the system determines pump pressure based on motor current by referring to the calibration tables. In an embodiment, the pump is driven to achieve a predetermined fluid dispense profile. The system monitors pump pressure by measuring motor current and determines if the dispense profile is being achieved and sets alarms if predetermined thresholds are not maintained. The system also detects pump wear based on the current measurements and issues warnings to the user in such conditions.

  • Patent number: 8347448
    Abstract: An output shaft of a wiper motor is connected to a wiper to transmit a rotational force of the wiper motor to the wiper to reciprocally swing the wiper between an upper return position and a lower return position in response to forward and backward rotations of the output shaft upon energization of the wiper motor. When the wiper is stopped at the lower return position, the control unit executes a stop position holding control operation in such a manner that the control unit controls a rotational direction of the wiper motor to apply a rotational force to the wiper in a downward direction and controls the rotational force of the wiper motor based on a speed of the vehicle to substantially maintain the wiper at the lower return position.

  • Patent number: 8339083
    Abstract: A voltage detection section and current detection section detect a voltage and current supplied to a motor, and the detected voltage and current are supplied to a position detection section. An angular speed output from the position detection section is supplied to a differentiator to output an angular acceleration. A fundamental wave component extraction section extracts a fundamental wave component of the angular acceleration, and the extracted fundamental wave component is supplied to an amplitude adjustment section. The output of the amplitude adjustment section is subtracted from the average current command by a subtraction section. This subtraction result, current detection value, and the rotor position from the position detection section are supplied to a current control section to carry out the current control operation so as to obtain a current command.

  • Patent number: 8324853
    Abstract: A vehicle wiper controller includes a wiper drive circuit which drives a wiper. An operation switch is manipulated in a plurality of manipulation directions or to a plurality of operation mode positions when a manipulation force is applied thereto. A wiper operation control unit electronically controls the operation of the wiper and sets the wiper to an operation mode corresponding to the manipulation of the operation switch. A control signal hold circuit, discrete from the wiper operation control unit, transmits a control signal to the wiper drive circuit when the operation switch is manipulated in a predetermined first manipulation direction or when the operation switch is manipulated to a predetermined first operation mode position. The control signal hold circuit sets a hold state for holding the transmission state of the control signal.

  • Patent number: 8264183
    Abstract: A windshield wiper control unit that controls a windshield wiper based on the position of an operation member, includes: an electric value detection unit that detects an electric value that continuously changes based on the position of the operation member; a setting unit that sets a reference electric value range that is a portion of a variation range of the electric value; a determination unit that determines whether the electric value detected by the electric value detection unit falls within the reference electric value range; and a position determination unit that determines the position of the operation member based on the reference electric value range. When the detected electric value falls outside the reference electric value range, the reference electric value range is updated in such a manner that the electric value, which falls outside the pre-update reference electric value range, falls within the post-update reference electric value range.

  • Patent number: 8112197
    Abstract: A wiper apparatus includes: a wiper blade driven by a first motor; and a wiper blade driven by a second motor. The motors are drive-controlled by control microcomputers, respectively. The control microcomputers are connected to each other through a communication line. While exchanging position information of the wiper blades through the communication line, the control microcomputers synchronously drive the motors on the basis of a position relationship between both of the wiper blades. When an abnormality occurs in a communication state of an in-vehicle LAN, a setting state of a wiper switch is grasped through a switch signal line directly connected to the wiper switch, and wipers are prevented from being stopped when such communication abnormality occurs.
