WIPER CONTROL METHOD AND WIPER CONTROL DEVICE
In a wiper device for vehicles, overrun at inversion positions is suppressed while a wind load and a high load are dealt with. A wiper device includes: a wiper blade; a wiper arm to which the wiper blade is attached; and a motor for driving the wiper arm. A load generated in the motor when the wiper blade moves on a windshield is estimated and calculated based on a motor supply current amount and the like. When an outward load generated in the wiper motor exceeds a predetermined threshold value, a high load correction process is performed based on the outward load. When the outward load is less than or equal to the threshold value, a wind load correction process is performed based on a wind load calculated from a difference between the outward load and the return load.
Fault diagnostics in aircraft windshield wiper systems
A windshield wiper system (WWS) is provided. The WWS includes a brushless direct current (BLDC) motor, a wiper arm and blade, a gearbox/converter operably interposed between the BLDC motor and the wiper arm and blade and a smart motor drive configured to determine a WWS failure condition and to operate the BLDC motor according to the determination.
ACOUSTIC EMISSION BASED DEVICE CONTROL
Provided are methods for acoustic emission based device control. Some methods described also include receiving information associated with a first acoustic emission sensor, a second acoustic emission sensor, and a third acoustic emission sensor is received. In embodiments, the information corresponds to an event. In accordance with the first, second, and third acoustic emission sensor information, the first, second, and third timestamps, and a geometry of the surface, a unit vector is calculated from each acoustic emission sensor in the direction of the event's origin. Parameters are calculated based on the unit vectors. Systems and computer program products are also provided.
METHOD AND APPARATUS FOR DETECTING ROAD CONDITION DATA AND WEATHER CONDITION DATA USING VEHICULAR CROWD-SENSING
A method for acquiring road data onboard a vehicle, the road data associated with a segment of road is provided. The method obtains, via vehicle onboard sensors, sensor data associated with current weather conditions, current road conditions, and a physical road state; determines whether the current weather conditions indicate existence of severe weather, whether the current road conditions indicate potential slip, and whether the physical road state indicates one or more road anomalies; generates a road data result, based on existence of severe weather, potential slip, and one or more road anomalies; and transmits the road data result, via a vehicle onboard telematics unit.
FLUID LEVEL SENSOR-ATTACHED MOTOR PUMP FOR WASHER FLUID
The present invention relates to a fluid level sensor-attached motor pump for a washer fluid, in which a fluid level sensor for detecting the remaining amount of a washer fluid stored in a washer fluid reservoir and outputting a detection signal is integrally mounted to a motor pump for a washer fluid so that an operator can check the remaining amount of the washer fluid through a dashboard of a vehicle and thus can replenish an insufficient washer fluid, in which the fluid level sensor is integrally mounted to the motor pump for a washer fluid to solve a problem in that the motor pump and the fluid level sensor are separately wiring-connected to the washer fluid reservoir to thereby deteriorate workability of wiring so that workability of wiring can be increased and the wiring can be simplified to reduce a defective proportion, in which the motor pump for a washer fluid and the fluid level sensor are integrally manufactured so that the manufacturing cost can be reduced, and in which the fluid level sensor for detecting the remaining amount of a washer fluid and outputting a detection signal is manufactured by selecting any one of a combination of a magnet and a Hall sensor, a combination of a magnet and a reed switch, and a combination of a Hall sensor and a buoyancy device mounted with a magnet so that the improvement in performance can be achieved through the use of a magnetic Hall sensor having reliability.
DEVICE AND METHOD FOR CONTROLLING WIPER OF VEHICLE
A device and a method for controlling a wiper of a vehicle. The device may include a wiper actuator for driving the wiper of the vehicle, a sensor for measuring a driving speed of the wiper, and a controller that controls the wiper of the vehicle based on a relationship between a driving voltage applied to the wiper actuator and the driving speed measured by the sensor.
Methods for beam management in vehicle
Methods and apparatus for relay aided beam management in a vehicle communication system are provided. The relay comprises an antenna system including an internal antenna located inside a vehicle and an external antenna located outside the vehicle. The relay further comprises a transceiver operably connected to the antenna system, the transceiver configured to receive, from a base station (BS), a first signal via the external antenna of the antenna system, and receive, from the vehicle, configuration information including at least one of a vehicle speed, or a position of a window of the vehicle or windshield wiper. The relay further comprises a processor operably connected to the antenna system and the transceiver, the processor configured to generate a second signal based on (i) the configuration information and (ii) the first signal, wherein the transceiver is further configured to transmit, to a user equipment (UE), the second signal via the internal antenna.
Apparatus and method for controlling wiper of vehicle
A vehicle wiper control apparatus monitors whether warpage occurs in a wiper strip made of a rubber-elastic material that is provided in a wiper blade. When a wiper of a vehicle is turned off and the warpage occurs in the wiper strip, the control apparatus controls the wiper mechanism to move the wiper blade to a parking position thereby preventing deformation of the wiper strip and maintaining the performance thereof.
