Alternative wiper mechanism to remove rainwater on a sensor enclosure
A sensor enclosure comprising a domed cover and a base. The base can be encased by the domed cover. The base comprises an inner frame, an outer frame, one or more wipers, and a powertrain. The inner frame can provide surfaces for one or more sensors. The outer frame, disposed underneath the inner frame, the outer frame includes a slewing ring. The slewing ring comprises an inner ring to which the domed cover is attached and an outer ring attached to the outer frame. The one or more wipers extends vertically from the outer frame, each wiper having a first end attached to the outer frame and a second end attached to a support ring, and each wiper making a contact with the dome cover. The powertrain, disposed within the outer frame, configured to rotate the ring and the dome cover attached to the inner ring.
Method for Determining a Sensor Degradation Status
A method for determining a sensor degradation status of a first sensor system includes: providing data of the first sensor system to represent the environment; providing data of a second sensor system to represent the environment; determining an individual blindness indicator for the first sensor system on the basis of sensor data exclusively of the first sensor system; determining at least one first environment-related determination variable based on the provided data of the first sensor system; determining at least one second environment-related determination variable based on the provided data of the second sensor system; determining a fusion blindness indicator based on a comparison of the at least one first environment-related determination variable with the at least one second environment-related determination variable; and determining the sensor degradation status of the first sensor system based on of the individual blindness indicator and the fusion blindness indicator.
Sensor Device and Driver Assistance System
A sensor device includes at least one sensor unit, which is configured to detect a detection area; at least one through element, wherein the at least one sensor unit is configured to detect the detection area through the at least one through element; at least one temperature sensor on or in at least one through element, the at least one temperature sensor being configured to detect a temperature of the at least one through element; at least one heating unit, which is configured to heat the at least one through element; and a controller, which is connected to the at least one temperature sensor and the at least one heating unit and which is configured to control the at least one heating unit based on the temperature detected by the at least one temperature sensor.
Ultrasonic sensor
A shield member electromagnetically shielding at least part of an electric circuit has a first end and a second end. The first end is configured to be constantly connected to a ground wire to electromagnetically shield at least part of the electric circuit; and the second end is configured to be selectively connectable to a power source, the shield member being configured to generate heat when energized while the second end is connected to the power source. Accordingly, the shield member electromagnetically shielding at least the part of the electric circuit can serve as a heater for preventing freezing and snow attachment.
Cleaning unit for cleaning foreign matter from a cover, in particular a cover of a transmitter/receiver window of a driving environment sensor, and device for sensing the environment and method
A cleaning unit for cleaning foreign matter from a cover, in particular a cover of a transmitter/receiver window of an environment sensor, including at least one movable wiper blade, which is arranged so as to wipe off foreign matter such as water or dirt on the cover by movement along the cover. For this purpose, the wiper blade touches the cover for example with one or multiple rubber lips. The wiper blade is positioned in an inclined manner with respect to a direction of movement of the wiper blade and is thus movable in such a way that a force exerted by the moved wiper blade on the foreign matter has a component in the direction of the force of gravity. Also described is a related device for sensing the environment as well as a method for cleaning a cover.
RANGING APPARATUS
A ranging apparatus is provided which is mountable to a vehicle and emits a transmit wave and receives a reflected wave arising from reflection of the transmit signal from an object to calculate a distance to the object. The ranging apparatus includes a light transmissive window, a heater, and a controller. The light transmissive window permits at least one of the transmit wave and the reflected wave to pass through. The heater works to add thermal energy to the light transmissive window. The controller uses an ambient temperature outside the ranging apparatus and a speed of the vehicle derived from a vehicle speed sensor to control energization of the heater. When the vehicle speed sensor is malfunctioning, the controller controls the energization of the heater as a function of the ambient temperature without use of the speed of the vehicle.
DE-ICING SYSTEM FOR A SENSOR
A de-icing system for a sensor is provided. The de-icing system has a heating element for tempering a fluid, a flow generator for driving a fluid, and a cover element, which separates an external area from an internal area. The cover element is configured in such a way that a fluid driven by the flow generator flows along the cover element, in order to heat the cover element up.
Transmissive front-face heater for vehicle sensor system
A heater for vehicular sensors is configured to pass sensing energy and thereby permit placement of the heater directly over the sensing area in the path of the sensed energy. In this way, direct heating of the sensing area is provided minimizing the energy necessary to prevent icing and improving deicing speed.
