AUTOMATIC TRIGGER STRATEGY FOR CLEARING EXTERIOR BIOMETRIC SENSORS

While a vehicle is off, an automatic trigger strategy activates a heating device that melts snow and ice off exterior vehicle sensors as it is needed. The automatic trigger strategy determines when to turn on the heating device while the vehicle is in a limited power state by using data pulled from memory or data obtained from a current data check. Collected, analyzed, and stored during key-off, data pulled from memory allows the invention to accurately choose the correct time to start the heating device without consuming additional power. If current data checks are required because data saved at key-off is not enough information to execute a decision, the invention may determine the least power consuming data checks. A power manager extends a threshold that is dependent on the energy reserve. Once the energy reserve is below the threshold, the power manager inactivates the heating device and voids manual commands.

12030095 · 2024-07-09 · ·

A device and method for protecting an optical sensor of a vehicle are disclosed, wherein the sensor is protected from environmental pollutants which may adhere to an optical surface of the sensor if the sensor is exposed to them, and wherein the environmental pollutants are kept away from the sensor by an ultrasonic cleaning of the sensor surface using an ultrasonic field. The ultrasonic field of the ultrasonic cleaning is emitted by a protection device into the air to provide a protection zone around the optical surface of the sensor such that a contact of the optical surface with the environmental pollutants is avoided, wherein the environmental pollutants are moved and/or destroyed in the air away from the sensor if they enter the protection zone), and wherein the protection zone provides a contactless cleaning of the sensor.

Acousto-vibratory sensor cleaning

Approaches, techniques, and mechanisms are disclosed for sensor cleaning systems. A region of a sensor window is identified to be blocked by an obscurant. The location of the region is determined using the sensor associated with the sensor window. An acousto-vibratory cleaning system receives the location of the region and produces a fluid droplet to be dispensed at a specified point on a two-dimensional plane of the surface of the sensor window. Sonic actuators are activated to capture the fluid droplet in acoustic levitation. Acoustic forces guide the fluid droplet to the region being obscured. Once the fluid droplet is in cleaning position, vibration of the sensor window is activated to incrementally clear the obscurant by vibrating the droplet along the obscurant. The acousto-vibratory cleaning system generates additional acoustic forces to guide the contaminated fluid droplet to a closest drainage canal.

Automatic rain response system

An automatic rain response system includes microphones of a vehicle, windshield wipers, and a controller. The microphones generate acoustic signals in response to rain. The controller is configured to receive a local weather condition, extract acoustic features from the acoustic signals, form feature vectors in response to the acoustic features and the local weather condition, classify the feature vectors to determine a current class among multiple classes, activate the windshield the wipers at a high speed in response to the current class being a heavy rain on a windshield class, activate the windshield wipers at a medium speed in response to the current class being a freezing rain on the windshield class, activate the windshield wipers at a low speed in response to the current class being a light rain on the windshield class, and deactivate the windshield wipers in response to the current class being a no rain class.
