The present teaching relates to method, system, medium, and implementations for detecting a need for sensor adjustment. Information is received from an inertial measurement unit (IMU) attached to a sensor, including one or more measurements associated with the IMU, where the sensor is deployed on a vehicle for sensing surrounding information to facilitate autonomous driving. The one or more measurements are analyzed with respect to one or more corresponding known measurements of the IMU. The discrepancy between the one or more measurements and the one or more corresponding known measurements is used to determine whether an adjustment to the sensor is needed.

System and method for detecting sensor adjustment need

The present teaching relates to method and system for sensor protection. A sensor protection system includes an assembly having a first structure embedded in a second structure, wherein a sensor is firmly placed in the first structure for sensing information through the assembly and protected from negative impact of outside environment, and one or more devices mounted on the second structure for providing means to clean a slanted surface of the second structure through which the sensor senses the surrounding information, wherein the one or more devices can be individually or jointly activated as needed to clean the slanted surface in order to prevent degradation of information sensed by the sensor through the assembly.

The present teaching relates to method, system, and implementations for glare control. A sensor housing assembly is provided on an autonomous vehicle to house at least one sensor therein and protect the at least one sensor from negative impact from an environment including glare from the environment that prevents the at least one sensor from capturing accurate information regarding a field of view with respect to the environment to facilitate autonomous driving of the autonomous vehicle. The negative impact on the at least one sensor is determined by a controller, which then activates a glare blocking mechanism in response to the determined negative impact. The glare blocking mechanism being mounted on the sensor housing assembly and configured to assist in blocking glare with respect to the at least one sensor.

System and method for sensor system against glare and control thereof

The present teaching relates to method and system for an assembly for protecting a sensor. The assembly includes a first structure having a rectangular prism and connected with a truncated tube, wherein the rectangular prism and the truncated tube have parallel longitudinal axes and the tube is truncated to yield a cross section having a norm that forms an angle with the longitudinal axis of the truncated tube and a second structure of a trapezoid prism having a longitudinal axis parallel to the longitudinal axes and with the first structure embedded therein. The second structure has a slanted surface in the front that meets the cross section of the truncated tube and has the norm of the cross section.

System and method for a sensor protection assembly

The present teaching relates to method, system, medium, and implementation for sensor protection. It is determined whether a cleaning operation needs to be applied to a portion of a sensor assembly deployed on a vehicle and hosting a sensor therein to acquire information of a surrounding through the portion to facilitate autonomous driving. If the cleaning operation is to be applied, at least one type of cleaning is selected to be carried out by one or more devices mounted on the sensor assembly with respect to the portion. For each of the devices, needed control signal is generated for activating the device to perform a cleaning task the device is configured for and sent to the device to clean the certain portion of the sensor assembly in order to prevent degradation in the information acquired by the sensor through the portion.
