Embodiment Construction

[0030] The following description is merely exemplary in nature and is not intended to limit the disclosure, its application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0031] As previously mentioned, a camera or additional image sensor is one of the types of sensors that may be used in a vehicle to obtain information that facilitates the autonomous or semi-autonomous operation of the vehicle or alerts the vehicle operator. False signals can interfere with the detection performed by the image sensor. High intensity false signals can also damage the image sensor. For example, although false signals may be unintentional and have naturally occurring sources (eg, sun glare), spoofing is exclusively addressed in this paper for illustration purposes. Spoofing signals are intentionally generated false signals (e.g., using a laser pointer) that negatively affect the operation of ...

Abstract

Systems and methods to mitigate an effect of an errant signal on an image sensor of a vehicle involve collecting light and separating the light to obtain signals at different wavelengths. A method includes determining an intensity of the light at each of the different wavelengths, and identifying the errant signal based on the intensity of the light exceeding a threshold value at an errant signal wavelength among the different wavelengths. The errant signal is mitigated using the controller.

Description

technical field [0001] The subject disclosure relates to mitigation of the effects of errant signals on image sensors of vehicles. Background technique [0002] Vehicles (eg, cars, trucks, construction equipment, farm equipment, automated factory equipment) increasingly include sensors to obtain information about the vehicle and its surroundings. This information facilitates autonomous operation of the vehicle, activation of semi-autonomous systems (eg, collision avoidance, adaptive cruise control, automatic braking) or alerts to the driver. Exemplary sensors include radio detection and ranging (radar) systems, ultrasonic sensors, light detection and ranging (lidar) systems, and cameras, or more generally, image sensors including optical systems. Image sensors are susceptible to false signals. For example, a false signal could be an unintended influence of sunlight or other light sources, or a reflection of a light source. False signals may also be spoofed signals, which ...
