The technology relates to developing a highly accurate understanding of a vehicle's sensor fields of view in relation to the vehicle itself. A training phase is employed to gather sensor data in various situations and scenarios, and a modeling phase takes such information and identifies self-returns and other signals that should either be excluded from analysis during real-time driving or accounted for to avoid false positives. The result is a sensor field of view model for a particular vehicle, which can be extended to other similar makes and models of that vehicle. This approach enables a vehicle to determine when sensor data is of the vehicle or something else. As a result, the detailed modeling allowing the on-board computing system to make driving decisions and take other actions based on accurate sensor information.

At least a portion or a side surface of the at least one optical core assembly protrudes outside of a planar surface of the vehicle roof to facilitate scanning of light. The portion of the at least one optical core assembly that protrudes outside of the planar surface of the vehicle roof also protrudes in a vertical direction by an amount corresponding to a lateral arrangement of the optical polygon element, the oscillating reflective element, and the transmitting and collection optics.

A self-calibrating scanning system and method provides a novel way to eliminate errors in scanning systems, such as lidar or radar detection, using an inertial measurement unit. The system includes an energy transmission source configured to transmit an energy signal through a transmittal area. A detector receives a return energy signal of at least one target object of the energy transmitter source within the transmittal area. The system calculates at least one of the range and position of an object from information relating to at least one of the time and phase of the return energy signal relative to the transmittal energy signal. The spatial or angular displacement of the detector relative to the light source is measured using data from the inertial measurement unit, and at least one of calculated range and position of the object is adjusted based on the spatial or angular displacement of the detector.

A method for obtaining approval of a sensor system for detecting objects in a vehicle's environment includes providing a combined probability distribution for deviations between output data from a sensor system and reference data at the programming level for detecting objects by the sensor system, at the sensor level and/or at the fusion level, sampling deviation combinations and calculating occurrence probabilities for the sampled deviation combinations using the combined probability distribution, subjecting the reference data to the sampled deviation combinations, processing these reference data with a fusion unit, and obtaining fusion results, removing occurrence probabilities from the combined probability distribution from which those fusion results are obtained that satisfy a predefined condition, and obtaining a residual probability distribution, taking the integral of the residual probability distribution and obtaining an absolute error probability, and obtaining approval of the sensor system based on the absolute error probability.

Example embodiments relate to methods and systems for implementing radar electronic support measure operations. A vehicle's processing unit may receive information relating to electromagnetic energy radiating in an environment of the vehicle that is detected using a vehicle radar system. The electromagnetic energy originated from one or more external emitters, such as radar signals transmitted by other vehicles. The processing unit may determine a spectrum occupancy representation that indicates spectral regions occupied by the electromagnetic energy and subsequently adjust operation of the vehicle radar system based on the spectrum occupancy representation to reduce or mitigate interference with the external emitters in the vehicle's environment. In some examples, the vehicle radar system may be switched to a passive receive-only mode to measure the electromagnetic energy radiating in the environment from other emitters.

Systems and methods are described that relate to a scanning laser system configured to emit laser light and an interlock circuit communicatively coupled to the scanning laser system. The interlock circuit may carry out certain operations. The operations include, as the scanning laser system emits laser light into one or more regions of an environment around the scanning laser system, determining a respective predicted dosage amount for each region based on the emitted laser light. The operations further include detecting an interlock condition. The interlock condition includes a predicted dosage amount for at least one region being greater than a threshold dose. In response to detecting the interlock condition, the operations include controlling the scanning laser system to reduce a subsequent dosage amount in the at least one region.
