Abstract: A method for testing a perception system is disclosed. The method includes detecting, by a processor, one or more objects in a composite image, the composite image including a first image and at least a portion of a second image. A first set of objects are detected in the first image. Further, the method includes comparing, by the processor, a second set of objects of the one or more objects detected in the portion of the second image with a set of previously detected objects in the portion of the second image. Furthermore, the method includes validating, the performance of the processor in the detection of the first set of objects in the first image by ensuring the second set of objects detected in the at least a portion of a second image matches the set of previously detected objects in the portion of the second image.

Abstract: A Light-detection and ranging (LIDAR) system for controlling a bias voltage is provided. The LIDAR system includes a light source configured to emit light pulses and a light sensor configured to receive light pulses transmitted by the light source and scattered by an object. A voltage source is provided to apply the bias voltage to the light sensor. The LIDAR system further includes a sensor configured to generate a signal indicative of a temperature of the light sensor. The LIDAR system includes a controller communicably coupled to the light source, the light sensor, the voltage source and the sensor. The controller is configured to receive the signal indicative of the temperature of the light sensor. Further, the controller is configured to measure the bias voltage currently applied to the light sensor. The voltage source is regulated based at least on the temperature of the photodiode and the measured bias voltage currently applied to the light sensor.

Abstract: A method of estimating an initial rotor position of a switched reluctance (SR) machine having a rotor and a stator is provided. The method may comprise the steps of driving a phase current in each of a plurality of phases of the SR machine to a predefined limit, performing an integration of a common bus voltage associated with each phase, determining a flux value for each phase based on the integrations, and determining the initial rotor position based on the flux values.

Abstract: A control system for a generator of an electric drive is provided. The control system may include a converter circuit configured to communicate with one or more phases of a stator of the generator, and a controller in communication with the converter circuit and an engine associated with the electric drive. The controller may be configured to determine an operational state of the electric drive based on at least engine speed, and engage one of a map-lookup control scheme and a fixed-theta off control scheme for operating the generator based on the operational state of the electric drive.
