Abstract: An autonomous vehicle (AV) navigates with limited calibration of sensors and other components. To navigate with a less-reliable sensing and control capacity, the AV uses sensors to detect a navigation path within the environment of the AV. The navigation path may include encoded information describing a destination or distance to information, which may be decoded by the AV to select a navigation path or determine movement of the AV along the path. To control movement of the AV along the path, the AV may monitor the navigation path after the AV executes a motion plan to determine the relative motion of the navigation path within the sensor data. The navigation path moving towards or away from a sensor may be used to determine whether the AV is moving towards or away from the navigation line despite relatively unknown sensed characteristics of the environment or actual movement in the environment.

Abstract: A sensor calibration evaluation system evaluates the quality of control point detection by translating a control object within a scene by a measured amount to generate a sequence of sensor views of the scene as the control object is translated by a known (measured) amount. The control points within each of the sequence of sensor views are detected with a control point detection algorithm. By detecting the control points and determining the detected movement of the control points, a correlation between the measured movement and detected movement can be determined and represent the quality of the control point detection given the set of detection conditions.

Abstract: A battery module includes a first battery cell and a neighboring second battery cell, and an insulating member positioned therebetween. The battery module also includes a battery module enclosure surrounded by an external environment and configured to house each of the first battery cell, the second battery cell, and the insulating member. The battery module additionally includes a battery module cover mounted to the battery module enclosure. The battery module cover includes a vent feature configured to expel high temperature gases from the first battery cell and divert the high temperature gases away from the second battery cell directly to the external environment. The cover is thereby configured to minimize transfer of the high temperature gases from the first battery cell to the second battery cell and control propagation of a thermal runaway event in the battery module.

Abstract: A battery electric system includes a battery, sensor suite, and controller. The sensor suite includes a current sensor, voltage sensor, and temperature sensor. The controller is operable for determining an estimated open circuit voltage of the battery at different time points using a current signal and a voltage signal from the current and voltage sensors, and an equivalent circuit model (ECM). The controller determines an ECM-based state of charge (SOC) of the battery at the different time points, via a calibrated SOC map, using the open circuit voltage and temperature, and calculates a sensor gain value using the ECM-based SOC and a coulomb counting-based SOC, both at the different time points. A control action is executed with respect to the battery when the sensor gain value exceeds a predetermined gain fault threshold, including generating a fault notification signal indicative of a fault of the current sensor.
