    Abstract: A method for dynamically adjusting a battery current limit in a system having a battery pack includes determining a battery pack current as a charge current flowing into or a discharge current flowing from the battery pack, and also calculating a time-windowed average current for each of the charge current, the discharge current, and an RMS current of the battery pack. The battery current limit may be dynamically adjusted when any or all of the calculated time-windowed averages exceeds a corresponding calibrated control threshold. The battery current limit is a window-specific current limit that is greater than the calibrated control threshold and less than a static/fixed current limit for the battery pack. A system includes the battery pack, a sensor operable for measuring a current inflow/outflow to/from the battery pack, and a controller programmed to dynamically adjust the battery current limit using the above method.

    Abstract: A full speed range adaptive cruise control system for a host vehicle includes a plurality of sensors that each generate a signal, a memory that includes executable instructions and a processor that executes the executable instructions. The executable instructions enable the processor to detect a target vehicle as being stopped along a route based upon the signals from the plurality of sensors, cause the host vehicle to stop at a distance from the target vehicle, detect the target vehicle moving along the route after the host vehicle has stopped based upon the signals from the plurality of sensors, determine whether a first predetermined period of time has elapsed since the host vehicle has stopped, determine whether a first predetermined condition is satisfied if the first predetermined period of time has elapsed, and cause the host vehicle to move if the system determines that the first predetermined condition is satisfied.

    Abstract: One general aspect includes a system to commence host vehicle movement upon being stopped behind a target vehicle, the system includes a memory configured to include one or more executable instructions and a processor configured to execute the executable instructions, where the executable instructions enable the processor to: detect the target vehicle as being stopped along a route; cause the host vehicle to stop at a first distance from the target vehicle; detect a transition of one or more brake lights of the target vehicle from an ON state to an OFF state; and after the one or more brake lights are detected to transition from the ON state to the OFF state, cause the host vehicle to move at a slow speed in the direction of the target vehicle.

    Abstract: Presented are automated driving systems for intelligent vehicle control, methods for making/using such systems, and motor vehicles equipped with such automated driving systems. A method for executing an automated driving operation includes: determining path plan data for a subject motor vehicle, including current vehicle location and predicted route data; receiving, from a network of sensing devices, sensor data indicative of current object position and object dynamics of a target object; applying sensor fusion techniques to the received sensor data to determine a threat confidence value that is predictive of target object intrusion with respect to the vehicle's location and predicted route; determining if this threat confidence value is greater than a calibrated threshold value; and, responsive to the threat confidence value being greater than the calibrated threshold value, transmitting one or more command signals to one or more vehicle systems (e.g., powertrain, steering and/or brake system) to take preventive action.

    Abstract: A battery system may include a plurality of subdivisions, such as battery cells or sub-packs. A measurement system configured to determine a subdivision electrical parameter associated with each of a plurality of subdivisions. A battery control may identify a subdivision satisfying a criterion based on the plurality of subdivision electrical parameters. According to some embodiments, the battery control system may determine a ratio of the subdivision electrical parameter of the identified subdivision to the electrical parameter of the battery pack. The ratio may be used to scale the electrical parameter associated with the battery pack by the ratio. According to other embodiments, the subdivision electrical parameter associated with the identified subdivision may be provided to a battery state estimation system. The scaled electrical parameter or the electrical parameter associated with the identified subdivision may be used by a battery state estimation system to generate an estimated battery state.
