Vehicles and related systems and methods are provided for controlling a vehicle in an autonomous operating mode. One method involves identifying a stationary object outside a current lane of travel based at least in part on sensor data captured onboard the vehicle, determining an estimated location for the stationary object based at least in part on the sensor data and a location of the vehicle and providing the estimated location to a remote system. The remote system updates lane preference information corresponding to the estimated location for the stationary object when the stationary object satisfies one or more avoidance criteria. The method continues by determining a trajectory for a vehicle to change lanes based at least in part on the updated lane preference information and autonomously operating one or more actuators onboard the vehicle in accordance with the trajectory.

Vehicle systems and related methods with autonomous courtesy avoidance

A battery cell by-pass circuit that has particular application for by-passing cells in a high voltage battery for a vehicle. The battery includes a plurality of battery cells electrically coupled in series. The by-pass circuit includes a first switch electrically coupled in series with one or more of the battery cells, a by-pass line electrically coupled around the one or more battery cells and a second switch electrically coupled in the by-pass line and in parallel with the one or more battery cells. During normal cell operation, the first switch is closed and the second switch is open so that current flows through the one or more battery cells. If the one or more battery cells fail or are failing, the first switch is opened and the second switch is closed so that current by-passes the one or more cells and they are removed from the battery circuit.

Battery fault tolerant architecture for cell failure modes series bypass circuit

A by-pass circuit for a battery system that disconnects parallel connected cells or modules from a battery circuit or controls the current through the parallel connected cells or modules. If a cell has failed or is potentially failing in the system, then the by-pass circuit can disconnect the cell or module from other cells or modules electrically coupled in parallel. If a cell or module has a lower capability than another cell or module, then the by-pass circuit can control the current to the cell or module to maximize the performance of the system and prevent the system from creating a walk-home condition.
