    Abstract: Vehicles and related systems and methods are provided for controlling a vehicle in an autonomous operating mode. One method involves a controller associated with a vehicle identifying a visual attention state associated with a driver of the vehicle based at least in part on output of an imaging device onboard the vehicle, determining, based at least in part on the visual attention state, a driver lane preference corresponding to an adjacent lane in a visual attention direction relative to a current lane of travel for the vehicle, adjusting a priority associated with the adjacent lane corresponding to the driver lane preference and autonomously operating one or more actuators onboard the vehicle to initiate maneuvering the vehicle from the current lane in a manner that is influenced by the adjusted priority associated with the adjacent lane.

    Abstract: Methods and systems are provided for estimating vehicle parameters of a vehicle. A maximum desired vehicle acceleration and a minimum excitation acceleration in a first direction are determined. The minimum excitation acceleration is associated with generating an estimated vehicle parameter. A first control input for transmission to an advanced driver assistance system (ADAS) to apply a temporary excitation acceleration that is greater than the minimum excitation acceleration and less than the maximum desired vehicle acceleration is generated. The estimated vehicle parameter is generated using a vehicle parameter estimation observation model based on vehicle data received from at least one vehicle sensor. The vehicle data is generated in response to the application of the temporary excitation acceleration to the vehicle. The estimated vehicle parameter is transmitted to the ADAS of the vehicle for replacement of a previous vehicle parameter at the ADAS with the estimated vehicle parameter.

    Abstract: A vehicle configured to execute one or more methods for detecting function of a charging receptacle during a charging cycle. The methods include supplying a charging current through the pins; monitoring a pin temperature of the pins during the charging current; and applying a first step function to the charging current. The methods may also include monitoring a first step change in the pin temperature during the first step function; comparing the first step change in the pin temperature to a first expected temperature change to create a first deviation; and comparing the first deviation to a predetermined threshold. If the first deviation exceeds the predetermined threshold, signaling a maintenance alert, and if the first deviation is less than the predetermined threshold, logging the first deviation.

    Abstract: A braking system includes brake rotors, wheel speed sensors, and an electronic control unit. The brake rotors are couplable to wheels. The brake rotors have rotor thickness variations that cause a vibration while braking. The wheel speed sensors are couplable to the wheels and configured to generate rotation signals for the wheels. The electronic control unit coupled to the wheel speed sensors and configured to generate an absolute phase offset signal that conveys an absolute phase offset angle between the rotor thickness variations in response to the rotation signals, generate a brake torque adjustment signal in response to the absolute phase offset signal and the rotation signals, and adjust a first braking control signal for a first brake rotor relative to a second braking control signal for a second brake rotor based on the brake torque adjustment signal to minimize an amplitude of the vibration during a braking event.
