Abstract: Various disclosed embodiments include illustrative controller units, vehicles, and methods. In an illustrative embodiment, a controller unit includes a processor and a memory. The memory is configured to store computer-executable instructions configured to cause the processor to receive a request to perform a mechanical load transition between a motor and a mechanical load, send a torque request to the motor responsive to the received request, receive a motor speed value, determine status of the mechanical load transition responsive to the received request and the motor speed value, and output the determined status.

Abstract: Disclosed embodiments include apparatuses, systems, and methods for providing a sound indicative of a pressure of a tire relative to a target pressure. A target pressure specifier is configured to specify a target pressure for a tire and generate a target pressure signal indicative of the target pressure. A pressure monitor is configured to receive the target pressure signal, a current pressure signal indicative of a current pressure of the tire, and an indicator of a deliberate change in the current pressure and compare the current pressure signal with the target pressure signal responsive to the indicator. A status signal is generated indicative of a status of the current pressure signal relative to the target pressure signal. An audio generator is configured to receive the status signal and to generate a sound audible outside of the passenger compartment of the vehicle that is indicative of the status signal.

Abstract: Various disclosed embodiments include systems, vehicles, and methods for controlling towing of a vehicle without an electrical connection between a tow vehicle and a towed vehicle. In an illustrative embodiment, a system includes a controller. The controller includes a processor and computer-readable media configured to store computer-executable instructions configured to cause the processor to: receive sensed data indicative of at least one attribute of a tow vehicle without an electrical connection between the tow vehicle and a towed vehicle; and control an attribute of the towed vehicle responsive to the sensed data indicative of a corresponding attribute of the tow vehicle.

Abstract: Various disclosed embodiments include illustrative systems, vehicles, and methods. In an illustrative embodiment, a system includes a sensor configured to generate route information, and a control unit. The control unit includes a processor in signal communication with the sensor and a memory configured to store computer-executable instructions. The computer-executable instructions are configured to cause the processor to receive the generated route information, generate a wheel signal responsive to the received route information indicating a change in wheel engagement status, and output the wheel signal to a disconnect.

Abstract: Systems and methods are provided herein for operating a vehicle in a vehicle yaw mode. In response to initiating vehicle yaw mode, the system engages an open-loop mode, that provides open-loop forward torque to the outer wheels of the vehicle and open-loop backward torque to the inner wheels of the vehicle until a sufficient number of wheels are slipping. In response to determining that a sufficient number of wheels are slipping, engaging a closed-loop mode. While operating in the closed-loop mode, one or both of the wheel rotation and vehicle yaw rate are monitored to adjust the torques provided to the wheels of the vehicle to control the vehicle yaw rate.
