Systems and methods to control auxiliary power output voltage using a welding output voltage are disclosed. An example power system includes an engine, a generator to provide electrical power based on mechanical power received from the engine, the electrical power comprising welding-type power and non-welding power, and a controller to control the generator or the engine to increase or decrease a voltage of the non-welding power based on a voltage measurement of the welding-type power.

A method of controlling a vehicle, and which includes wirelessly communicating, via a wireless communication unit, with at least one other vehicle; displaying, via a display, a list of activities that are executable together during a commonly available autonomous driving time period where both the vehicle and the least one other vehicle are operated in an autonomous driving mode; receiving, via a controller, a selection of an activity in the displayed list of activities; and displaying, via the display, an execution screen of the selected activity during the commonly available autonomous driving period.

Provided is a disclosure for a vehicle platform that includes acquiring information, analyzing the information, and controlling the vehicle, as well as sharing the acquired information and infotainment in the vehicle with other vehicles and electronic devices.

A power supply includes: a power converter that converts an input voltage by switching at a switch and supplies an output voltage and an output current to an output terminal connected to a load; a current detector that detects the output current or a current that changes with the output current and outputs a current detection signal whose voltage value changes with the output current; a signal corrector that inputs and corrects the current detection signal and generates and outputs a corrected current detection signal whose voltage value corresponds to the value of the output current; a matching circuit that inputs the corrected current detection signal and outputs to a balanced terminal; and a controller that inputs the corrected current detection signal and a balanced voltage signal generated at the balanced terminal and controls switching operations of the switch to reduce a difference between the two signals.
