Abstract: This application provides example circuit modules and example electronic devices comprising the circuit module. One example circuit module includes a power input terminal, a power output terminal, a first switching transistor, a second switching transistor, a comparison unit, a boost unit, an energy storage unit, and a direct current conversion unit, where the first switching transistor is turned on and the second switching transistor is cut off when a source voltage input by the power input terminal to the comparison unit is greater than the preset threshold, or the first switching transistor is cut off and the second switching transistor is turned on when a source voltage input by the power input terminal to the comparison unit is less than or equal to the preset threshold.

Abstract: This application provides an automated parking method, apparatus, and system, and is related to the automated driving field. According to the solution provided in this application, an initial driving path and a bypass path can be planned for a vehicle. Therefore, the vehicle does not need to plan a driving path, and further, a large quantity of high-precision sensors do not need to be disposed in the vehicle, thereby effectively reducing costs of the vehicle. In addition, compared with that in a manner in which a vehicle plans a path while performing detection, in the solution provided in this application, a road traffic status in an entire parking domain can be determined, and further, a global initial driving path can be planned for the vehicle, thereby effectively improving path planning efficiency. In addition, a bypass path may be further planned and delivered in advance when an obstacle is detected.
