Abstract: Embodiments of this application propose a low-voltage redundant power supply system, including: a high-voltage battery pack, configured to provide a first voltage and including a number of power supply units sequentially connected in series, each of the power supply units being at least one battery in the high-voltage battery pack or an equivalent power supply formed by connecting a number of batteries in series/parallel; and a relay array, with relays in the relay array connected to the power supply units in the high-voltage battery pack based on a specified connection relationship, where in at least one on/off state combination of the relay array, at least one power supply unit in the high-voltage battery pack is reused in a time-division manner to provide a second voltage to supply power to a low-voltage load; and the first voltage is higher than the second voltage.

Abstract: A method for vehicle control includes: determining, based on first status information of a vehicle, that the vehicle satisfies a condition to perform a steering return, where the first status information of the vehicle includes information that an initial turning angle of a turning wheel of the vehicle is greater than a first threshold; determining, based on second status information of the vehicle, that a user has a need to park for a long time, where the second status information includes status change information of the vehicle, and the status change information of the vehicle is used to determine that the user has the need to park for a long time; and performing a steering return process in a first preset time period based on a first function.
