    Abstract: A method of obtaining battery capacity, includes: acquiring a voltage-capacity curve of a battery; performing differentiation on the voltage-capacity curve to obtain a voltage differential-capacity curve; identifying wave crests in the voltage differential-capacity curve; calculating heights and widths between each wave crest and the adjacent wave trough on the left and the right;
    calculating a determination index p according to the heights and the widths; determining a voltage knee point in the voltage-capacity curve according to a wave crest with a minimum determination index; acquiring a reference capacity value corresponding to the voltage knee point in the voltage-capacity curve; after the battery reaches a full-charge state, acquiring charging electric energy of the battery for charging from the voltage knee point to the full-charge state; and obtaining a capacity of the battery based on a sum of the reference capacity value and the charging electric energy.

    Abstract: A vehicle steering system and a vehicle are provided. The vehicle steering system includes a steering shaft and a steering transmission shaft. The steering shaft or the steering transmission shaft includes a first shaft section and a second shaft section. A clutch mechanism is arranged between the first shaft section and the second shaft section. In an engaging state, a transmission connection is established between the first shaft section and the second shaft section, and in this case, a controller determines that the vehicle enters a driving mode. In a disengaging state, the transmission connection between the first shaft section and the second shaft section is disconnected, and in this case, the controller determines that the vehicle enters a game mode.
