  "textContent": "The present invention provides a vehicle control method for controlling a capacitance ripple and a torque ripple of a vehicle drive system, wherein the vehicle drive system comprises a first DC-DC convertor. The vehicle control method comprises utilizing a first three-phase inverter circuit of a motor control device of the vehicle drive system as a first switching circuit of the first DC-DC convertor; utilizing a first three-phase winding of a motor of the vehicle drive system as a first three-phase inductor of the first DC-DC convertor; utilizing a pulse width modulation controller of the vehicle drive system for modulating a first three-phase current outputted by the first switching circuit to generate a first three-phase carrier wave; and setting a first phase difference of each phase of the first three-phase carrier wave for controlling the capacitance ripple and the torque ripple.",
