The invention discloses a vehicle starting control method and device, equipment and a storage medium. The method comprises the following steps: acquiring the operation condition and vehicle information of a vehicle; determining a starting mode of the vehicle, a corresponding starting demand torque and a combined oil pressure change rate of a clutch of the vehicle based on the operation condition; under the condition that the starting mode is double-power-source combined starting, first required torque of an engine of the vehicle and second required torque of a driving motor of the vehicle are determined on the basis of the starting required torque; determining a first torque change rate of the engine and a second torque change rate of the driving motor based on a target impact degree and the vehicle information; and a control unit that performs torque control of the engine on the basis of the first demand torque and the first torque change rate, performs torque control of the drive motor on the basis of the second demand torque and the second torque change rate, and performs engagement oil pressure control of the clutch on the basis of the engagement oil pressure change rate.
