The invention discloses a starting control method and device of a vehicle, electronic equipment and a storage medium. In response to an accelerator pedal operation of a driver, determining a target demand torque and a target starting rotating speed when a transmission input shaft and a clutch are synchronized, and obtaining a current input shaft rotating speed of a transmission and a current clutch rotating speed; determining a target input shaft rotating speed based on the target starting rotating speed and the current clutch rotating speed; determining a current closed-loop control torque based on the current input shaft rotating speed and the target input shaft rotating speed, and determining a target closed-loop control torque based on the target demand torque and the current closed-loop control torque; and controlling the operation mode of the motor to be a rotating speed mode, and controlling the motor to perform closed-loop control on the next input shaft rotating speed of the transmission input shaft based on the target closed-loop control torque until the current clutch rotating speed and the current input shaft rotating speed reach the target starting rotating speed, so that the vehicle realizes linear starting acceleration, and the vehicle starting acceleration smoothness is improved.
