The invention relates to the related technical field of vehicles. The invention discloses a vehicle gear lifting control method and device, electronic equipment and a storage medium. The method comprises the following steps: controlling a first motor and a second motor for driving rear wheels to work; responding to a gear switching request of the first motor, performing internal resistance compensation on the torque of the first motor based on the internal resistance of the first motor and the internal resistance of the second motor when the gear switching request is responded, calculating the transfer torque of the second motor at the current moment according to the compensation torque, and transferring the transfer torque of the second motor from the first motor to the second motor; after the torque is transferred, a synchronizer of the first motor is controlled to be in a neutral gear; calculating a target rotating speed of the first motor, and controlling the rotating speed of the first motor to reach the target rotating speed; and after the rotating speed of the first motor reaches the target rotating speed, a synchronizer of the first motor is controlled to be engaged in the target gear. According to the torque transfer, the internal resistance compensation is performed based on the first motor internal resistance and the second motor internal resistance, so that the transfer torque can be accurately calculated.
