Abstract: Disclosed are a bus current control method, a device, a system and a storage medium. The method includes: obtaining a data set including a motor speed corresponding to a current time point, an actual current and an actual torque; determining a limit current at the current time point according to the motor speed; in response to the limit current being less than the actual current, determining a deviation value at the current time point according to the limit current and the actual current; determining a target requested torque based on the deviation value and the actual torque; and determining the bus current according to the target requested torque.

Abstract: A controlling apparatus and method for an electric drive transmission used in a dual-motor electric vehicle are disclosed, wherein when the second motor is in the zero torque state, the synchronizer is shifted to a neutral position, the second motor the required torque being kept to be zero; after shifted to the neutral position, if the target gear position is the neutral position, gearshifting is completed, an if the target gear position is not the neutral position, speed control to the second motor is conducted to adjust its speed towards a target speed; once the second motor is adjusted to the target speed, the second motor is subjected to zero torque control, the second motor the required torque being zero; once the second motor comes into a zero torque state, the synchronizer is shifted to a target gear position, the required torque of the second motor being kept to be zero; once the synchronizer is located in the target gear position, the required torque of the second motor changes towards a target valu
