A distributed all-electric drive system and group control method, including: multiple modular electric drive devices and drive controllers; each modular electric drive device includes wheels, wheel sets, wheel drive shafts, motors, and integrated motors Controller; each group of modular electric drive devices is equipped with an integrated motor controller, and all integrated motor controllers are interconnected with the drive controller to realize the reading of the motor working status and the transmission of control signals; the drive controllers send corresponding control signals respectively The signal is sent to each integrated motor controller, and each integrated motor controller drives the motor in the modular electric drive device to work according to the received corresponding control signal, and transmits the signal to the wheel group through the wheel drive shaft, finally driving the wheel to rotate. The invention adopts rule-based multi-motor cooperative control, intelligent group control, etc., adaptively identifies driving conditions, reduces power cycle in the driving process, realizes optimal system efficiency, reduces tire wear, and improves chassis driving safety.
Description
technical field [0001] The invention relates to a distributed all-electric drive system and a group control method, belonging to the technical field of multi-axle heavy-duty special vehicles. Background technique [0002] The all-electric drive system is an important means for multi-axle special vehicles to pursue high power and high economy. [0003] Publication No. CN200910242538.2 invention patent discloses a gasoline-electric four-wheel drive hybrid power system and its control method. The system uses the motor and the engine as independent power sources to drive the front and rear drive wheels of the vehicle respectively, and uses a motor controller Control the work of the motor, the engine controller controls the work of the engine, and use the vehicle controller to coordinate the work of the engine controller and the motor controller. [0004] Publication No. CN201410145972.X invention patent discloses a driving force coordinated control system and control method for...
