Problems solved by technology

For example, the Chinese patent application whose publication number is CN1649345A, the title of the invention is "CAN bus-based pure electric bus communication method", and its application discloses a CAN bus communication method for pure electric buses, which is realized based on a single CAN bus The communication of the pure electric bus uses a single CAN bus to realize the information communication of the motor controller, electronic throttle controller, cab display, ABS controller and power storage battery management system. There have been breakthroughs in communication technology, but there is still a problem that the speed of electronic control signal transmission will be relatively lagging behind due to the rapid development of electric control signals in pure electric buses.

Abstract

The invention relates to a system and a method for communication of a pure electric vehicle based on independent four-wheel drive of double motors, and the communication system comprises a CAN (controller area network) bus, wherein the CAN bus is connected with a whole vehicle controller with a message acceptance filter, a battery management system, a first motor controller, a second motor controller, a first electromagnetic clutch controller, a second electromagnetic clutch controller, a high-pressure controller, a charge controller, a driving recorder, an instrument information display system and a remote dispatching system through CAN bus communication interfaces respectively. The communication system has the benefits of utilizing the bus communication method based on multi-constraint dispatching to realize synchronization control of a power transmission system which mutually connects two lines in parallel, ensuring the real-time property of control, and improving the reliability of the electric vehicle.

Description

Technical field [0001] The invention relates to the field of electric vehicles, in particular to a pure electric vehicle communication system and method based on dual motors and independent four-wheel drive. Background technique [0002] The increasingly prominent problems such as the oil crisis and environmental pollution have made electric vehicles increasingly attract the attention of the society and become the future direction of automobile development. With the strong support of the state, China's electric vehicles have developed rapidly. At present, electric vehicles mostly use a single-motor drive scheme. At the same time, in order to avoid network congestion due to the increase in the amount of bus information, most vehicles adopt the method of increasing the physical number of buses. For example, the Chinese patent application with the publication number CN1649345A, the invention title is "The CAN bus-based pure electric bus communication method", its application disclo...
