Power domain controller and system, electric vehicle and control method

Abstract

The invention discloses a power domain controller and system, an electric vehicle and a control method. The power domain controller comprises a whole vehicle control module used for determining torque according to the working condition of a whole vehicle; the battery management module is used for monitoring the performance of a battery system in the electric vehicle; the motor management module is used for controlling the speed of the electric vehicle according to the torque determined by the whole vehicle control module; the energy management module is used for managing the energy of the electric vehicle according to the current speed of the electric vehicle and the performance monitoring result of the battery system; and the main control module is used for carrying out driving control on other modules in the power domain controller after receiving the control signal. Due to the fact that the whole vehicle control module, the battery management module, the motor management module, the energy management module and the main control module are integrated in the power domain controller, part of signals can be transmitted in the controller, the real-time performance of the controller is improved, meanwhile, the number of the controller is reduced, and the complexity of the system is reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a power domain controller, a system, an electric vehicle and a control method. Background technique [0002] With the continuous development of the automobile industry, electric vehicles are increasingly favored by people. At present, the controller of electric vehicle usually adopts a distributed controller architecture. Based on the distributed controller architecture, each functional module has its own independent controller. [0003] With the rapid increase of electric vehicle communication data, independent controllers will lead to poor real-time signal transmission, and multiple independent controllers will increase the complexity of the system. SUMMARY OF THE INVENTION [0004] The present invention provides a power domain controller, a system, an electric vehicle and a control method, which are used to solve the problems of poor real-time perform...
