Abstract

The embodiment of the invention discloses an electric vehicle power assembly central controller. The electric vehicle power assembly central controller comprises a central processing unit, a power supply unit, a signal acquisition unit, an output unit and a communication unit. The power supply unit is connected with a power supply interface of the central processing unit, the signal acquisition unit is connected with an input interface of the central processing unit, the output unit is connected with an output interface of the central processing unit, and the communication unit is connected with a communication interface of the central processing unit. A battery pack can be monitored, a traction motor and a transmission can be controlled, the cost of the controller is reduced, wire harnesses are simplified, the weight is reduced, the space requirement is lowered, the system structure is simplified, and the reliability of a system is improved. The electric vehicle power assembly central controller has variables needed by a BMS, a GCU and a TCU and variables needed by vehicle control, and the signal quantity is large; torque needed by a driver is effectively evaluated, and the optimum output torque of the motor is determined under the conditions of factors such as the battery electricity quantity, the road condition and the vehicle condition.

Description

technical field [0001] The invention relates to the technical field of electric vehicle electronic control, in particular to an electric vehicle power assembly central controller. Background technique [0002] In today's society, due to the increasing dependence of human travel on motor vehicles, the environment continues to deteriorate. Electric vehicles have been greatly promoted and applied all over the world, alleviating the pressure of environmental pollution. [0003] At present, the country divides the main technology of electric vehicles into three major parts: battery, motor, and electronic control, which are the three essential elements of electric vehicles. If a transmission is used, a transmission controller must also be added. The battery has a battery management system (BMS), the traction motor is controlled by a motor controller (MCU), the transmission is controlled by a transmission controller (TCU), and the vehicle controller (VCU). The three controllers, ...
