Electric automotive motor and monitoring device for controlling system operation course

Abstract

The invention relates to an motor for electric car and a monitoring device for the operating course of its control system, comprising: master control board, RS232-RS485-USB converter and mobile computer, connected in turn in bidirectional circuit form, where the master board is connected through CAN communication network with motor, motor controller and whole car controller in the whole car and collects and packs system protocol monitored data; the RS232-RS485-USB converter transmits data packets to the mobile computer; the mobile computer receives the data packets and unpacks the data packets into the original same data in the master control board and stores and divides them into data files and visualized data for development personnel to make field analysis and error correction or make further research and analysis later. And the invention also has the advantages of low cost, small bulk and easy to operate.

Description

technical field [0001] The invention relates to a debugging device for the performance of an electric vehicle motor and its drive system, in particular, it is a device for monitoring and debugging the running process of the motor and its control system installed inside the electric vehicle. Background technique [0002] As shown in Figure 1, the electric drive control system of an electric vehicle mainly consists of a vehicle controller (also known as a multi-energy controller) 1, a CAN communication network 2, and a controller (inverter) of the motor / integrated starter generator (motor) 3 4 composition. During the operation of the electric vehicle, the vehicle control 1 sends a control command to the motor 3 through the CAN communication network 2 according to the driver's command and the current running state of the vehicle. After receiving the operation command, the motor controller 4 responds to the instruction of the vehicle controller 1 in combination with the current...

Problems solved by technology

But, there is following drawback in such system: 1) system software and hardware are expensive

2) The system is large in size and requires an external power supply (220 / 110V AC), which is very inconvenient to use; 3) Especially since the vehicle manufacturer and the manufacturer of the motor and its controller belong to different manufacturers, for the sake of protecting their respective IPs, both They will not open their respective control data information to each other, so it is difficult to integrate the monitoring system of various vehicle components
