A simulation test system for automobile motor controller

Abstract

The invention provides a simulation testing system for an automobile motor controller. The simulation testing system for the automobile motor controller comprises a testing host, a programmable power supply, a motor controller, a phase voltage acquiring module and a simulation device, wherein the simulation device is connected with the testing host, and is successively connected with the programmable power supply, the motor controller and the phase voltage acquiring module serially to form a closed-loop system; the programmable power supply, the motor controller and the phase voltage acquiring module are successively connected through a high-voltage wire harness; and the simulating device is respectively connected with the programmable power supply, the motor controller and the phase voltage acquiring module through a low-voltage wire harness. By the simulation testing system for the automobile motor controller, closed-loop simulation of the motor controller is realized under the condition that a control plate and a driving plate in the motor controller do not need to be separated, therefore, a closed-loop simulation environment of the motor controller is established in a laboratory environment, the development progress of the motor controller is accelerated, and the function, performance and fault detection of the motor controller can be tested comprehensively.

Description

technical field [0001] The invention relates to the field of closed-loop simulation, in particular to an automobile motor controller simulation test system. Background technique [0002] With the continuous development of hybrid vehicles and pure electric vehicles, new energy vehicles have entered people's lives and become one of the important means of transportation, playing an increasingly important role in people's work and life. The safety and reliability of automobiles must be reliably guaranteed. The motor system is the core component of new energy vehicles, and its reliability and stability directly affect the driver's driving experience. As the control core of the motor system, the motor controller determines the output torque and speed of the motor, and the accuracy and reliability of the motor control must be guaranteed, so the test of the motor controller is very important. Due to cost, operability, convenience, etc., when it is inconvenient to connect a real mo...
