Description

technical field [0001] The invention relates to an intelligent test system and a test method for an automobile motor controller, in particular to an intelligent test system and a test method for an electric vehicle motor controller. Background technique [0002] Electric vehicles are widely considered to be one of the main ways to solve problems such as vehicle exhaust pollution and oil energy shortages. With the rapid development of electric vehicles, the product performance, consistency and reliability requirements of its core components are becoming more and more important . [0003] The motor controller is the control unit of the electric vehicle powertrain, and its product performance will directly affect the performance index of the whole vehicle. At present, a set of electric drive bench test system is generally used for the off-line detection of the motor controller. The system structure is complex, bulky, inconvenient to test, there are many human test factors, and...
