Full-automatic function test method and device for new energy automobile controller

Abstract

The invention discloses a full-automatic function test method and device for a new energy automobile controller. The method comprises steps of S1, controlling the collected information of a to-be-tested controller for recognition, and recognizing the type output of the to-be-tested controller; S2, according to the identified type of the to-be-tested controller, controlling the to-be-tested controller to be connected with a matched test tool in a pre-constructed test tool database so as to use a matched test tool to realize automatic connection of interfaces required when the to-be-tested controller is tested; and S3, according to the identified type of the to-be-tested controller, controlling a matched test program in the pre-constructed test program database to execute a required functiontest on the to-be-tested controller; the device comprises a type automatic identification module, a tool automatic calling module and a function test automatic execution module. The method has advantages of being simple to implement, high in intelligent degree and test efficiency, low in test cost, capable of being suitable for batch test and the like.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle testing, in particular to a fully automatic function testing method and device for a new energy vehicle controller. Background technique [0002] As the core control unit of new energy vehicles, the electric drive control system directly affects the reliability, safety and comfort performance indicators of the entire new energy vehicle, while the controller is the "brain" of the entire electric drive control unit. Whether the function of each unit circuit is normal or not is directly related to the normal driving of the new energy vehicle and the personal safety of the passengers. Therefore, after the assembly of the new energy vehicle controller is completed, electrical function testing is required to judge the drive unit of the controller. , power management, control unit and other electrical functions are normal, energy vehicles have a series of advantages such as energy saving and e...

Problems solved by technology

[0003] In the existing technology, the functional test (FCT, Functional CircuitTest) of the controller in the new energy vehicle is usually carried out by manual control after building a simple test platform, that is, the test connection of the controller to be tested is performed manually, and then the manual test is performed after the connection is completed. Execute various functional tests. If other controllers need to be tested after one test is completed, it needs to be manually disassembled and then reconnected to other controllers. The above-mentioned manual testing method has low test efficiency, high labor costs and is prone to errors, resulting in product quality. Problems, especially when it is necessary to perform batch testing, repeated manual disassembly is required, the entire testing cycle is long, and it is difficult to meet the testing requirements with high real-time requirements

Compared with ordinary vehicles, the electromagnetic environment of new energy vehicles is more complex and harsh, and it is more difficult to test new energy vehicles. The traditional test methods for controllers in ordinary vehicles cannot be directly applied to the control of new energy vehicles. In the test of the controller, it is urgent to provide an automatic test method for the controller in the new energy vehicle, so as to be applicable to the controller of the new energy vehicle to realize the automatic test
