Method and system for testing electronic parking brake controller

Abstract

The invention discloses an electronic parking brake controller testing method and system, and the method comprises the steps: building a logic control model which comprises a plurality of model operation parameters based on the logic state of a whole vehicle; logic association is carried out on different model operation parameters, and the operation state of the vehicle is simulated; one model operation parameter is changed, so that other model operation parameters are synchronously changed, and the model operation state is updated; the model operation state is sent to an EPB controller for function testing; wherein the function test comprises at least one of a basic function test, a fault injection test and a basic diagnosis function test; receiving and analyzing test feedback information of the EPB controller, and displaying the test feedback information; wherein the signal transmission with the EPB controller is realized through a CAN (Controller Area Network) bus. According to the invention, the logic state simulation and model establishment of the whole vehicle are realized in the upper computer, the dependence on simulation hardware is small, and the test cost is low; meanwhile, testing functions are complete, operation is easy and convenient, and testing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of vehicle braking, in particular to a testing method and system for an electronic parking brake controller. Background technique [0002] Electronic parking brake (EPB) is a system that uses electronic control to replace the traditional driver to operate the mechanical structure for parking. Its core is to receive signals, make logical judgments and send out The controller of the command; EPB controller software directly affects the function, performance and reliability of the system. It is very important to build a controller test environment, conduct a large number of tests, and realize convenient and efficient testing. [0003] However, most of the test systems in the prior art do not consider the fault injection test and basic diagnostic test, or the simulation of the test environment of the whole vehicle relies heavily on real-time simulation cabinets such as dSPACE, which are expensive and take up a l...

[0003] However, most of the test systems in the prior art do not consider the fault injection test and basic diagnostic test, or the simulation of the vehicle test environment is very dependent on real-time simulation cabinets such as dSPACE, which are expensive and occupy a large space, resulting in inconvenient testing. The cost of testing is also high
