Abstract

The invention discloses an automatic controller CAN (Controller Area Network) interface function test system and a test analysis method. The test system comprises a calibration unit, a CAN receiving and transmitting unit, a calibration control unit, a CAN receiving and transmitting control unit, a main test control unit and a main test control interface. The automatic CAN interface function test system provided by the invention can rapidly accomplish automatic test on hundreds of controllers, and obtain final the results of the test by a single operator in one to two hours, and has low requirements on the technical level of the operator. In addition, the test system can change an interface unit according to changes of the hardware of the calibration unit and the CAN receiving and transmitting unit, so that the test on different devices can be realized. The test method of the test system is comprehensive. a CAN bus can be divided into different test sections to be tested, and the system response situation also can be tested at the same time.

Description

technical field [0001] The invention relates to the technical field of hardware-in-the-loop (HIL) testing of automotive electronic controllers, and more specifically relates to a controller CAN interface function automatic testing system and a testing analysis method. Background technique [0002] With the rapid development of automobile technology and electronic technology, modern automobiles have widely adopted electronic control technology to improve automobile power, economy, safety, comfort, and reduce exhaust pollution. Electronic control technology is an important trend and symbol of the development of modern automobile technology, from engine fuel injection, ignition control, intake control, emission control, fault self-diagnosis to chassis transmission system, steering and braking system, as well as body and auxiliary devices etc. have generally adopted electronic control technology, among which the application of automotive electronic controllers is the most common...
