Along with the development of automotive electronics, the application of electronic installation seems more and more important in the car, such as engine, steering gear, clamping device and speed change gear, the control corresponding unit is arranged all separately, has improved the intelligent and security of automobile greatly.Along with the application of these control modules, new requirement has also been proposed for the performance verification and the functional test of each function and control module, for example accuracy, accuracy, validity and anti-interference etc.
At present, test for Auto Electronic Controlled System (control unit of engine, automatic anti-lock and driving antiskid control unit, electric power steering control module, automatic shift control unit etc.) mainly is at the corresponding off-line test device of certain Control System Design, tests on the test-bed that can roughly simulate the real vehicle working environment.But bench test is a kind of artificial simulation test, compares with real actual road test, has defectives such as test variable is few, test data is inaccurate.Practical effect is often unsatisfactory.Therefore for the performance test of Auto Electronic Controlled System, a large amount of real roads real train tests must be carried out, the performance of each control module could be tested exactly.
In addition, existing proving installation is generally just to each control module (ECU) test separately, and performance such as have intercommunication mutually to control module, influence each other such as can't test at problem.Because the traffic of a plurality of control modules in Full Vehicle System is very big, there is the equal mutually factor of a part of control content of a lot of data sharings and certain between them, for example control unit of engine and driving antiskid control unit all can be controlled throttle opening, therefore engine, automatic anti-lock and drive anti-skidding, electric power steering and four control modules such as fluid drive all need vehicle speed signal etc. just propose the necessity that many control modules are tested in the integrated performance testing device of same multiple-unit.And many control modules are when testing simultaneously, have that the data acquisition amount is big, test variable is many, a problem such as the big and wiring complexity of communication arbitration amount between each control module, have brought a difficult problem for the real vehicle road test.
Summary of the invention
The purpose of this utility model is the variety of problems that exists in the above test in order to solve, and provides a kind of based on the bus vehicle mounted on-line performance proving installation of CAN.
Of the present utility model based on the bus vehicle mounted on-line performance proving installation of CAN, comprise the automotive engine control unit, automatic anti-lock and driving antiskid control unit, the electric power steering control module, the automatic shift control unit, the CAN bus, USB-to-CAN equipment and have display and the computing machine of keyboard, the automotive engine control unit, automatic anti-lock and driving antiskid control unit, the electric power steering control module, the automatic shift control unit links to each other with the CAN bus respectively with USB-to-CAN equipment, and computing machine links to each other with the output terminal of USB-to-CAN equipment.
The beneficial effect of this device is:
1.CAN bus (Controller Area Network Bus) is a kind of serial data communication bus that can realize exchanges data between numerous controllers and the testing tool, adopt the CAN bus to avoid a large amount of complicated lines between control module, can realize the networking of measurement, control procedure, significantly reduce hardware and have characteristics such as versatility, real-time and extensibility, solved the restriction of traditional test device.
2. the transmission medium owing to the CAN bus is the twisted-pair feeder of band shielding line, its traffic rate height, and have strong anti-electromagnetic interference capability, not only be convenient to computing machine to obtain corresponding information from bus rapidly, and can in varying environment and weather, use.
3. utilize computing machine to realize real vehicle, real-time synchronism detection to a plurality of control modules by software, test data is accurate, the efficient height.
4, whole device is easy to carry, can use on different road conditions, and cost is low, and has high reliability.
