Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing:

[0021] figure 1 It is the composition structure and connection schematic diagram of the automatic test device for automobile body control function of the present invention. The automatic test device is composed of a host computer, a signal conditioning board, a load box, and a tested controller; the host computer is directly connected to the tested controller through a CAN interface and a LIN interface; the output interface of the host computer is connected to the tested controller through a signal conditioning board. The input terminal of the controller is connected, and the drive output of the controller under test is connected to the load box on the one hand, and connected to the input port of the upper computer through the signal conditioning board on the other hand.

[0022] The vehicle body controller as the object under test usually has a CAN interface and (or) a LI...

Abstract

The invention provides an automobile body control function automatic test apparatus and a method thereof, mainly solving problems that a hand-operated test has large time consumption, low efficiency and poor repeatability and special control logics and time sequences can not be tested. The apparatus is composed of a host computer, a signal conditioning plate, a tested controller and a load box. The host computer is connected with the signal conditioning plate through an output interface of the host computer. An output signal is processed by the signal conditioning plate and is sent to the tested controller. A CAN (Controller Area Network) interface and an LIN (Local Interconnect Network) interface of the host computer connect with the tested controller, and send and receive CAN and LIN bus information needed by the test controller. A driving output of the tested controller connects with the load box, and sends a driving signal generated by connection to an input interface of the host computer after processing of the signal by the signal conditioning plate. The apparatus in the invention has the characteristics of clear structure, low cost, and reliable performance, and can carry out a comprehensive automatic test on a control function of the controller so as to eliminate potential safety hazard possibly brought by logic and sequential errors.

Description

technical field [0001] The invention belongs to the technical field of automobile electronic control, and in particular relates to an automatic test technology for automobile body control functions. Background technique [0002] In order to increase the safety and comfort of the car, many car bodies are equipped with one or more controllers to control the exterior lights, interior lights, wipers, central door locks, electric windows, rearview mirrors, etc. Load, this type of controller is usually called a body controller, which is characterized by many input signals, many driving loads, and complex control functions (including control logic and timing), so in the development process of the body controller, a large part of the work It is a test of control logic and timing. The development of body controllers in our country is still in its infancy, and the existing methods are all based on manual testing of experimental benches. Due to the complexity of the control function ...
