Test simulation instrument of automotive air conditioning controller

Abstract

The invention provides a test simulation instrument of an automotive air conditioning controller. The test simulation instrument is used for connecting a computer and the conditioning controller respectively and carrying out simulation test operation. The test simulation instrument of the automotive air conditioning controller at least comprises a universal serial bus (USB) communication module, a K-line communication module, a controller area network (CAN) bus communication module, an analogue-digital (AD) sampling module, a digital signal input module, an analogue output simulation module, a digital output simulation module, an air conditioning power supply module and a central processing module. The test simulation instrument is used for monitoring various input signal states, and simulating and outputting an external signal which is required by the controller simultaneously; the test simulation instrument is connected with the computer through a USB interface and displays a current state of each piece of equipment and a simulation output signal on the computer intuitively, so operation is simple, large-scale production test and product development application can be carried out conveniently, and high intelligence is further realized; and the test simulation instrument is characterized by high accuracy, convenient operation, high efficiency, cost saving and the like, so research and development capacity and production capacity are improved remarkably.

Description

technical field [0001] The invention relates to the field of automobile electronics, in particular to an automobile air-conditioning controller testing simulator applied to automobile air-conditioning control systems and parts.
