Embodiment Construction

[0027] Attached below Figure 1-3 The present invention will be described in further detail.

[0028] As shown in Figure 1, the USB-CAN card 2 communicates with the compressor controller 3 through the CAN bus and communicates with the LabVIEW program 1 of the host computer through the USB cable.

[0029] After the compressor controller 3 is powered on and initialized, parameter calibration can be performed.

[0030] The LabVIEW program 1 sends a connection instruction to the compressor controller 3 according to the CCP (CAN Calibration Protocol) protocol, and waits for the compressor controller 3 to return an instruction of successful connection, thereby establishing communication.

[0031] The connection instruction needs to be packaged by the CAN bus data package module 11 of the LabVIEW program, and then sent to the USB-CAN card 2 by the USB line driver module 13.

[0032] The CAN bus driving module 33 receives instructions from the USB-CAN card 2, and the compressor controller CAN ...

Abstract

The invention discloses an automobile air-conditioner compressor controller calibration system and method. The calibration system includes a host computer LabVIEW program, a USB-CAN card and a compressor controller; the LabVIEW program is based on a CCP ( CAN calibration protocol), transfers parameters that need to be calibrated to the compressor controller through the USB-CAN card and monitors the real-time operation condition of the compressor controller; the calibration parameters include two types of parameters; and the first type of parameters are directly written to a flash storage area, the second type of parameters are first written to an RAM area, and at the same time, the real-time operation condition of the compressor controller is monitored, and finally, a group of optimal parameter values is written into the flash storage area of the compressor controller. Based on the calibration system, the development efficiency of the compressor controller can be greatly improved.

Description

Technical field [0001] The invention relates to a calibration system and a calibration method for an automobile air conditioner compressor controller, in particular to a system and method for calibrating an automobile air conditioner compressor controller. Background technique [0002] In the 21st century, environmental pollution has become more and more prominent, which has triggered changes in the automotive industry. Automobiles are transformed from traditional fuel vehicles to electric vehicles, and electric vehicle related industries are also facing more severe tests. As an important link that affects car comfort, automobile air conditioning needs to optimize the parameters of its compressor controller. [0003] Due to the connection between the on-board controller and the components, and there are individual differences between the components of the same model, it is necessary to adjust the parameters of the controller for different compressors under the premise that the com...
