Embodiment 1

[0039] Embodiment 1: see figure 1 , figure 2 As shown, the calibration method of the electric luggage system provided in this embodiment includes two parts: initialization and formal calibration.

[0040] The electric trunk controller generally includes the main control chip MCU, input and output circuits, and the FLASH inside the main control chip to save the program. The calibration of the electric trunk is mainly in the automobile production line or in the automobile 4S shop during the automobile production process. For car maintenance, the calibration equipment is different according to the car itself, but generally also includes a processor, software that stores the relevant content in the calibrated car electric trunk controller, through the calibration equipment and the car electric trunk The controller communicates to calibrate the software and hardware of the car electric trunk controller, usually through the CAN bus of the car to complete the communication between ...

Abstract

The invention discloses a method for calibrating a power-driven suitcase, comprising the following steps of initialization and formal calibration, wherein each calibration order is required to read in the formal calibration; each order is conducted sequentially, and a system exits from a calibration state if a flow chart sequence is not complied; and if the calibration is required to conduct again, calibration orders are required to retransmit so as to start a calibration process. The method has the advantages that communication between CAN (controller area network) calibration equipment and a controller of a power-driven suitcase is utilized to calibrate each parameter value in the process of running the power-driven suitcase system, thus saving the self-cost of the controller. CAN communication tools are utilized to calibrate directly, thus reducing the development time of a CCP (CAN calibration protocol) communication protocol; and the own memory FLASH of a master control chip of a system is used to reduce the system cost.

Description

technical field [0001] The invention relates to the field of control of electric trunks of automobiles, in particular to a calibration method for electric trunks. Background technique [0002] The electric trunk of a car means that the trunk can be opened and closed electrically, and some cars also have a remote control function. Under normal circumstances, there is a door closing button in the trunk door, which can be closed by itself without human intervention; if you want to open the trunk, you only need to press the open button in the car, and the trunk will open by itself. Automobiles with electric trunks are very popular among consumers due to the convenience of opening. During the production of automobiles, calibration of the electric trunk is required. [0003] In the common calibration method, the CCP calibration communication standard is used. The CCP communication is a standard based on CAN. This method has the following problems: [0004] 1. Calibration equip...
