Abstract: To address the issue of poor positioning accuracy of the existing general calibration data in the multi-parameter bluetooth key system, an improvement is made to the positioning and calibration scheme and a calculation method for general calibration data of automotive bluetooth keys based on multi-parameter optimization fusion is proposed, which optimizes the flexibility of the calibration process, improves the unlocking and locking performance of the general calibration data in the bluetooth key system and enhances the stability of the unlocking and locking distances of uncalibrated models. The experimental results show that based on the multi-parameter optimization fusion method, the standard deviation of the left unlocking distance decreases from 3.78 m to 2.80 m, the average unlocking distances in the front and rear directions are increased by 63% and 19% respectively, the average locking distances in the three directions are reduced by 28%, 10% and 21% respectively, and to varying degrees, the phenomena of unlocking delay and long-distance unlocking and locking are resolved, effectively enhancing the user experience of uncalibrated models
