AI Technical Summary
Technical Problem
Existing vehicle access control systems suffer from low ranging accuracy and unreliable results due to interference factors.
Method used
By setting multiple UWB anchor points on both sides of the vehicle, interference factor error is calculated and eliminated during ranging calculation. The position and distance of the UWB tag are calculated using the Heron formula to determine the interference factor error, thereby improving the accuracy and reliability of ranging.
Benefits of technology
It effectively eliminates interference factors that cause errors in ranging results, improving the ranging accuracy and reliability of the vehicle access control system.
