SPEEDOMETER CORRECTION DEVICE |
| 摘要 |
A method of correcting a vehicle speed displayed on a speedometer may include identifying a type of a control module in a vehicle. The method may additionally include determining a speed-related parameter to be revised based on the type of the control module. The method may additionally include receiving a reported vehicle speed and an actual vehicle speed. The method may additionally include determining a proportion between the reported vehicle speed and the actual vehicle speed. The method may additionally include determining a corrected value for the speed-related parameter based on the proportion between the reported vehicle speed and the actual vehicle speed. The method may additionally include detecting an end of a drive cycle. The method may additionally include transferring the corrected value of the speed-related parameter to update the control module after detecting the end of the drive cycle. |

1. A method of correcting a vehicle speed configured to be displayed on a speedometer, the method comprising:
identifying a type of a control module in a vehicle; determining a speed-related parameter to be revised based on the type of the control module; receiving a reported vehicle speed and an actual vehicle speed; determining a proportion between the reported vehicle speed and the actual vehicle speed; determining a corrected value for the speed-related parameter based on the proportion between the reported vehicle speed and the actual vehicle speed; detecting an end of a drive cycle; and transferring the corrected value of the speed-related parameter to update the control module after detecting the end of the drive cycle. |
