| 摘要 |
The present invention relates to a method for a data transmission from an ultrasonic sensor (100) to an electronic control unit (150). Echo information is produced by the sensor in a measuring cycle Mn, Mn+1 etc. Each measuring cycle has a measuring window MFn, MFn+1 etc. Each echo information is transmitted from the sensor to the electronic control unit in a communication window KFn-1, KFn etc. within the following measuring window Mn, Mn+1 etc. The sensor varies the starting instant of the communication window independently so that an interfering signal S(n-1), S(n) etc. varies its temporal position and can be recognized as such. |
