Method and apparatus for estimating an expected reception quality
First Claim
1. A method for estimating an expected reception quality in a reception time interval for a Car to X communication by a memory, the method comprising:
- depositing at least one empirically determined variable in the memory for reception patterns of data packets in a first time interval, wherein the at least one empirically determined variable specifies or provides data to determine a probability that a data packet or a number (n) of data packets will be received successfully in a subsequent second time interval;
determining a reception pattern for a first time interval before the reception time interval and the associated probability for the reception time interval is read out of the memory; and
generating a change in functionality of a driver assistance function based on the probability.

Abstract
A method and an apparatus for estimating an expected reception quality in an interval of time for car-to-X communication including a receiving device for acquiring data packets and a memory, wherein the memory stores at least one empirically determined variable for reception patterns of data packets in a first interval of time, which variable indicates or can be used to determine how high the probability is of a data packet or n data packets being successfully received in a subsequent, second interval of time, wherein the apparatus is designed so that the reception pattern is determined for a first interval of time before the interval of time and the associated probability for the interval of time is read from the memory, wherein a warning message is generated and/or a transmission parameter and/or a functionality of a driver assistance function is/are changed on the basis of the probability.

6. A device for estimating a quality of reception to be expected in a reception time interval for a Car to X communication, the device comprising:
-
a receiving device for acquiring data packets and a memory, wherein at least one empirically determined variable is deposited in the memory for reception patterns of data packets in a first time interval, wherein the at least one empirically determined variable specifies or provides data to determine a probability that a data packet or a number (n) of data packets will be received successfully in a subsequent second time interval, wherein the device is designed so that, for the first time interval before the reception time interval, the reception pattern is determined and the associated probability for the reception time interval is read out of the memory, wherein a warning message is generated based on the determined probability and a functionality of a driver assistance function is changed based on the determined probability. - View Dependent Claims (7, 8, 9, 10)
