Abstract

Gearbox control method for controlling gear selection of a gearbox (203) based on topographic route information, comprising steps: - Receiving (S1) topographic route information; - Storing (S2) data sets based on the topographic route information in a memory; - Checking (S3) the memory (202b) for a memory overflow, performing the following steps if a memory overflow is detected: - Mark (S4) a data record as invalid if a memory overflow has been detected; - Control (S5) the gear selection of the transmission based on the data records in memory (202b) which are not marked as invalid.
