摘要：
The invention concerns a method and a device for automatically releasing an automatic parking brake at start-up. According to the invention, a transmitted torque estimation threshold value (ECT_threshold) is determined which enables the vehicle movement to be balanced. Then, at start-up a loop for calculating the transmitted torque estimation (ECT) is carried out so long as the calculated value (ECT) does not exceed the threshold value (ECT_threshold). When the threshold is exceeded, an automatic parking brake release command is produced.
