ABSTRACT:
A method and a device for automatically releasing an automatic parking brake at start-up. A transmitted torque estimation threshold value is determined that enables the vehicle movement to be balanced. Then, at start-up a loop for calculating the transmitted torque estimation is carried out so long as the calculated value does not exceed the threshold value. When the threshold is exceeded, an automatic parking brake-release command is produced.
