ABSTRACT:
A stepped braking system is used as a function of the required braking torque in this method for maintaining a desired braking torque in a vehicle equipped with stepped and infinitely-variable permanent braking systems whereby simultaneous activation of the stepped and infinitely-variable braking systems occurs in such manner that the sum of the participations of the different systems provides the required braking torque at any time.
