  • Method for maintaining a desired braking torque
    Patent number: 7249810
    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.
    Type: Grant
    Filed: January 19, 2002
    Date of Patent: July 31, 2007
    Assignee: ZF Friedrichshafen AG
    Inventors: Bernhard Grupp, Bernhard Reisch, Frank Sauter, Peter Schmidtner
  • Method for increasing brake efficiency
    Patent number: 6910989
    Abstract: Within the framework of the method for increasing brake efficiency of a vehicle with a hydrodynamic retarder, the rotational speed of the motor is increased by command for downshifting, in such a manner, that the increased cooling fluid circulation flow, due to the higher rotational speed of the motor speed, the necessary retarder braking power is made available, whereby a downshift command is issued, if this is necessary due to the actual retarder braking power.

  • Method for performing the function "constant speed on the gradient"
    Publication number: 20040070272
    Abstract: When performing the function of “constant speed on the gradient”, the necessary braking power is determined as a function of the vehicle's loading.
