Patent ID: 7434893

Claim:
A device for controlling or regulating total auxiliary brake torque in a motor vehicle, wherein said device comprises: transmission components ( 2 , 3 , 5 , 7 , 9 ) coupled to an engine ( 1 ) and at least two drive wheels ( 8 ); at least one first auxiliary brake ( 4 ) and at least one second auxiliary brake ( 6 ) that is different from the first, the second auxiliary brake ( 6 ) being a retarder ( 6 ); and a control system ( 10 , 17 ) for controlling the first and second auxiliary brakes and in which information on characteristics of the respective auxiliary brakes ( 4 , 6 ) and at least one predefined limit value for maximally permitted auxiliary brake torque are stored, the control system ( 10 , 17 ) being configured so that, if one of (1) the predefined limit value is exceeded and (2) a request is made for a brake force from the auxiliary brakes ( 4 , 6 ) to be moderated, the control system ( 10 , 17 ) effects an adjustment to the magnitude of braking torque imposed by the retarder ( 6 ).
