Title:
制動作用の増大方法
Document Type and Number:
Japanese Patent JP2004513827
Kind Code:
A
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.
