Method for distributing power of an electrical drive train of a working machine, control device, computer program product and working machine

Abstract

A method for distributing power of an electrical drive train of a working machine, wherein the drive train has a traction drive and an auxiliary drive, the method including determining an actual power allocation for the traction drive and an actual power allocation for the auxiliary drive and determining a current working state of the working machine. The method further includes specifying a target power allocation to the traction drive and a target power allocation to the auxiliary drive based on the determined current working state of the working machine and adjusting the actual power allocation for the traction drive to the target power allocation for the traction drive, and adjusting the actual power allocation for the auxiliary drive to the target power allocation for the auxiliary drive.

1 : A method for distributing power of an electrical drive train of a working machine, wherein the drive train has a traction drive and an auxiliary drive, the method comprising:
 determining an actual power allocation for the traction drive and an actual power allocation for the auxiliary drive,   determining a current working state of the working machine;   specifying a target power allocation to the traction drive and a target power allocation to the auxiliary drive based on the determined current working state of the working machine; and   adjusting the actual power allocation for the traction drive to the target power allocation for the traction drive, and adjusting the actual power allocation for the auxiliary drive to the target power allocation for the auxiliary drive.   
     
     
         2 : The method as claimed in  claim 1 , comprising specifying, if a loading state or an unloading state is determined as the current working state, the target power allocation to the traction drive to be lower than the target power allocation to the auxiliary drive. 
     
     
         3 : The method as claimed in  claim 1 , comprising specifying, if a traveling state is determined as the current working state, the target power allocation to the traction drive to be higher than the target power allocation to the auxiliary drive. 
     
     
         4 : The method as claimed in  claim 1 , comprising specifying, if a Y cycle is determined as the current working state, when the working machine is reset, the target power allocation to the traction drive to be higher than the target power allocation to the auxiliary drive; and
 subsequently after the working machine is turned, specifying the target power allocation to the traction drive to be lower than the target power allocation to the auxiliary drive.   
     
     
         5 : A control device for a working machine, wherein the control device is configured to be connected to the electrical drive train of the working machine, and wherein the control device is configured to carry out the method as claimed in  claim 1 . 
     
     
         6 : A computer program product comprising commands which, when executed, performs the method as claimed in  claim 1 . 
     
     
         7 : A working machine, comprising:
 the control device as claimed in  claim 5 ; and   an electrical drive train,   wherein the drive train has a traction drive and an auxiliary drive, and   wherein the control device is connected to the drive train.
