to date signal qk if at instant t4 the drive slip control 70 once again recognizes that the drive wheels are spinning it decreases the quantity of fuel to be injected the drive slip control 70 starts at the up to date control signal qka of the drive slip control 70 or at the up to date signal qk at instant t4 the drive slip control 70 again determines the up to date signal qk if there is a priority signal ps from the automatic transmission control 60 the automatic transmission control 60 determines the quantity of fuel to be injected if there is no priority signal ps from the automatic transmission control 60 the signal qka from the drive slip control 70 the driver request qkfb or the signal qkg from the automatic transmission control 60 determines the quantity of fuel qk to be injected if it is recognized that the drive wheels are spinning an advantage of the system according to the present invention is that when the priority signal ps is present the drive slip control 70 has an effect until the control signal qka from the drive slip control 70 is greater than the control signal qkg from the automatic transmission control 60 if this condition is satisfied the drive slip control 70 is switched off i e it is set in its initial state and does not.
