A method is provided for operating a drive train comprising an internal combustion engine or an electric machine as a primary drive and an electric machine as a secondary drive, wherein the electric machine is detachably coupled, together with an inverter and controller, on one of the vehicle axles. The electric machine and at least one switchable element is actuated in order to minimize drag losses of the electric machine and to provide a defined connection time for the electric machine. The electric machine is stationary and decoupled during a first speed range. The electric machine is actuated at a preset speed during a second speed range, where a defined connection time is not possible if the electric machine were stationary. The electric machine is coupled to the axle and rotates at the vehicle speed in the third range, when losses while coupled are lower than if uncoupled.

Method and control for a drive system having four-wheel drive

A vehicle having a longitudinal engine and permanent rear axle drive is proposed, which vehicle has an internal combustion engine and an electric machine, a transfer gearbox distributing drive torques as required to two drive axles, the transfer gearbox having three shafts, a main shaft serving as a drive shaft of the rear axle, a secondary shaft serving as a drive shaft for the front axle, and an intermediate shaft applying a torque, a shifting unit being installed between the reduction gear-box and the power summation gearbox.
