The invention relates to a drive system for a vehicle with function for signalling operation. This drive system comprises an electric motor (3, 3', 3'') and a motor electronics (2, 2', 2''), the motor electronics (2, 2', 2'') comprising a power part (5) and a control means (4). The control means (4) outputs at least one pulse-width modulated control signal (7) to the power part (5), by means of which signal switch means of the power part (5) are actuated in such a way that the electric motor (3, 3', 3'') is controllable by means of energy drawn from an energy supply. The pulse-width modulated control signal (7) has a basic frequency (fg). This basic frequency (fg) of the pulse-width modulated control signal (7) is set to generate an audible signal greater than 150Hz and less than 3kHz. The invention also relates to a corresponding axle drive module and a corresponding vehicle.
