Abstract:
A wheel drive module comprises wheel (R), speed modulation gearbox (G), first electric motor (M1), and second electric motor (M2). First and second electric motors (M1, M2) jointly drive wheel (R) about wheel axis (A) by the speed modulation gearbox (G) and steer said wheel about steering axis (L). Wheel drive module comprises first motor electronics (10) for controlling first electric motor (M1) and second motor electronics (20) for controlling second electric motor (M2) and central electronics (30) connected to first and second motor electronics (10, 20), allowing a signal transfer. Wheel drive module comprises control logic for controlling first and second electric motors (M1, M2), which logic is provided by first and second motor electronics (10, 20), central electronics (30), application electronics (40) connected to the central electronics (30), allowing a signal transfer, or jointly by the central electronics (30) and the first and second motor electronics (10, 20).
