The drivetrain system disclosed uses a controlled slip between an electric motor and one or more driven wheels to unify propulsion and regenerative braking. A planetary gearset (or similar two degrees-of-freedom gearing) connects the motor to the wheel, with a friction brake applied to one gear element to modulate torque. The motor is actively regulated to maintain a small constant speed offset (slip) relative to the wheel's rotation. This slip allows the motor to either drive or brake the wheel depending on its direction, with the transmitted torque being inherently proportional to the applied force on the friction brake. In multi-wheel configurations, a single motor drives multiple wheels via respective gearsets, inherently apportioning torque between wheels like a limited-slip differential without separate differential hardware. The result is a highly efficient, bidirectional drive and braking system that recovers energy, eliminates coasting drag, and uses existing brake components for torque control.
