A control system 110C for a vehicle 100 winch 110 having an electric reluctance winch motor 116, the amount of current drawn by which is controlled to maintain a substantially constant winch line 114 tension. The value of tension may be selected by a user, via a user input device (figure 3). Controller 110C may limit line tension to an upper value. It may also account for changes in diameter of the winch drum as cable is wound, controlling drum speed accordingly. The system may set a maximum rate at which cable can be wound, and said rate may be chosen by a user (figure 3). The system may apply a brake torque to the winch drum, which may effect regenerative braking, and may also limit the rate of increase of torque. Power supply potential may be between 110V and 5kV. The vehicle may be electric or hybrid, may have an inverter unit, an electric traction motor, and a charge storage module, or battery.
