A method and a circuit for controlling electric power delivered to an electric motor are disclosed. A forward control signal is transmitted when a forward command is received while a forward latch is not set. The forward latch is set and the forward control signal is stopped when a power level of the motor exceeds a threshold while the forward command is received. The forward latch is reset and a reverse control signal is transmitted when a reverse command is received. The reverse and forward control signals are not transmitted when no command is received. A reverse latch is optionally set when the power level exceeds the threshold while the reverse command is received. A winch connected to the motor has a cable wound thereon in a forward direction of the motor and unwound therefrom in a reverse direction of the motor, as controlled by the circuit.

The present disclosure discloses a vehicle, a winch for the vehicle, and a warning control device for the winch of the vehicle. The warning control device includes: a warning component; and a warning control board, including: a load detector, connected to the motor through a current sensor, and configured to detect load condition of the motor by collecting measured working current of the motor; a processor, connected to the load detector and the warning controller respectively, and configured to output a warning control signal to the warning controller according to the load condition of the motor; and a warning controller, connected to the warning component and the processor respectively, and configured to receive the warning control signal and to control the warning component to produce a warning based on the warning control signal.

Disclosed are a winch, a rope guide, and a transmission device having a clutch function. The winch includes a base seat, a reel, a rope guide, a transmission assembly, and a motor. The reel is rotatably provided to the base seat. The rope guide is provided to the base seat. The transmission assembly is connected with the rope guide. The motor is connected with the reel to drive the reel to rotate, and the motor drives the rope guide through the transmission assembly. In the winch according to embodiments of the present disclosure, the rope guide is an active rope guide, bringing about a good rope guiding effect. Moreover, the reel and the rope guide are driven by the same motor, which reduces the number of components and parts, simplifies the structure and control, and lowers costs.
