An intelligent somatic full-balance electric vehicle comprises two wheels (11, 12) of a same size and a motor (4) disposed between the two wheels (11, 12), the two wheels (11, 12) being coaxially connected to the motor (4) through an axle (3); the intelligent somatic full-balance electric vehicle further comprises a control system (10) and a power supply (9); both the control system (10) and the power supply (9) are disposed inside a housing of the vehicle body and located above the wheels, or between the two wheels (11, 12); or one of the control system (10) and the power supply (9) is located between the two wheels (11, 12), and the other is located above the wheels; vertical columns (6) are separately disposed at two ends of the axle (3), and the vertical columns (6) are separately provided with pedals (5) on external sides of the wheels. Because the two coaxial wheels (11, 12) are used, the electric vehicle can implement full balance like a bicycle, and in addition, has unique advantages of a monocycle, namely, having a small size and being easy to carry.

In some embodiments, a rotorcraft includes a fuselage having a rotor hub assembly protruding therefrom that is rotatable relative thereto. A generator having an armature is mechanically coupled to the rotor hub assembly such that the armature is rotatable in response to rotation of the rotor hub assembly. A braking unit is in selective electrical communication with the generator. The braking unit is adapted to apply an electrical resistance to rotation of the armature, thereby reducing a rotational speed of the rotor hub assembly.

A power supply system for a house is constructed such that electrical power that will need to be supplied from an electric vehicle to a house in a delay time taking a power transmission delay into account is predicted, a prediction data of the predicted electrical power is communicated to a power supply control device via a house communication device and a vehicle communication device, and electrical power that corresponds to the prediction data is supplied to a power-supplying coil by the power supply control device.

A ride-on zero-turn work machine has two drive control levers longitudinally pivotable for locomotive and steering control, and laterally tiltable inboard and outboard for parking brake control. Two brake control linkages are each connected between one of the levers and one of the parking brakes. Each linkage features a rotatable bell crank, a brake connection link running from the bell crank to the parking brake, and a lever connection link having one end coupled to the bell crank, and another coupled to drive control lever through a ball joint that, in an inboard position of the lever, and throughout a full longitudinal pivot range thereof, lies on the lever's pivot axis, with no motive effect on the bell crank or parking brake. Laterally outward tilting of the lever moves the ball joint off axis, in a manner driving rotation of the bell crank, and thereby actuating the parking brake.

A brake system, a controller and a method for detecting a loss of ground connection in a controller for a vehicle are disclosed. The controller has a first unit and a second unit, and the first and/or the second unit comprise(s) a microcontroller. The first unit is connected to a first ground terminal by a first ground line and the second unit is connected to a second ground terminal by a second ground line. The controller comprises a single ground loss detection resistor arranged in the first or in the second ground line. The current in the first and/or the second ground line is ascertained and evaluated by the microcontroller in order to determine whether a loss of the connection has occurred at one of the ground terminals.

A vehicle includes an electric machine configured to recharge a battery through regenerative braking, an electric heater configured to heat a powertrain lubricating oil, and a controller. The controller, in response to a temperature of the powertrain lubricating oil being less than a threshold, directs regenerative braking power to the electric heater.
