A system, method and device for the operation of electrically motorized vehicles that can utilize an electrically motorized wheel to convert a non-motorized wheeled vehicle to an electrically motorized wheeled vehicle. The electrically motorized wheel can include a modular systems package with a motor, power supply, sensor system and control system that is operable to communicate locally and globally via various mobile devices. The control system for a device of an electrically motorized wheel includes an application module operable to execute a control algorithm that manages operation of the device.

This motor driving control apparatus has (A) an inverter unit configured to drive a motor; (B) a separation switch configured to separate a power source from the inverter unit; and (C) a controller configured to instruct the separation switch to separate the power source from the inverter unit and control the inverter unit to perform switching according to a speed and a braking target torque, upon detecting an event that braking should be performed without passing a regenerative current to the power source from the inverter unit. By introducing the separation switch that operates as described above, it becomes possible to perform control so as to consume the power by the motor itself without passing the regenerative current to the power source such as a battery.

In a method of inferring a vehicle state for control of a vehicle component based on the vehicle state inference, the vehicle may include a first electromechanical brake module operably coupled to first wheel-end brakes of a first wheel and a second electromechanical brake module operably coupled to second wheel-end brakes of a second wheel. The method may include receiving an indication of vehicle speed, receiving an indication of vehicle voltage supply to determine whether an event trigger transition is detected based on a change in the vehicle voltage supply, determining a communication state of at least one of the first and second electromechanical brake modules responsive to the event trigger transition being detected, where the communication state is one of a connected state or a disconnected state, and initiating a state inference operation based on the indication of vehicle speed and detection of the event trigger transition.

An electric-powered wheelbarrow in one aspect of the present disclosure includes a motor, a wheel, an electromagnetic brake, a control circuit, a signal-processing circuit, and a drive circuit. The electromagnetic brake includes an electromagnetic coil. The electromagnetic brake (i) applies a braking force to the wheel in response to the electromagnetic coil being de-energized and (ii) releases the braking force from the wheel in response to the electromagnetic coil being energized. The control circuit outputs a first control signal and a second control signal. The signal-processing circuit receives the first and second control signals to thereby output a deactivating signal. The drive circuit receives the deactivating signal and delivers an excitation current to the electromagnetic coil.

A vehicle, such as a rail vehicle, has an electrodynamic braking apparatus with at least one brake resistor. The at least one brake resistor forms a portion of the vehicle body shell that is permanently closed and over which air flows on the exterior, in particular, during travel of the vehicle. In the alternative, the brake resistor is arranged in the immediate vicinity of the permanently closed portion. The brake resistor conducts away heat outwardly to the environment via the permanently closed portion. There is also described a brake resistor for a vehicle, in particular for a rail vehicle, which is configured accordingly.
