A control system, a switch and a control method for a hybrid vehicle, the vehicle operable in a hybrid mode where a combustion engine and an electric motor can be used, and in an electric mode where only the electric motor can be used. The control system includes a propulsion mode control module configured to control the vehicle to operate in one of the hybrid mode and the electric mode. The propulsion mode control module is further configured to verify that the vehicle has been in an off-state for a predetermined period of time before switching from the hybrid mode to the electric mode.

A method of thermal management for an electrically motorized wheel, the method can include defining a thermally conductive path from at least one component, the at least one component becoming heated during operation of the electrically motorized wheel, providing the path with a thermally conductive material and further defining the path such that the path contacts the at least one component, further defining the path such that the path contacts a hub shell assembly of the electrically motorized wheel thereby conducting heat from the at least one component to the hub shell assembly.

A method for active vibration control of a hybrid electric vehicle may include: selecting a reference angle signal based on position information of a motor or an engine; generating a reference angle based on information of the reference angle signal; setting up a period of fast Fourier transform (FFT) and analyzing the FFT signal; setting up a reference spectrum according to an engine speed and an engine load; extracting a vibration component from each frequency based on information of the reference spectrum; selecting and adding a removal object frequency from the vibration of each frequency and performing inverse FFT; determining a basic amplitude ratio according to the engine speed and the engine load and an adjustable rate according to the engine load; and performing active vibration control of each frequency based on the information of the basic amplitude ratio, the adjustable rate, and the engine torque.

A vehicle includes an engine, a first motor generator that is configured to generate electric power using the power of the engine, an electric storage device that is configured to store the electric power that is generated by the first motor generator, a connection part through which the electric power that has been stored in the electric storage device is supplied to the outside of the vehicle; and an ECU that is configured to start the engine when the SOC of the electric storage device reaches a predetermined starting threshold value. The ECU sets a starting threshold value ON2 that is used when the vehicle is in an undrivable condition and electric power is being supplied to the outside of the vehicle through the connection part to a value smaller than a starting threshold value ON1 that is used when the vehicle is in a drivable condition.

A method of analyzing vehicle parameters to distinguish between whether an unexpected vehicle acceleration is due to an internal fault or external forces. The method uses a magnitude and direction of a change in acceleration for evaluating whether the unexpected acceleration is due to a potential system fault scenario or a potential crash scenario.

A bicycle hub includes a hub axle, a hub body, an electric power generator, a freewheel and an electric unit. The hub body is rotatable around the hub axle. The electric power generator is disposed between the hub axle and the hub body. The electric power generator is configured to generate electric power by a relative rotation of the hub axle and the hub body. The freewheel is configured to support a sprocket. The freewheel is connected to the hub body and is rotatable around the hub axle. The electric component is disposed between the hub axle and the freewheel in a radial direction with respect to the center axis. The electric unit is electrically connected to the electric power generator.

An air cut-off valve module and a control method thereof is provided. The air cut-off valve module has a structure in which valve plates and driving mechanisms thereof are formed as one module, and is mounted in a stack. Thus, components related to the air cut-off valve are constructed as a compact module. Furthermore, a bypass flow path is formed to dilute exhaust gas of the stack, thereby reducing the concentration of hydrogen.

A method and a device are provided for controlling a vehicle to output an assisting power. The method includes: obtaining a friction force between the vehicle and ground; determining a target assisting power of the vehicle according to the friction force; and controlling a motor of the vehicle to output the target assisting power. By technical solutions of the present disclosure, it may enable the vehicle to adapt to different ground and adjust the assisting power outputted by the motor automatically.

A power supply includes a load, an electric power line connected to the load, first and second DC power supplies which supply electric power to the load, an electric power converter connected between the electric power line and the first and the second DC power supplies, and a controller controlling the electric power converter. The first DC power supply serves for a voltage control, while the second DC power supply serves for an electric power control. The controller sets a difference between an electric power requested by the load and target output electric power of the first DC power supply as target output electric power of the second DC power supply, and compensates the target output electric power of the first DC power supply in accordance with a difference between the actual and the target output electric powers of the second DC power supply.

A method and device for controlling a running mode of a hybrid vehicle are provided. The method includes monitoring power consumption of a battery when the hybrid vehicle is driven in an electric vehicle (EV) mode and calculating a threshold value for starting an engine. Then, whether to change the running mode of the hybrid vehicle is determined using the power consumption of the battery and the threshold value for starting the engine.
