A mobility includes a storage vessel, a power train configured to generate power using liquid hydrogen stored in the storage vessel, and a control device configured to downwardly adjust a target operating pressure of the storage vessel at a time of entering a refueling preparation mode, compare a supply pressure of the liquid hydrogen supplied to the power train with a target hydrogen supply pressure according to the target operating pressure, and limit the power of the power train in response to the supply pressure of the liquid hydrogen being less than the target hydrogen supply pressure.

A driving force control system for a hybrid vehicle is provided to reduce a shock resulting from switching a travelling direction between the forward direction and the backward direction. The control system is applied to a hybrid vehicle in which an operating mode can be selected at least from a series mode and a series parallel mode. A travelling direction of the vehicle is switched by a shifting device between forward direction and backward direction. A controller is configured to maintain the previous operating mode after switching the travelling direction of the vehicle by the shifting device.

An electric vehicle control system and a control method, an electric vehicle power-on method, an electric vehicle power-off method, and an electric vehicle charging method are disclosed in this application. The control system includes a domain control unit controlling an electric vehicle, a current sampling unit sampling the current of a power battery and a motor of the electric vehicle and sending sampling signals to the domain control unit, and electrical device, driven by the power battery, sampling the current flowing through it and sending the sampling signals to the domain control unit. The domain control unit, according to the sampling signals sent by the electrical device and the current sampling unit, manages the power battery and controls a motor driver module and the electrical device. The structure of the control system and the control policy are simplified and the power-on and power-off time is shortened.

A powertrain controller for an electric vehicle (EV) includes a compressor controller configured to regulate three-phases of electrical current supplied by a vehicle battery of the EV or an electric motor of the EV to an electrically-actuated compressor; and a load bank controller configured to regulate a fourth-phase of electrical current provided by the vehicle battery or the electric motor of the EV to a resistive load bank, such that the compressor controller and the load bank controller are integrated into a common control system.

A vehicle which a predetermined mode of the vehicle can be selected by a user. The vehicle including an electric power supply, a socket, an input device, and an electronic control unit. The input device is configured to receive, from the user, a selection indication to select an external supply mode. The external supply mode is a mode corresponding to a case where a position of the electrical device is outside the vehicle. The electrical device is configured to receive electric power from the electric power supply via the socket. The electronic control unit is configured to control the vehicle such that traveling of the vehicle is in a suppressed state when the external supply mode is selected by receiving the selection indication.
