Abstract: The present disclosure relates to the field of vehicle technology and provides an energy recovery control method, a system, and a vehicle. The method is applied in a vehicle, and the vehicle comprises a drive motor and a battery electrically connected to the drive motor; a first energy recovery torque curve with respect to the drive motor is pre-configured in the vehicle, and the first energy recovery torque curve is used to indicate a correspondence relationship between vehicle speed and energy recovery torque of the drive motor. The present disclosure performs reduction on a first energy recovery torque curve by means of utilizing a reduction ratio, allowing energy recovery in accordance with a relatively low torque strength when a usable charge power of the battery is unable to satisfy a preset power requirement corresponding to the first energy recovery torque curve.

Abstract: A method and a device for controlling vehicle charging, a program, a medium, and a vehicle is provided. The method by acquiring a current connection state of a telematics box in the vehicle and the server when a charging gun of a vehicle is determined in a connection state; and recording a first duration of the offline state when the current connection state is determined in an offline state, and controlling the vehicle charging according to the first duration. In this way, when it is determined that the current connection state is in the offline state, the vehicle charging can be controlled according to the duration of the offline state, which can effectively avoid the problem of charging failure due to network connection failure during the reservation charging process, the reliability of vehicle reservation charging is improved, and thus the vehicle user experience is effectively improved.

Abstract: A method and a device for controlling mode switching of a hybrid electric vehicle, and a vehicle is provided, and belongs to the field of hybrid electric vehicles. The method includes: performing, if the drive state information indicates that a current drive mode of the hybrid electric vehicle is a forward mode of a non-hybrid drive and in a case that a current speed reaches a speed limit, a pre-gear operation when a transmission gear of the hybrid electric vehicle is a neutral gear, to switch the transmission gear from the neutral gear to a second gear. The technical solution provided by the embodiments of the present disclosure can make the hybrid electric vehicle unable to switch to the hybrid drive mode due to the limitation of the ability of synchronizer on gear shifting when driving at a high speed.
