  • Patent number: 11318925
    Abstract: A vehicle power distribution control method, apparatus and system are provided. The method includes: acquiring an image of a road surface on which a vehicle drives currently, and recognizing, according to the image of the road surface, the type of the road surface on which the vehicle drives currently; starting a corresponding terrain mode in an all-terrain adaptive mode according to the current type of the road surface; determining a power distribution strategy corresponding to the current terrain mode according to a correspondence between terrain modes and preset power distribution strategies; and switching a center differential of the vehicle to a corresponding locking mode according to the current power distribution strategy, and distributing, in the locking mode, torques to front and rear axles of the vehicle according to a torque distribution curve corresponding to the current power distribution strategy.

  • Patent number: 11247683
    Abstract: Disclosed is a bidirectional transmission control system for a vehicle. A road surface recognition apparatus collects an image of a road surface on which a vehicle drives currently, and forwards, after recognizing the type of the road surface on which the vehicle drives currently according to the image of the road surface, a corresponding first terrain mode request signal to an all-terrain controller through a signal transfer apparatus, so as to start a corresponding terrain mode in an all-terrain adaptive mode. In addition, the all-terrain controller forwards execution information about the terrain mode to the road surface recognition apparatus through the signal transfer apparatus, so as to implement state feedback of the terrain mode currently executed. The inconsistency of information transmission rates between an all-terrain control system of a vehicle and an input system can be coordinated, thereby aiding in real-time switching of various terrain modes.

  • Patent number: 11085384
    Abstract: Related are a method and an apparatus for protecting a clutch in a vehicle driving process. The method comprises: acquiring a current oil temperature of a space where the clutch is located and judging whether the current oil temperature is within a set temperature interval or not; in a case where the current oil temperature is within the set temperature interval, detecting whether a current wheel speed difference between front shaft and rear shaft reaches to a set wheel speed difference threshold or not; and in a case where the current wheel speed difference between the front shaft and rear shaft reaches to the set wheel speed difference threshold, triggering a first protective mode that is preset to protect the clutch; and in a case where the current oil temperature is higher than the set temperature interval, triggering a second protective mode that is preset to protect the clutch.

  • Patent number: 11022052
    Abstract: A vehicle power output control method, apparatus and system are provided. The method includes: collecting an image of a road surface on which a vehicle drives currently, and recognizing, according to the image of the road surface, the type of the road surface on which the vehicle drives currently; starting, according to the current type of the road surface, a terrain mode corresponding to an all-terrain adaptive mode; determining, in the terrain mode, a power output strategy corresponding to the current terrain mode; and adjusting an output torque of an engine according to a power output curve corresponding to the current power output strategy, the power output curve being a function curve using a stepping depth of an accelerator pedal as a variable and the output torque of the engine as an output. The method facilitates outputting an adaptive power by an engine when a vehicle drives on different road surfaces.
