Vehicle Power Distribution Control Method, Apparatus and System

A vehicle power distribution control apparatus, comprising:

• a road surface recognition module, configured to acquire an image of a road surface on which a vehicle drives currently, and recognize, according to the image of the road surface, the type of the road surface on which the vehicle drives currently;
• a power distribution strategy determining module, configured to start a corresponding terrain mode in an all terrain adaptive mode according to the current type of the road surface, and determine a power distribution strategy corresponding to the current terrain, mode according to a correspondence between terrain modes and preset power distribution strategies, the terrain mode in the all-terrain adaptive mode comprising at least two of a common terrain mode, a snow mode, a mud mode, and a sand mode;
• and
• a power distribution control module, configured to switch a center differential of the vehicle to a corresponding locking mode according to the current power distribution strategy, and distribute torques to front and rear axles of the vehicle according, to a torque distribution curve corresponding to the current power distribution strategy,
• wherein the torque distribution curve is a function curve using a throttle position as a variable and a torque proportion of a driven axle as an output.

A vehicle power distribution control system, comprising:

• a road surface recognition apparatus, an all-terrain controller and a power distribution apparatus, wherein
• the road surface recognition apparatus is configured to acquire an image of a road surface on which a vehicle drives currently, and send the image of the road surface to the all-terrain controller;
• the all-terrain controller is configured to start a corresponding terrain mode in an all-terrain adaptive mode according to the current, type of the road surface, determine a power distribution strategy corresponding to the current terrain mode according to a correspondence between terrain modes and preset power distribution strategies, and send the power distribution strategy to the power distribution apparatus, the terrain mode in the all-terrain adaptive mode comprising at least two of a common terrain mode, a snow mode, a mud mode, and a sand mode;
• and
• the power distribution apparatus is configured to switch a center differential of the vehicle to a corresponding locking mode according to the current power distribution strategy, and distribute torques to front and rear axles of the vehicle according to a torque distribution curve corresponding to the current power distribution strategy,
• wherein the torque distribution curve is a function curve using, a throttle position as a variable and a torque proportion of a driven axle as an output.
