Abstract
A vehicle control device includes motors that respectively drive front and rear, left and right wheels independently, wheel speed sensors that detect rotation speeds of the respective wheels, motor rotation speed sensors that detect rotation speeds of the motors corresponding to the respective wheels, a slip determination module that sets, as a base rotation speed, a lowest rotation speed, and performs slip determination on each wheel on the basis of the base rotation speed and the rotation speeds of the motors, a rotation speed control module that performs torque down, and calculates requested torques of the motors from redistributed torques, and a redistribution control module that redistributes a torque down amount of the slipping wheel to a non-slipping wheel to calculate the redistributed torques.
