Title:
FOUR-WHEEL DRIVE ELECTRIC VEHICLE POWER DISTRIBUTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/037651
Kind Code:
A1
Abstract:
A four-wheel drive electric vehicle power distribution method and apparatus. At least two motors are mounted on a four-wheel drive electric vehicle. The method comprises: during the operation of the vehicle, obtaining a required torque of a driver for operating the vehicle and the real-time rotational speeds of the motors; from a loss power meter corresponding to each motor, obtaining the loss power of a corresponding motor when the motor generates different torques under the real-time rotational speed; taking the sum value of the torques as the required torque, randomly selecting one torque from the obtained torques corresponding to each motor for combination, and calculating the sum value of the loss power corresponding to each torque combination; and according to the sum value of the loss power corresponding to each torque combination, determining the torque distribution proportion of the required torque in the at least two motors, so that the sum value of the loss power corresponding to the determined torque distribution proportion meets a preset requirement.
