Problems solved by technology

However, the double-sided wheel loading device is prone to inconsistent operation of the two-sided wheels, that is, it is difficult to adjust the balance of the output torque of the two-sided load motor under the same or different speed operating conditions, or it is difficult to adjust the same or different torque operating conditions Speed ​​balancing of double-sided load motors
It is impossible to accurately simulate the running conditions of the whole vehicle under the same working conditions of the wheels on both sides
At the same time, it also leads to differences in the output torque of the wheels on both sides during the test of the automotive powertrain system, thereby increasing the loss of the powertrain system and shortening the test life of the tested powertrain system
Therefore, in the dual-motor cooperative work in the related art, there is a technical problem that it is difficult to coordinate and control the speed and torque of the dual-motors
[0003] For the above problems, no effective solution has been proposed

Abstract

The invention discloses a load motor control method and device, electronic equipment and a computer readable memory. The method comprises the following steps: determining a three-phase current value and a to-be-adjusted parameter of a first load motor; according to the three-phase current value of the first load motor, an actual quadrature-axis current value of the first load motor is obtained by applying Clark transformation and Park transformation; determining a target quadrature-axis current value of the first load motor according to the to-be-adjusted parameter of the first load motor; and adjusting the three-phase current value of the first load motor until the actual quadrature-axis current value is equal to the target quadrature-axis current value. The technical problem that the rotating speed and the torque of the double motors are difficult to coordinate and control in the cooperative work of the double motors in the related technology is solved.
