The invention relates to the technical field of agricultural machinery, and discloses an electric tractor, a motor control device and method thereof and a whole vehicle control system. The electric tractor comprises an operation motor and a walking motor which are driven independently, and the motor control device comprises a whole vehicle controller which is used for obtaining and generating a first control instruction and a second control instruction aiming at speed adjustment of the operation motor and the walking motor according to a sensor signal associated with the current operation working condition; the operation motor controller is configured to receive and respond to the first control instruction to adjust the rotating speed of an operation motor; and the walking motor controller is configured to adjust the rotating speed of the walking motor in response to the second control instruction. According to the electric tractor, power decoupling and independent speed control of the walking motor and the operation motor of the electric tractor are achieved, the walking speed and the operation speed can be matched, and therefore the tractor can adapt to different kinds of soil to conduct efficient and high-quality operation.

    本发明涉及农机技术领域,公开了一种电动拖拉机及其电机控制装置、方法和整车控制系统。其中,该电动拖拉机包括各自独立驱动的作业电机和行走电机,且所述电机控制装置包括:整车控制器,用于获取并根据关联于当前作业工况的传感器信号,分别生成针对作业电机和行走电机的速度调节的第一控制指令和第二控制指令;作业电机控制器,被配置为接收并响应于所述第一控制指令调节作业电机的转速;以及行走电机控制器,被配置为响应于所述第二控制指令,调节所述行走电机的转速。本发明实现了电动拖拉机的行走电机和作业电机的动力解耦及单独速度控制,且可以进行行走速度和作业速度的匹配,从而使得拖拉机能够适应不同的土壤进行高效且高质量的作业。
