The invention discloses a power domain controller and a motor torque control method, and the power domain controller comprises a BMS function module which is used for generating power battery information based on vehicle information; the charging and discharging module is composed of an OBC function module and a DCDC function module and outputs battery charging and discharging information; the VCU function module is used for generating demand torque information based on the vehicle information and the related information of the power battery; and the MCU function module is used for generating a torque control signal based on the vehicle information and the required torque information. According to the invention, through the control of each functional module in the integrated power domain, the complexity is reduced, the problems of low error-tolerant rate and low accuracy of the CAN bus caused by factors such as increase of the load rate of the CAN bus and electromagnetic interference in the transmission process of the CAN bus are effectively avoided, and the transmission efficiency of the CAN bus is improved. The accuracy of related signals of torque calculation or torque control in the transmission process is greatly improved, and then the safety of the whole vehicle is improved.
