Title:
CONTROLLER OF ELECTRIC MOTOR CONTROL MODULE, CONTROL METHOD FOR ELECTRIC MOTOR, AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/082904
Kind Code:
A1
Abstract:
A controller (1011, 3011) of an electric motor control module, a control method for an electric motor, and a related device. An input end of the controller (1011, 3011) is connected to a rotation speed measurement apparatus, such that the controller (1011, 3011) can receive a rotation speed signal of an electric motor from the rotation speed measurement apparatus; a communication end of the controller (1011, 3011) is connected to a first communication bus (103, 303) and a slave controller (1041, 3041), such that the controller (103, 303) can directly acquire a vehicle speed of a vehicle from the first communication bus (103, 303), and can directly communicate with the slave controller (1041, 3041); and an output end of the controller (1011, 3011) is connected to a control end of an inverter circuit (1012, 3012) in the electric motor control module, such that the controller (1011, 3011) can output a control signal to the inverter circuit (1012, 3012). When the vehicle speed of the vehicle and a rotation speed signal of a first electric motor (1013, 3013) meet a preset condition, the controller (1011, 3011) controls the inverter circuit (1012, 3012) in the electric motor control module to adjust a current, which is to be outputted to the first electric motor (1013, 3013), and controls the slave controller (101, 3041) to adjust a current, which is to be outputted to a second electric motor (103, 3043) by an inverter circuit (1042, 3042), which is connected to the slave controller (101, 3041). Therefore, trackslip can be rapidly controlled, and the control precision and control efficiency are high.
