Abstract

The invention provides a motor controller and control method thereof. The motor controller comprises a control module, a drive module, a measurement module and a motor controller PCB, wherein: the measurement module measures the operating parameters of the motor, the temperature of the motor controller PCB, and the basic temperature and operating parameters of the driving module, and provides theoperating parameters of the motor, the temperature of the motor controller PCB, and the basic temperature and operating parameters of the driving module to the control module. The control module calculates the surface temperature and the node temperature of the driving module according to the operating parameters of the motor, the temperature of the motor controller PCB, and the basic temperatureand operating parameters of the driving module. The control module controls the closing and opening of the driving module according to the surface temperature and the node temperature of the driving module. The motor controller and control method thereof realize that the software dynamically adjusts the motor current threshold to realize the protection of the system, and flexible.

Description

technical field [0001] The invention relates to the technical field of automobile power control, in particular to a motor controller and a control method thereof. Background technique [0002] Brushless DC motors (BLDC) are more and more widely used in automatic transmission control systems (TCU) due to their small size, excellent torque characteristics and mature control system solutions, including clutches, gear selection actuators and oil pumps. Such systems are favored by various vehicle manufacturers and transmission suppliers. [0003] The over-current and over-temperature faults of the drive circuit of the brushless DC motor are one of the main reasons affecting the performance of the automatic transmission control unit (TCU). Stability and safety, and the key to its protection lies in the accurate acquisition of the junction temperature and surface temperature of devices such as MOSFETs in the drive module. In the prior art, the protection of the drive circuit is at...
