2 results about "Direct torque control" patented technology

The application discloses a control system of a distributed drive vehicle and a control method thereof, and comprises a whole vehicle integrated brake controller and a motor controller. The whole vehicle integrated brake controller is used for acquiring vehicle state signals, and the vehicle state signals at least include vehicle speed, wheel speed and motor rotating speed. The motor controller is in communication connection with the whole vehicle integrated brake controller, and the motor controller is integrated with a direct torque control module. The application realizes millisecond-level fast response by sinking the slip rate control to the inside of the motor controller through the direct torque control module, and solves the problems of long control period and slow response of the traditional traction control system.

The application relates to the technical field of engineering vehicle control, and discloses a remote control type high-speed aerial platform truck driving energy management system and a control method. The system comprises a vehicle controller, front / rear axle driving motors, a battery management system and a remote controller. The vehicle controller directly maps a remote control rocker travel into driving or braking demand torque, realizing direct torque control. The system receives allowable charging and discharging currents and voltages of the BMS in real time, converts the currents and voltages into dynamic torque limit values based on the law of conservation of energy, and combines one-dimensional interpolation table lookup of high and low speed gears to correct power. When braking, a two-dimensional mapping model of vehicle speed and braking depth is used to give feedback torque. The application solves the problems of response lag of traditional speed loop control and inaccuracy of high-speed operation, guarantees battery safety, and significantly improves energy recovery efficiency and driving stability.
