Embodiment 1
[0024] combine figure 1 As shown, a new energy-saving electric loader drive control system,
[0025] The joystick 13 is connected to the vehicle controller VCU3, and the vehicle controller VCU3 is electrically connected to the motor controller I4, the motor controller II10, and the power battery controller BMS2; the vehicle controller VCU is connected to the motor controller I, motor controller II, The vehicle CAN bus communication is adopted between the joystick and the power battery controller BMS; the power CAN bus communication is adopted between the vehicle controller VCU and the motor controller Ⅰ and motor controller Ⅱ; the bus communication mode is adopted, and the transmission efficiency is high, and the system Quick response, accurate data, easy wiring;
[0026] The motor controller Ⅰ4 controls and connects the dual output shaft travel motor 5, the dual output shaft travel motor 5 has front and rear dual output power ports, and the front side output shaft of the dua...
Embodiment 2
[0031] On the basis of the first embodiment above, the control method of a novel energy-saving electric loader drive control system is as follows:
[0032] The vehicle controller VCU requests torque and speed requirements from the motor controller I and motor controller II, and the vehicle controller VCU requests power-on and power-off requirements from the power battery controller BMS;
[0033] The front and rear side output shafts of the dual-output-shaft traveling motor are in the form of front-rear coaxial structure, and the motor controller I of the dual-output-shaft traveling motor is connected to a high-voltage electrical connection; the power battery controller BMS provides the motor control system according to the instructions sent by the vehicle controller VCU. The required current and voltage requirements of the device I, the dual-output shaft walking motor directly drives the front and rear wheels to rotate through the front and rear transmission shafts.
