[0021] like Figure 1-2 As shown, the AMT gearbox and shift actuator control system of a new energy mining vehicle of this embodiment collects signals from the external environment and the system itself, and transmits motor power and realizes shift control according to a pre-designed shift program and shift logic (existing transmission technology, which will not be described in detail). The specific structure includes a TCU main control module, a sensor unit, an execution unit, an MCU and a power supply module. The TCU main control module is the core module of the AMT gearbox, which is responsible for command processing, gear drive, SCI communication, etc. The execution unit executes the instructions of the TCU main control module to realize the final shift operation. During operation, after receiving the driver's throttle signal command, the TCU main control module of the mechanical AMT gearbox combines the current motor speed signal, vehicle speed signal, and gear position signal to simulate and adjust the shift in time to reduce the shift time.

[0022] The sensor unit is used to collect signals, and the collected signals include motor speed, vehicle speed, gear data, and gear displacement signals, and the signals are transmitted to the TCU main control module through the sensor signal processing module. The sensor signal processing module is connected to the TCU main control module. The sensor unit includes a speed sensor, a speed sensor, a displacement sensor and a gear sensor. The speed sensor is used to obtain the motor speed signal, the speed sensor is used to obtain the vehicle speed signal, the displacement sensor is used to obtain the gear displacement signal, and the gear sensor is used to obtain the gear signal. The speed sensor and the gear sensor are electromagnetic sensors, and the design method of the displacement sensor is consistent with that of the inductive sensor. When the position of the terminal actuator changes, the inductive quantity of the displacement sensor will also change.

[0023] The execution unit includes a gear solenoid valve and a speed sensing solenoid valve. The TCU main control module drives the gear solenoid valve and the speed sensing solenoid valve through the solenoid valve driving module, thereby adjusting the gear shift execution motor.

[0024] MCU is a motor controller. The MCU transmits signals to the TCU main control module via the CAN bus. The MCU transmits throttle, motor speed, and brake signals to the TCU main control module via the CAN bus. The TCU main control module gives instructions to the MCU via the CAN bus.

[0025] The power supply module supplies power to the TCU main control module. In this embodiment, the TCU main control module supports efficient instruction set retrieval and efficient addressing mode, and supports enhanced Boolean bit operations. When the time is triggered, it automatically matches the source data with the CPU instruction cycle to complete data transmission in the entire address space.

[0026] like Figure 3 As shown in Figure 2, when the operating point is in the constant torque region, if the AMT gear is downgraded ( Figure 3 The motor changes its operating point to a position where the motor efficiency is higher, and the motor power increases accordingly; when its operating point is in the constant power zone, the AMT gear is lowered ( Figure 3 The motor also changes its operating point to a position where the motor efficiency is higher.

[0027] The utility model can collect signals such as motor speed, vehicle speed, gear data, gear displacement, etc. through the sensor unit, which is convenient for the TCU main control module to analyze, and adjust the gear shift execution motor through the gear solenoid valve and speed sensing solenoid valve of the execution unit. The throttle, motor speed, and brake signals can be transmitted to the TCU main control module through the MCU, which is convenient for data processing and is beneficial to improving the motor efficiency and improving the economy of the whole vehicle.
