Technical Field

[0001] The present invention belongs to the technical field of actuator calibration, and in particular relates to a self-learning calibrator, a learning method and a use method. Background Art

[0002] An electric turbocharger is an engine component that combines traditional turbocharging technology with electric drive technology. It uses an electric motor to assist or fully drive the turbocharger rotor, thereby optimizing engine performance. It is widely used in family cars and trucks.

[0003] The actuator is a key component for achieving precise control of the electric turbocharger, and the calibration of the actuator is an important part of ensuring system performance.

[0004] Currently, actuators are typically calibrated using an OBD device. The process for using existing OBD devices is as follows: the user enters a calibration command through the user interface. The main control unit receives the command and sends a calibration message to the actuator via the communication module and the OBD interface. The actuator then returns a status message, which is displayed on the user interface. Existing OBD devices require manual input of the calibration command each time they are used, making them inconvenient.

[0005] In view of this, the present invention proposes a self-learning calibrator, a learning method and a use method. Summary of the Invention

[0008] Furthermore, the first communication interface and the second communication interface both use CAN communication.

[0009] In a second aspect, embodiments of the present application further provide a learning method for the self-learning calibrator as described in the above aspects, the learning method comprising the following specific steps: When the button unit includes a first button, and the indicator unit includes a first indicator light corresponding to the first button: Long press the first button, the first indicator light flashes red, and the self-learning calibrator enters the learning state; Inputting a calibration command through a user interface on the calibration device, and the calibration device sending a calibration command message; The self-learning calibrator receives a calibration command message sent by the calibration device through the second communication interface, stores the calibration command message in the memory, and forwards the calibration command message to the actuator through the first communication interface; The executor receives and executes the calibration command message, and generates a feedback status message containing status feedback information, and sends the feedback status message to the self-learning calibrator through the first communication interface. The self-learning calibrator stores the feedback status message in the memory and forwards the feedback status message to the calibration device through the second communication interface.

[0010] Furthermore, when the first button is long pressed, the first indicator light flashes red, indicating that the self-learning calibrator enters the learning state, further comprising: The first communication interface is connected to the actuator, and the second communication interface is connected to the calibration device.
