[0081] The second embodiment of the present invention provides a vehicle seat controller load simulation method based on the existing technology, and the specific contents are as follows:

[0082] like Figure 2 As shown in the second embodiment of the present invention, the seat motor is driven to rotate forward by an analog controller, and the method includes the following steps:

[0083] The ECU controller establishes a serial communication connection with the simulation system;

[0084] The user drives the simulated motor components of the simulation system through the ECU controller logic program;

[0085] The simulation system is controlled by serial port commands to output PWM square waves, which are transmitted to the Hall data acquisition terminal of the ECU controller to implement the closed-loop control logic of the motor, thereby verifying whether the ECU's logic for controlling the forward rotation of the motor is normal and simulating the real motion state.

[0086] like Figure 3 As shown, the second embodiment of the present invention is for the ECU to control the heating function logic, the steps are as follows:

[0087] The ECU controller implements the logic for driving the seat heating function and then drives the heating resistor of the simulation system;

[0088] The ECU controller reads the current temperature data output by the simulation system through the serial port;

[0089] The ECU controller uses the PID algorithm to calculate whether the set temperature value is met. If the condition is met, the heating output is stopped; otherwise, the temperature regulation function is continued.

[0092] The ECU controller reads the current wind speed data through the serial port;

[0093] The ECU controller calculates whether the set ventilation level is met through the PID algorithm. If the conditions are met, the ventilation output is stopped, otherwise the ventilation function continues to be output.

[0094] like Figure 5 FIG. 1 is a flowchart for precise seat positioning adjustment in the second embodiment of the present invention, and the steps are as follows:

[0095] The ECU controller implements the motor drive logic for the seat percentage positioning function and outputs it to the simulation system;

This highly matched module collaboration not only faithfully reproduces the operating states of each functional module, but also ensures that test results are closer to actual operating conditions, effectively improving the accuracy and reliability of load simulation and providing strong support for the development and testing of seat controllers.
