ESP32在基于模型设计中的应用研究

Research on the Application of ESP32 in Model-Based Design

汽车中新增对发动机的外部转速请求功能,在前期原型开发中采用手机端blinker+ESP32+MCP2515方案,识别按钮输入并计算转速请求状态信号和需求转速信号,核心计算逻辑采用Simulink基于模型的设计,最后通过CAN发送。发动机控制器打断原有目标怠速计算路径,加入新增CAN信号计算逻辑,实车测试,数据表现符合功能定义,基于模型的设计展现了强大效用。

The external speed request function for the engine is added to the car.In the early prototype development,the mobile phone blinker+ESP32+MCP2515 is used to identify the button input and calculate the speed request status signal and the required speed signal.The core calculation logic adopts Simulink model-based design and transmit through CAN finally.The engine controller interrupts the original target idle speed calculation path,adds the new CAN signal calculation logic,and the actual vehicle test shows that the data performance conforms to the function definition,and the model-based design shows a powerful effect.
