电控发动机ECU 标定系统

为了对汽车发动机电子控制单元的自主研发提供检验支持,开发了一款基于CAN总线通讯的发动机电子控制单元标定系统。标定系统包括标定系统软件、通信模块、待标定发动机电子控制单元和被测发动机4个部分,采用多主结构CAN-bus数据通信方式。实现了上位机的标定表格设计,表格数据的整理,标准协议与自定义协议的转换接口的设计,基于协议的数据传输、在线烧录、采集、控制与诊断等功能。在汽车发动机电喷系统产品上的实际应用表明：该标定系统通用性好,数据处理效率高,适用于不同协议的发动机电子控制单元产品。

Electronic Control Engine ECU Calibration System

To provide testing support for independent research and development of the automotive electronic control unit,an engine ECU calibration system which based on the CAN bus communication was developed.The calibration system includes four parts.That’s a calibration system software,communication module,the engine ECU and the engine that to be calibrated and tested.It uses the CAN-bus as the communication which has the main structure of a higher rate.The main achievement is that design the host computer’s table,collect and process the data,design the conversion interface between the standard protocol and a custom protocol,send data,receive data,load data,upload data,programming,acquisition data,and hardware detection,control functions,etc.EFI products in the practical application of the system showed that the system agreed with good universal property,efficient data processing and it is suitable for various ECU products that use different protocol.
