Example Embodiment

[0020] The ASAP standard is a set of matching calibration specifications. The ASAP standard is mainly composed of three parts, namely ASAP1, ASAP2, and ASAP3. As the interface standard between the application layer and the control device, the ASAP1 part defines the physical and logical connection between the application system and the ECU, and realizes the unified management of the upper and lower communication of the matching calibration system. XCP is a kind of ASAP1a. The ASAP2 part realizes unified management of all calibration data, monitoring data, interface information, etc., standard and standardized description of ECU functions, interfaces and calibration information, and the ASAP description file (*.a21 file) generated according to this standard is used as calibration The database of the system. The ASAP2 standard uses the ASAP2 meta-language A2ML (ASAP2Meta Language), and uses structured text to describe monitoring and calibration parameters and their interface informat...

Abstract

The invention provides an automobile electronic control unit marking system and a method on the basis of ASAP standard, relating to the field of automobile electronic control technique. The ASAP standard is adopted to describe the marking/monitoring data property; the map file of an ASAP editing module on the basis of ECU is used for generating an ASAP database which is used for describing the marking/monitoring data property; an upper host machine configures the working environment according to the ASAP database, uses a CAN bus to carry out communication with the ECU by an XCP protocol, emits a marking control command, receives the ECU monitoring data, carries out the display, storage and analysis of the monitoring data, and realizes the marking and the monitoring to ECU parameters. The method of the invention overcomes the defects that the existing marking method has nonstandard data management, is difficult to be adapted to the changes of the ECU types and the communication interfaces of the ECU and has poor generalization, and improves the generalization and the adaptability of the marking system, thus improving the efficiency of the marking operation.

Description

technical field [0001] The present invention relates to computer and automatic control technology, in particular to the field of automotive electronics technology, and mainly relates to a calibration technology of an automotive electronic control unit (ECU, Electronic Control Unit) based on the ASAP standard. Background technique [0002] It is an extremely complicated process for automotive electronic control units to develop from a prototype to a product. The working process of the engine and even the entire vehicle is a very complex dynamic, nonlinear, hybrid time-varying system with corresponding lags. Their performance depends on a large number of mechanical dynamics and thermodynamic parameters, and it is difficult to accurately express it with an accurate mathematical model. Come out, in order to make the vehicle achieve the best overall performance, the control parameters of the electronic control system must be calibrated accurately, so that it can run according to ...
