Description
Technical Field
The invention relates to the technical field of automobile manufacturing, in particular to an automatic calibration system and method for a whole automobile function module.
Background
Currently, as each large OEM (Original Equipment Manufacturer), colloquially called "agent", becomes more and more aggressive in preempting market share, competition for vehicle functional configurations has become one of the focus points each contending for market share, such as cruise function, and so on. On the other hand, due to the gradual increase of oil consumption regulations, various engine oil-saving functions have gradually become the functions of main engine factory standard allocation, such as start and stop, gear shifting prompt and the like.
The parameters of the functional modules such as collision fuel cut, starter control, cruise, start and stop are provided with a common characteristic, namely the main control parameters of the modules are derived from the following sources: direct input from the customer or indirect input from the customer through a series of transitions. In other words, the parameter setting of the whole vehicle function module has stronger one-to-one correspondence with the input of the client. In addition, the parameters of the functional modules are numerous, the customer input is different, and almost every new project needs to be set one by one according to the parameters input by the customer. Specifically, a conventional method for calibrating a vehicle function module may refer to fig. 1.
However, the conventional method for calibrating the functional module of the whole vehicle mainly has the following problems:
1) the input parameters mainly depend on the experience of engineers, and the matching quality of the parameters and the functional modules is not high. The method is characterized in that a complete and mature function parameter input form which can be filled by a client is absent, under the condition that the client does not know the strategy of an EMS (engine management system), the EMS does not know which input parameters are needed, and the input cannot be actively given, so that the matching of a plurality of project function modules lacks necessary input, and the matching of the function modules depends on the personal experience of an engineer, therefore, the matching quality of the modules is difficult to guarantee, and especially, the engineer with insufficient experience is easy to make mistakes.
2) The EMS system depends on a plurality of modules input by clients and a plurality of matching quantities, the client inputs are different, the traditional matching means is basically that the documents are defined according to the function control logics and the client input parameters are compared and calibrated one by one, once the client input is changed, the whole process needs to be repeated, and the efficiency is extremely low.
Aiming at the defects of the calibration method of the whole vehicle functional module in the prior art, the technical personnel in the field are always searching for a solution.
