Problems solved by technology

The main disadvantage of this technical solution is that it is only valid for simple configuration, and the complete functions and hardware and software configuration list of the body control system have not been established. Therefore, it is impossible to obtain the complete configuration of the current vehicle during production or sales maintenance.
Therefore, the scheme is not fully applicabl

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] Such as figure 1 , 2As shown, first build the body controller configuration list. The software and hardware configurations of the body control system of different models are different, and the hardware configuration has been assembled on the production line, so the configuration list is mainly used to realize the shielding and enabling of software modules, or to set some parameters to achieve different function configuration. The configuration list is a two-dimensional table that lists the body function options corresponding to a certain model. These options come from both the mandatory configuration of the model and the user's personalized optional configuration. For example, the "collision unlock" function is mandatory for any model, and the "lazy automatic unlock" function is mandatory for high-end models, but optional for low-end models. I...

Abstract

The invention discloses a function and parameter on-line configuration method of an automobile integrated automobile body electronic control unit. The method includes: building a function and parameter configuration list of automobile body controllers of different types aiming at software function configuration and parameter setting in the integrated automobile body control unit (referred to as 'automobile body controller'), and writes the configuration list into a permanent memory of the controller by adopting a diagnosis protocol. After reading the configuration list, the controller software determines shielding and enabling of the software according to configuration items and parameters under the condition that the software and hardware are unchanged and sets physical setting of relative controlled objects according to the configuration parameters, so that difference in function configuration of different automobile types is achieved, and personalized customization and on-line function upgrading of systems are facilitated.

Description

technical field [0001] The invention relates to an online configuration method for functions and parameters of an automobile centralized vehicle body electronic controller. Background technique [0002] (1) Automotive electronic controller configuration [0003] 70% of automotive innovation comes from automotive electronics technology. Automotive electronics technology and products are the focus of future competition in the automotive industry. More and more electronic control units (ECUs) are used in automobiles to control mechanical and physical components to achieve the goals of environmental protection, driving safety, comfort and convenience. In mid-to-high-end cars, the number of ECUs has reached 50-80, and electronic components account for 20%-40% of the cost of the vehicle. In order to adapt to the constraints and restrictions of the natural environment, customs and laws and regulations of different countries and regions, and to meet the needs of different levels ...
