Developing platform and control method for multifunction automobile electronic control unit

Abstract

The invention relates to the electronic field of autocar, and the whole circuit adopts regional design, altogether divided into power supply region, microprocessor region, input region, output region, communication debugging region and failure diagnosis region, and other functional regions. By loading the application software of the controlled object of the autocar, and inputting the needed input signals, it can control the target actuator based on the given control policy and makes on-line failure diagnosis on all the sensors and actuators, able to implement the development and design of autocar engine management system, auto gear box control system, ABS control system, autocar body control system, instrument and information system, and other electronic control systems. And the user only need possess the basis of C language so as to be able to make functional operation on all the interfaces and it can provide a friendly development environment of electronic control system for autocar and engine engineers of nonelectornic and computer specialties.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a development platform and control method for a multifunctional automotive electronic control unit, which can provide low-cost rapid prototype development tools and The platform accelerates the process of developing and commercializing automotive electronic control units. Background technique [0002] The development of automotive electronic control products represented by the engine electronic control unit requires the cooperation of multidisciplinary personnel, and the development is difficult and the cycle is long. In order to shorten the time and reduce the cost of developing prototypes, an automotive electronic control system that can be used for secondary development is required. In response to this demand, some advanced development tools currently on the market have been used in the development of engine electronic control units (ECUs), such as dSPACE's Microbox, whi...

AI Technical Summary

Problems solved by technology

These products are only used to control the gasoline engine, automatic transmission, or the powertrain integrated with the two, and lack the development of different control and integrated control systems that can be used in multiple systems of the car

At the same time, the existing control system has high requirements on the technical foundation of operators, and is not suitable for non-electronic automotive engineers to directly develop application control software.
