Component-Based ECU Design Method of Passenger Car Information Integrated Control System

Based on in-vehicle network technology and ECU (Electronic Control Unit), passenger car information integrated control system implements correlative real-time control of passenger car functions. ECU is the core of system function implementation. Currently, passenger car ECU is designed according to special function requirement. Passenger car model has diversity because of the difference of market requirement and technology level. Variety of function requirement causes high cost and problem of maintenance for ECU development and application. In this paper, component-based ECU design method of passenger car information integrated control system is presented. Based on the analysis of holistic function of ECU, ECU components of passenger car information integrated control system are designed. In order to implement "component-ECU-system" 3-level development mode, ECU component configuration method and process are put forward. According to the function requirements of WG6100ENH model natural gas city bus information integrated control system, the system ECUs are designed. This case verifies the efficiency of the method presented in this paper.
