Research and application on hybrid in-vehicle network in automotive control systems
The ways of connecting electronic control units (ECUs) developed from point-to-point wiring to single bus architecture, and to today networking. This paper presents a hybrid in-vehicle network solution of three segments of automotive sub-networks using two kinds of buses. The network covers ECUs which distribute in various parts of the vehicle and play different functions. High-speed CAN is adopted in powertrain and vehicle dynamic systems that must satisfy the need of critical real-time control applications. Low-speed and fault tolerant CAN is used for body electronics concerning about comfort and human machine interface (HMI) such as dashboard. LIN is faced to management of sensors and actuators at very low communication rate and cost. The three segments have been connected to gateway or bridge units. Examples are given to depict these functions and interplay -between control systems inside and between sub-networks. OSEK/VDX network management is used on CAN and LIN sub-networks in order to control bus sleep/wakeup and deal with join/removal of the nodes. The experimental results show the hybrid in-vehicle network performs well in automotive control systems.
