Abstract

This invention relates to a central control unit of a car carried network and a method for controlling and managing the car-carried network, among which, the central control unit includes a microprocessor CPU, a CAN T/R device, a CAN controller, a CAN bus, interface, a regulated supply, an input/output interface circuit and a switch signal test circuit. The network system is composed of several electronic control units with CAN interface, the PCU and all nodes of the car-carried network keep communication therefore, the CPU stores node database originally matched, the central control unit and other nodes interact via data communication of matched data request, response and network management request and response to realize the network management of configuration, diagnosis, sleep and awaking.

Description

technical field [0001] The present invention relates to a vehicle-mounted network (CAN controller local area network) central control unit and a method for managing and controlling the vehicle-mounted network, which relates to a central control unit (abbreviated as vehicle body computer) of a vehicle-mounted network system and its network management and system configuration and diagnosis. method. Background technique [0002] At present, there are more and more phenomena of using electronic control devices to control certain functions of automobiles, such as airbags and ABS. The work of each control device is independent, there is no system, and there is no organic connection. Isolated, without other relevant technical data at the time of failure, lack of configuration, diagnosis and management of all electronic control devices of the entire system. Contents of the invention [0003] The purpose of the present invention is to address the above shortcomings, to provide a v...
