Control device with redundant CAN data bus e.g. for communication systems, has additional CAN data bus segment as redundant data bus segment provided between data bus terminals

摘要

A control device has an electronic central control appliance (4) which is joined to the electronic control devices (1-3), The central control device (4) and the electronic control devices are connected to one another via a CAN data bus. Between the data bus terminals (4,1) is an additional CAN data bus segment as a redundancy data bus segments. All the CAN data bus segments (10-13) are designed as switch-on and switch-off data bus segments. Included in the redundant data bus segment is a redundant CAN data bus ring open at one point and to which both the central device and the control devices (1-3) are connected. An independent claim is also included for a method for initiating a control device.
