Abstract
A control system includes a controller configured to control communication between or among plural vehicle devices that control operation of a vehicle via a network that communicatively couples the vehicle devices. The controller also is configured to control the communication using a data distribution service (DDS) and with the network operating as a time sensitive network (TSN). The controller is configured to direct a first set of the vehicle devices to communicate using time sensitive communications, a different, second set of the vehicle devices to communicate using best effort communications, and a different, third set of the vehicle devices to communicate using rate constrained communications.
Claims18
A control system comprising:
- a controller configured to control communication between or among plural vehicle devices that control operation of at least one vehicle via a time sensitive network (TSN) that communicatively couples the plural vehicle devices,
- the controller is configured to control the communication between or among the plural vehicle devices using a data distribution service (DDS) in the TSN, the DDS including an object management group middleware communication standard for the plural vehicle devices to communicate as publishers and subscribers, the TSN configured to communicate different types of information between or among the plural vehicle devices based on whether communication of the different types of information needs to be completed within one or more designated periods of time for safe operation of the at least one vehicle, and
- the controller configured to direct one or more of an engine control unit or a traction motor controller of the plural vehicle devices to communicate using time sensitive communications, the controller configured to direct at least one of (a) a different, second vehicle device of the plural vehicle devices to communicate using best effort communications, or (b) a different, third vehicle device of the plural vehicle devices to communicate using rate constrained communications.
A control system comprising:
- a controller configured to control communication between different sets of vehicle devices that control operation of a vehicle, the controller configured to control the communication between or among the vehicle devices through an Ethernet network while the Ethernet network operates as a time sensitive network (TSN) and using an object management group middleware communication standard,
- the TSN configured to communicate different types of information based on whether communication of the different types of information need or do not need to be completed within designated periods of time for safe operation of the vehicle,
- the controller configured to direct one or more of an engine control unit or a traction motor controller of the different sets of the vehicle devices to communicate using time sensitive communications, the controller configured to direct best effort communications or rate constrained communications.
A control system comprising:
- a controller configured to control communications between plural vehicle devices onboard a vehicle through a time sensitive network (TSN) using an object management group middleware communication standard,
- the TSN configured to communicate different types of information based on whether communication of the different types of information need or do not need to be completed within designated periods of time for safe operation of the vehicle,
- the controller configured to direct one or more of an engine control unit or a traction motor controller of the plural vehicle devices to communicate using time sensitive communications, the controller configured to direct at least one of (a) a first set of the plural vehicle devices to communicate using time sensitive communications, (b) a different, second set of the plural vehicle devices to communicate using best effort communications, (c) a different, third set of the plural vehicle devices to communicate using rate constrained communications.
