Modular seat actuation control system and communication method

摘要

A seat actuation control system includes at least one seat having a plurality of seat devices and a plurality of control modules interconnected over a communication bus. Each module is associated with a corresponding seat control device and is configured to control its corresponding seat device. Each module includes a processor and a memory coupled to the processor and storing program instructions therein which include receiving a status packet from each of the other control modules over the communication bus, processing the status packet for updating the overall system status, and actuating the seat device based on the overall system status. The program instructions further include determining status of the corresponding seat device, generating a status packet including the status information, and broadcasting the status packet to the other modules over the communication bus.

主权项

1. A method for peer-to-peer communication between a plurality of modules of a vehicle seat network, each module being configured to control a corresponding seat device, the method comprising:
monitoring by each of the plurality of modules a transmit sequence for determining whether the module is a next module in the sequence; in response to determining by one of the modules that the module is the next module in the transmit sequence, generating by the module a status packet including status information of the corresponding seat device; monitoring by the module expiration of a rest period; and in response to expiration of the rest period, broadcasting by the module the generated status packet over the vehicle seat network for receipt by other ones of the plurality of modules for actuating one or more seat devices.
