Data distribution system and method for distributing data in a vehicle

摘要

A data distribution system for a vehicle includes a data distributor module that is communicatively coupled with a data acquisition module that obtains values of available data parameters related to operation of the vehicle, a service module that provides functions for the vehicle based on the values, and a memory. The data distributor module receives a request list from the service module that includes one or more requested data parameters of the available data parameters. The data acquisition module stores the values of the requested data parameters in the memory. The data distributor module retrieves the values of one or more of the requested data parameters from the memory and communicates the values that are retrieved to the service module for the service module to use the values that are retrieved to provide the functions for the vehicle.

1. A data distribution system for a vehicle, the distribution system comprising:
a data distributor module including one or more processors, the data distributor module configured to be communicatively coupled with a first service module that includes one or more processors and provides one or more functions for the vehicle based on values of data parameters, the data distributor module configured to receive a first request list from the first service module that includes one or more requested data parameters, and a plurality of data acquisition modules including one or more processors, the data acquisition modules communicatively coupled with the data distributor module, each of the data acquisition modules configured to obtain the values of different data parameters, wherein the data distributor module is configured to determine which of the data acquisition modules obtain each of the requested data parameters and to send a filtered list to each data acquisition module that obtains at least one of the requested data parameters, the filtered list including the one or more data parameters that are obtained by the receiving data acquisition module, wherein, in response to receiving the filtered list, each receiving data acquisition module is configured to obtain the values of the one or more requested data parameters included in the received filtered list and store the values in one or more shared memories, the data acquisition modules further configured to transmit one or more response lists to the data distributor module that indicate locations in the one or more shared memories where the values of the one or more requested parameters are stored, wherein, in response to receiving the one or more response lists, the data distributor module is configured to retrieve the values of the one or more requested data parameters from the one or more shared memories based on the one or more response lists and transmit a message to the first service module that includes the values of the one or more data parameters requested by the first service module for the first service module to use the values to provide the one or more functions for the vehicle.
