Data distribution system and method for distributing data in a vehicle

A data distribution system for a vehicle, the distribution system comprising:

• a data distributor module including one or more processors and a shared memory having a tangible and non-transitory computer readable storage medium, the data distributor module communicatively coupled with the shared memory;
• wherein the data distributor module is configured to receive requests for data parameters from a plurality of service modules that each includes one or more processors, the data parameters relation to operations of the vehicle and the service modules configured to perform one or more functions for the vehicle based on values of the data parameters, the data distributor module configured to filter the requests for the data parameters, and communicate the filtered requests for the data parameters to a plurality of data acquisition modules that each includes one or more processors, the data distributor module filtering the requests for the data parameters and communicating the filtered requests based on which of the data acquisition modules obtain each of the data parameters, each data acquisition module that receives a filtered request configured to obtain the values of the data parameters according to the corresponding filtered request and store the values of the data parameters in the shared memory;
• wherein the data distributor module is further configured to at least one of:
• retrieve the values of the data parameters from the shared memory based on memory indices of the stored data parameters received from one or more of the data acquisition modules after the one or more data acquisition modules store the values of the data parameters in the shared memory, the memory indices indicating locations in the shared memory where the values of the data parameters are stored, and the data distributor module configured to communicate the values of the data parameters that are retrieved from the shared memory to the plurality of service modules for use by the plurality of service modules in providing the one or more functions for the vehicle:
• or
• communicate the memory indices that are received from the one or more data acquisition modules to the plurality of service modules for the service modules to retrieve the values of the stored data parameters from the shared memory based on the memory indices for use by the plurality of service modules in performing the on more functions for the vehicle.

A method for distributing data in a vehicle, the method comprising:

• receiving a first request list for values of one or more requested data parameters, the requested data parameters related to operations of the vehicle and used to perform one or more functions for the vehicle;
• determining which of one or more data acquisition modules that each includes one or more processors acquires the values of each of the one or more requested data parameters and forming one or more filtered lists that associates each of the one or more requested data parameters with the data acquisition module that acquires the values of the respective data parameter;
• sending the one or more filtered lists to the one or more data acquisition modules for the one or more data acquisition modules that receive the one or more filtered lists to acquire the values of the data parameters in the received filtered list and store the values in a memory having a tangible and non-transitory computer readable storage medium;
• and
• in response to receiving one or more response lists from the one or more data acquisition modules that indicate locations in the memory where the values of the one or more requested data parameters are stored, retrieving the values from the locations in the memory based on the one or more response lists in order to transmit the values to one or more service modules that each includes one or more processors, the one or more service modules configured to use the values to perform the one or more functions for the vehicle.

A method for distributing data in a vehicle, the method comprising:

• receiving requests for data parameters from a plurality of service modules that each includes one or more processors, the data parameters relating to operations of the vehicle and the service modules configured to perform one or more functions for the vehicle based on values of the data parameters;
• filtering the requests for the data parameters based on which of a plurality of data acquisition modules obtain each of the data parameters that are in the requests, the data acquisition modules each including one or more processors;
• communicating the requests that are filtered as filtered lists to one or more of the data acquisition modules, the one or more data acquisition modules that receive one of the filtered lists obtain the values of the data parameters in the respective filtered list responsive to receiving the filtered list and store the values of the data parameters in a shared memory with memory indices representative of where the values are stored;
• and
• in response to receiving the memory indices from the one or more data acquisition modules, at least one of:
• retrieving the values of the data parameters from the shared memory based on the memory indices, and communicating the values of the data parameters that are retrieved from the shared memory to the plurality of service modules for use by the plurality of service modules in performing the one or more functions for the vehicle;
• or
• communicating the memory indices to the plurality of service modules for the service modules to retrieve the values of the stored data parameters from the shared memory based on the memory indices.

A data distribution system for a vehicle, the distribution system comprising:

• a request list submodule configured to receive requests for values of one or more available data parameters from plural service modules of the vehicle, the data parameters relating to operations of the vehicle, the service modules each include one or more processors and are configured to provide one or more functions for the vehicle based on values of the data parameters;
• a filter submodule configured to filter the requests based on which of plural data acquisition modules of the vehicle acquire the values of each of the data parameters in the requests, form filtered lists that each include the requested data parameters that are acquired by a different one of the data acquisition modules, and transmit the filtered lists to the corresponding data acquisition modules for each of the data acquisition modules that receives one of the filtered lists to acquire the values of the data parameters on the respective received filtered list and store the acquired values in a shared memory having a tangible and non-transitory computer readable storage medium, the plural service modules and the plural data acquisition modules each including one or more processors;
• a reader submodule configured to retrieve the values of the data parameters in the requests from the shared memory based on one or more response lists that are received by the reader submodule from the data acquisition modules that store the values of the data parameters in the shared memory, the one or more response lists indicating locations in the shared memory where the values of the data parameters are stored;
• and
• a publication submodule configured to form one or more messages for transmission to the service modules, wherein the one or more messages include the values of the data parameters that are requested by the service modules, wherein the request list submodule, the filter submodule, the reader submodule, and the publication submodule at least one of each include one or more processors or are commonly grouped within one or more processors.
