Methods and systems for switching vehicle data transmission modes based on detecting a trigger and a request for a vehicle data message
First Claim
1. A method comprising:
- receiving, at a first device, multiple vehicle data messages, wherein each of the multiple vehicle data messages includes a data identifier and data value transmitted from a vehicle, and wherein the first device is not a component of the vehicle;
detecting, by a processor of the first device, a first trigger to switch from a prior vehicle data transmission mode (VDTM) to a first VDTM for transmitting in their entirety over a communication link from the first device to a second device at least some of the multiple vehicle data messages, wherein the second device is not a component of the vehicle;
determining, by the processor based on (1) the first trigger, and (2) one or more requests the first device transmits to the vehicle to request vehicle data messages or one or more requests the first device receives from the second device to request vehicle data messages, the first VDTM for transmitting in their entirety over the communication link from the first device to the second device at least some of the multiple vehicle data messages;
switching, in response to detecting the first trigger and determining the first VDTM, the first device from operating in the prior VDTM to the first VDTM, wherein some of the multiple vehicle data messages include vehicle data messages received while the first device is operating in the first VDTM; and
transmitting the vehicle data messages received while the first device is operating in the first VDTM in their entirety over the communication link from the first device to the second device according to the first VDTM.

Abstract
A vehicle interface device (VID) switches to a first vehicle data transmission mode (VDTM) from a prior VDTM based on a trigger for transmitting vehicle data messages (VDMs) and which VDMs have been requested at a vehicle data receptor (VDR). A decreased data transfer rate may result from selecting the first VDTM such that some portions of VDMs received while the VID is operating in the other VDTM are transmitted to the VDR from the VID and other portions of those VDMs are not transmitted to the VDR from the VID. An increased data transfer rate may result from selecting the first VDTM such that some portions of VDMs received while the VID is operating in the first VDTM are transmitted to the VDR from the VID whereas those same portions would not have been transmitted to the VDR from the VID if the VID was still operating in the prior VDTM.

17. A vehicle interface device comprising:
-
a service data link connector configured to establish a connection with a vehicle to receive multiple vehicle data messages, wherein each of the multiple vehicle data messages includes a data identifier and data value transmitted from the vehicle, and wherein the vehicle interface device is not a component of the vehicle; a first transceiver configured to establish a communication link with a second transceiver, wherein the second transceiver is not a component of the vehicle nor of the vehicle interface device; a processor connected to the service data link connector and to the first transceiver; and a non-transitory computer-readable medium containing computer-readable program instructions that, when executed by the processor, cause the vehicle interface device to perform a set of functions, wherein the set of functions includes; detecting a first trigger to switch from a prior vehicle data transmission mode (VDTM) to a first VDTM for transmitting in their entirety over the communication link to the second transceiver, at least some of the multiple vehicle data messages; determining, based on (1) the first trigger, and (2) one or more requests the vehicle interface device transmits to the vehicle to request vehicle data messages or one or more requests the vehicle interface device receives from the second transceiver to request vehicle data messages, the first VDTM for transmitting in their entirety over the communication link from the first transceiver to the second transceiver at least some of the multiple vehicle data messages; switching, in response to detecting the first trigger and determining the first VDTM, operation of the vehicle interface device from the prior VDTM to the first VDTM, wherein some of the multiple vehicle data messages include vehicle data messages received while the vehicle interface device is operating in the first VDTM; and transmitting, from the first transceiver, the vehicle data messages received while the vehicle interface device is operating in the first VDTM in their entirety over the communication link from the vehicle interface device to the second transceiver according to the first VDTM. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 27)
