Abstract: A system comprises a processor that is programmed to define a plurality of vehicle groups based on vehicle specification data and define a plurality of sub-groups for each of the vehicle groups based on environmental data and sensor data received from each of a plurality of vehicles. The processor is programmed to adjust fuel tank leak detection classifiers for the sub-groups based on ground truth data. The ground truth data include, for each of the plurality of vehicles, a leak detection status and a leak test result.

Abstract: A system includes at least one processor configured to, in response to receiving a VIN from a remote vehicle, transmit to the vehicle a parameter definition selected based on fields of the VIN to configure an ECU of the vehicle to enter a logging mode to capture, aggregate, and send operational data of the vehicle, and a bandwidth configuration file for a modem of the vehicle based on historical throughput requirements associated with operational data. The parameter definition may include a reporting application configured to be executed by a processor of the ECU to generate a processed parameter from a raw parameter associated with vehicle operation. Also, the parameter definition may include updated firmware for the ECU, and the reporting application is configured to be executed by the ECU after the updated firmware is installed in the ECU.

Abstract: A vehicle includes an onboard controller(s) coupled to a wireless transceiver, which are configured to connect to a remote server, and to respond to a remote software update message for a vehicle from the remote server(s). In response, the controller(s) download a software update to the vehicle from the remote server(s). The controller(s) are further configured to detect a vehicle idle state, to determine whether the vehicle is unattended, such that the software update may proceed. If the idle state is detected, and in response to the remote software update message, the controller(s) configure the vehicle to a program mode, having vehicle conditions that include key on, transmission in park, and engine off. If the program mode configurations are successful, then the controller(s) update and/or flash the downloaded updates to in-vehicle, onboard computer processing systems and controller(s), which may include for example an engine control unit (ECU), among others.

Abstract: An automotive vehicle may include a processor configured to buffer records of vehicle information created at a scheduled acquisition rate, and to buffer event files of vehicle information created upon the occurrence of predetermined triggering events. The processor may be further configured to cause the buffered records to be wirelessly transmitted on a last-in first-out basis if a signal strength in a vicinity of the vehicle is greater than a first predetermined threshold, and to cause the buffered files to be wirelessly transmitted if the signal strength is greater than a second predetermined threshold.

The controller(s) are further configured to detect a vehicle idle state, to determine whether the vehicle is unattended, such that the software update may proceed. If the idle state is detected, and in response to the remote software update message, the controller(s) configure the vehicle to a safe mode, having vehicle conditions that include key on, transmission in park, and engine off. If the safe mode configurations are successful, then the controller(s) update and/or flash the downloaded updates to in-vehicle, onboard computer processing systems and controller(s), which may include for example an engine control unit (ECU), among others.

Abstract: A vehicle electronic control unit (ECU) may control a vehicle subsystem and be configured to receive from a remote server via a vehicle telematics unit (TCU), a parameter definition of a processed parameter to be computed by the ECU; generate the processed parameter according to the parameter definition based on a raw parameter generated by the ECU; and send the processed parameter to a vehicle data buffer associated with the ECU for upload to the remote server via the TCU.

Abstract: Electronic modules in motor vehicles are reflashed without encountering errors due to insufficient electrical power becoming available during a reflashing. A server system stores a database of update files together with data corresponding to a respective current draw and a respective reflash time associated with the respective update files when applied in each respective vehicle. A vehicle sends pedigree information to the server system which then identifies relevant update files and corresponding current draw and reflash time data for the particular vehicle. The relevant update files and corresponding data are sent to the particular vehicle. A state of charge of a battery in the vehicle is determined. A depleted state of charge is estimated that would remain after applying a relevant update file. The update file is not applied if the estimated depleted state of charge is less than a predetermined state of charge.

Abstract: A computer-implemented method includes determining that a connection to an update server should be established. The method also includes establishing a wireless connection with the update server. The method further includes sending at least a VIN number to the update server and downloading one or more module updates corresponding to the sent VIN number. Also, the method includes verifying the one or more downloaded updates. The method further includes flashing one or more modules to which the one or more updates correspond. Additionally, the method includes verifying the functionality of each module which has been flashed.
