A fault diagnosis device 80 includes an input unit 81 and a generation unit 82. The input unit 81 receives input of fault data obtained from a vehicle when a fault of the vehicle occurs and observation data observed in time series by each device of the vehicle until immediately before the fault occurs. The generation unit 82 generates a feature master that associates a content of the fault indicated by the fault data with features extracted from the corresponding observation data.

A driving data extracting apparatus for an autonomous driving vehicle includes: a storage module for storing driving data of the autonomous driving vehicle; a driving record module configured to manage recording of the driving data, to divide the driving data into a plurality of pieces depending on a frame size based on a diagnostic protocol of unified diagnostic services (USD), and to output the divided driving data by using a routine control (RID) service; a diagnostic module configured to receive a request for extraction of the driving data from an external data extracting equipment, to sequentially receive the divided driving data from the driving record module, and to sequentially transmit the driving data to the data extracting equipment; and a diagnostic communication module configured to perform diagnostic communication based on the diagnostic protocol of the USD between the data extracting equipment and the diagnostic module.

A selection support device that supports selection of a work machine to be used for work from among a plurality of work machines, the selection support device including: a history information acquisition unit configured to acquire history information on a use history of each work machine; a specifying unit configured to specify a degree of use of each work machine based on the history information; and a selection unit configured to preferentially select a work machine with a small degree of use as a work machine to be used for work.

An information processing apparatus compares a sense of use of a first vehicle with a sense of use of a second vehicle based on first information about one or more automobile components used by a user in the first vehicle that the user has used in the past in the first vehicle and second information about one or more automobile components used by the user in the second vehicle that is a vehicle candidate lent to the user. Then, the information processing apparatus notifies the user of result information related to a result of the comparing the sense of use of the first vehicle with the sense of use of the second vehicle.

An example method involves receiving, at a computing system, vehicle diagnostic information from a vehicle. The vehicle diagnostic information may include one or more sets of parameters corresponding to parameter identifiers (PIDs). The method further involves identifying a first set of parameters corresponding to a PID representing a state of a particular system of the vehicle and determining, using the first set of parameters, a current value of the PID. The method may also involve performing a comparison between the current value and a predetermined value for the PID and determining a health of the particular system of the vehicle such that the health reflects a difference between the current value and the predetermined value for the PID. The method may also involve displaying, by the computing system at a graphical interface, a vehicle health record representing the health of the particular system of the vehicle.

A method includes determining a test drive script (TDS) to perform while a tool monitors an electronic system in a mobile machine during a test drive of the mobile machine. The TDS includes an ordered sequence of drive cycle procedures (DCPs). The ordered sequence of DCPs begins with an initial DCP and ends with a final DCP. Each DCP is indicative of a respective mobile machine state. The TDS includes a first particular DCP associated with both a first particular mobile machine state and a first condition pertaining to the first particular mobile machine state. The method also includes outputting a representation of at least a portion of the TDS. Additionally, the method includes determining and outputting one or more of: status information corresponding to achieving the first particular mobile machine state or status information corresponding to achieving the first condition pertaining to the first particular mobile machine state.

A method for diagnosing a vehicle electrical system of a vehicle including a plurality of intercommunicating arithmetic logic units. A diagnostic application is executed on one arithmetic logic unit of the plurality of arithmetic logic units. The diagnostic application receives a diagnostic inquiry from an external diagnostic unit. The diagnostic inquiry is analyzed by the diagnostic application. Based on the content of the diagnostic inquiry, the diagnostic application sends data to at least one arithmetic logic unit and/or sends a diagnostic response to the external diagnostic unit.

A method of remote communications with an on-board diagnostics (OBD) system of a vehicle includes connecting a vehicle communications device to a connector of a vehicle's OBD system, connecting a remote communications device to a connector of a vehicle tool device, and establishing a network communications link between the vehicle-communications device and a remote communications device. The vehicle communications device receives communications at the vehicle-communications device from the vehicle's OBD system through the connector. A bit stream of the received communications is analyzed over an interval of time. The widths of one or more bit pulses are estimated based on the analyzing of the bit stream. A bit rate of the OBD system is determined based on the estimated widths of the one or more bit pulses. Based on the determined bit rate of the OBD system, bidirectional communications are established between the OBD system and the tool device using the established network communications link between the vehicle-communications device and the remote communications device.

A system for on board diagnostic (OBD) vehicle communications that includes a vehicle communications device having a pin-connector adapted for connecting to a vehicle's OBD system and a network interface configured to perform network communications with a remote communications device connected with a vehicle scan and/or programming tool using a compatible pin-connector. The remote communications device includes a network interface configured to perform network communications with the vehicle communications device. The vehicle communications device is programmed and configured to receive communications from a vehicle's OBD system through its pin-connector and selectively filter communications based on message type received from OBD system. The selectively filtered communications are forwarded through a network to the remote communications device using the network interfaces.

An electronic battery tester or battery charger for testing or charging a storage battery including electrical connectors configured to electrically couple to a terminals of the storage battery. Circuitry couples to the electrical connectors and is configured to test or charge the storage battery. An input signal is received related to a battery which is suitable for use with the vehicle.
