International Classification:

G06F 1336

US Classification:

710315, 710303

Abstract:

A novel and improved engine data system for collecting, displaying and analyzing engine/vehicle data is provided. The system have advantageously results in a more effective, convenient, portable and low cost method of monitoring and processing vehicle data. The vehicle data system includes a handheld computer containing operating system software adapted to operate the handheld computer in accordance with a data protocol different from a vehicle bus protocol and a handheld microprocessor for executing the operating system software. The system importantly includes an adapter for creating a data pathway between a vehicle bus connector and an external data port provided on the handheld computer which is physically incompatible with the engine bus connector. The adapter includes a data port connector for connection with the external data port, a bus compatible connector for connection with the engine bus connector, a battery power supply separate from the power supply of the handheld compuer and an adapter microprocessor powered by the battery power supply and connected via the data pathway with the bus compatible connector for protocol conversion of the data received from the engine bus. An engine data adapter system for creating a data pathway between the engine data bus and the handheld computer while determining the start and stop of messages received from the data bus and adding message identifiers to the engine data so as to minimize the required data processing by the handheld computer.

International Classification:

G01M 17/00
G06F 15/16

US Classification:

701 33, 709200, 701 29

Abstract:

An adapter is disclosed for allowing communications between a vehicle control computer coupled to one or more vehicle communications networks and a remote computer. The one or more vehicle communications networks may be configured for data communications in accordance with, for example, an SAE J1939 or an SAE J1587 communications protocol, or the like. The adapter includes a first interface for operatively coupling to the one or more communications networks and a second interface including a universal serial bus (USB) controller configured for operatively coupling to the remote computer. The USB controller may be coupled to the remote computer via a device port and a host port, and/or a USB on-the-go port. In any case, the vehicle control computer and remote computer communicate through the adapter via the vehicle communications network and the first and second interfaces.

US Classification:

709/249000, 701/001000

Abstract:

A communications bridge between a communications network carried by a motor vehicle and configured for communications according to a first protocol and a remote system configured for communications according to a second protocol, includes a first interface configured for coupling to the communications network, a second interface configured for coupling to the remote system, and a digital signal processor (DSP) configured to process multiple operations per instruction cycle The DSP receives information from the communications network via the first interface, converts this information to the second protocol and transmits the information converted to the second protocol to the remote system via the second interface. The DSP further receives information from the remote system via the second interface, converts this information to the first protocol and transmits the information converted to the first protocol to the communications network via the first interface.

Assignee:

Cummins Engine Company, Inc. - Columbus IN

International Classification:

B60K 3116

US Classification:

364426041

Abstract:

The present invention is directed to a system for detecting the tampering of the vehicle speed signal in a vehicle having electronic engine control. An algorithm that forms part of the present invention is operable to detect a tampering mode producing a constant transmission out-of-gear signal to the vehicle speed sensor input of the electronic controller, and tampering mode disallowing the electronic controller from acting upon a vehicle owner or manager-programmed top gear ratio, or maximum vehicle speed limit. In response to detecting a possible vehicle speed signal tampering condition, a vehicle speed signal tampering fault code is logged into a memory portion of the controller, a vehicle operator warning lamp is activated and the engine speed is electronically controlled to a vehicle owner/manager programmable maximum engine speed limit. The system is operable with a number of transmission embodiments including manual and automatic types intended for either on or on/off highway applications.
