Problems solved by technology

Therefore, engine control events that occur at a rate higher than the transfer rate capacity of the vehicle's data bus may be ignored in some prior art diagnostic systems, which may result in an inaccurate or more time-consuming diagnostic procedure

Embodiment Construction

[0021] According to one embodiment, figure 1 A remote diagnostic system 11 is shown. In one embodiment, remote diagnostic system 11 includes central electronic data processing system 10 capable of communicating with vehicle electronics 46 via communication network 36 and wireless infrastructure 44 .

[0022] Central electronic data processing system 10 and wireless infrastructure 44 are coupled to electrical communications network 36 (eg, the Internet). One or more service technician terminals (eg, first service technician terminal 40 and second service technician terminal 42 ) are capable of communicating with central electronic data processing system 10 via communication network 36 . One or more service technician terminals ( 40 , 42 ) are capable of communicating with vehicle electronics 46 via communications network 36 and wireless infrastructure 44 .

[0023] In an alternative embodiment, a service technician or user may use a local diagnostic computer 38 that communica...

Abstract

A method and system for performing diagnostics or software maintenance on a vehicle comprises a data processor (71) for performing a particular task. A resource monitor (74) is arranged for determining if resource consumption of the data processor (71) for the respective particular task exceeds a threshold amount of resource consumption. A loop counter (75) is arranged to increment a loop counter (75) in a data storage device (56) associated with the data processor (71) if the resource consumption for the respective particular task exceeds the threshold amount. A poison task module (65) is capable of designating the particular task as a poison message if the data processor (71) has been rebooted a maximum number of times as indicated by the loop counter (75).

Description

technical field [0001] The present invention relates to methods and systems for performing diagnostics or software maintenance of a vehicle. Background technique [0002] In some prior art, remote diagnosis and analysis of vehicle performance may require the storage and transfer of entire configuration files from the central processing center to the vehicle electronics. Such transfers tend to inefficiently use one or more communication channels between the central processing center and the vehicle electronics. Land-based communication channels may not be feasible where the vehicle and associated vehicle electronics are located in rural areas. [0003] Available or unreliable, necessitating a satellite communication channel. For example, transmission of the entire configuration file, and thus remote diagnosis, may not be economically feasible, requiring a more expensive satellite communication channel to handle the significant data throughput throughout the configuration fi...
