`ABSTRACT
`An apparatus is provided for diagnosing the state ofhealth of
`a vehicle and for providing the operator of the vehicle With a
`substantially real-time indication of the efficiency of the
`vehicle in performing an assigned task with respect to a
`predetermined goal. A processor on-board the vehicle moni-
`tors sensors that provide information regarding the state of
`health of the vehicle and the amount of work the vehicle has
`done. In response to anomalies in the data from the sensors,
`the processor records information that describes events lead-
`ing up to the occurrence ofthe anomaly for later analysis that
`can be used to diagnose the cause ofthe anomaly. The sensors
`are also used to prompt the operator of the vehicle to operate
`the vehicle at optimum efficiency.

`
`ingly, in an effort to improve the up time or operating time of
`the vehicle, it is very important to monitor the critical vital
`signs ofa vehicle. However, in addition to simply monitoring
`these vehicle critical vital signs, it is even more important to
`know what caused a vehicle vital sign to reach a critical
`condition that, if continued, will cause failure ofa component
`or subassembly. When taken as disparate items, tracking
`either vital signs or production parameters gives only a partial
`picture of a vehicle’s operation.

`TECHNICAL FIELD OF THE INVENTION
`
`The invention generally relates to the identification of
`anomalies in the operation of a vehicle and, more particularly,
`to the collection and analysis ofdata derived during operation
`of a vehicle that provides a basis for diagnosing the cause of
`anomalies in the vehicle’ s operation.
`
`BACKGROUND OF THE INVENTION
`
`20
`
`25
`
`SUMMARY OF THE INVENTION
`
`It is the general object of the invention to diagnose the
`cause of anomalies in the values ofthe state-of-health param-
`eters of a vehicle.
`
`It is a related object of the invention to employ the forego-
`ing diagnosis to control the operation and use ofthe vehicle to
`reduce the severity and number of anomalies ofthe values of
`the state-of-health parameters of the vehicle, thereby extend-
`ing the useful life ofthe vehicle while maintaining production
`goals.
`It is also an important object of the invention to provide a
`historical record of the values of the condition and perfor-
`mance parameters of a vehicle, which can be used to schedule
`future maintenance and utilization of a vehicle.
`
`It is yet another important object ofthe invention to provide
`to the user of a vehicle real-time information regarding the
`degree with which the vehicle is being utilizedii.e., the
`maximization of all performance and condition parameters
`within their normal ranges. It is a related object of the inven-
`tion to signal the user of a vehicle whether the utilization of
`the vehicle at the moment is optimum and to also indicate
`whe her the user has utilized the vehicle over a known time
`
`period (e.g., a work shift) in a manner that meets expectations.
`These and other objects and advantages of the present
`inve ition, as well as additional inventive features, will be
`apparent from the description of the invention provided
`herein.
`
`B ‘iefiy, the invention identifies a poor state of health of a
`vehicle and provides data regarding the recent use of the
`vehicle that can be used to effectively diagnose the cause of
`the poor health. Operating the vehicle beyond its normal
`operating conditions stresses components and subassemblies.
`If st‘essed to an extreme or for a long period of time, the
`component or subassembly may fail. On the other hand,
`under-utilization of the vehicle results in undue operating
`expenses and inefficient use of the vehicle. Therefore, the
`invention also provides a visual prompt to the operator of the
`vehicle on a substantially real-time basis an evaluation of the
`efficiency of the vehicle’s operation with respect to a prede-
`termined norm for an assigned task. With these two aspects of
`the invention, the operator of the vehicle is encouraged to
`operate the vehicle efficiently while at the same time being
`mindfiil that overstres sing the vehicle to make up for a period
`of inefficiency will be recorded and noted by the operator’s
`supervisors.
`An electronic processor on-board the vehicle acquires vital
`sign data and work-related data at predetermined time inter-
`vals from sensors mounted to the vehicle for providing a set of
`vital sign data and a set ofwork data. The sensors that provide
`vital sign data sense parameters of the vehicle’s subassem-
`blies and components that are indicative of their state of
`health. The sensors that provide the work data sense param-
`eters that are indicia of the task performed by the vehicle and
`of the amount of work the vehicle has done in performing the
`task. A memory is associated with the electronic processor
`and stores the vital sign and work data acquired by the pro-
`

`
`All vehicles today have various sensors for identifying and
`tracking critical “vital signs” of a vehicle. In their simplest
`form, these sensors include an oil pressure gauge, a water
`temperature gauge and an electrical system charging/dis-
`charging gauge. In more sophisticated vehicle systems, these
`vital signs may be expanded to include the condition of the
`brake system, transmission shift indicator, and so forth. In 35
`fact, for every component or subassembly of a vehicle, a
`sensor can be adapted for indicating whether that component
`or subassembly is operating in a routine or “critical” statei
`i.e., a state that if maintained will cause the component or
`subassembly to fail.
`Like the monitoring of vital signs, it is also known to
`employ sensors on-board a vehicle to track performance of
`the vehicle. An example of such an on-board system is illus-
`trated in U.S. Pat. No. 4,839,835 to Hagenbuch. By sensing
`and monitoring vehicle parameters related to the task being
`performed by a vehicle, a record can be established that
`describes how effectively the vehicle is performing and pro-
`vides the operator ofthe vehicle with information from which
`future operations of the vehicle can be planned to maximize
`oerformance. Task-related parameters are parameters such as
`load carried by a vehicle, grade of the road on which the
`vehicle is operating, loads hauled per hour, tons hauled per
`10111', and the like. In gene
