`
`A system is used with a
`computer—controlled machine
`having
`rea1—time
`electrical
`signals corresponding to the
`operation of a machine,
`for
`real—time data processing of
`electrical
`signals
`occurring
`within the machine.
`The
`machine includes a controller
`(112)
`and an event node,
`such as an actuator, sensor,
`or
`indicator
`(122), with an
`interconnect system disposed
`between
`the
`controller
`and
`the
`event
`node
`for
`exchanging data. The system
`includes
`an
`event
`data
`recorder
`(136)
`coupled to
`the interconnect system for
`selectively storing event data.
`The machine comprises an
`automotive vehicle.
`The
`event recorder need not be
`connected to the serial data
`output of the controller but
`is directly coupled to the
`real—time
`electrical
`signals
`occuiring
`between
`the
`controller and its associated sensors and actuators. This allows for direct monitoring and diagnostics of the real—time system activity within
`ems which can be missed by or even caused by the controller. The event data recorder
`the automotive vehicle, including intermittent prob
`can be triggered (124) to store the data by a user input by pressing a push—button positioned on a wire—less transmitter that communicates
`with the event data (150) recorder. Feedback is provided to the user indicating that the event data recorder is storing the event data.

`
`BACKGROUND
`In recent years, there has been a rapid increase in the use of microcontrollers
`and microprocessors (the core elements of most computer-type equipment) to
`enhance the performance and sophistication of a variety of complex machines, most
`notably motor vehicles. These “computerized” machine systems invariably consist
`of a group of sensors, which convert a variety of physical phenomena (such as
`pressure, temperature, velocity, etc.) into electrical signals ("DATA") that are used
`to convey information about these phenomena, a group of actuators and indicators,
`which convert electrical signals ("DATA") into a variety of physical phenomena
`(such as heat, rotation, switch closure, light, etc.), and one or more controllers,
`which receive the electrical signals fiom sensors and — based at least in part on the
`information obtained from the sensors — produce electrical signals to control
`actuators and indicators. These electrical signals, or data, can take various forms,
`fiom DC voltage levels which correspond directly to the state of a sensor, to data
`
`20 messages controlling and reporting system operation.
`The rapid deployment of computerized motor vehicle control systems has
`been accompanied by a corresponding increase in the occurrence of short-term
`intermittent failures. Due to the “closed—loop” nature of most computerized machine
`systems, a momentary anomaly at any point in the system can frequently result in a
`chain-reaction effect, wherein the original anomaly produces an immediate reaction
`from another element in the loop, which then produces another immediate reaction

`
`-2-
`
`from a third element in the loop, etc. Unless the source of the initial momentary
`anomaly is being monitored at the exact instant that the problem occurs, and in such
`the source of the initial anomaly, it is
`a way as to identify it as in fact being
`sometimes all but impossible to identify and correct the problem.
`The interconnections between the sensors, actuators, indicator
`lished by means of wires and suitable connectors. In ord
`controllers are accomp
`al signals which are present within the
`most effectively access the electric
`monitoring the activity of the
`computerized machine system, for purposes of
`al signals, diagnosis of the electrical signals, and]or extem
`electric
`s necessary to establish physical connections to one or more of
`electrical signals, it i
`the elements of the machine system. A convenient place to make such connections
`is at the connectors that exist within the machine system. Various systems have
`been devised for the purpose of accessing electrical signals within motor vehicles
`and other electronic systems. Most commonly, these systems have taken the form of
`
`s, and
`
`er to
`
`al control of the
`
`wire—piercing probes.
`Some prior art systems have utilized a breakout box technique, in which one
`or more wiring harness connectors with a motor vehicle are disconnected from their
`mating connectors on a vehicular electronic device and plugged into an external
`akout box includes an integral cable assembly that is long
`breakout box. The bre
`0 be located at a distance from the vehicular
`
`enough to allow the breakout box t
`electronic device and that terminates in connector
`vehicul
`ar electronic device from which the vehicular wiring harne
`
`s appropriate for plugging into the
`
`ss connectors were
`
`10
`
`15
`
`20
`
`disconnected.
`The breakout box is constructed such that each signal in the motor vehicle
`25 wiring harness connectors is connected through to the vehicular electronic device
`and is also connected uniquely to one of several probe terminals, whereby each and
`any of the signals existing within the vehicular wiring harness connectors can be
`temal diagnostic equipment. Such systems are
`accessed for connection to ex
`d cumbersome, and are thus impractical

`hampered by the fact that they are large an
`for use in instances where they would remain installed fo
`modern motor vehicles now have many of their electronic

`
`SUMIVIARY
`The problems associated with the identification of the source of an
`intermittent failure in a motor vehicle produces an extremely inconvenient side-
`effect, which is the requirement that the motor vehicle be removed from its normal
`(owner’s) use in order that a trained service technician can operate the motor vehicle
`and observe appropriate test equipment while waiting for the intermittent failure to

`as a service. technician watches for the problem to occur.
`Various systems have been devised for the purpose of monitoring and
`recording performance data for a motor vehicle, and these systems have enjoyed
`of success in contributing to the identification and repair of
`cts. Most commonly, these systems have taken the
`intermittent control system defe
`form of devices which monitor a serial data port on a control computer that is part of
`the vehicular control system, storing vehicle performance data which is generated by
`
`only a limited degree

`
`have access to perform
`
`the serial port in a recording device.
`Such systems are hampered by the fact that the control computer does not
`ance data from all devices within the vehicular system (e.g.,
`ystem, which is a key performance parameter in
`the pressure level within the fuel s
`y the fact that the data presented is the
`modern motor vehicle engine systems) and b
`control computer’s “interpretation” of the system activity, rather than a reliable
`indication of the actual system performance. Further, performance data is output
`from the control computer in serial mode (relatively slow in comparison to system
`activity) by sequencing through each of the system elements and performance
`a time period between data points for a given
`parameters in turn. This results in
`element in the system that can be sufficientl
`failure to occur between data points, which can result in
`for the failure or, worse, identification of the incorrect element as the cause of the
`
`y long so as to allow an intennittent
`failure to identify a cause

`
`failure.

`
`Other types ofvehicular monitoring and recording systems utilize specially
`installed sensors which are not part of the control system of the vehicle, monitoring
`and storing data fiom these sensors in a recording device. Such systems are
`typically designed for long-term monitoring ofvehicular performance, and while
`providing information that is useful in particular applications, they have difficulty
`providing the information that is required to identify an intermittently faulty element
`within the vehicular control system.
`Due to the foregoing disadvantages of currently available vehicular
`monitoring and recording systems, servicing ofmotor vehicles with intermittent
`failures has long been a time—consurning, expensive, and frustrating experience for
`service technicians and vehicle owners. Within the automotive industry specifically,
`intermittent vehicles, and the failure to repair them quickly and cost—effectively, may
`represent the single greatest cause of customer dissatisfaction and of dealer re-
`purchase of problem motor vehicles.
`Accordingly, a system and method are provided that monitors and records
`any of a variety of electrical signals occurring in or around a computer-controlled
`machine. The monitoring and recording system is particularly useful for recording
`electrical signals occurring in a motor vehicle, for the purpose of identifying the
`cause of anomalies, including those of the intermittent type, in the operation ofthe
`
`10
`
`15
`
`20
`
`25
`
`30
`
`motor vehicle.
`In one embodiment, a system is used with a computer-controlled machine
`having real—time electrical signals corresponding to the operation ofthe machine, for
`real-time data processing of electrical signals occurring within the machine. The
`machine can include a controller and an event node, such as an actuator, sensor, or
`indicator, with an interconnect system disposed between the controller and the event
`node for exchanging data. The system can include an event data recorder coupled to
`the interconnect system for selectively storing event data. The machine can
`comprise an automotive vehicle which includes the controller. The event recorder
`need not be connected to the serial data output of the controller but can be directly
`coupled to the real—time electrical signals occurring between the controller and its
`associated sensors and actuators. This allows for direct monitoring and diagnostics

`
`of the real—time system activity within the automotive vehicle, including intermittent
`problems which can be missed by or even caused by the controller.
`According to other aspects, the event data recorder stores event data which is
`not monitored by the controller. The event data recorder can include an onboard
`power source to process the event data in the absence of any external power source.
`According to other aspects, the event data recorder can be triggered to store
`the event data by a user input, for example, by actuating an actuator, for example,
`pressing a push-button. In one embodiment, the actuator is mounted within reach of
`the operator of the vehicle. For example, the actuator can be mounted on a steering
`wheel of the vehicle, such as the inside of the steering wheel. The actuator can also
`be coupled to a wire-less transmitter that communicates with the event data recorder.
`The event data recorder can also be triggered to store the event data by an
`
`unintentional stall of the engine or a shut—down of a vehicular control system of the
`
`vehicle. The event data recorder can further be triggered to store the data by an
`
`10
`
`15
`
`alarm indication of a vehicular control system. In one embodiment, the alarm
`
`indication is a warning lamp.
`
`According to further aspects, the event data recorder includes at least one
`circuit board shock—mounted to a housing of the event data recorder. The circuit
`board can include a first cushion member thereon to provide a cushion between the
`circuit board and the housing. A second cushion member can be further positioned
`between the first cushion member and the housing. A bolt or screw passes through
`the first cushion member and the second cushion member for securing the circuit
`
`board to the housing.
`According to further aspects, a feedback system, such as the flashing of a
`warning indicator lamp of the automotive vehicle, is provided to alert the user that
`the event data recorder is installed and working properly. The feedback system can
`
`also alert the user to various operating states of the event recorder by flashing the
`
`warning indicator lamp at different frequencies or for distinct durations.
`According to yet further aspects, a cabling device is provided that connects
`the event data recorder to at least one electrical system of the machine without
`damaging any existing electrical Wiring. The cabling device can include a plurality
`of contact pins connected to a plurality of wires for inserting into electrical
`

`
`connection points of the machine. The cabling device can include a multi-pin in—line
`connector to provide an interface to an electronic sensor, such as a fuel pressure
`sensor, which is temporarily attached‘ to the vehicle.
`Alternatively, the cabling device is custom made or particularly adapted for
`the machine which can include at least one connector plug that connects to a
`computer of the machine, at least one cable jack that connects to sensors and/or
`actuators within the machine, a plurality of feedthrough wires that connect the
`connector plug and cable jack, and at least one instrument connector that connects at
`least one of the feedthrough wires to the event data recorder. The cabling device can
`further include an auxiliary connector that connects to the instrument connector.
`According to further aspects, a display device which is able to be coupled to
`the event data recorder to access the event data stored in the event data recorder is
`provided to visually display the event data for diagnostic purposes. The data can be
`downloaded to an external computing device which can include the display device.
`In accordance with further aspects, a system for use with an automotive
`vehicle to facilitate determining the cause of an intermittent failure includes a
`processor that controls operation of an event data recorder, a recording device that
`receives real time event data from the vehicle and stores the same for later analysis,
`and a wire-less transmitter including an actuator that, when actuated by a user,
`initiates storing of the event data. The recording device can store a predetermined
`amount of real—time data upon initiation of the event data recorder or can store the
`
`contents of a continuous loop of event data.
`In accordance with other aspects, a system and method are provided to
`convey information from a device connected to a vehicle which includes an
`electronic circuit that flashes an indicator lamp of the vehicle in predetermined
`patterns under control ofthe device. The pattern can convey information to the user,
`such as the device is installed properly or the device is performing a commanded
