Abstract
The invention relates to a method for collecting data from a motor-driven vehicle, which is provided with a microprocessor with memory for storing a particular quantity of data. The data is provided by a number of sensors connected to the vehicle and its motor and is recorded and compiled into a specific data file upon each recording occasion, when it its ascertained that conditions are fulfilled for recording a data file. This is recorded as a non-erasable reference data file. Upon subsequent occasions when the conditions are fulfilled, a number of successively erasable data files are successively recorded and stored within the predetermined quantity of data.
Description
Technical field
The present invention relates to a kind of data method that is used for gathering the vehicle of motor driven, this vehicle is furnished with a microprocessor that has a storer, this storer is used for storing the data of some, these data are by providing with some sensors that vehicle is connected with its motor, and are recorded and compile particular data file in each record these data on opportunity.
Background technology
For modern vehicle, for example when fault, fault finding is a difficulty and time-consuming.Simultaneously, cause to ensure (guarantee) problem, and vehicle occurs and whether correctly used, or the problem whether damaged by any way by the user of vehicle.In addition, whether can make the problem eliminating and recover normal if can confirm to change vital parts (such as turbine-compressor) rapidly, this also is very favorable.
These problems especially can appear on the heavy vehicle, for example suffer the lorry of the long-distance transport of high strength use.In addition, these vehicle operations are optimized in the power bracket near Max. hp. relatively.Fuel economy for these vehicles also has very high requirement.
Therefore need can the continuous recording engine data method and system.A kind of known system with this purpose be constantly record data write until storage unit full, subsequently in storage unit at first the data of record can be rewritten the historical data before therefore can only obtaining in certain section time range unceasingly.
The memory capacity of storage unit has determined length during this period of time.If can reduce memory capacity is that economic advantages are arranged very much.
Summary of the invention
Therefore the objective of the invention is to realize a kind of method of the vehicle image data from motor driven, this kind method makes saves cost and efficient system becomes possibility.
For this purpose, the feature of method of the present invention is may further comprise the steps: confirm to have reached the condition of recording data files, with data file as not erasable reference data file; On the opportunity that reaches condition subsequently, in predetermined data volume, continue record and store a series of continuous erasable data files.The result of She Ji method is in this way, and data volume not only comprises not erasable reference data, also comprises the erasable data that deposit in, and the solution that this means system is to save very much cost.
Advantageous embodiment of the present invention will specifically describe in following claim.
Description of drawings
Hereinafter the present invention is described particularly with reference to embodiment, these embodiment as shown in drawings:
Fig. 1 is motor torsional moment figure;
Fig. 2 be under the declare record situation engine speed along with the chart of the variation of time.
Embodiment
The method according to this invention is intended to be used for recording status information, and described status information comprises a plurality of operating parameters of the CD-ROM drive motor that is installed on the vehicle.The scope that these operating parameters can use according to the motor type that adopts this method, motor and change according to the information category that is obtained.Therefore, the exploitation of novel sensor can be opened up the possibility that obtains the motor operations status information.And new legislation also needs to increase new operating parameter.The following examples are the example that this status information can constitute.
For example, the status information that writes down under and same situation can comprise following operating parameter: cooling fan speed, car speed, accelerator position, engine load, fuel-supplying pressure, oil pressure, turbocharger pressure, turbine temperature, ambient pressure, coolant temperature, crankcase pressure, intake air temperature, oil temperature, fuel load, engine speed, EGR (exhaust gas recirculation), the total driving distance and the total run time of motor.
This status information can be used for measuring the situation of motor, and research is in the historical trend of motor in serviceable life.An electronic diagnostics instrument can be used for reading before these status informations are shown to the user and handling it.
In this embodiment, there are four kinds of different incidents to cause this operation of executive logging status information.After each incident, in case satisfy all record conditions, executive logging operation at once.Status information is stored in the rolling register, perhaps is stored in the special storer, and this depends on the incident that causes recording operation.Memory construction can design with following mode:
When motor is brand-new, and when the condition of all records all satisfies for the first time, just carry out first state recording.This record is rewritten never.
When motor moved with corresponding specific hourage of the normal trial period of motor after, carry out second state recording.This record is rewritten never.
In changing motor, during important element, for example when changing turbine unit,, can excite two the interior remaining memory enters of storer that are used for the special state record by the electronic diagnostics instrument.These instigated recordings can be rewritten on the basis of rolling.In case all record conditions satisfy, state recording at once that be excited.
The general register that is used for recording status comprises 15 memory enters in this embodiment, can be rewritten on the rolling basis in suitable minimum time interval.In case all record conditions satisfy, the malfunction and detection recording of state recording that the horse back execution time triggers or use diagnostic tool.
For but the different operating parameter in state recording can comprise relevant repeating data, must satisfy a plurality of prerequisites after, could carry out exciting or the state recording of Time Triggered.For example, the sensor that contains in record condition must operate as normal.In addition, motor can not be operated under the so-called motor protected mode.
Suppose and satisfy these preconditions, and state recording excites or Time Triggered, the further condition of state recording need be satisfied.For example; the temperature of motor liquid coolant must be in a specific scope; engine load must very high (near peak torque) or is needed a very high moment of torsion; air pressure must be normal; the motor protected mode must can not be activated, and engine speed must reduce in a specified engine speed scope.
Condition about engine load is meant that engine load must be very high in a special time period, for example in a few times in second.If motor is " health " not, might when torque demand is very high, be used to reduce system's meeting torque limiting of discharging.
If other condition all satisfies, just can test about reducing the condition of engine speed, this condition just can take place when engine speed reduces in engine speed range.If when engine speed increased in this scope, it is invalid that these conditions become, and sees Fig. 2 at once.
The X-axis of Fig. 1 is represented engine speed, and Y-axis is represented moment of torsion, and Fig. 1 has shown moment of torsion Figure 10 that of combustion engine is common.Fig. 2 has illustrated the relation along with the engine speed change of time, is a condition of record when engine speed reduces by a specific rotation speeds value C in engine speed range A-B.This is in order to guarantee engine operation in full load, to confirm when collecting data in this way.D shows that the condition along with the time satisfies situation.
The electronic diagnostics instrument that links to each other with vehicle data systems when all situations satisfies, can be used for the instigated recordings data file.When surveying, vehicle trouble especially can adopt this method.
The present invention is not limited only to embodiment recited above, may also have some further development and correction in following claim scope.
