Definitions
- the present invention relates to a method for studying the state of equipment, in particular equipment of a vehicle powertrain such as an electric propulsion machine, an actuator, a double clutch or a single clutch or another voltage converter.
- the known predictive maintenance methods do not make it possible to reproduce the behavior of the equipment whose predictive maintenance is to be carried out with sufficient precision.
- the object of the invention is to meet this need and it achieves this by means of a method for studying the state of equipment, the method comprising the following steps :
- the invention can thus allow the behavior of the second equipment to be an image of the behavior of the first equipment.
- the first equipment is for example in the possession of the user while the second equipment is located on the premises of the manufacturer of the first equipment. Thus, this manufacturer can reproduce in its premises or elsewhere the behavior of the first equipment via the second equipment.
- the method may comprise the step according to which the state in which the first equipment is located is deduced from the state of the second equipment. This deduction is preferably done via computer processing but can in some cases be done via visual inspection by a user. According to one aspect of the invention, it is therefore the second piece of equipment that is studied and not the first piece of equipment, and the conclusions drawn from the study of the second piece of equipment are considered to be valid for the first piece of equipment as well.
- the method can thus make it possible to carry out predictive maintenance, since the state of wear of the second equipment makes it possible: to deduce the state of wear of the first equipment, and to estimate the risks of future degradation of the first equipment.
- the method can alternatively allow, in the event of failure or degradation of the first equipment, to benefit for the manufacturer from the presence of the second equipment whose behavior reproduces that of the first equipment. This avoids having to return the first piece of equipment to the manufacturer, which can save time and reduce the effort required to identify the causes of this failure or degradation.
- the application to the second equipment of instructions generated on the basis of the information recorded from the first equipment is not intended to deduce the state of the first equipment but to study the behavior of the second equipment when it is subjected to the same constraints as the first equipment. It is thus possible to benefit from the behavior of the first equipment to develop or validate the second equipment.
- the retrieval of information relating to the evolution of the parameter during use of the vehicle can be carried out via a wireless communication network, for example via a 3G, 4G or 5G network.
- this information retrieval can be carried out while the vehicle is in motion, or partly while the vehicle is in motion.
- the vehicle has, for example, a communication interface module that sends this information over the communication network.
- the server can be a single server, for example located at the manufacturer of the first equipment, or implement several distributed servers.
- the recovery of data and their recording can be done via cloud computing.
- the second equipment can be a virtual model of the first equipment.
- the second piece of equipment is thus a model produced via a computer system of the first piece of equipment and the instructions are entered into this computer system so as to reproduce the behavior of the first piece of equipment.
- This computer system uses, for example, Matlab®, Script® or Mathematica®.
- the second equipment is a physical model of the first equipment.
- This model corresponds for example to a physical object (“hardware”) operating according to the same principles as the first piece of equipment.
- the second equipment corresponds for example to a prototype used during the development of the first equipment.
- the second device is a copy of the first device.
- the first and the second equipment are for example two parts differing only by their serial number. In the latter case, the method can make it possible to have a quasi identity between the state of the second equipment and that of the first equipment.
- the second equipment When the second equipment is a physical model of the first equipment or a copy of this first equipment, the second equipment can be placed on a test bench, so as to be able to best reproduce the conditions of use of the first equipment.
- the parameter linked to G use of the first equipment can be at least one of: an equipment supply current, an equipment supply voltage, an equipment rotation speed or a motor torque exerted by the equipment or any other parameter. This may be the number of openings or closings when the first piece of equipment is a valve, in particular for a vehicle powertrain. All or part of these parameters are, for example, transmitted to the waiter.
- the setpoints applied to the second device can ensure that the latter also presents the same values for this or these output parameters.
- the setpoints applied to the second equipment can consist of the direct application of these values for this or these parameters.
- the information relating to the evolution of the parameter during the use of the first equipment is recovered, it is also possible to recover information related to the climatic environment in which the first equipment operates. It is possible, if necessary, to generate additional instructions so that the second equipment operates in this same climatic environment.
- the information related to the climatic environment in which the first equipment operates includes, for example, at least one of: the temperature, the pressure, the hygrometry and the salinity in the air, or any other information.
- This or this information related to the climatic environment in which the first equipment operates can be measured via sensors.
- all or part of this information relating to the climatic environment of the first equipment can be obtained via numerical estimators, the latter using for example as input values data not referring to the climatic environment and deducing to using a pre-established map or any other means, such as a neural network, information relating to the climatic environment of the first equipment.
- the retrieval of information relating to the evolution of the parameter can be carried out continuously.
- the server is continuously supplied with information relating to the evolution of the parameter during the use of the first device.
- the first piece of equipment can be integrated into a vehicle, in which case the server retrieves this information from a communication interface module of the vehicle.
- the recovery of information relating to the evolution of the parameter can be carried out on an ad hoc basis. This recovery can occur on a fixed or random periodicity. This recovery can also occur when a predefined condition is verified, for example stopping or starting the vehicle when the first equipment is integrated into this vehicle.
- the evolution of the parameter can take place during a given time sequence, and the setpoints for the second equipment can be generated so as to respect this given time sequence.
- the use of the second equipment thus respects the cycles of use of the first equipment, allowing the behavior of the second equipment to be even closer more than that of the first equipment.
- the ranges of use of the second equipment can correspond to those of the first equipment, by their duration and/or by the time interval between two successive ranges of use, for example.
- this use can however be done in a way offset with respect to that of the first equipment, for example only at night to avoid noise or other nuisances for the people close to the second equipment.
- the instructions applied to the second equipment may correspond to a range of use of the second equipment that is longer or shorter than according to the time sequence and/or the time interval between two successive ranges of use of the first equipment will not correspond to the time interval between two successive ranges of use of the second equipment.
- the first piece of equipment may be on board a vehicle, or be suitable for being on board a vehicle.
- the first piece of equipment is for example a physical component on board the vehicle or suitable for being on board the vehicle.
- vehicle designates any form of mobility with purely electric, hybrid, thermal or other propulsion. “Vehicle” thus encompasses a machine rolling on land via four, three, two wheels or any other number of wheels, or a machine moving in the air or on water, or even in space.
- An example of a vehicle is an automobile.
- the first piece of equipment may belong to the powertrain of the vehicle being for example an electrical machine for propelling the vehicle, or a voltage converter or an actuator or a single or double clutch.
- the first piece of equipment is an electric vehicle propulsion machine, it may be a machine whose shaft is integral in rotation:
- the shaft of the electric machine can be integral in rotation with the crankshaft of the heat engine of the vehicle, when the powertrain comprises such a heat engine.
- the rotating electrical machine may comprise a pulley or any other means of connection to the rest of the vehicle's powertrain.
- the electric machine is for example connected, in particular via a belt, to the crankshaft of the heat engine of the vehicle.
- This rotating electrical machine can have a nominal supply voltage of 12V, 48V, or more, for example a nominal voltage value greater than 200V, for example greater than 300V. As a further variant, this nominal supply voltage may be less than 12V.
- the first piece of equipment is a voltage converter, it may be an inverter/rectifier supplying a propulsion machine of the vehicle or a DC/DC voltage converter of the on-board network.
- the invention can also be applied in other fields, for example in computing or communication or even in household appliances.
- Another subject of the invention is a system for implementing the method described above, this system comprising:
- FIG. 2 schematically represents an environment within which another part of the method according to the embodiment of Figure 1 is implemented.
- FIG. 1 An environment 1 within which part of a method according to one embodiment of the invention can be implemented. This embodiment consists in studying the state of a first device using a second device.
- the first equipment 2 is a propulsion machine of a vehicle powertrain.
- the vehicle here is an automobile but other applications are possible.
- the propulsion machine allows the propulsion of an electric or hybrid vehicle, having in the example considered a nominal voltage of 48V or other, for example a voltage whose value is greater than 200V, in particular 300V, being for example less than 800V.
- the information relating to the evolution of one or more parameters related to this rolling is transmitted via a communication interface module 4 to a network of wireless communication 5.
- This network 5 implements for example 3G, or 4G or 5G technology.
- Several parameters are for example studied, such as the speed of rotation of the first device 2, its supply voltage, its supply current or even the motor torque supplied.
- the communication interface module 4 also collects information related to G climatic environment in which the first equipment 2 operates.
- This information comprises for example at least one of: the temperature, the pressure and the hygrometry of the environment in which the first equipment 2 evolves.
- This information can be obtained via sensors or via digital estimators 6.
- this information can be obtained on the network 5 other than from the vehicle, for example by cooperation with access or content providers.
- the network 5 allows the transmission of this information to a server which is for example produced via a decentralized computer 8. It is thus possible to record in this server 8 the information retrieved in relation to the use of the first equipment 1. If necessary, these information can be supplemented by information representing the source of electrical energy supplying this first equipment 2
- This transmission of information can be done continuously, the information being transmitted to the server 8 permanently, or at least when the vehicle is running or at least when the ignition is on.
- this transmission of information is only done on an ad hoc basis.
- This transmission is done for example only according to a fixed or variable periodicity, depending for example on the age of the first equipment 2 and/or on its number of hours of use and/or on the detection of the end of a journey .
- the information thus recovered and recorded is transmitted by the network 5 to a second equipment 10 visible in FIG. 2.
- This second equipment 10 is in the example considered a copy of the first equipment 2, differing from this first equipment 2 only by its serial number.
- the second equipment can be a virtual model, produced via a computer system, of the first equipment 2 or a physical model of this first equipment 2, for example a prototype of this first equipment 2.
- the second equipment 10 is mounted on a test bench and in an enclosure 11 in which the climatic conditions are modifiable.
- the invention also applies when the possibility of modifying the climatic conditions for the second equipment item 10 does not exist.
- the recovery of the information recorded in the server 8 is done in the example described via a computer 12, but any equivalent computer system such as a tablet is valid.
- This computer 12 is here configured to generate, on the basis of the information received from the server 8, instructions to be applied to the second equipment 10 so that its behavior reproduces that of the first equipment 2.
- the computer 12 also generates in the example describes additional instructions allowing control members 13 and 14 of enclosure 11 to best reproduce the conditions climatic conditions in which the first piece of equipment 2 was operating when the information relating to the evolution of the parameters on the basis of which the instructions are generated by the computer 12 was recorded. temperature in the enclosure 11 and the device 14 makes it possible to adjust the humidity in this enclosure 11.
- the instructions applied by the computer 12 to the second piece of equipment 10 are for example generated so as to that the supply current of the electric machine and/or its speed of rotation are as close as possible, for example identical, to those related to the first equipment item 2.
- the embodiment of the invention described thus makes it possible, via the second equipment 10, to have an image, in particular as faithful as possible, of the first equipment 2.
- a diagnosis as to the state of the first equipment 2 can be carried out remotely, and this diagnosis can make it possible to decide on a predictive maintenance operation of the first equipment 2 or to understand the reasons for a breakdown or degradation of the first equipment 2.
- the information relating to the evolution of the parameter for the first equipment 2 can correspond to a given time sequence, and the generation of the instructions by the computer 12 can be done in such a way that this time sequence is respected by the second equipment 10 Thus, if the evolution of the parameter has been observed during a given duration for the first equipment 2, the application of the instructions to the second equipment 10 can correspond to the same duration for the evolution of the parameter for the second equipment 10 .
