Description

METHOD FOR THE CUSTOMIZED PROGRAMMING OF THE CONTROL PARAMETERS OF A VEHICLE
Description
Technical Field
The present invention relates to the technical field of systems for the regulation of electrical and/or electronic parameters and deals with a method for customized programming of the control parameters of a vehicle.
State of the art
As known, there is greater use, also for commercial vehicles, of electronically controlled components both for the management of the engine and for the control of the various auxiliary devices for the operation of the vehicle, such as, for example, alarm systems, devices for engine performance monitoring, diagnostic devices in general.
The presence of such electronic components, and the consequent need to provide on board suitable CPUs for the management thereof, means that modern vehicles are generally arranged to allow a customized configuration of the operating parameters of the engine or of the various other devices installed.
By way of example, it is possible to intervene on parameters such as speed, maximum deliverable power, maximum torque at low speeds, in order to modify the vehicle’s performance and adapt it to the needs or driving style and possibly also to modify the consumption curve.
A first drawbacks of the current solutions which allow these adjustment interventions to be carried out consists in the fact that for any adjustment it is necessary to contact a specialized technician, who must intervene on the vehicle using specific control units for that single vehicle.
As matter of fact, each CPU installed inside a vehicle has its own programming code that varies according to the brand of vehicle, if not also within the same brand.
It follows that the owner of a vehicle that wants to modify one or more operating parameters or intervene on any device or control system of the vehicle is always forced to turn to a workshop specialized in working on that specific brand of vehicle. Therefore, the known solutions involve loss of time, less intuitiveness in terms of feasibility and increase in costs.
The utility of the service is therefore reset because the duration of the preparation is excessive compared to the needs of the user.
Last but not least, the parameters on which it is possible to intervene are very limited and are generally restricted to those relating to engine performance, while it is not possible to act on other vehicle circuits.
W02017/024320 discloses a method for managing firmware, settings and parameters of a motor vehicle controller that uses a local device, a client device and a system server. The local device is connected to the controller and is connected wirelessly to the client device. The client device is connected to the system server. The client device receives the engine data from the local device that receives the engine data from the controller and the client device sends the engine data to the server system. Firmware, settings and parameter updates are selected with the client device, sent to the local device and then sent to the controller.
However, this method does not require verification of the correct connection between the system server and the client device in order to verify its proper operation.
Furthermore, the client device does not appear to be applicable without distinction to each vehicle, regardless of the type of car and in particular the specific operating code of the CPU mounted thereon.
Scope of the invention
The object of the present invention is to overcome the above drawbacks by providing a method for customized programming of the control parameters of a vehicle that is characterized by high efficiency and relative economy.
A particular object is to provide a method for the customized programming of the control parameters of a vehicle that allows to intervene on the operating parameters of the vehicle in a quick, intuitive and simple manner.
Still another object is to provide a method for customized programming of the control parameters of a vehicle that does not require the intervention of a specialized technician. Still another object is to provide a method for the customized programming of the control parameters of a vehicle that can be implemented regardless of the type of vehicle and in particular the specific operating code of the CPU mounted thereon.
Not least object is to provide a method for the customized programming of the control parameters of a vehicle which allows to intervene on any device or service circuit or control of the vehicle and which is not limited to act only on the operating parameters of the engine.
These objects, as well as others which will become more apparent hereinafter, are achieved by a method for the customized programming of the control parameters of a vehicle which, according to claim 1, comprises the steps of connecting an interface for the acquisition of data from the vehicle control unit and/or the transmission of data to the control unit, connecting said interface to a central server for putting said central server in communication with the control unit, identifying the vehicle model through said central server, identifying the identification protocol of the vehicle control unit through said central server on the basis of the model identified in said step c) to define a specific communication protocol for the vehicle, sending a request to said central server from said interface for modifying the firmware of one or more electronic components of the control unit to change one or more operating parameters of the engine and/or of one or more service circuits, communicating between said server and said electronic control unit through said communication protocol to at least partially modify said firmware on the basis of said request.
Thanks to this combination of features, the user, for example the vehicle owner himself, will be able to communicate directly with the control unit via the interface regardless of the vehicle model, as the central server will be able to recognize the vehicle and find the specific communication protocol in its database to act on the control unit and send the parameters modification commands based on this protocol. Advantageously, in order to guarantee proper operation, the server will also perform a check on the interface and on the control unit of the vehicle. In particular, after said step b) of connection to said central unit, a step g) of identification of the interface by the central server is provided by requesting to the interface a serial number for the validation of said interface.
Furthermore, downstream of said step d) of identification of the communication protocol, a step h) is provided for acquisition by the central server of the firmware version by sending an identification signal to the control unit.
In particular, after establishing the connection with the control unit, a step g) of identification of the interface by the central server will be provided by request to the interface of a serial number so as to validate the same.
In this way it will be possible to check the software version of the control unit by sending a signal from the server to the vehicle control unit to acquire the software version.
This step has the main object of making it possible to restore the original version of the control unit in the event of an error during programming.
In this step, moreover, the server communicates to the interface the services available for the firmware version, should the existence of the original file occur.
Advantageous forms of execution of the invention are obtained according to the dependent claims.
Brief disclosure of the drawings
Further features and advantages of the invention will become more apparent in the light of the detailed description of a preferred but not exclusive embodiment of the method, illustrated as a non-limiting example with the aid of the attached drawing table wherein:
FIG. 1 is a scheme of a mode of execution of the method.
Best modes of carrying out the invention
Fig. 1 schematically illustrates a preferred but not exclusive mode of execution of a method for the customized programming of the control parameters of a vehicle.
The present method may be carried out to intervene on any of the operating parameters of the vehicle engine, such as for example instantaneous speed, maximum speed, power, maximum deliverable torque, consumption and/or on further operating parameters of other systems, such as the braking system, safety and/or alarm systems, other auxiliary systems.
The present control method will be applicable substantially to all the vehicles which have an internal control unit for the operating parameters of the engine and/or of one or more electronic service circuits.
The method essentially comprises a step a) for connecting an interface for acquiring data from the control unit of the vehicle and/or transmitting data to the control unit, a subsequent step b) for connecting the interface to a central server to put the latter in communication with the control unit and a step c) of identification by the central server of the vehicle model.
In particular, in order to identify the vehicle model, the server sends a request for a unique identification data to the control unit through the software residing in the interface.
Advantageously, this unique identification data will be the chassis number of the vehicle, so that the server can trace back through its database or by connecting in real time to a further database, also public, containing the association between the chassis and the vehicle.
Once the vehicle, or its brand, has been identified, the server will be able to identify (step d) the identification protocol of the vehicle control unit as it will have a database of all the communication protocols depending on the brand or model of the vehicle, so as to be able to define a specific communication protocol for the vehicle.
Once these preliminary set-up and recognition steps of the vehicle have been completed, it will be possible to act on the operating parameters of the engine system and/or on other systems or circuits in order to interrogate them and retrieve information, or perform functional tests, possibly to make changes by means of firmware changes of the various electronic components.
To this end, the interface, which will be connected to the central server preferably by direct or indirect internet connection, for example by means of a mobile communication device, will send (step e) a request to the central server for the modification of the firmware of one or more electronic components of the control unit to vary one or more operating parameters of the engine and/or of one or more service circuits.
For this purpose, the interface may be provided with its own data insertion and reading means, such as a keyboard and a display, but more preferably it will be adapted to communicate through a suitable software application with the mobile device, such as a smartphone or tablet on which this application is installed, so as to communicate with the server both in input and in output.
A step f) of communication between the server and the electronic control unit is then provided through the communication protocol to at least partially modify the firmware of the selected component through the interface on the basis of the request sent by the latter.
For example, since the performance of the vehicle is determined by the type of setting entered in the control units of the car’s engine, changing these data it is possible to obtain the results of the performances required by the end user.
A further application provides the possibility of performing performance tests, for example by performing an acceleration test on suitable locations, such as automobile tracks, so as to accumulate real-time information which, compared with sample information present in a database, allows the discovery of possible malfunctions of the engine of the vehicle, also allowing the immediate communication of the results to a central server through the internet connection.
Moreover, it will be possible to increase the anti-theft protection by interrogate the anti-theft system and checking for any system bugs that a potential thief could operate on, so as to eliminate these bugs.
In order to guarantee proper operation, the server will also perform a check on the interface and on the control unit of the vehicle.
In particular, after establishing the connection with the control unit, a step g) of identification of the interface by the central server will be provided by sending a request to the interface for a serial number so as to validate the same.
A check of the software version of the control unit may be provided downstream of the step d) for identifying the communication protocol by carrying out a step h) of acquisition by the central server of the firmware version by sending an identification signal to the control unit.
In particular, the server sends a signal to the vehicle control unit to acquire the software version and check (step i) contextually the presence of an original file for the control unit in question.
This step has the main object of making it possible to restore the original version of the control unit in the event of an error during programming.
In this step, moreover, the server communicates to the interface the services available for the firmware version, should the existence of the original file occur.
If the original file does not exist, the server checks if the reading for the identified firmware version (step m) is enabled.
If the reading protocol exists, the services are not enabled until the existence of an original file is proven through communication with the server.
Then, the server (step 1) creates the original file if in the checking step i) it is not possible to identify it, performing (step m) a check of the reading enable for the identified firmware version and making it possible to execute the step f) of communication exclusively following the creation (step n) of the original file.
The method according to the invention is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept expressed in the appended claims. All the details may be replaced by other technically equivalent elements, and the materials may be different according to requirements, without departing from the scope of protection of the present invention.
