Description

TECHNICAL FIELD

The present invention regards a remote testing system for a vehicle and a pair of adapters for such system.
In particular, the invention regards a pair of OBD adapters and an OBD remote testing system for a road vehicle, for example a motor vehicle.

PRIOR ART

As known, usually a vehicle, for example a road vehicle such as a motor vehicle, a truck or motorcycle, is provided with an OBD (On-Board Diagnostics) system, i.e. capable of performing on-board diagnostic operations, comprising several control units configured for automatically monitoring the vehicle status and its sub-systems.
The OBD system further comprises a first connector associated to the vehicle and connected to the control units, suitable to receive an output signal of the control units representing the vehicle status.
The system further comprises a testing device provided with a second connector joined to the first connector and suitable to be connected to the first connector to transmit the output signal of the control units to the testing device. In addition, the testing device is configured for decoding the output signal of the control units.
In the known systems, the testing device is provided with a connecting cable associated - at one end - to the testing device - at the opposite end - to the second connector.
Thus, in use, the testing device is always physically close to the vehicle. For example, in a motor vehicle the first connector is usually arranged in the dashboard beneath the steering wheel and, thus, the user is forced to get into the motor vehicle cockpit holding the testing device to perform the diagnosis of the means with considerable discomfort and operative difficulty. Alternatively, systems in which the testing device and the second connector can communicate in a wireless fashion in particular through Bluetooth technology are known. In such known systems, the second connector comprises an emitter suitable to transmit the output signal of the control units to a receiver associated and connected to the testing device.
However, given that the Bluetooth technology has a short radius, the user must be in the vicinity of the vehicle, for example a few meters away, and generally in the same environment. Thus, the control units may communicate with the testing device only when the operator is present, for example when the vehicle is in the garage.
Furthermore, such systems require the use of specific testing devices, which are usually very expensive.
An object of the present invention is to overcome the aforementioned drawbacks of the prior art through a solution that is simple, rational and inexpensive.
These objects are attained by the characteristics of the invention, which are outlined in the independent claim. The dependent claims outline preferred and/or particularly advantageous aspects of the invention.

DESCRIPTION OF THE INVENTION

An embodiment of the invention, in particular provides a remote testing system for a vehicle comprising: a diagnostic unit installed on-board the vehicle and configured for generating a signal representing the vehicle status and sending said signal outside the vehicle through a first connecting socket; a testing device configured for receiving and processing the signal representing the vehicle status and provided with a first connecting plug.
According to the invention, the system comprises a first adapter comprising a second connecting plug, configured for coupling with the first connecting socket of the diagnostic unit, and a remote communication unit configured for transmitting the signal representing the vehicle status outside the first adapter; a second adapter comprising a remote communication unit configured for receiving the signal representing the vehicle status from the communication unit of the first adapter, and a second connecting socket configured for coupling with the first connecting plug of the testing device.
Thanks to this solution, the system may be made up of a diagnostic unit and a conventional testing device, for example via cable, that can be placed in mutual remote communication by means of the communication unit of the first and the second adapter without the operator having to change the testing device with considerable economic burden.
According to another aspect of the invention, the system may comprise at least one communication device configured for placing the communication units of the first and the second adapter in mutual communication by means of a wireless network.
Thus, this enables expanding the communication capacity between the first and the second adapter.
According to a further aspect of the invention, said at least one communication device may comprise a router or a modem.
Thus, this enables placing the first and the second adapter in communication via telephone, internet or WiFi connection expanding the radius of action. According to another aspect of the invention, said at least one communication device is a mobile communication device.
Thus, the expansion of the radius of action of the system is enabled by means of common and versatile communication devices without the operator having to buy a dedicated device with considerable economic burden. Furthermore, thanks to such devices, communication is guaranteed also outside a garage or other organised facilities and, for example, the system can be used by a rescue vehicle which, during a road rescue operation, for example sends the signal representing the vehicle status to the garage so that it can be processed by the testing device.
Furthermore, the at least one communication device can be configured for connecting to the first and/or to the second adapter through a Bluetooth or WiFi connection.
Thus, the connection between the communication device and the adapters is obtained through a simple and reliable communication system.
Furthermore, the system may comprise at least one first communication device configured for connecting to the first adapter, and at least one second communication device configured for connecting to the second adapter, said first and second communication device being configured for establishing mutual communication via a wireless network.
Thanks to such devices, communication is also guaranteed outside the garage or other organised facilities.
According to another aspect of the invention, at least one from among the first and the second adapter may comprise a voltage regulator connected to the respective second connecting plug and/or the second connecting socket and configured for enabling electrical supply to the respective adapter from an external source.
Thanks to such solution, the first adapter and/or the second adapter do not require their own internal source of electrical supply, for example a battery, thus being economic and compact.
According to another aspect of the invention, the diagnostic unit is configured for generating a signal according to a predetermined standard and the second adapter can be configured for selectively replicating said standard. Thus, the second adapter is capable of replicating any standard serving as a universal adapter.
According to a further aspect of the invention, the second adapter may comprise a control microprocessor connected to connectors of the second connecting socket according to an interconnection diagram that is a function of the standard of the signal, the second adapter further comprising a switch configured for selectively modifying the interconnection between the control microprocessor and the connectors of the second connecting socket as a function of a command received from the testing device adapting the interconnection diagram to the particular standard of the vehicle.
Thus, the second adapter may easily replicate the standard of any diagnostic unit.
Furthermore, the invention provides a pair of adapters for a remote diagnosis system of a vehicle, provided with a diagnostic unit having a first connecting socket and a testing device having a first connecting plug, said pair comprising: a first adapter comprising a second connecting plug, suitable for coupling with the first connecting socket of the diagnostic unit, and a remote communication unit configured for transmitting a signal representing the vehicle status outside the first adapter; a second adapter comprising a remote communication unit configured for receiving the signal representing the vehicle status from the communication unit of the first adapter, and a second connecting socket suitable for coupling with the first connecting plug of the testing device.
Thus, there is provided a pair of adapters that enable a known system of the conventional type to perform a remote analysis of the vehicle status without the operator having to change the testing device with considerable burden of costs. In addition, the operator does not have to carry the device along all the time thus making the use of the system easier and safer.

As described above, the testing system 1 operates as follows.
In use, the first adapter 12 is coupled to the diagnostic unit 10 of the vehicle 2 and, in particular, the second connecting plug 121 of the first adapter 12 is coupled with a stable and releasable connection directly to the first connecting socket 101 of the diagnostic unit 10.
The first adapter 13 is also connected to the first communication device 14 (for example a smartphone) by means of the communication unit 120 thereof, for example by means of a Bluetooth connection.
The second adapter 13 is coupled to the testing device 11, in particular, the second connecting socket 131 of the second adapter 13 is coupled with a stable and releasable connection to the first connecting plug 111 of the testing device 11.
The second adapter 13 is also connected to the second communication device 15 (for example a smartphone) by means of the communication unit 130 thereof, for example by means of a Bluetooth connection.
The first and the second communication device 14,15 are mutually connected by means of a wireless network, for example a telephone connector.
Using the testing device 11, an operator selects the standard corresponding to the type of vehicle 2 so as to send to the switch 113 a programming command to modify the interconnections between the connectors 111 of the first connecting plug 110 and the control means 112 of the first connecting plug 110.
Such programming control is sent to the second adapter 13, for example through the plug-socket connection, so as to modify the interconnections between the connectors 132 of the second connecting socket 131 and the means 133 for controlling the second connecting socket 131.
In particular, such interconnections are modified so that the second connecting socket 131 takes a configuration such to replicate the first connecting socket 101 of the diagnostic unit 10.
The second adapter 13 sends the programming command to the first adapter 12 by means of the communication unit 130 thereof and through the wireless network provided by the communication devices 14,15.
The first adapter 12 receives the programming command through the communication unit 120 thereof and the switch 124 modifies the interconnections between the connectors 122 of the second connecting plug 121 and the microprocessor 123 of the second connecting plug 121 so as to adapt them to the standard of the first connecting socket 101 of the diagnostic unit 10. Thus, the first adapter 12 obtains access to the signal Y representing the vehicle status 2.
The first adapter 12 sends the signal Y to the second adapter 13 by means of the communication unit 132 thereof and through the wireless network provided by the communication devices 14,15.
Thus, the testing device 11 may receive the signal Y from the second adapter 13 which precisely replicates the first connecting socket of the diagnostic unit 10. Upon receiving the signal Y, the testing device 11 may process it to enable the operator to assess the vehicle status 2.
The invention thus conceived is susceptible to numerous modifications and variants all falling within the inventive concept.
In addition, all details can be replaced by other technically equivalent elements.
Basically, the materials used as well as the shapes and contingent dimensions, may vary according to the needs without departing from the scope of protection of the claims that follow.
