Definitions

  • the present invention relates to a vehicle diagnostics port adaptor.
  • Many modern vehicles such as cars, vans and heavy goods vehicles (HGVs) are fitted with an electronic control unit that monitors engine performance.
  • the unit is generally referred to herein as an Engine Control Unit (ECU), but it is sometimes referred to as a Power-train Control Module (PCM) or an Engine Control Module (ECM).
  • ECU data can be accessed for analysis by means of an On-Board Diagnostics (OBD) port located within the vehicle.
  • OBD On-Board Diagnostics
  • ECU data can be analysed by a specialist, for example during a service or if the vehicle develops a fault, to get a better understanding of the engine characteristics of the vehicle.
  • Engine emissions can also be modelled using data obtained from the OBD port. More recently, ECU data has been used to monitor engine parameters while the vehicle is being driven, to provide real-time visual feedback to the driver.
  • a vehicle diagnostics port adaptor comprising a connector housing comprising a connector that is connectable to a vehicle diagnostics port, a transmitter housing comprising a data transmitter, and a data cable arranged to permit data flow between the adaptor housing and the transmitter housing, wherein the connector housing is separable from the transmitter housing.
  • the connector housing is connectable to a vehicle On- Board Diagnostics (OBD) port.
  • OBD On- Board Diagnostics
  • Conventional OBD port adaptors are relatively large and easy to handle since they are generally only used for diagnostics and analysis purposes when the vehicle is stationary and not when it is being driven. Conventional adaptors might, however, distract a driver when driving. For example, a conventional adaptor may obstruct driving to some extent if the vehicle's OBD port is located in the footwell. It can also interfere with driving if the conventional adaptor is plugged into an OBD port which is located adjacent to the gearstick.
  • the relative positions of the two housings can be chosen so as to minimise any interference with driving. Indeed, it may not be necessary to reduce the size of any of the standard individual components of conventional adaptors to reduce the overall size of the adaptor, which could in itself be costly.
  • the connector housing may comprise a recessed OBD connector part arranged to receive data from a vehicle OBD port and a data transfer part for transferring engine data from the OBD port to the transmitter housing, wherein the height of the data transfer part is less than that of the connector part.
  • the connector housing may be less than 20mm in height. More preferably, the connector housing is less than 19mm in height. Even more preferably, the connector housing is less than 18mm in height. Yet more preferably still, the connector housing is less than 17mm in height.
  • the smaller connector housings are less likely to interfere with driving. These heights are particularly advantageous when the adaptor is connected to an OBD port located in a coverable recess in a vehicle.
  • the transmitter housing may comprise a wireless transmitter.
  • the wireless transmitter comprises a BluetoothTM transmitter.
  • the wireless transmitter increases flexibility in terms of the location of the transmitter housing and, again, minimises the risk of any physical interference with driving by not requiring a physical connection.
  • BluetoothTM is a particularly suitable form of transmitter.
  • the transmitter housing may comprise a physical connection operable to transmit data.
  • the data cable may be substantially flat. Flat cables are particularly advantageous when the vehicle OBD port is located in a coverable recess. A flat cable is also beneficial in terms of tidiness and storage space when the adaptor is stored.
  • the connector housing and transmitter housing may comprise attachment members so that the connector housing and transmitter housing can be releasably secured together. The attachment members allow the adaptor to be neatly stacked either when in use or when being stored.
  • the transmitter housing may comprise at least one attachment clip and the connector housing may comprise at least one attachment wing which can be secured in the attachment clip.
  • the at least one attachment clip is adapted to receive a cable tie by means of which the transmitter housing can be secured to a vehicle.
  • the clip and wing attachments are particularly convenient, secure and consistent attachment members. Two attachment clips and wings can provide a more secure attachment mechanism.
  • the clip can be adapted to receive a standard cable tie, piece of string or the like which can be used to fix the transmitter housing to part of a vehicle.
  • the data cable wraps around at least part of the connector housing and/or or the transmitter housing with substantially no slack. With such a data cable, the adaptor can be neatly stacked, either when in use or when it is being stored.
  • the data cable may be separable from one or both of the transmitter housing and the connector housing. This increases the convenience and flexibility of the adaptor.
  • a vehicle may comprise a vehicle diagnostics port and such an adaptor connected to the port.
  • the vehicle diagnostics port may be located in a coverable recess and the connector housing may not protrude out of the recess when the recess is uncovered.
  • the recess may be substantially covered by a recess cover.
  • larger conventional adaptors can protrude out of the recess in such a way that it is not possible to cover the recess.
  • a larger adaptor within eyeshot when driving might simply be unsightly.
  • FIGs. 1 to 4 are a perspective, left (side), front and plan views of a customised adaptor in the unstacked (or extended) state;
  • FIGs. 5 to 8 are perspective, left (side), front and plan views of the customised adaptor of FIGs. 1 to 4 in the stacked (or stowed) state.
  • FIGs. 1 to 4 show a vehicle diagnostics port adaptor 10 in its operational, extended state.
  • the adaptor has a connector housing 12 having internal male connection pins 14 which are arranged to mate with corresponding female pins in a vehicle's On- Board Diagnostics (OBD) port (not shown).
  • a data cable 16 in the form of a flat and flexible fly lead carries engine data from the connector housing to a separate transmitter housing 18.
  • a wireless transmitter (not visible) in the transmitter housing 18 transfers engine data wirelessly to another unit, such as a smart phone or dedicated display unit (not shown), for further processing.
  • the connector housing 12 has a lower recessed part 20 that is substantially the same height as, and connects with, the vehicle OBD port.
  • the connector housing includes an upper, data transfer part 22 that is significantly smaller in height than the recessed part 20. As such, the connector housing 12 has substantially the same overall height as the OBD port.
  • the data transfer part 22 accommodates the data cable 16 so that data can be transferred from the connector housing 12 to the transmitter housing 18.
  • the data transfer part 22 has two lateral (or transverse) wings 24 which can be used as part of an attachment mechanism to secure the connector housing 12 to the transmitter housing 18 in a releasable manner, as will be described below.
  • the transmitter housing 18 is formed of a lozenge-shaped shell and defines an internal hollow cavity.
  • a cable guide 26 defined by two parallel longitudinal ridges 28 is provided on the surface of the transmitter housing 18.
  • Two lateral attachment clips 30 in the form of hooks, clips or loops are provided on the underside of the transmitter housing 18 and are arranged to cooperate with the wings 24 of the connector housing 12 to secure the adaptor 10 together.
  • the loops 30 can also receive a standard cable tie, by means of which the transmitter housing 18 can be secured to the vehicle.
  • a printed circuit board (PCB) (not visible) provided within the cavity controls overall operation of the adaptor 10.
  • the PCB is in communication with the wireless data transmitter (not visible), which, in this example, is a BluetoothTM transmitter.
  • the LEDs 32 denote several different operating modes of the adaptor 10 as exemplified in the following table:
  • the flexible fly lead 16 allows engine data to be transferred from the ECU via the connector housing 12 to the transmitter housing 18.
  • FIGs. 5 to 8 show the adaptor 10 in the stacked or secured state.
  • the adaptor 10 can be stacked for storage and/or during use as desired.
  • the fly lead 16 is neatly wrapped around the transmitter housing 18 using the cable guide 26, 28.
  • the length of the fly lead 16 is such that the connector housing 12 can complete one or several orbit(s) around the transmitter housing 18 so that it can be stacked and, when stacked, there is negligible slack on the fly lead 16 so that the adaptor 10 is neatly secured.
  • the wings 24 on the connector housing 12 cooperate with their corresponding clips 30 on the transmitter housing 18 to secure the adaptor 10.
  • the dimension of the adaptor 10 can be chosen to meet individual requirements. For example, the dimensions of the adaptor 10 may need to be smaller for some vehicles than others and may need to be larger if additional components, such as memory, are required or if a larger PCB is used.
  • the overall height of the adaptor 10 when stacked is 31.5mm, its maximum width is 45mm and its maximum depth is 26mm.
  • the height of the connector housing 12 is 16mm and the height of the transmitter housing 18 is 15.5mm.
  • An adaptor 10 of these exemplary dimensions would be ideal for a car having its OBD port located in a coverable recess, the depth of which is not much greater than the height of the OBD port.
  • the height of the connector housing 12 is only slightly greater than the height of the OBD port and, as such, does not protrude from the recess in such a way as to inhibit or prohibit covering of the recess.
  • the transmitter housing 18 can be conveniently located adjacent to the recess. Since the data cable 16 is substantially flat, although it might obstruct closure of the recess to some extent, it should still be possible to cover the recess securely. Alternatively, a small opening for the cable 16 can be made in the recess cover if desired.
  • the transmitter housing 18 can comprise a wireless transmitter to transfer engine data to a separate device
  • the transmitter housing may, instead, have a physical connector such as a Universal Serial Bus (USB) port.
  • USB Universal Serial Bus
  • the data cable 16 can be permanently connected to both the connector housing 12 and the transmitter housing 18, it could be releasable from either or both.
  • the data cable 16 can be detachable from the transmitter housing 18 so that the transmitter housing 18 can be removed from the vehicle while the connector housing 12 remains installed to the OBD port. This can be convenient if the OBD port is located in a relatively inaccessible part of the vehicle.
  • the adaptor 10 could perform as a data logger, by which engine data is recorded during a journey and is then transferred to a separate device after the journey.
